And same warning I have given earlier: Under any circumstances I don't recommend 50 or 85 planar to anybody, they have their faults and if you don't mitigate the focus shift and understand these are not meant to be shoot close neither wide open (and specially not combined close and wide open), one will just be disappointed.

Samuli, could you please post some samples of focus shift with the 50 1.4.
I greatly appreciate your ability to fuse your technical knowledge with an artistic eye. Where I come from a fine arts background in education and a graphic artist, and art therapist as occupation-I'm so technically challenged that I use my vision to guide me and then use trial and error to get to my finished product-the print. The good thing is that I don't feel the need to understand everything and trust and use my intuition. In addition I have found that as much as you want to control your medium, if you can loosen up a little and let things happen you sometimes get the most wonderful unexpected results-kind of like improvisational jazz. On the downside, it limits my photographic repertoire, and it probably takes me twice as long to get where I want because of my lack of technical analysis.

Samuli - Would love to pickup a 21ZE, but I think it's a bad idea to buy a lens I'll only use when traveling.
Think I'll bring all my lenses, give them all a shot at paradise. Still undecided, but you're right, I do also end up bringing more lenses then needed.


Best,
Adam

P.S. Still think the 50 MP ZE is the best 50 I've ever used to all above who've been writing about it.

Anyone here use the zeiss 35mm and 28mm. Are they too close in focal length to justify owning both? Thanks

Samuli,

The picture you linked here by Mike Lucas shot with the 1.4 of El Capitan in Yosemite is shot at f8 with distant infinity subject and the bokeh differences between the 50/1.4 and 50 MP would not come into play here. If you took the same shot with the 50MP it would look very much the same except slightly sharper and more consistently sharp across the frame.Color, micro-contrast, etc. would be the same.

Wayne,

In addition to Boris photos, I have hard time finding any 50MP landscapes showing shape and volume of photographed objects. According to many side by side comparisons most of the 50mm primes and good zooms shoot exactly same looking photos. In practice I have found otherwise, but without buying 50MP, can't argue about this since I have to just base my evaluation just to general lack of images, which have traditional Zeiss-look.

wayne seltzer wrote:
Here is a landscape shot I took the other day with 50 MP. If I took the same shot with my N 50/1.4 it would look very similar but would not be as sharp and would struggle to keep the same sharpness from front to back in this scene.
If you think this shot is lifeless or the other vague term people here seem to use, clinical, then let me know.


Wayne, unfortunately this shot more or less re-presents what I'm talking about, there is no feeling of depth (the background doesn't clearly appear to be far away, neither the steps/levels in waterfall doesn't distinct from each other in depth), volume or shape (the rock on right of main waterfall tries, but really doesn't get there). Maybe it's the murky light, which doesn't let shapes and volumes to be formed, so it's highly probable that Planar picture is just similar.

wayne seltzer wrote:
I will also try to find Lotus's post where he posted the two comparison shots which people here got wrong trying to identify which one was taken with which lens.
I will also try to post some comparison shots since I have both lenses.


If it was the test shots from backyard where there wasn't much objects on different distances, just some tree etc. all about same distance from camera (which in my books makes the test very little interesting, since it doesn't represent dynamic situations we usually shoot, good lens test thou if that is the goal...), I remember it faintly.


wayne seltzer wrote:
Thus I see benefits of both 85 and 100 and would use them in different situations.


I'll have more or less same approach, depending where I go and what I plan to shoot I often make the selection already at home, I don't see much point bringing both unless I have feeling that I need to shoot flowers/rock details/panoramas/"other only 100MP stuff" and medium distance tele shots with difficult background (which is what I shoot A LOT).

One thing I have criticized in 100MP is the "short focus throw on normal shooting distances", this forces me to use in handhold situations 85ZE most of the time. For 10-30m (30-90 feet) distances I just cannot focus accurately with 100MP and therefore I'm limited to 85ZE. I even considered getting Contax Planar T* 2/100 C/Y if it would have longer focus throw, but then settled to use 85ZE, since I don't shoot much handhold and I have way too many 85-100mm lenses. Critical focusing accuracy and repeatability is not meaningful on many situations, but I always aim for big print as my end product and in those the slight misfocusing can be easily seen. This is very personal, I'm sure somebody prefers "fast focusing" (for me it just takes more time since it's impossible to turn enough small increments).

Instead of arguing what is best lens (since there isn't one), for me it's more important to know you equipment and use it's strengths as advantages and when knowing weak points avoid them.


prashant wrote:

How do you?


Prashant, Live view + movie mode. If you need to shoot handhold then you need LCDVF or other similar product or ultra stable hands if you use the point&shoot "extend your arms" shooting position

I always shoot in M-mode and I keep Av-mode aperture at f/2.5 in order to focus with biggest aperture, which doesn't have focus shift. Then when I shoot I focus by turning camera to Av-mode (if my shooting aperture is too small for accurate focusing), focus, turn back to M-mode and shoot. Of course if I shoot at f/1.4-2.5 range I skip this Av-focusing and just focus in M-mode.

camershy wrote:

camershy, I don't have any sample shots, why I would have saved them? It doesn't look anything special, it just looks like your subject would be 2 meters from you and you would focus to 1.95 meters distance (for both 1.4 Planars the plane of focus moves towards camera when aperture is closed. Amount of focus shift depends shooting aperture and focusing distance. Generally it's caused by uncorrected aberrations wide open (and they get corrected when you close down).

May I ask why you could not use 21ZE outside holiday? I first had problems finding subjects for 21mm, but it has gotten easier by time, thou one needs different mindset for shooting this wide lens. For a long time my widest lens was 25mm Distagon on 1.3x, and I had very little use for it...

Adam, best in what sense? As average for all generic shooting situations (which I would agree - based on same criteria 17-85 zoom is excellent if we ask from wider audience, which I'm sure most in Alt forum don't consider very good...) or subset of some situations or just best in all possibly imaginable situations? Seems that any hint of having opinion to "other direction" requires one to write a 1000 page book, so I'm not going to let you this easy from blurbing this kind of generic statement (and this was joke - no need to answer)

Thanks a lot for your efforts, Samuli! The 50/1.4 seems to do what the 35 Distagon does, but at larger distances. I see the same very smooth blur from the 35 at medium short distances and stopped down to f/2.8-4. This is at f/2.8:








I just sold my two Nikkor 50:s and I'm getting the Planar tomorrow. While most people seems concerned with IQ at close distances, I really don't. And those sort of landscapes (or similar) with a depth is exactly what I want to do, but perhaps more urban style.

Makten, great presentation of what I expect from Zeiss lenses: feeling of depth, objects in photo have clear shape and volume. Fugly bokeh on top left, but can't have it all - well maybe with you your Biogon 35 also bokeh can be beautiful AND still have the Zeiss look.

Samuli,

Thanks for your responses. I think you like to use shallower DOF type shooting to isolate foreground trees from the background trees and show depth that way. My picture and Boris's shot are more typical landscape examples where there is a large DOF which covers both foreground objects and the background objects. The Mike Lucas El Capitan shot is the same time of large DOF type of landscape shot.
To me the objects within the DOF of any Zeiss lens show great 3-d and are not flat looking. If I show you crops of the rocks with the moss, they don't look flat and have dimension.
Depth in a landscape scene can be accomplished without using foreground/background isolation technique that you like, and depends on composition and lens focal length etc.
I will take some narrower DOF landscape comparison shots which you seem to shoot exclusively and the same for some statue shots which is close to what Philippe normally is shooting.
This type of shooting introduces the differences in background bokeh rendering which I think is the main difference between the two lenses. We can compare the transitions in and out of focus plane too but I don't believe this is a big difference for this type of shooting. I believe it is the bokeh difference influencing your preferences.
I agree with your statement about not arguing which is best because it can depend on things like shooting style, types of shooting, etc. so yes, I like to be clear about the differences and leave it up to everyone to make the choice best for them.

Took a half day off from work and went on a roadtrip

I bought the 21ZE and 35ZE.
The weather is really bad, so I haven't had the chanche to test them yet.


@Samuli:

I looked at a lot of photos made with a 50mm planar today and I have to agree with you.
They look less 'aggressive' and often seem to have more depth. A littlebit more '3D' than the 50MP. It seems to do it more easily.
This doesn't mean I like my 50MP less, it has another look to it and does macro well.


Thanks for the insight. I never really looked at the 50ZE 1.4

Wayne, let's not get stuck to this narrow DOF. Majority of my shots use this technique but if you read current 3D thread they blamed me introducing new kind of 3D-look (which definetly is not new, those people just had not seen much Zeiss photos, except Paul's park bench shots...) due to using f/11 shots showing 3D, I did that just to demonstrate that DOF/bokeh has almost nothing to do with 3D-look (depth, shape & volume).

It may be your resizing and sharpening techniques causing lack of 3D in your waterfall, but the light still seems pretty bad to me.

I'm well aware of Mike's shot having nothing to do with DOF, it's all about DOF rendering style - the Dome clearly has shape and volume. Also Boris' Norway shots make sure viewer is able to see what is the shape of the mountains.

In this respect I agree that it might be nice to have some sort of side-by-side "gallery" of various lenses, however this requires quite lot of work, and is very difficult to execute - interesting and informative comparison shots cannot be taken in boring constant light (e.g. strong overcast or direct midday sunshine), but any other lightning causes easily differences to photos. In real life shooting (not any damn comparison shots) I aim to press the shutter when edge of cloud goes just past my foreground subject, which typically creates most interesting lightning.



Too much talk, we need more photos. Time for post something from 100ZE - f/4, 1/160s, 7 image panorama. I have had to create a lot of nature images in poster size lately, I'll try to find some other examples as well. For this kind of photos I can't imagine better lens than 100MP, no distortion and homogenous sharpness across the sensor. Don't look much in this webthumbnail size...



...but here is link to size in which I watch my photos, and why I call these miniature images as webthumbnails --> 2560px wide. original size is somewhere about 12000-15000px wide.

One reason why I shoot a lot with 100MP, but don't post a lot of photos here or my site, is that I shoot quite a lot of nature posters with it, and they really don't work well in websize. I have shoot them to stop people and make them thing (nature preservation stuff). And they seem to work pretty well on that. It's funny watch people walk by, then walk back to see "what the heck was that", then they move their heads like trying to see behind trees... general comment has been that there is really strong feeling of watching forest, not a poster, which kind of was my goal when planning and shooting this kind of images. Image below is one of the "nicer" ones, quite often I have some human elements ruining the nature in these photos.

This image is in poster at corridor wall, it's in size roughly 2 meter by 1.3 meter (about 6 feet by 4 feet), and it's still over 300DPI, so quality is absolute top notch no matter how close you watch. For 2 meter wide print f/11 was quite good selection, even depth of field is very very narrow at f/11. 100MP high bokeh contrast (compared to 85 planar for example) works pretty well, since if you look the poster far away it appears to be sharp overall, but when you come closer the trees in middle of DOF really stand out from the background. For web or computer screen this would have to be shot somewhere around f/2.8-4 to get similar effect.

Samuli,

Sure lighting can have an effect on shape and 3-d ness of an object. My waterfall shot was taken in the light rain and has a darker moody feeling of light to it. Overcast light is better for bringing out the color of the green moss and avoids having hot spots of much brighter light being intermingled with darker parts.
The size of my web shot and the smaller size of the rocks in the stream make it harder to see the smaller scale of volume/shape and definition which is still there, just not on the scale of a larger object in a larger webshot like the El Capitan shot and Boris's shot. Mike's shot seems like it was taken in the middle of the day not near sunrise or sunset when the light is interesting. The midday overhead lighting does highlight more the texture in the rock face. Some of your last daytime 100MP shots look like they were not taken in any special kind of light and along with the pano shots seem to lack any purpose of composition and just look like a point-n-shoot shot into a random forest of trees.
Let's not use lighting as way out of comparing lenses, that's BS to me.
If you take the same shot of El Capitan in the same light with the 50 MP I can assure you that you would not be able to tell the difference unless you pixel peep and see the minor increase in sharpness across the frame.
I am arguing this point with all you guys who don't have both lenses. Pretty pathetic. The one other person here in the forum, LotusM50 who has not only both lenses and also a ton more zeiss lenses than most people here has previously confirmed my statements about the differences.
You have already stated your exit strategy also by stating comparison pictures are not valid and not real and useless, blah blah blah.
BTW, pls. explain "traditional Zeiss look" that is a good vague term too and how some Z* lenses don't have it.

Makten, I like the foreground part of your car shot but not the ugly bokeh in the tree-skyline in the back.
If you like ugly bokeh like this, then definitely go for the 50/1.4 over the 50 MP.

Under challenging bokeh situations like backlit tree branches/leaves, the 50/1.4 will render much uglier/busier/harsher bokeh than the 50 MP. It is the opposite situation to the 85/1.4 and the 100 MP where the 100 MP will have the uglier bokeh.

Samuli - You may be right about finding subjects to shoot with my 21mm.... Though I feel that if I'm going to buy a lens, I should be able to use it for work. And in my line of work, I rarely if ever see a need for 21mm.. That's the only reason why I feel I shouldn't buy the lens, but in all fairness I could get by without any of my Zeiss glass, so this is why I'm still on the fence about the lens. I'm really hoping one comes by at a price I cannot refuse, before the end of next week.

----

OH, and I'll totally justify in my own way what I mean about the 50 MP ZE.

I use my Zeiss glass for work and play. I keep a folder called Zeiss Samples on my desktop, and I only fill it with photos where the lens rendering moves me. Even if the composition is bad, or the persons squinting etc..

The other day I was looking through this quite large folder now, and noticed a few shots that really stood out. A couple of portraits and a building shot. I checked the EXIF as I thought they may be 85ZE shots for there bokeh and 35ZE shots for there landscape realism. It turns out, they were from the 50 MP ZE.

Now I'm not a landscape photographer, so when I wrote that it was the best 50 IMO, I was taking into consideration what I use a 50mm lens for. I use a 50mm to take shots of people with a bit more info in the background, both close up and half body. I also use a 50mm for quirky walk around shots (and now I have macro abilities), as well as building and the odd landscaped shot.

So I liked the 50's richness of colors, and I liked it's out of focus areas, plus sharpness wide open. This was for the first portrait. (head+shoulders crop)

The second portrait had this lively bokeh, really made me smile. (half body crop)

The third was a lookbook I shot, the 24-70L couldn't get the eyes sharp and detailed at f/11 I figured try the Zeiss. And when I zoomed in to compare the two images, I realized the 50 MP ZE was gold. I can see the fibers in the eyes on a full body shot of a model at f/11 something I couldn't get with my 24-70L. (full body)

This building I was shooting, again not a particularily nice composition, but it really jumped out at me, like woah, I'm just standing on the street looking at it, and not a picture of it. (near infinity or infinity)

So for my needs this 50 is a perfect all around lens. Samuli you have to understand though, I picked up the 100 MP ZE first, and was amazed by how different (better) the focusing was from a Canon L to a Zeiss.. Then the 50 MP ZE, then the 35 ZE, then the 85 ZE... So it went from shitty focusing, to makro short throw but ultimately good focusing to wide angle semi better focusing to the 85 which was good for focusing. What I guess I'm getting at is, since I started with two macros, I got use to the idea of short rotations in the mid ranges, and it doesn't bother me as I assume it bothers you.

BTW, as a side note, I have this shot taken with the 5DII and the 100 MP ZE, at around f/5.6 I think, and I just took it as the model was still around and I wanted to use the lens if even for 2 crap photos, as I was using the 50 MP all day. Anyway, I took the shot and when I got home and zoomed in on the detail, it really reminded me of this RAW file someone posted with the Leica Medium format camera. The detail, color and overall beauty was actually in the file, and again I've shot with Canon for a good many years now, and I've never once seen this level of realism and detail.


I know you didn't really need a response but I hope this helps to clarify my bold, no explanation statement.


Oh, and I've had a really brief try with the 50 1.4 ZE, and although I can see it's charm, as I do have the 85ZE and know it's charm. I still think the 50 MP ZE wide open makes a better headshot/portrait lens, you just have to know how to shoot with it. As I will agree that like the 100 MP ZE, it doesn't always give the best bokeh. Though again, I really did surprise myself when I took a look in my folder and seen all those 50 samples.

Wayne, for the brief bit of time the 50 1.4 ZE was in my hands, I found that the bokeh was on par with the 85ZE, though it was probably the subject I was shooting etc.. The 50 MP ZE in my opinion does create good bokeh, but can also create bokeh like the 100 MP ZE, though both lenses can do amazing bokeh if the situation is just right. Back a while ago John Black was doing some tests with a 90 Leica M, and a 100 MP ZE, and in both cases the bokeh was amazing.

I guess what we are failing to realize is:
A) Our views on bokeh are subjective
B) The way we shoot, would give us a totally different impression of a lens vs the way another photographer shoots.

I really should start posting samples, but I rarely post my jobs/work online. And the personal shots I've been taking as of lately have just been snaps in comparison to what's being posted here currently. I'm going on vacation, so hopefully between the sunburns and water sports, I'll be taking some worth while shots.


BTW Samuli that forest photo you posted is pretty amazing, I'm sure printed to a nice size it's just breathtaking.

Thanks for your insight Adam, since you are busy on holidays I am writing while I'm in Thailand on the way to Phi Phi island with my fiancee too.

I have been in Bangkok on business, and found shots that I needed to take were with the ZE 50MP, ZE 85/1.4 and the ZE 21 for factory shots.

I have the full range of ZE lens, that I pretty well use exclusively now. I now keep the ZE 50MP on my 5DII also. I use canon L's now for action horse or shots requiring AF.

Samuli, thanks so much for all the information. This thread is amazing wealth of information.

Amazing shots Samuli.

Wayne, the point was that this was supposed to be side by side comparison shot for flatness etc. I have photographed mossy streams quite a lot and completly agree with you regarding this, also "dark" lightning is the key to get the water look like what it is in your shot. If the key would have been to show flatness/non-flatness then the exposure should be selected so that rocks would have been at least 1 stop lighter.

The size of my web shot and the smaller size of the rocks in the stream make it harder to see the smaller scale of volume/shape and definition which is still there, just not on the scale of a larger object in a larger webshot like the El Capitan shot and Boris's shot. Mike's shot seems like it was taken in the middle of the day not near sunrise or sunset when the light is interesting.


I don't see the point in here - lenses can have different characteristics on different shooting distances, so if you are going to do good side-by-side evaluation you need medium distance (your shot) and infinity (like Boris shots) and something in closer distance as well. The comment I made about lightning was for comparing flatness of two lenses side-by-side, not generally for all photos in the universe.

The midday overhead lighting does highlight more the texture in the rock face. Some of your last daytime 100MP shots look like they were not taken in any special kind of light and along with the pano shots seem to lack any purpose of composition and just look like a point-n-shoot shot into a random forest of trees.


That first shot was ordered to be having sad mood and exactly in this size and presenting this kind of biotype (this kind of swamp). If I would like to have taken good picture from this spot (really hard to do, in middle of the swamp, with nothing special around) I would have shoot it one month later (the ground much greener), in first sunrays after rain at around 20:30 sun shining to foreground of picture through the edge of the cloud...

The second shot took over 3 minutes to shoot due to large number of shots. I could have not shot all 59 images and create successful panorama in interesting light. Also "on the order" for this shot it was supposed to present sunshine, blue skye and warmness.

Like said, I have not shared these poster shoots since they simply don't work in web: they rarely are anything special in composition, more or less the point is to see them at the size they are planned to be used in location they are planned to be used with other surrounding elements (texts etc.) presented around the photos.

Also neither of these shots were lens side-by-side shots comparing rendering flatness, agains which I made the argument about light you used for this purpose, which now you seem to extend to every topic in earth. So to clarify: my comment about lightning was just about side-to-side shots for showing flatness/non-flatness/3D-look/what-ever-you-prefer-to-call-it, not as global comment concerning everything in universe.

Let's not use lighting as way out of comparing lenses, that's BS to me.
If you take the same shot of El Capitan in the same light with the 50 MP I can assure you that you would not be able to tell the difference unless you pixel peep and see the minor increase in sharpness across the frame.


Well, if you are going to take side-by-side shots presenting that 50MP is non-flat shouldn't the light be something, which can bring out the shape, volume and depth of the scenes/objects photographed? Or are you planning to have your side-by-side comparisons just to show sharpness and bokeh at large apertures?

I am arguing this point with all you guys who don't have both lenses. Pretty pathetic.


Well it's only grand - I just ordered one since some of the smaller posters I shoot I may get around by shooting only quarter/third of the shots with 50mm, which I have to do with 100MP. Let's see when I get the lens, am I allowed to talk the things like they are or is it still forbidden since 50MP seems to be "the holy cow". And now I'm really hoping that owners of 50MP just suck in resizing and sharpening ruining any Zeiss 3D from images...

The one other person here in the forum, LotusM50 who has not only both lenses and also a ton more zeiss lenses than most people here has previously confirmed my statements about the differences.


One thing you should understand that I don't thing anybody here has claimed that 50MP isn't overall better lens. You are again extending discussed topic to cover much larger subject than what the original discussion was about.


wayne seltzer wrote:
You have already stated your exit strategy also by stating comparison pictures are not valid and not real and useless, blah blah blah.


I'm not really getting you - badly executed side-by-sides are useless. The ones shot of planar or almost planar subjects, in light which doesn't even allow any depth, shape and volume to be shown in photo. Most of side-to-side shots are shot like this since sharpness is typically the only thing, which interests people. Also since 3D-look is highly subjective thing reviewers etc. try to avoid it since it will always cause "storm in the water glass", so I kind of understand why majority of side-by-side shootings are just simply useless for reviewing 3D-look rendering capabilities and concentrate boring sharpness stuff.


wayne seltzer wrote:
BTW, pls. explain "traditional Zeiss look" that is a good vague term too and how some Z* lenses don't have it.


tradional Zeiss look to me:
- large microcontrast
- not so large overall contrast (no blocked blacks like with Canon L)
- Zeiss colors
- Zeiss 3D look: scenes rendered so that scene has clear depth and objects/main object has clearly defined shape and volume

Based on examples available, we more or less only have some Boris shots having last bullet point done properly. I'm not saying that some of the Z* lenses don't have this last bullet point but to me it seems it's not that strongly visible in 50MP photos available. This may be also just because there are not that many 50MP owners and if they majority of them just take ultra narrow depth of field flower shots and the few who use lens for "normal" shooting let photosites like Flickr rape their photos and not do proper resizing and sharpening... most of the 50MP shots presented are "look how sharp it is" kind of, nobody of the owners praising the 3D look. So if the 50MP is the ultimate 3D-look lens, please show it in the pictures...

It is the opposite situation to the 85/1.4 and the 100 MP where the 100 MP will have the uglier bokeh.


Only if you close down to f/2.8 or so, the planar 85 bokeh can be pretty horrible wide open on this kind of highlights. Assuming we are talking about quality of bokeh, not quantity - it's quite easy at f/1.4 get the background so mushy that this goes away.
