I'll give him a tip of my hat for expertise. This is a forum, it's conversational. If we were all afraid of saying what we feel/think/dream of, then we'd have no conversation at all. It's ok to to be illogical sometimes.

On the topic of being illogical. The RX1, when it was first announced I was stark, raving mad. Fixed lens!?!? How could Sony so royally fuck that up? It's illogical. And then only later did I realise that putting a fixed lens on an RX1 gave it the best possible image quality they could (fantastic little camera for the wife). And to this day, everybody LOVES the little 35 attached to the RX1. But what happened when Sony gave us the interchangeable A7? we got a shit 35mm lens (I've used it to shoot a wedding, and a few corporate gigs, it's shitty). So we can all get angry at Zeiss or Sony or whomever for not giving us what we want. But I'm sure since they're experts they know better then us the limitations and compromises necessary to make a lens that people will purchase. And at the end of the day, we can speculate, get angry, have fun dreaming.. But we're going to get, what they wanna give us. And some will like it, and some won't. I hate the Otis because it's a MF DSLR lens, some people on here LOVE IT because to them, it's the best.

Personally, I'm not a fan of MF, unless it's RF MF. So unless the IQ is dangerously good, I'll probably skip on by without care. Since I already feel Sony sensors are awful and already detract from my love of the system.

False hope is better than no hope at all.

I look forward to the A10, nicknamed the Warthog, it ought to be tough enough. Lenses will be fly by wire though.



I hope so too All these nice Zeiss lenses with the A7 sensor are pointless. Let's see if Sony learned their lesson

This is transparently false.

Perhaps once you have added a non-trivial amount of photographs or knowledge to various threads you will understand how this forum works a little better. Right now you have four posts, all spent on a single argument that maximizing profits is the only logical thing a company can do, which is also transparently false.

Reiterating the same point is not the same as discussing it, ecarlino. You take for granted that the amorality of commerce is a fact, when it is not. (Yes, many 100-level classes teach it as such. This is to present ideas simply, as 100-level classes must. If you continue on to upper- or graduate-level courses, you will find that commerce does necessarily entail acts of morality.) I agree with Carsten that the pricing of products is a moral act, even if a small one. Furthermore, I think that it is folly to believe one can know "what the market will bear." That idea is good for academic discussion but not in commercial reality.

"Non-trivial" is a common term among all computer programmers, and increasingly so within intelligent communities on the internet, such as this one.

You are trolling, whether you intend to or not. You can either be treated as such or reflect upon how your behavior appears to others.

Cheers,
Jon

My purpose in reiterating the points is that they seem to have gotten lost in carsten's insanity as he has labeled me and my comments as something they are not.
Sorry to be cluttering this otherwise fine forum with this garbage, I tried walking away from the conversation yesterday.

No kidding - my degree is in CompSci and when I worked on Wall St you could tell the jerk-offs who went to MIT b/c they made sure to include "non-trivial" in every sentence. Whether or not it is becoming a more commonly used phrase, it wreaks of arrogance.

I don't disagree with the point you're trying to make but you might consider the context of your posts. I don't think you're trolling, but one might be forgiven believing otherwise since you've now posted a grand total of 5 times on this board and none of those 5 posts have much, if anything, to do with photography.

I'd respectfully suggest you think of this forum like any other informal social situation, physical or virtual. Sounds like you've lurked on the board for a while: great. However, you might want your initial posts to be more introductory: share some photos, talk about your camera gear, or at the very least just keep the tone more genial. Just as you probably wouldn't insert yourself into an ongoing discussion at a cocktail party amongst strangers with, "I'm not sure if you've ever taken an Econ or Marketing course...", it doesn't play well here.

Once you've posted here for a while, I'm sure you'll find that the tone of this forum does tend to ramble and go off-topic, and as long as it remains respectful, I don't think there's anything wrong with that.

I'm not sure whether to laugh or cry at this point, but clearly this has been the worst 'coming out' party ever (probably my own fault). I've always respected FM and those that post here because the conversation was always a bit more elevated.

Literally my first 2 posts made the point "I hope our favorite mfgs thrive" and I consider myself a "stakeholder in them". Probably very positive themes.

Unfortunately, that's gotten lost in an odd conversation that resembles a presidential debate and whether profits are moral or something (I don't even know anymore).

My only point in coming back today was to attempt to clarify the manner in which carsten characterized me, but that's probably only back-fired as well.

Oh well, back to my hole.....

I suspect that something about going from the Ivy League to Wall Street might have more to do with arrogance than the phrase "non-trivial." I also suspect that New York, Chicago, and computer science--all communities that speak rather bluntly--might have more to do with why this is a kerfuffle rather than a disagreement. Bluntness tends to go over poorly in plain text, especially when responding to perceived insults that were not intended.

Still, someone who thinks that having their comments being labeled as "emotional" validates ad hominem attacks is a troll, especially when that person has failed to show any rational basis for their comments--thus proving them to be emotional. At best, this trolling is unintentional and more suited to other forums.

I'm open to changing my mind. Reiteration of what I've already seen won't do that.

Cheers,
Jon

It's really a pity that ecarlino has had such an awkward start on FM. I also agree with his position on pricing, but these matters are like the debating the sex of angels, a completely useless and controversial subject. FYI ecarlino, Carsten is a very respected FMer with tons of knowledge about gear and a fine photographer. He might be sometimes opinionated on such "trivial" matters but I personally have benefited a lot from his gear expertise. So I would like to warmly welcome you to this forum and hope to see more posts from you in other threads

Jon, Al, Ed -
Perhaps the best way for me to get out from under this rock is to actually introduce myself and why I was even reading this thread -

I had been a Nikon guy for a decade and in 2013 I decided (after a half dozen or so photo trips/workshops) that carrying around 30-50 lbs of gear was getting crazy (I'm currently 42 and plenty strong, but I was finding that the gear was getting in the way). I owned the f/2.8 trinity, the TS lenses, the 400/2.8, the 105 macro and so on along with D3, D3x, D800. Even though my day job (starting out software developer then bond trader, now I manage my own funds) is very technical, I always preferred the 'art' in photography, not necessarily the 'gear'. So, I decided to downsize and sold the zoom lenses and was trying to figure out the fewest number of prime focal lengths that I could slim down to. I analyzed my favorite 1000 or so shots from the prior decade and found the % at each focal length and felt that I could reasonably cover everything with a 20, 35 and 85 primes and 70-200 zoom (for action, etc). So, I started buying f-mount primes and reading all of Lloyd Chambers work. I quickly became dis-satisfied with the Nikon 24/1.4 but fell in love with the Sigma 35/1.4 - but I always wanted to try the Zeiss lineup but couldn't get over the MF hump.

Then came the A7r. It convinced me to sell the rest of the Nikon gear and anticipate the release of FF e-mount glass. I returned the A7r because I'm tired of buying cameras every 2 years and with a few minor modifications (EFCS and hybrid OSPDAF) the next model should last me a decade (let's hope). It's been the hardest year to be without a camera (but I knew I wasn't going to be able to travel this year anyhow). So, I've spent the year going back over old photos and re-processing. I haven't posted any on FM yet, but my site is:
www.ecarlino.com
Specifically, the A7r photos are:
http://www.ecarlino.com/2013_san_diego

Currently, the site only has 'people' photos as I'm still processing my landscape/urban photos. But it's a start. My main target in taking photos are 20 frames throughout my house that are 3 feet tall x 5 feet wide that I try to replace annually (but sometimes getting 20 worthy photos in a year's time is not doable for me, so it takes longer). I do my own printing on an Epson 9900 that I have at home.

I look forward to Zeiss' FF e-mount MF line-up and using them on the next high-end FF e-mount camera.

I also look forward to new and interesting conversations with everyone about the art of photography.

There really is no reason to go back to any hole. I can see how you think this is the worst 'coming out' party ever and why you wanted to walk away, but if you learn from this experience I think you can enjoy participating. Here's how I see. You made a couple of posts that you meant to be and actually were positive, but you didn't realize they were on a somewhat controversial topic. People around here have ideas all over the map about our relation to manufacturers. Carsten responded in his typical straightforward/blunt slightly challenging way with a different view than you might have expected about this relation. You responded with an at least slightly condescending post about the nature of economics without realizing that some might take a different view on things. Carsten again responded in his typical way dismissing your condescending post. You then go off on Carsten with an ad hominem attack. You come back today and take a much more conciliatory tone, but, IMO, unfortunately make another gratuitous attack with the bit about everyone who uses non-trivial is a jerk. Jon tries to be helpful by reminding you this is like any other social situation when you step into a group that has known each other for quite awhile even if you have watched and listened to them you should pick your spot to step in.

To try to be helpful let me try to suggest where this went off the rails. Mistake #1 was the at least slightly condescending post about economics. I think this post was well intentioned, but you didn't realize that it might be controversial. Mistake #2 you attack Carsten for the number of posts he makes, the ADD references, and his use of language particularly non-trivial. This was the place where you alienated everyone and went completely off the rails. Like Jon said this is a social situation. Carsten has been coming to the same pub, if you like, for ten years. He knows a lot of people. Even more have had a beer with him once or twice. He's a regular, a fixture. People have put up with his quirks for a long time. Personally, I have disagreed with him as much as agreed but I think he is a great photographer and I respect him, but in this analogy I have had no more than had a beer with him.

You come into the pub for the first time and start a conversation with Carsten. You disagree. He razzes you. Then you call him names and say in analogy that he is drunk because he comes there so often, and then you wonder why people aren't welcoming you with open arms. You come back the next days and say sorry I got off on the wrong foot, but isn't that Carsten an ass. He says non-trivial after all. Not surprisingly to every one, but you perhaps, the reception is still chilly.

You can start again, however. I don't think we are a bunch that won't forgive a bad start. Maybe make an apology here without saying anything negative about anyone, but more importantly go to one of the threads and post a photo or two, talk about your favourite gear, and have some nice interactions with folks. Then down the road after you have "had a few beers" with people then jump into the more non-photo stuff including the market forces around the industry and realize these are controversial and try to be extra respectful. Things will go fine and it would be great to have you around. I don't mean this to be condemning or condescending, but maybe it will be seen that way. To me, however, you seem lost for why it went so badly and this is both my account of how that happened and how it can go much better in the future.

Steve,

Thanks for the feedback.
Hopefully, we can all enjoy each others photos taken with the new Loxia line (sooner than later)!

Indeed if Sony sticks to the current configuration of sensor toppings it's like they're shooting themselves in the foot. They need to remove that AA filter and minimize the glass thickness as much as possible.


Wouldn't that compromise the performance of the existing lenses?

Not necessarily. All AF lenses have some leeway past infinity and I would expect Sony to have somewhat anticipated this in their lens design. Also existing lenses (apart from the FE 55) aren't so great in the image periphery, and I bet it has to do with the sensor cover.

PS: Also if you take Nikon as an example, all their DSLR came with a conventional sensor cover including an AA filter. The D800E came with self cancelling AA filter, keeping the same cover thickness for the same reason you mention. Now it decided to remove the AA filter completely with the D810, with no ill effects as far as I see.

Wow, 3'x5': you're certainly printing big. I tried printing myself for a while but could never get the consistency I wanted and I found I just hated the process (of blowing time, paper, and ink to find that there was one little thing slightly off). I love the final results of prints, though.

I saw you had the Sony 35/2.8 when you owned the A7r. I'd be curious from you or others what you'd want Zeiss to improve in the Loxia compared to that lens (other than of course the max aperture).

At this point, I think we're just going to have to wait for Photokina, so this thread has something else to discuss.

btw - nice try editing your post to hide your true colors - good thing I replied before you changed it!

I've always been surprised how the 55/1.8 gets so much love (which it deserves) but the 35/2.8 gets treated like a little runt (barely even mentioned). I really loved that lens - especially as a walking around street/travel lens.

Even though it gets criticized for vignetting, I didn't find that particularly troubling (although I would like to know more about what Sony is doing in their software). My biggest concern with the lens was the extremely nervous bokeh in certain situations.

I'm sure the Loxia 35mm will have better IQ in every way, I'll be OK with a bigger size and more expensive price. I'm just nervous about MF for my primary walk-about lens. I'm planning on going with their MF for everything wider, because I'm almost always on a tripod in those situations and there's generally more DoF to work with.

Removing the AA filter doesn't mean the sensor stack thickness would change. I don't think the initial intent using the AA self-canceling filter was to maintain the thickness (more like to reduce the cost). What I am uncertain is that whether the optical thickness or the physical thickness would be the main cause for the poor edge/corner performance in RF WA (not clear in the lensrental blog). If it is the latter, there might be remedy for such (changing the former would really mess up the native lenses). I know both Maxmax and Lifepixel can offer different sensor stack thickness while maintaining the same overall refractive index (optical thickness). I am contacting Dan regarding this matter, and hopefully we might have a sensor stack replacement kit in the future if it's at all possible/feasible.

PS: I guess I'm willing to be the guinea pig for such experiment.

Fortunately, for all of us, Roger Cicala has an excellent write-up and explains everything:
http://www.lensrentals.com/blog/2014/06/the-glass-in-the-path-sensor-stacks-and-adapted-lenses

Short answer: the thickness of the glass in the path, even if it is perfectly clear glass, makes a difference in the optical formula - which is why Nikon had to have the self-canceling in the D800E - so the thickness would be the same as the D800.

Roger has lots of details and information and it is a very good read.

Well I think he used the same type of glass but with different thickness. In this case, the change in optical thickness and physical thickness would be the same.
