p.1 #1 · p.1 #1 · Zeiss Contax 100/2 AE or MM


I was pricing Zeiss 100/2 macro lenses and came upon a bit of information in this thread: http://www.fredmiranda.com/forum/topic/1036580 So, what't the difference optically or functionally, anything?

PS: I looked for an existing thread here in alt. but couldn't find one.

Also is that a fairly average price? These usually go for $900+ in C/Y mount?

Thanks!

Also besides the speed of course, is there much difference between the Zeiss 100/2 MP and the Zeiss 100/2.8 MP? Price, IQ, anything?

I've had the Contax MP 100/2.8 for some time now.
Strong points:
- incredible macro and micro contrast
- great color rendering
- does 1:1 natively (whereas the the 100/2 does 1:2)
- no green/magenta LoCA that I have seen -- this is a weak point of the new MP100/2.
Weak points:
- some subtle blue/yellow CA can show up (when looking at 100%), both lateral and longitudinal.
- a bit heavier than the MP100/2 because of the longer focusing helicoid required for 1:1

I paid 500 GBP for my MP100/2.8, which is a fairly good price IMO. I've seen only slightly cheaper prices in Japan but they weren't interesting to me due to VAT.

I think the MP100/2.8 and MP100/2 must have quite a lot in common. The MTFs are very close. I think the colors of the 100/2.8 will be slightly cooler than the 100/2.

Regarding the Contax Planar 100/2 (non-macro): there might be no noticeable difference between the AE and MM versions. The MP100/2.8 was only made in AE version, but it does not have the "ninja star" aperture. I think the Planar 100/2 will probably not have the ninja star either in the AE version. The ninja star is perhaps only seen in the f/1.4 lenses (35/50/85).

Final note: Paul Yi prefers the Contax Planar 100/2 over the new Zeiss MP100/2. The rendering is a bit different. http://www.fredmiranda.com/forum/topic/1009161/32#9901631

I think the F2.8 is 1:1 and the modern F2 is 1:2.

Looking at the MTF charts though, I would go for the modern version if I could swing it. However, if the price difference is big enough, I might just shoot for the older one.

If you're using the modern F2 natively though with aperture control and full EXIF, then maybe the newer one as well... lots of factors.

By that auction I linked it looks to me like there's almost no price difference tho. They both come in at around $900 used. My currency calculator doesn't have GBP so I have no idea what 500 of them are in US Dollars. He says it was an exceptional price so I guess $750 or $800?

The contemporary Zeiss ZE/ZF Makro-Planar 100/2 is a 1:2 macro lens, with MFD = 0.44m. The Contax Carl Zeiss Makro-Planar T* 100/2.8 is a 1:1 macro. Of course, the Contax Carl Zeiss Planar 100/2 AE & MM lenses were not macro, with MFD = 1.0m.

Check with the Leitax site if you're thinking you might want to use a Leitax mount kit, http://www.leitax.com/Zeiss-Contax-lenses-for-Canon-cameras.html

Some other AE/MM distinctions are discussed here, http://photo.net/equipment/contax/shea-lenses

I have the C/Y 100/2 Planar and I find its OOF areas to be less strongly drawn than ZE 100MP and I think the C/Y 100/2 Planar has a faster rate of focus falloff and slightly cooler colors. Toothwalker, did a comparison of the two and found the 100MP slightly sharper wide open but similar at other apertures.

It's the other way round. Most of the AE mount lenses are not compatible with Leitax mounts.

Hmm, that's confusing. So, there's:

100/2 MP
100/2.8 MP
100/2 P (AE)
100/2 P (MM)
100//2.8 MS

Gee, any others? I didn't know there was a non-macro version till just now. Oh, and AE and MM are mount types? K, hmmm, feeling rather ignorant here...


The MS is only like a $250 lens tho right?

Thanks Benjamin. I just checked the Leitax site, and it's not quite as simple as either of us said. The first screen shot below shows some notes from the Leitax site. The second screen shot shows that there are Leitax kits for both AE and MM lenses with the C/Y 'wide' mount, and for MM only lenses with the 'narrow' mount. Go figure.

The Makro-Sonnar 100/2.8 is a Contax N lens (with AF) which needs to be converted to EF mount by Conurus in order to use it on a DSLR. It's a different optical design, but similar enough to the C/Y Makro-Planar 100/2.8.

There is a Contax Sonnar (non-macro) 100/3.5 (great lens too) which is in the range of $250.

So it comes down to:
Z* Makro-Planar 100/2
C/Y Planar 100/2 (AE/MM)
C/Y Makro-Planar 100/2.8 (only AE)
C/Y Sonnar 100/3.5
The Contax N you probably don't want to consider.

AE = Auto Exposure
MM = MultiMode, meaning that the aperture of the lens can be set by the camera in Shutter Priority mode (whereas AE only supported Aperture Priority of manual). MM lenses are recognizable by a tab on the lens mount, which communicates the maximum aperture to the camera, and the highest f/number on the aperture ring is green (the rest of the numbers are in white).

This seems to refer to the Canon mounts that sit on top of the original mount, not the complete mount swaps that are necessary for Nikon etc..

OK, thanks for all the info so far guys! Very appreciated!

I just bought two of them. Both are the 100/2.8 MP. They had the N mount 100 too but I think they wanted too much for it ($350) and like yall are saying it's a PITA to get it working on cameras besides the N1.

I've taken some pics with one already and just from the camera's display screen it sure does have that subject-isolation zeiss-rendering thing going on. And in shots I wouldn't have expected it too. Nice!

Yes, of course. OTOH, the Leitax kit for a Nikon to Canon lens mount change does require a complete mount swap, so it all depends...

So you are saying you bought two 100/2.8 C/Y lenses for LESS than 350$ each? And that is US Dollars? And you didn't buy the N-mount version because it cost 350$? If I really got that right, I would love to visit your used lens store.

No no... I mentioned three lenses. The two 100/2.8 MP (C/Y) I bought (I paid fairly normal prices for Japan... perhaps a tad cheap) and the N mount 100/2 AF which I didn't buy because I thought they wanted too much and it's a PITA.

BTW, So far all my tests put this lens very far ahead of any other macro lenses. I keep taking a picture and pausing to say "wow" about 4 or 5 times before I take the next. Seriously cool lens! I didn't think it was gonna be this good to be honest. I figured it would only be slightly better but with that zeiss drawing style - nope!

Interesting, I wonder if the 100/2.8 AE can be adapted via Leitax to Sony.

I dunno what Leitax is but if you're asking if there's a C/Y adapter for NEX then yes there is. For Sony Alpha there may be I dunno. But that's common information so I assume you're talking about something completely different? What, like a conversion kit or something?

$350 is a good price for the N Makro-Sonnar. The conversion by Conurus is more expensive than that, at US$619. He's been raising his prices apparently. One of the reasons is that ebay sellers have been buying up all the cheap Contax N lenses and increasing prices for all of Conurus potential costumers.

@Jae: According to the Leitax Contax for Canon page, the C/Y 100/2.8 isn't compatible because the screws are in different locations from the other lenses. The same will be true for the Sony mounts then. It's most probably possible to still do a mount swap if you drill holes in the right places, or have someone do it for you. Jim Buchanan may also be able to do the conversion for you.

@Bif: Leitax provides high quality mount replacements for many different camera and lens mounts. Not really necessary for Canon since there are cheap adapters, but other camera mounts don't have space for adapters due to the longer registry distance, but Leitax mounts solve this problem because they replace the original mount and provide the correct registry disance. See leitax.com.

Anyway, I can fully relate to your experiences with the lens. Many shots that I take with it also make me go "wow".
