The Zeiss aperture settings snap into place much better, and I, for one, find that a huge plus, as I don't feel the need to double-check my aperture setting before each shot.Ĭheck back soon for a continuation of this test. That makes it a pain to use after about f/2.8. The Zeiss is also much easier to use, as the Mamiya gets darker on the 645AF as the lens is stopped down.
The skin appears a bit softer with the Mamiya, but I have a feeling that has something to do with the better micro-contrast of the Zeiss. The Mamiya seems to render colors a bit warmer than the Contax. For my taste, the Contax wins in color and contrast. For now, though, this should give you an idea of what these lenses look like side-by-side. I'd also like to be able to test the flare resistance of these two. We shot Fuji 400H at EI 200, and I would have preferred for that to be EI 100 in this situation. That meant we couldn't go much beyond f/5.6 without things getting shaky. Storm clouds rolled in about the time we started shooting, so it was quite a bit darker than I would have liked. This is a quick and dirty test, and I would like to do more testing in the next few weeks. The Mamiya-Sekor "C" 80mm f/1.9 is on the right. I am mistaken - I don't have the 45mm, i have the 55mm.The Contax 645 with the Carl Zeiss 80mm f/2 is on the left in all of these.
I would not mind looking at your sharpest 45mm image. If you want any specific examples of the 120 or 45 let me know. The 35mm distagon would be a great lens (super sharp). I have owned the hartblei super rotator and would not recommend it unless you obviously want to do tilt/shift work (its fun, but just didn't get much use out of it). this was stopped down to like f/22 I think That 120 is by far the 's like a surgical instrument. I currently own the Zeiss Distagon 45 (it's sharp), 120 Makro (it's insanely sharp) and the 210 (very nice as well).

Have you had any experience with any of the following other than the 80mm? I am interested in sharpness across the frame at the widest aperture possible (not necessarily looking for sharpness wide open unless.). Steel Chen gave me his opinion on three lenses he thought were sharp wide open.
I posted the following list on the Adapted Lens forum and got no response. I am using some Pentax 645 lenses but would like to explore other brands. I'd like to extend my lens lineup via adapted lenses. Steel Chen is developing a Contax 645 AF adapter for the GFX 50s. I can't address your question but I have one for you if you don't mind. Guessing I am missing something fundamental beyond the sensor resolution.
The question is: with the D850 (46MP) being released soon, what are thoughts on Image Quality between this lens on D850 (46MP 35mm Full Frame) vs same resolution on MF digi back? I did shoot with a Aptus 75 at one point and it was 6666*4992 = 35MP.
I miss the medium format magic though, and am considering buying a Contax body again just to shoot this again in its full glory. Contax 645 Medium Format Camera with Plannar 80mm f2 Lens All Cameras come with a 6 month warranty In this kit: 1) Contax 645 Medium Format Camera 2) Contax.
This camera should be used with Manual focus only and then it really is a pleasure to use. The kit comes in a good and fully working condition, except the auto focus is too slow and hard to work with. I have since sold the Contax body and have used the lens on my (aging) DSLR (12 MP).

Vintage camera store in Delft - Here we have the highly sought after Contax 645 medium format camera with the Famous Carl Zeiss planar 80mm with fast f/2.0 aperture. I LOVE the 80mm and was reason I got into the Contax system to begin with. I have a Contax 80mm f/2 lens which I have used on both a Contax 645 as well as my Nikon D700 (via a Nikon F mount "JAS" autofocus adapter from steel chen).
