Hi,
Thanks for sharing your comments!
I actually think the Otus would have automatic apertures on the A7x if used with a Metabones adapter, it even allows for AF. The Mirex adapter I am looking for allows T&S but has manual aperture, but it would work with my Hasselblad lenses.
Getting back to the Otuses I would believe that eliminating axial chroma is one of the main reason they are so expensive, the other reason is excellent performance at full aperture. Personally, I am interested in using something like 85 mm for short DoF type of work and an 85 mm lens with excellent performance at full aperture with no axial chroma is quite interesting.
The S (type 007) is not around yet, so I guess that we have nothing definitive about image quality. A qualified guess may be that it will be close to the S (type 006), but offer higher ISO and larger DR. Personally, I would prefer smaller pixels, as I am shooting at 3.8 microns on Sony Alpha 77 and I find that resolution a better match for the lenses I use than the 6 microns on my Sony Alpha 99 or the 6.8 microns on my P45+.
I think that the Leica S is a very fine camera, if one can afford it. But full frame 135 has some awesome sensor and some very good lenses matching those sensors at a much lower price. On the other hand, if perfection is sought and cost doesn't matter nothing beats MFD technical cameras with lenses designed for digital.
Now, cameras like the Leica S, Pentax 645Z and the Hasselblads may be good compromises, and a good compromise is not a bad thing.
I would assume that both Nikon and Sony follow Canon's lead into 50 MP pretty soon. To me those 50MP cameras paired with the best optics seem to be pretty competitive with the smaller MFD formats.
Best regards
Erik
Hi Erik, you're right of course. I'll correct my post, was thinking of Otus lenses on the Sony FE mount (spent too much time over at the FM alternative forum )
I agree, especially the 70 mm can show some nasty axial chroma, especially wide open up to f5,6 in heavily back-lit tree branches and such. Luckily, most of it can be dealt with in Lr.
