I expect it's prices to start climbing once A7R owners realize how good it is.Another vote for Contax G 90. Ridiculously good value for money.
I am not having any issues focusing mine.Isn't the MF damping less than ideal on the Contax G90?
I have both a Zeiss Contax G 90mm F2.8 and a Leica M 90mm F2. The former is way lighter and tack sharp. From what i have read, there is an adapter allowing AF for the Contax G lenses : these lenses were made for AF and you are right, they are not as nice to focus manually (but on my E-M5 i still prefer to use them over the M lenses i have, which are too heavy).Isn't the MF damping less than ideal on the Contax G90? Optically, all the reviews I have read say great things. Only 90 I have us the Leica 99/2 apo, and I could not be more pleased. Got a mint copy off the Bay for a good price....
+1My biggest pleasure - so far - with the a7r has been the 135 Apo-Telyt M. I found it difficult to use with the M9. It was hard to frame and focus accurately, even with the viewfinder magnifier.
On the a7r it's an absolute gem. Easy to focus, crisp right across the frame. I'm now seeing what an extraordinarily sharp lens it is, even wide open. I'm having to put Bandaids on my eyeballs.
Wanted to report on the Zeiss 135 F2 Nikon mount. I know this lens is big and heavy . Certainly not as travel friendly as I would like myself. But I need this lens at least for a lot of client work and need the F2 speed. Now when in Yosemite I rigged up Jacks Sigma 1.4 converter to it and have to say I was floored that even at F4 there was simply no loss of quality at ALL. It became a 180 f 2.8 laser beam. I have a Kenko that I did not even try yet but I'm ordering the Sigma 1.4 almost immediately. You need the length I could not recommend this enough. Yea big, heavy and a solid brick but the focus throw on it I found much better on it over the Leica 135 3.4 which I would not use on people with that lens the focus throw is very short and hard to nail a human face over the Zeiss which is far easier. Obviously this depends on what your shooting but landscape only type work the Leica is very good but people and tough focusing requirements the Zeiss is better at it.just thought I would pass that on. If I had the money I might even consider the Leica just for travel.
Haven't seen any darkening, smearing or color casts in the corners with mine at any aperture. Here's an example. Just a test shot, hand-held, done a couple of days ago. EXIF shown in border:I tried a leica 135mm M Apo f3.4 today. There is darkening in the extreme 4 corners that does not get better or worse with aperture. I am wondering if others have seen with this lens.
Try changing the adapter. I've read on this list that some adapters used on the Nex5-6-7 may not be compatible with the A7s and could create problems of this kind : their smallest opening diameter is large enough for APSC sensor, but not for a FF. The fact that changing aperture does nothing to improve the corners seems to point in that direction too.I tried a leica 135mm M Apo f3.4 today.
