That is the big question. I've seen good reports of the ZM 25/2.8, but I haven't used it myself. The new Zeiss wide-angle coming out for NEX is rumored to be a 24mm f1.7, so it may be worth the wait.
p.s. the NEX sensor is a little bigger than Canon's APS-C sensor, so its crop factor is actually 1.5x
One should assume that a Zeiss 24mm f1.7 designed for the NEX is a compact one ?
With such a large aperture i am afraid we get a similar ZM 25/2.8 one...which is too big for my purposes.
What about the Zeiss Biogon 21mm F/2.8 Contax G?
Or better yet the Zeiss Biogon 28/2,8 Contax G , that is small !! I could live with a 42mm equivalent...
I have read some posts at dprevirew from a guy that claims he successfully adapted the 21mm Biogon f2.8 Contax G to the NEX. He had to cut some of the mount, didn't specify how. However the lens exhibited color shift and mudge in the corners.
KL,
Your C/Y 28 f2.8 needs corner correction ? Or are the pictures straight OOC?
How is the sharpness compared to a Canon mount for instance?
contax g 21mm can be mounted via metabones and kipon adapters - you have to cut off couple mm from the rear plastic shields. 28mm works fine. wide open has some color shift in corners, which goes away when closed down.
Very nice pictures in this thread - give an idea what is possible with the little NEX cameras.
I wanted to ask how you process the files. Coming from that ancient 1Ds I am surprised to see that raw files processed with the Sony software do not seem that sharp, at least not the ones from the CV 15/4.5 and ZM35/2. Portraits shot with the CV 90/3.5 look better. Still I was wondering if you sharped the files in post, since I never sharpened the 1Ds files I got from the 28 and 100 2.0 Zeisses. Is this something that has to be done with the high density sensors of today ?
Another thing I have to practice more is focusing the wides on infinity - does not seem to be that easy, I only got one picture right with the 15mm so far.
If sharpness is your goal, I would avoid Sony IDC. If you don't want to spend money on the popular converters, try the free Raw Therapee or Raw Photo Processor, both of which give outstanding output.
A member on getdpi, claims with the newest kipon adapter, that the contax g biogon 21mm fits without trimming, i will be getting mine hopefully next week to try

Unless that new Kipon adapter moves the lens back away from camera body (and affecting infinity focus), it's not going to work. Here is a picture of my G 21mm Biogon on a NEX adapter. You can clearly see that the plastic shields extend past the the end of the adapter. http://www.boncratious.com/images/G21mm&NEXadapter.jpg I tried to fit it to my NEX-5. These shields hit the built up flat areas to the top and bottom of the sensor (I know this becuase they left marks there as I tried to mount the lens). For it to fit, you clearly need to trim these shields. The adapter, if the proper lens registration distance is used, has nothing to do with with this. The adapter is not prohibiting the use of the lens.
thanks for the pic, and explanation, thats too bad, i'm going to pm him and see why he said that
