Sonnar T* FE 35mm F2.8 ZA
Great image quality in a small package
I am using the lens with my a7r. It provides very high image quality even wide open at f2.8, with optimum sharpness around f4 to f/5.6.
The lens does the 36mp camera justice unlike many lenses I tried on a 36mp DSLR (another maker) I used to have. My criteria is finely detailed landscapes being reviewed at 100% pixel-peeping on my 25" monitor.
The lens is excellent not just in sharpness but in overall tonal rendition (color and contrast). The bokeh is usually good, esp. at f/2.8. The lens provides a very pleasing overall effect - sharp but smooth and natural looking.
Being able to get this level of image quality in such a small lens is astounding to me. The build quality seems very good to me - metal plus high quality plastics (not all plastics are created equal).
Not only does the lens work well with autofocus but it is a pleasure to manually focus it as well. I can get exact focus very easily and consistently (which I cannot say of the experience I've had with even the best lenses, AF or manual only, on DSLRs).

Very fine lens
This is an excellent lens. It is light but in no way poorly constructed. Has quite a precision feel. The images with the A7r body are spot on: crisp, sharp, no distortion. Makes a delightful combination. AF is fine.

Build feels cheap
I received my 35mm f/2.8 today, I am rather disappointed in the build quality of this lens. It is VERY light.. which can be useful but also ..to me.. gives me a sense of plastic.. The lens uses a 49mm filter thread and I do beleive that the threads are indeed plastic.. For $800.00 I feel the lens could be better built...sorry Sony
