Roger from Lensrentals (Click here) tested the new Zeiss Touit lens and compared it with the cheaper Sony 35mm f/1.8 lens. It is certainly not a surprise to see the Zeiss being the winner of the contest but the Sony performance is quite close! He writes:
The Sony 35mm OSS gives you slightly better performance optically, a wider aperture, and image stabilization for $449. At f/1.8 it’s pretty equal to the Touit in resolution and has less distortion. Stopped down just a bit, to f/2.2, though, the Touit gives much better optical performance than any of the other lenses. Worth $900? To some people certainly. To others, not at all. For me, taking actual pictures with it confirmed what the numbers suggested. The center resolution is probably the best I’ve seen from any lens on an NEX camera. That’s enough to make it a future purchase for me.
Roger also writes that the Sigma 30mm f/2.8 is the best bargain. But of course it’s maximum aperture is f/2.8 “Only”. If you need a faster lens the Sony my be the best bet. But if you want to have the ultimate image quality you better go for the Zeiss. In short…it’s up to you
