Verdict

The Zeiss ZE Distagon T* 25mm f/2 is a impressive lens. It is capable of delivering an outstanding center resolution combined with very high contrast at all mainstream apertures. However, expect some corner softness at large aperture settings - that said it is probably not really an issue for most of the kind of images taken at f/2 or f/2.8. The Distagon is very sharp at f/5.6 and f/8 which is e.g. certainly appreciated by landscape photographers. The virtually non-existent CAs contribute to the high sharpness perception here. A moderate degree of barrel distortion is typical for such a wide-angle prime lens. A common Zeiss weakness is the amount of vignetting which is very obvious at fully open aperture.

Just like the rest of its family, the Zeiss lens is built to the highest standards except for the lack of weather sealing. Some users may complain about the lack of AF but this is, frankly, not really a show-stopper at this focal length. The focus confirmation is available in the viewfinder and in very critical scenes (for example close focus) Live-View can give you a helping hand.

A drawback is, of course, the steep pricing of the lens. At around 1400EUR it competes in the same price class like the Canon EF 24mm f/1.4 USM L II. The Canon lens is obviously faster but also a tad worse at comparable aperture settings. Your choice ...
