Zeiss Planar T* 50mm f/2 ZM on Sony NEX - Review / Test Report - Sample Images & Verdict
Lens Reviews - Sony Alpha/NEX (APS-C)

Sample Images

Here're some RAW-converted images taken with the NEX-5. Please note that there's no valid EXIF data due to the lack of electronic coupling. Most images were either taken at f/2 or f/8 so you may roughly conclude the aperture settings from the depth-of-field.

Verdict

The Zeiss Planar T* 50mm f/2 ZM may be an exotic choice for Sony NEX users but it's certainly a highly interesting one. The lens shows no major weaknesses but there's still room for improvement. The center resolution is on a very high level at large aperture settings and the borders are pretty good here. The sweet spot is reached somewhere around f/5.6 with a very sharp results across the image frame. Lateral CAs are well controlled and not overly relevant. Distortions are basically absent. There's a tiny bit of light fall-off at f/2 but it's really nothing to worry about on the Sony NEX. The quality of the bokeh is generally fine although we've seen lenses producing a more buttery background at max. aperture actually.

The build quality is just stellar thanks to an all-metal body and super-smooth controls. In a world of plastic lenses this rocks! As mentioned the Zeiss lens is actually designed for the Leica M mount (and Zeiss Ikon) so you've to live with an adapter solution and as such without AF. However, thanks to the EVIL design of Sony NEX cameras (magnified focus view, LiveView) this is less of an issue compared to adapter solutions on DSLRs. However, make sure that you can live with this manual workflow prior to rushing out and go for it.
