ZEISS Touit 2.8/12 and Touit 1.8/32 Sony mount lens reviews: performance at a price

ZEISS Touit 2.8/12 Sony E mounted on Sony NEX-7 Versus Olympus M. Zuiko Digital ED 12mm f2.0 mounted on Panasonic GH2
When the second lens in the series, the ultra-wide Distagon 2.8/12 (18mm equivalent), is compared against the faster yet not as wide Olympus M.Zuiko Digtial ED 12mm f/2.0 (24mm equivalent) the ZEISS lens fares quite well. While it’s not as sharp as the Olympus or its 1.8/32 sibling, with such an extreme angle of view it’s not likely to be. What’s more, it has excellent light transmission and very low distortion and vignetting. The only downside is noticeable Chromatic Aberration when paired with the NEX-7.

Are you testing distortion correction...... algorithm?

I believe you have made a mistake.
0.6% distortion of Touit 32/1.8 is camera firmware corrected result.
You can refer to
Without distortion correction, the distortion is much higher (-1.8%)
How can you compare lens performance without disabling these correction first?
When mounting on different mounts (e.g. X-Pro1), the measured value will be different due to different algorithm.
I'm not to say Touit 32/1.8 is a bad lens.
I own one. Its image quality is really fantastic (great details, vibrant colors, typical Zeiss pop)!

The NEX-7 is known to have degraded resolution towards the edges. Even native NEX lenses can produce higher resolution at the edges on the 14MP NEX-5 than the 24MP NEX-7. I wouldn't take these results as the last word on the Touit lenses' performance.

Re: Touit lenses
+1. Sigma 19mm and 30mm lens are absolutely amazing for still photos. I just you could use them for video too - the vibrations that the lens produce while refocusing are just too distracting. For the price though both of these lens are no brainers.
