Further readings for the Carl Zeiss Planar Touit 1.8/32 Sony E
To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
Continuing our series of lens recommendations for new camera models, we’ve had the opportunity to assess the new entry-level Sony A3000 - the first of a new DSLR form-factor from the firm to adopt the mirrorless E-mount. We’ve assessed and collated data on a sizeable collection of Sony and third-party prime and zoom models to assess image quality. Read onto find out which of these models perform best when paired with the new camera.
Sigma’s range of DN A lenses have been designed for mirrorless cameras using both MFT and APS-C sensors, albeit with different mounts. As the equivalent to a 45mm on an APS-C camera we’ve tested the 30mm f2.8 on the discerning Sony NEX-7. Read on to find out how well it performs.
Introduced during 2011, the 24-Mpix Sony NEX-7 remains a high-watermark for mirrorless models despite recent introductions from rivals. We’ve now had the opportunity to measure the performance of this camera with a number of promising new lens models. Read on to see how well the combination of Sony’s high-resolution APS-C sensor and the very latest E-mount lenses perform.
ZEISS already have one prime lens in Sony’s NEX line-up, albeit made under license for them, but at Photokina in September, the optics firm announced its intention to produce AF lenses in both Sony NEX and Fuji X mounts. The first of these lenses in the series, dubbed Touit by the maker, are an ultra-wide Distagon 2.8/12 (18mm equivalent) and a standard-type Planar 1.8/32 (50mm equivalent). Read on to see how well these two new lenses perform on the Sony 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 http://www.lenstip.com/386.6-Lens_review-Carl_Zeiss_Touit_32_mm_f_1.8_Distortion.html
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.
+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.
