Get Zeiss Batis at B&H Photo.
In my review of Zeiss Batis in Guide to Mirrorless I present examples and narrative of a wonderful June 4 snowstorm. These examples give an excellent idea of the performance envelope of the Zeiss Batis lenses.
Example images are all up to 24 megapixels in size (with intermediate sizes also). This is not a technical evaluation but a narrative and story primarily; the images speak for themselves in overall visual impact, and 24MP is well beyond ample resolution for evaluation purposes.
Some readers have inquired about Sony A7R shutter vibration. This is a concern that never goes away and in some cases there is subtle sharpness damage peaking around 1/125 second (all the images were shot as full aperture series). However, each image was selected for the total visual effect, e.g., its aperture which influences vignetting, DoF, streaking snow for a particular shutter speed. And that is the goal: how do the lenses perform in sharpness and rendering, e.g. what is the visual impact. And even at 24 megapixels the loss of sharpness is mitigated by the 2:3 downsampling.
