Test of the new Zeiss Vario-Tessar FE 4/24-79 ZA OSS on the Sony A7R
This is no professional test and was planed for my own judgment of the lens. After looking at these images I hope, that we soon will get profiles included in the next Adobe Camera Raw!
autofocus, tripod, horizontal control with bubble level, IR remote control
LR 5.3 default development, export JPG 92%, sharpening for screen during export
OOC JPEG images with camera defaults (I never use JPEG out of the camera and did not adjust any settings)
focal lengths 24, 50 and 70mm, with f/4, f/5.6 and f/8
I found severe distortions in all focal lengths and apertures in the RAW files. These distortions seem to be very good corrected in the camera JPEG with the effect, that you loose parts of the 100% image!
I added the OOC images with f/4 for these three focal lengths. EXIF is included in all images.
You find all test images in full resolution on my flickr album (Click here)
together with a set of the OSS test images, of course a complete individual result!
as example 50mm at f/4 from RAW
and OOC JPEG
P.S.: The new Zeiss 24-70mm is in Stock in USA at Amazon, Adorama, BHphoto, SonystoreUS, and in Europe at Sony DE, FR, IT, ES, NL, BE, SE, PT (Click on country name to see the lens site).
