next PZ lens test report: Zeiss Biogon T* 28mm f/2.8 ZM (on Sony NEX) - Klaus - 08-04-2011 It doesn't like the sensor it seems: [url="http://www.opticallimits.com/sony-alpha-aps-c-lens-tests/663-zeisszm28f28nex"]http://www.opticallimits.com/sony-alpha-aps-c-lens-tests/663-zeisszm28f28nex[/url] next PZ lens test report: Zeiss Biogon T* 28mm f/2.8 ZM (on Sony NEX) - Brightcolours - 08-04-2011 In general I think you should post more sample images (or more often), but especially with a lens like this, images would be welcome (especially in regards to the reddish corners you mention).. next PZ lens test report: Zeiss Biogon T* 28mm f/2.8 ZM (on Sony NEX) - Klaus - 08-04-2011 I'm trying to provide sample images for mainstream lenses but frankly I don't really want to spend extra efforts on exotics unless they're something special. next PZ lens test report: Zeiss Biogon T* 28mm f/2.8 ZM (on Sony NEX) - WyldRage - 08-04-2011 Well, they would be useful to check if the measured vignetting might be linked to colour shift issues. I'm using a Voigtlander Ultron 28mm f2, and while the major issue is the vignetting, but there's also a light colour shift in the corners. By the way, Sony seems to have improved their sensor performance with wide-angle rangefinder lenses on the Sony NEX-C3, according to this post: http://www.fredmiranda.com/forum/topic/1030741/1#9793822 It seems to have helped somewhat with the native E16mm lens, as seen here: http://www.photoclubalpha.com/forum/viewtopic.php?p=58527#p58527 I can't wait to see if the NEX-7 will also continue on this path. next PZ lens test report: Zeiss Biogon T* 28mm f/2.8 ZM (on Sony NEX) - Klaus - 08-04-2011 [quote name='WyldRage' timestamp='1312465034' post='10391'] Well, they would be useful to check if the measured vignetting might be linked to colour shift issues.

[/quote] The color shift issue is there but it's nowhere as extreme as with the Voigtlander 12mm f/5.6 (of course). I've taken a few field image where you can spot traces. |
