Since I did not get my Andy Lesniak (aka. Wicked Circuits) dumb Canon mount to work properly (see previous lens mount test), and Birger Engineering is offering their Canon mount in a dumb version, I have now ordered one of those. Shipped today, and should be with me next week. Am very much looking forward to testing out thier mount. Watch this space for more info.

Yesterday the Andy Lesniak Canon mount for our RED One camera arrived. After struggling a bit with the back-focus adjustment, the mount is now installed, and I ran a quick lens breathing test. These were not lit or framed at all, just a speedy test on how the lenses perform under focussing. No follow focus yet either, thus not the cleanest pulls ever. No CC either.

All tests were done with the lenses set at their widest, also to test the focus at infinity.

Focus at infinity is not quite there. This might be because of the Contax/Canon adapter used. A new one is on order. If the lens is stepped down to 5.6, infinity is fine. Stepping down on the 25/2.8

Carl Zeiss Tessar 45mm/2.8 (Click to see the test at 1024×512) This lens is small, not thicker than a thumb.

Carl Zeiss Planar 50mm/1.4 (Click to see the test at 1024×512) The flickering comes from the office fixtures.

Carl Zeiss Planar 80mm/1.4 (Click to see the test at 1024×512) This is one beauty of a lens.

Carl Zeiss Tele-Tessar 200mm/3.5 (Click to see the test at 1024×512)

Tamron 500mm/8 (Click to see the test at 1024×512) This is just a lens I happend to have, and it was fun trying it as well. It has a fixed aperture of 8, and includes a macro function. Mirror lens, meaning it is relatively compact.

Generally I am happy with the performance of these lenses, their breathing is acceptable to me. The built quality of the Zeiss lenses is phenomenal, they have a very long focus throw.
