Leica M 35mm Summicron Lens Autofocus via Contax G Adapter

MxCamera posted their video of a Leica 35mm f/2 Summicron lens from 1960 on the Sony NEX-6 from 2012. The 52 year gap is bridged by a Contax G 28mm lens housing which has been modified to allow autofocus on NEX cameras. If only Dr. Mandler can see what his Summicron can do now.

Thanks MXcamera HK!

Contax G to Sony NEX Autofocus Adapter

DEO Techart Contax G to E-mount AF Adapter by MX Camera.

Contax G rangefinder fans take a seat. Your autofocus lenses have been brought back to life with an upcoming Sony NEX E-mount autofocus adapter. The video above from MX Camera shows the NEX-7 controlling the Contax G 45mm f/2 lens in autofocus mode. We hope to discover more about this adapter soon. We'll have to wait two weeks.

We have the manual focus adapter for Contax G lenses and we love the images that come from the lenses by Carl Zeiss.

NEX-5N and Wide Angle Lenses Gallery

Carl S. was generous enough to share his gallery of adapted lenses on the Sony NEX-5N. The lenses used were mostly Voigtlander lenses in Leica M mount. There are also Contax G lenses and a Canon 24mm Tilt Shift Lens.

Check out the Carl's NEX gallery which covers lenses from 15mm to 90mm focal lengths on the NEX-5N shooting the same scene. Make sure to look at the high resolution samples.

Sony NEX-C3 vs NEX-5 Red Shift Battle

Sony NEX-C3 vs NEX-5 Sample 1

bigpen from xitek forums was lucky enough to have the new NEX-C3 and the NEX-5 for a red shift battle. The red shift, vignetting, and / or discoloration is caused by wide angle rangefinder lenses (28mm or less) on the NEX. The light rays from the wide angle lens hit the edges of the NEX sensor at extreme angles since the lens' rear element is so close to the NEX sensor.

The comparison was done with a lens adapter and the Contax G 21mm Rangefinder lens, which is known to produce the red shift on the NEX-5 and NEX-3. It looks like the Sony engineers know of the red shift and has addressed the issue with the new NEX-C3. The 16.2 mp sensor of the NEX-C3 seems to handle the light from problematic lenses in a different way - better. The NEX-C3 samples are the ones on top in each set.

But don't worry, the red shift, vignetting, and / or discoloration can be fixed in post processing by using CornerFix.

The same issue exists for the Leica M8 and M9 and various wide angle lenses. The Kodak sensor in the M9 incorporates micro lenses to deal with the extreme light ray angles.
