Which One? Battle of the Leica 50mm Summicron Lenses

by Chris Gampat on 09/06/2011

With both the Leica 50mm f2 Summicron collapsible and newer version of the Leica 50mm Summicron on me, I decided to do a head to head test with the Ricoh GXR and A12 module to see if one really needs to get the latest and the greatest lenses for the best image quality and sharpness.

Let’s see if your pixel peeping skills are up to the challenge.

Conditions

Both lenses were mounted on the Ricoh GXR and A12 module and focused the same distance away. The camera’s setting were set to ISO 500 and was set to aperture priority with a two second shutter delay. I fired a shot at each aperture on the lens and then repeated the test with the next lens.

All lighting conditions were the same. The camera was mounted on the Vanguard Nivelo.

After shooting in DNG, the images were sized down to 500K at the most with no vertical or horizontal resizing. I also keyworded and converted them to JPEGs.

Purpose

Once again, the purpose of this test is to see whether or not one can tell the difference between the old Leica lens and the new one if they are considering investing in the GXR system.
