Sony A7r vs. Leica M9 Dynamic Range Compared

The Sony A7r camera body vs. Leica M9 camera body sensor dynamic range comparison in these two photos illustrates the advantage Sony has in its latest 24MP CMOS full-frame camera sensor (same as used in the Nikon D600/610).

The lights and darks in the Sony A7r photo contain color and definition of lines and texture.  They’re not just white and black.  Compare the Sony photo to the Leica M9 photo where the bright and dark areas are mostly just white and black without much visible definition of what is in those areas.  Colors are also more recognizable in the Sony A7r photo compared with the Leica M9.  Granted, the Sony A7r camera CMOS sensor is basically one year old, whereas the Leica M9 CMOS Sensor, released in 2009, is now 5 years old.  This type of dynamic range difference between Sony sensor and Leica sensor 4 years older, should be expected, regardless of manufacturer.  Chip technology will continue to advance whereas lens designs and materials are much more stable and only improve slowly over time.

Another thing to keep in mind is the Leica APO-Summicron-M 75/2 ASPH (aspherical) lens mounted on the Sony A7r is using an adapter mount and is not meant for the Sony EF mount.  There are few lenses available for the Sony A7 and Sony A7r for the moment, so there’s currently a rush to find out which lenses work well with this new full frame mirrorless camera.

Once Sony releases lenses that are meant for this brand new full-frame body, we should see some more comparable photo results vs. off-brand (Zeiss, Leica, Voigtlander, etc.) lenses.
