Carl Zeiss 35 ZM Biogon
Leica 35 Summicron ASPH
Leica 35 Summilux ASPH II
- Leica M9
- Paul C. Buff Einstein 640 with CyberCommander + PocketWizards
- Gitzo 3-series carbon-fiber tripod + Arca-Swiss Z1 ballhead
- Sekonic L-358 Light Meter
Setup + Processing
- Exposure was manually set using a Sekonic light meter
- The subjects were lighted using a Paul C. Buff Einsten 640 with a large octabox on a white seamless paper background
- White Balance is set to 5000K during the shoot and then manually set in RAW conversion using the white balance dropper tool in Lightroom
- The full resolution images were converted from RAW to JPG (Image Quality Set to 75 in sRGB color space) using Lightrom 4 with no post-processing other than the white balance correction.
- The focus was set on the yellow penguin’s eyes which is around 0.9 meters from the camera sensor with the camera on the tripod
- The images were shot at the following apertures: 2.0, 2.8, 4.0, 5.6, 8.0, 11.0, 16.0
The pink Puffle was deliberately placed further back to evaluate the out-of-focus properties of the image produced by the lenses. DVD cases were placed at the edges to help evaluate edge sharpness.

Center at f2.o
This 100% crop is probably going to make a lot of Leica lens owners cringe. The Biogon is clearly sharper than the Summicron ASPH (the Biogon is producing more aliasing in the penguin’s brown coat). Furthermore, it’s really hard to tell which one is sharper between the Biogon and the Summilux even at 100% pixel peeping mode. Ouch.
Once again, these photos are unretouched and without any sharpening whatsoever.
