The colors from the H3DII-31 are rendered correctly at all ISO set-tings. The colors from the Canon and Nikon cameras show a clear color shift in several colors.

The image shot with the Nikon camera, shows some unnatural satura-tion whereas the H3DII image show the original colors of the scene.

The H3DII image has detail all over the image area and thanks to the auto-matic Digital Lens Correction in Phocus, there is no visible chromatic aberration or distor-tion in the image.

The Nikon image has clearly less detail and also show some heavy chro-matic aberration which cannot easily be corrected for as it is not symmetrical when the lens is shifted.

MTF diagram for Nikkor TS-24mm at f/3.5.(15, 30 60 lp/mm)

The photo on this page was shot with a state-of-the art 35 mm DSLR system

comprising a 21.1 megapixel body and a f1.2/50 mm lens at ISO 100.

The aperture stopped down to f2.0.

The rendition of low contrast detail in the corner of the image

is suffering from the general drop in contrast near the edge of

the image circle.

The easily visible red fringe running along the line of the shoulder proves

that contrast of fine detail is un-doubtedly compromised by lateral

chromatic aberration.

Sharpness isn’t just compromised near the edges of the image. The anti-aliasing filter in front of the sensor is placing an upper limit on the resolu-

tion of lens and sensor combined.

Lateral chromatic aberration is not an issue with the Hasselblad lens.

The advantage of a higher resolu-tion sensor continues to be visible even near the corners of the image,due to much better edge sharpness of the Hasselblad lens.

The high contrast of fine detail that the lens delivers can be fully exploited as there is no anti-aliasing filter limiting the resolution. Moiré artifacts are eliminated by the moiré tool in Phocus.

Extract from Victor 2008 Photokina Special article “...The bigger the better”

The photo on this page was shot with an H3DII-31 with an HC 80mm lens at ISO 100. The aperture was stopped down to f2.8 to obtain the same depth of field as the 35 mm DSLR systems.

Larger sensors and higher resolutionMedium-format CCD’s are more than twice as large as 35 mm sensors.

More well-defined depth of fieldDue to the larger sensor, a Medium Format camera produces a shorter depth of field at the same aperture, than a 35 mm DSLR. E.g. f/2,8 on a 36 × 48 mm format produces the same depth of field as f/2 on 24 × 36 mm format.

Larger and brighter viewfinder imageCompared to a 35 mm DSLR, the Hasselblad view-finder image is significantly larger and brighter.
