If you're plunking down tens of thousands of dollars for a medium-format digital camera such as the Hasselblad H3DII, Leaf Aptus 75s, Mamiya ZD or Phase One P45+, you would expect the best image quality. DxO has been busy testing these cameras and today they published the results on DxOMark.com. The results were surprising.

"It took our dxomark.com testing team some time to double-check our findings, as we were very surprised when we saw the initial results," comments Nicholas Touchard, VP Marketing, Image Quality Evaluation, DxO Labs. "We had anticipated that such high-end, high-resolution, medium-format cameras would outperform all DLSRs by far, but such was not the case."

"We were astonished to see that high-end DSLRs outperformed the medium-format cameras for Dynamic Range and came in on par for Color Depth," Touchard adds. In fact, while they performed extremely well in specific areas such as digital noise and tonal range, the best-performing of the four tested medium-format digital cameras was ranked behind six full-frame DSLRs on DxOMark's objective Sensor scale--an overall rating--and one of them is ranked 24th, in the middle of the APS-sized sensor DSLRs.

DxOMark has posted 61 digital camera sensor tests to date, for cameras ranging from high-end compact cameras to medium-format studio cameras. “Adding our measurements on this first set of medium-format cameras to our database demonstrates our commitment to our goal of building the most comprehensive database of RAW image information available,” notes Touchard. “We want to give professionals and expert amateur photographers the highest level of RAW image data possible."

A detailed analysis of the test results will be coming soon from Adorama's AIRC, which is an Expert Partner site with DxOMark.
