Shortly after the Canon 5D Mark III and the Nikon D800 were released last year, DxO Labs published the results of the sensor performance of both cameras. The initial tests showed much better results for the D800′s sensor than the 5D Mark III.
Now, the DxO team is singing a different song after further comparisons between the cameras using high quality lenses.
Mounting a high quality lens makes all the difference. From our database, the resulting P-Mpix scores from various body/lens combinations reveals the D800 and Canon EOS 5D Mark III may be closer in resolving detail than expected.
When comparing the huge volume of data accumulated over measuring 147 lenses, one very surprising result was revealed. The average sharpness scores of the Canon EOS 5D Mark III matched the Nikon D800 and if the results were based solely on the mean average, the Canon actually out-performed the Nikon.
Either way, the Nikon D800 sensor simply isn’t as adept at resolving detail, pixel-by-pixel, as the Canon EOS 5D Mark III. There’s another surprise as well.
