This is breakthrough News for the Pentax K-5! One of the downfalls with Pentax in the past when compared to their Nikon and Canon counter parts was the snobbery about their AF being superior to the Pentax, thanks to ColorFoto we have evidence this is no longer the case.
They performed about 1300 measurements with 57 lenses on nine cameras.
10 shots using AF were taken in wide/standard/tele position with each lens.
Another picture using manual focus with optimal resolution is the reference.
The ratio of the resolutions of the pictures then serves as a measure.
Lenses used on the cameras:
Canon 70-200/2.8 (-)
Sigma 18-250/3.5-6.3 (-)
Tokina 12-24/4 (-)
Nikon D 7000
Pentax 55/1.4 (The Pentax performs better/more consistent than the Sigma)
Sony 70-200/2.8 (-)
