Next PZ lens test report: Sigma AF 8-16mm f/4.5-5.6 DC HSM (Nikon DX)

The point is that we don't know the sample variations. We don't reach statistically relevant dimensions. As such it is not possible to withdraw a thumbs up just because of decentered samples. The Canon 24-70 or Zeiss 24-70 are also suckers in terms of QC. Does this mean that Canon and Sony lenses are bad in general ?



If QC was a number one priority we would all shoot Olympus Digital Zuiko ... (4/3, not MFT) ... IMHO.

Hi Klaus,



Thanks for the reply. I hope my original posting made it clear that I completely appreciate the problem you are raising and that I did not ask you to reach statistical relevant dimensions. I wanted to highlight an unease I carry for some time, but have little idea how to resolve. Perhaps averaging all the "rejects" per brand for a year might carry some mileage, but I am not sure.



By the way my DSLR is Olympus <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Wink' />
