Originally posted by Jantus One can see that as quite bad... But on the opposite, except when testing the gear, one is likely to finally publish the photo in a compressed format (like JPEG) and to post process it too to get the colors, framing and other things he want (or at least let the jpeg engine do it).
I routinely see the effect of post processing on my photos. Even the best lenses out there provide so-so photos in many conditions and post processing often transform them in real nice photos.
While I agree we should test the lense, in isolation, what really count is the final result. To me there would be more sense to compare lenses once post processed to see how they really contribute to the final product. In many case screens on review from highend lense look worse that what an entry level lens provide... They keep on purpose all the optical problems that all Jpeg engine, lightroom or DxO now remove automatically. They also never push the color or exposure or reframing... Providing in the end so-so photos from the best lenses.
For me it is the final result that count... and one should prove a more expensive lense can do provide a better final result. Not just emphatise issues that are now automatically corrected by most tools.
