I'm looking for a good lens review website.
One site that I really like is DPReview (http://www.dpreview.com/lensreviews?sort=brand
), in particular their sharpness charts (example: http://www.dpreview.com/lensreviews/canon_100_2p8_is_usm_c16/4
). However, they have a very limited database, only 11 Canon lenses as of now.
I also like The Digital Picture (http://www.the-digital-picture.com/Reviews/Canon-Lens-Reviews.aspx
) and Ken Rockwell (http://www.kenrockwell.com/canon/lenses/
), but they tend to be more on the subjective side of reviews: not a lot of numbers and charts to compare across. Nothing wrong with that, but not exactly what I'm looking for.
) has a pretty extensive database, and although some of their reviews can be very controversial here, I have no reason to believe they are not doing a proper job. However, I find most of their charts using colors instead of lines and numbers difficult to compare objectively. Also, sometimes I don't understand their testing criteria.
For instance, the 85/1.8 vs. the 100/2 on the 5DIII: http://www.dxomark.com/index.php/Lenses/Compare-Camera-Lenses/Compare-lenses/%28lens1%29/241/%28brand%29/Canon/%28camera1%29/0/%28lens2%29/798/%28brand2%29/Canon/%28camera2%29/0
The 85 is sharper (15 vs 14), has better transmission (2 vs 2.2) and less aberration (3 vs 5). The 100 has slightly less distortion (0.3% vs 0.4%) and vignetting (1.4 vs 1.6). Pretty similar numbers, I'd say. Yet, the 100 has a score of 30 while the 85 gets only 26. And I don't understand why they always seem to say that all lenses are best wide open ("Best at f=100mm & f/2", "Best at f=85mm & f/1.8")
Another example, Sigma 18-35/1.8 vs. Sigma 35/1.4 on the 7D: http://www.dxomark.com/index.php/Lenses/Compare-Camera-Lenses/Compare-lenses/%28lens1%29/1141/%28lens2%29/1056/%28brand1%29/Sigma/%28camera1%29/0/%28brand2%29/Sigma/%28camera2%29/619
The 35 has better transmission (1.6 vs 1.8 ), distortion (0.2% vs 0.3%), vignetting (0.8 vs 1.1), and aberration (5 vs 7). The 18-35 is only slightly sharper (13 vs 12), yet the 18-35 has a score of 24 and the 35 only 22. I don't understand their numbers.
Also, highly regarded lenses, like the EF-S 10-22 or the 16-35/2.8L, have some relatively poor numbers on DxOMark.
My ideal site would be like DPReview with a database the size of DxOMark :-) What do you recommend?
