>>4118886No one has a comprehensive database for all lenses. They all vary somewhat in testing protocol too. I like LensTip for getting a rough idea of how sharpness changes through the aperture range (picrel), also has coma, vignetting, chromatic and spherical aberrations, bokeh shape too.
TheDigitalPicture and OpticalLimits also are decent and the former has a good comparison tool.
Don't put too much stock into the actual #'s they score, and don't be a total idiot like I see her often and compare test value #'s across different sensors.
Best bet for you own gear is doing you're own sample shots and seeing how small/large the difference is.
