>>4081919No site has like every lens.
LensTip (my fav) has resolution charts like picrel.
OpticalLimits has similar and gives more granular numbers for their measured sharpness.
TheDigitalPicture has a tool for mouse over comparisons of separate lenses.
They should also give insight to a lenses vignette, aberrations, bokeh shape, etc.
Important to note, and they all give disclaimers on this, but you have to be very careful if you're using the charts / figures to compare across different lenses, especially across different brands.
