I have had my 60D for about two years with the lenses from my old EOS film cameras. Last year I splashed out on the Canon EF 70-200mm f/2.8 L IS Mark 2 II USM lens and a Tamron B005 SP AF 17-50mm f/2.8 XR Di-II VC LD Aspherical (IF). Neither of these lenses give me the sharpness I was hoping for, even shooting in RAW. I tried the old EOS lenses and the kit lens again, but all images are still not sharp enough. I have tried auto and manual focusing, but to no avail. Any suggestions would be appreciated.
