Paul Mayall Posted May 23, 2016 Share Posted May 23, 2016 Hi everybody, over the past few weeks i have been calibrating various lenses on my Canon 7D mk ii, it dose not matter what i do it seems impossible to get tack sharp images more so with long 600mm lenses, the worst results come from the Canon 600mm and the sigma 150-600 sports, all of the lenses are tack sharp on my full frame 1Ds iii. Is their anyone here who can say for sure if the full frame sensor is sharper than crop, i am reluctant to send the 7d in for testing as there might be nothing wrong with it. Any knowledgeable people who can help will be appreciated. Thank's to all, Paul. Link to comment Share on other sites More sharing options...
