M.Chapman Posted May 10, 2013 Share Posted May 10, 2013 I've got the following equipment 2 x Canon 550D SLR bodies and Canon 15-85 EF-S, 10-22 EF-S, 55-250 EF-S and 60mm EF-S lenses. My dilemma is that I find that phase detect focussing is just not reliable enough, and so I tend to use Live View contrast AF which is always spot on, but slow and tedious. I've done some limited tests and it's clear that there's a little bit of front focussing going on with the phase detect AF suggesting that my lenses and/or camera may benefit from calibration or AF micro-adjust. Note that the errors are pretty small. If I use phase detect it's fine for 6x4". But at 100%, I can't be confident of reliably meeting Alamy's requirements. So I appear to have a choice. Send (both?) bodies and (all?) lenses off for calibration (any idea how much this might cost and who provides the best service?) Upgrade to a body with AF micro-adjust feature (e.g. Canon 50D) and make the fine tweaks myself. Unfortunately the 50D is bigger and heavier than I would like. Swap DSLR systems to perhaps a Nikon (D7000) which is not too much larger and has AF micro-adjust. Could be expensive with having to change lenses Wait for Canon to add AF micro-adjust onto a smaller SLR .... 750D? Any thoughts or advice appreciated.
