the Tamron lens was adjusted, would it have a severe front/back focus again? Would it need to go back to Tamron support to zero/reset it? Or would there not be any focus problems expected? If I were to buy say an M5 with the EF(-S) adapter from Canon. a Canon 35mm f/2 (non-IS) and Canon 70-200 f/4 L - both of which I bought used and that are fine on my 1000D, but I do not know if anything was ever adjusted on those. It had severe front/back focusing issues. I'm asking because I had major trouble with multiple iterations of adjustments for my Tamron 17-50 VC f/2.8 on my EOS 1000D some years ago - as far as I understood it back then from Tamron Support the lens had to be adjusted a *lot* to my 1000D body. So far so good - but what does that mean if I were to use a EF(-S) lens using an adapter on e.g.
Canon micro focus adjustment series#
Some mirrorless Sony Alpha series cameras appear to have an option for AFMA for A-mount (read: DSLR lenses), but not for E-mount (read: mirrorless) lenses. do not have an option in the menu for this, not even Canon's top of the range M5. Hence, most mirrorless cameras including Canon, Nikon. This is a more generic question: I read that mirrorless cameras do not require AF microadjustment (AFMA) anymore, since AFMA is used to calibrate the focus offset between APS(-C) sensor and actual AF sensor (typically phase detection) in a DSLR body, and on mirrorless cameras focusing is done using the one and the same main sensor (using contrast detection).
