Originally posted by repaap just as you two slready had conversation about it. it could be usefull to use catch focus, but it don’t work in all circumstances..but it helps. I’m also drooling over FA*85...and many other lenses, but meanwhile my FA 77 will do. bokeh is not as nice as with 85, and also that little a bit more tighter Fov gives nice result for portraits. still FA 77 is not slouch.
CIF has the same issue that the Focus Confirmation has, that is it fires as SOON as you get the focus confirmation, which for some DoF is just too soon. That is if I understand all this correctly. This pic might better explain what I mean;
So CIF might be useful if the stop down is sufficient, but wide open I have my reservations slightly. Also the speed of which you turn the focus ring might also factor in, a bit faster of a rotation might mean it fires a little later, resulting in a sharper image perhaps than rotating super slow...
