I encountered focusing problems with my 70d purchased a month ago, inconsistent focusing in low light (incandescent lighting) from f4 to a narrower apperture. With my eagerness to find a solution I made some adjustment on the MFA and didnt give me good results yet until I dug on the menu and found the settings on the lens drive (C.Fn II: Autofocus/ Lens drive when AF impossible). At default, it is set to continue focus search, and I made it STOP FOCUS SEARCH. I took some snap shots inside our room and it improved a lot on sharpness and low light performance...
My question is, do you think I got the right solution? Or am I having the wrong impression onthis issue? I know I can be able to answer that on my own but I still need your point of view on it... tnx
