So i tried it again.
I moved the target to the living room with the big bay window with lots of natural light coming in. I did single shot and burst in AI servo and AF was pretty much on for 21 shots between the 2 modes.
I moved it back down to the game room with window closed and only lights on. I have all LED bulbs and out of 9 shots it only got focus on 4 the rest where OOF. its lower light down here as well. So not sure if its the lower light or the type of light LED messing with its AF. but like I said my 85 1.8, 70-200, and 24-105 all had perfect focus in game room with LED lights
I had the same problems shooting in my office at home. All the lighting is soft white fluorescent bulbs. The only thing consistent about my copy is that it consistently misses AF at a variety of wider apertures and at various distances. The consistency improves as I stop down, but isn't truly consistent until f/5.6!
