I found a good deal on a used 5D3 recently, and I was hoping that it would give me better focusing abilities in low light at wide apertures than my 6D. If nothing else, it's got a lot more cross points, which helps because trying to focus and re-compose when taking photos of fast action (music performances) at wide apertures (1.4) does not work well. The person I've focused on has already moved out of the depth of field if I focus and re-compose at 1.4. (For reference, I'm using a sigma 50mm 1.4 art lens. And stopping down past 1.4 isn't really an option due to the lack of light.)
I'm using one shot focus because, even though it's fast action, at least with the 6D, AI servo was always just a little too slow to keep up with people moving around to nail the focus at 1.4. It was just always hunting around and too slow to really keep up with what was going on.
Anyway, trying the 5D3 has, surprisingly, not even given me as good results as the 6D did. The 5D seems a lot more trigger happy and releases the shutter a lot faster than the 6D did, but it seems to prioritize taking the photo over actually getting the focus right. And, before anyone suggests this, I've already got the one shot AF priority set to focus priority. This makes it even more surprising that the 5D3 seems to blow the focus so much more than the 6D did. The 6D frustrated me at times because it struggled to achieve focus and release the shutter, but at least when it did get focus and take the photo, it was really in focus.
Does anyone else have any experience with autofocus performance between the two cameras? Should I give AI servo another try with the 5D3 since it's probably better at it than the 6D? Am I completely off my rocker for thinking that the 6D AF performance in these conditions is actually better than the 5D? I'm really dismayed because I thought the 5D would be the be all end all as far as autofocus goes, but after using it once, I find myself more drawn towards the way the 6D behaved.
