I've gone through and tried af fine tuning. Tried turning it off. Etc. Here's my issue with my 5d Mark iii camera that I want so desperately to love. Maybe I have a dud? I dunno? I will put the camera on a tripod, point it at a brick wall and focus and shoot, and sometimes it will nail it, and sometimes it will be dreadfully soft. I'm using the center point. I've tried all different focusing modes, and I'm shooting a very contrasty (should be easy to focus on) brick wall. Again, it's about 50/50. Sometimes it nails it. Other times it locks on very fast, which is great. I take the shot, zoom in and see how ugly soft the image is.Sounds exactly like the problem I had, I took it back and i'm waiting on a replacement
The reason I'm even doing these test is I've taken it on two engagement shoots so far. And have seen this issue. There will be times when it will lock SOLID on exactly what I'm trying to focus on, I'll take the shot and it's awfully soft. Other times it was doing great. So I was thinking it was user error until I set up these very controlled tests shooting at a brick wall. I'm shooting with nice L lenses as well. Any help? What would you do? Would you send it in? Would you return and just get a new one?
going back to using my 5dmk2 I NEVER ever thought I would say this but ah my nice reliable 5Dmk2 center point
just nails it every time.
Take it back see if you can get a new one. most people dont seem to have this problem (I think JR also had this problem on his too) but overall most people are reporting accurate focusing so I think is likely a bad unit
