I decided that I would do a Autofocus Microadjustment on my 70D for my Sigma 150 – 500. I was happy with how the lens and camera focused but was finding I had many shots that were sharper just to the front of the subject, and after talking to a photographer this past weekend in Glacier figured that I would give it a shot (pun intended). So I did a test shot without the adjustment and a shot after I adjusted it and was happy to see that it was now a lot sharper on the subject. I really don’t think that it is the lens as much as the way that I shoot so now I have the focus dialed in more for me.
Am I going to do all my lenses? I am not sure. I shoot differently with all my lenses so to do them all may cause me issues. For now I am going to watch and see. I may do my 70 – 200L series as I use that one a lot like the Sigma but I will have to prove to myself that it is working.
Do I recommend this for everyone? NO!!! (Note: many cameras can only do this if sent to the manufacturer and I would not do this unless I had a lens that was giving me issues) If you can do this yourself on your camera first do some tripod tests using a tripod, then make the decision but only after a lot of tests.
