Fine tuning auto focus

[Dan_uk_mids]

I did this with a couple of lenses a while ago, but had since updated the firmware on my camera. This morning I spent some time fine tuning the auto focus on all my lenses. It is a bit of a fiddle and definitely requires some patience. I think tethering made it way easier that it otherwise would have been. I think its a well worthwhile exercise. I was particularly impressed by the results I got with my Sigma 105mm Macro after fine tuning. I've put a few test shots below. A bit surprising some of the lenses needed quite a lot of adjustment. Yet some of my cheaper lenses were almost spot on before any adjustment.
