[QUOTE="Vincent, post: 203646, member: 15675"] So some evolution. 1) After my test I forgot to change the setting and it ended up in -20 iso the +20 I thought was good. I was at a Christening, took quite some shots and they turned out OK. 2) I figured out the AF[COLOR=#333333][COLOR=#333333] Fine Tune: -- issue, it seems that going into lifeview puts my focus in AF-F. It seems very few people even know about this mode. However it seems to focus greatly. 3) One test was fully unsharp, checking again brought me to see the focus point was not where I thought it was (not central, but moved all to the right). 4) I did a different test showing how small the issue is (if any): This is a lot of crop on a cup: Manual you see the imperfections.
