I completely agree : +6 or 7 seems a lot ... that's why I write this post.


What's more, considering I own a 5D II and a 7D, with L lenses, which is quite good gear ...


Even though sharpness is not an end in itself, this bad habit comes from the impression of not getting an overall sharpness impression at 30 or 50 (not a 100% peeping).


Sure, I've made some tests on tripod with mirror locked, stopped down a bit or more and so on, but I feel something is wrong. Following your explaination I will do some more tests anyway.


That's why I wondered if some sharpness tuning on the cam is a good idea and if it's not worsening things.


Second : might it be the cams ? I know sending back the lenses for calibration is usual ... but the cams ?
