Originally posted by amarsh1958 I started to wonder how many of you have had to use the AF micro adjustment on your Pentax K-1? I discovered that in some circumstances that the image quality was disappointing especially when I went pixel peeking. After a little testing I discovered that it back focused with all my lenses. So after a bit of experimentation I found I needed a general micro adjustment AF and a bit on lenses, it now hits focus perfectly. I actually used the rivets on my garage door, photographed at 45 degrees and centre point focus and this works perfectly for me and as others have said it is not scary as you can reset it if you go the wrong way.

I use focus confirmation and -6 adjustment for all my manual focus lenses. Many of them are brighter then f2,8, and I shoot wide open, so even after focus confirmation start to beep or green hexagon appears, images are not always in perfect focus.
