now I did a quick search, but really wasn't to sure what key words to use so it came out flat.
None the less this is the issue I'm having.
When I use auto focus and focus in on a subject the AF point will light up red, looking through the view finder the image appears far from "in-focus" however when I take the photo and look back at it on my camera or the computer it is in fact in focus like the AF point suggested.
Whilst using MF and focusing something which to my eye looks correctly focused, after taking the image and looking back at it, it's in fact out of focus.
I printed of some focus charts to make sure my eyes weren't deceiving me, and yep AF works great, but just appears "off" through the view finder.
Tested this using 3 lenses, 18-55mm, 50mm and tamron 90mm
any help much appreciated, and quickly since I'm going into the city to inspect and potentially buy a 24-105 tomorrow and really do want to test the focus on that properly
