Canon 24-105mm is L series lens
Hi all, after a bit of advice here, I have several lenses and by far my all round favourite is the above, recently I'm having focus issues with the lens whereby when using spot on eyes etc I manage to get a nasty blur when I download the images to PC, The lens is very clean, I have tried high ISO, tried flash etc etc but cannot seem to get a good AF.
The lens is on my Canon 5D MKII and has been used for approx 3500 shots. I know there is a micro adjustment in camera but don't want to touch this not knowing what the hell I am doing with it.. I'm still reasonably new to DSLR this being my first one and purchased a year ago.. Any help would be muchly appreciated.. Tar

As John says "does this happen with any of your other lenses"?
As for MA-ing your lens this is very simple, download a focus test chart. http://www.dphotojournal.com/downloa...us-test-chart/ however this will only adjust the camera/lens for front or back focus. I guess you need to check whether indeed this is front/back focussing. I assume you have switched to manual focus and used Liveview at full 10x magnification, if only as a test. Harry

Does this lens have a UV filter fitted ?
If so have you tried it without ?

Yep tried without, Just looking at some of the images that were ruined, when you half depress the shutter on the eyes and re compose, press the shutter and take the pic, in DPP will it always just show where the centre AF point (Highlighted Red) was when you took the pic rather than where you metered from?

Right I fired off some test shots and it seems to be not completely sharp across all three of my lenses, with auto focus, with manual focus I can get pretty much what I want..
In Canon settings, what is the default setting for AF is it stop or start as I used to have no problems with this beast, it has never been dropped or knocked I have taken much care with my lenses...
