Anyone else experiencing autofocus problems with thier 1DS3? Now on my third body, first 2 has focus issues and viewfinder alignment problems. Now the third body, (or is it body) seems to be behaving as the other two did. Using centre focus point only, and on static subjects, the camera seems to have problems focussing, mainly at longer distances. For example focus on something 1/2 km awy and it focusses 30 meters away, manually focussed things are rectified. This happens mainly on the 16-35MK2 set on the wider end, put it on 35 and it's ok. My 85 1.2mk2 exhibits similar problems, as does my 50 macro, however my 135f2 is perfect.
I never had these issues on my 1DS2 with any of these lenses, and quite frankly i want to throw the whole lot off a very high building!!! It's driving me nuts.
Any ideas, thoughts, Body or lenses or both?
John here from Australia.This is my first post also.I have had similar problems and have just left camera with dealer after he did testing and confirmed problem. It is wierd. I have set up on tripod to take shot of static object ... a 24"x36" sheet of newspaper ...with a
range of lenses...100m2.8 macro, 70/200 2.8 is ,85 1.2 ,50 1.4 and 24/105 4 NONE of them focus properly...this is when the centre focus , single shot AF mode is on. It is noticeably better when the servo tracking is on.. still not perfect...when the camera is set to live view and manual focus it works perfectly.I figure it is no use using the custom function to adjust lens because the focus is so different between servo tracking and single shot.I have tested it against another 1ds3 and 2 x 5d they are all much better. I would be very interested to hear of anyone else with focus issues.
Will let you know if Canon have anything to say when I get it back... soon i hope as I love it warts and all !
