Auto Focus Problem. Urgent Help Needed Please!
Posted: Mon Apr 25, 2005 10:12 pm
Hi All,
I recently received my camera after a three month wait getting it repaired by Maxwell because my camera went to sleep one night and never woke up (ended up requiring the power PCB to be replaced). Today was the first real ‘day out’ with it and I have noticed that now my camera's Auto Focus is playing up.
When I half press the shutter button to acquire focus the camera goes through all the motions of Auto Focusing (AF) but the focus is slightly off and causes my pictures to be blurry. Now I can get around this with some of my lenses, like my 17-55mm for example because I can fine tune the focus manually after the camera has attempted its AF routine. However, this is a really big problem for my 85mm lens because I have to unlock the focus ring and set the ring from AF to M then fine tune and as I am sure you can appreciate that extra time can make all the difference.
Now I have tried almost everything I can think of to rectify the problem with no success, hence my appeal to you for ideas (as I don't want to sed it back to Maxwell for another three month turn around).
I have adjusted the following settings with no difference to the camera's slightly off focus when using AF.
AF/M switch on the camera body - AF no difference
AF/M switch on the lenses - AF no difference
Auto Focus AF(S) and AF (C) - No difference
AF area mode - all settings. No difference
AF assist (shouldn’t matter) but again - No difference
AE-L/ AF-L in AF - No Difference
Focus Area (On/Off) no Difference.
Any suggestions or ideas would be greatly appreciated.
Thanking you in advance.
Mick.
