Hi,
Thanks for the response. I've tried to clean it by using a blower with the mirror up, but it looks very clean inside. After the cleaning I took about 1000-1500 images, mostly of flying seagulls and thought the autofocus was OK. But right before it was time to go home it failed again. I had just focused on a stone 2 meters away, and then when I tried to focus on the mountains in a distance it just fails. It cannot focus. There is plenty of light and contrast.
I have done the same test several times during todays testing and it worked every time so I really thought the cleaning did the job. But failure again right before I was going home :-(
So I guess I need to send it in for repairs......Show more →
You can distinguish between a AF sensor issue vs an AF motor/drive issue by switching to MF, entering LV, manually focus at maximum magnification, then exit LV (staying in MF mode) and half-press the shutter and see if you get an AF confirmation. If you get the AF confirmation that means the AF sensors are working ok and it's a motor/drive issue; if you don't get a confirmation that means it's the AF sensors (either malfunctioning or obstructed).
