Hi

I too have the same camera and same problem, here is what I found.

After experimenting, I discovered the problem with the camera. It would appear that the guiding mechanism for the lens has shifted out of true/alignment or has worn.

I notice that when I
open the camera face down or on its side, the camera will focus, however when I open the lens horizontally, the green focus light continues to blink. If one supports the lens and lifts it slightly, then it will focus. The lens appears to droop in the horizontal and this affects its focusing abilities.

I have been quoted $180 CAD to have it repaired here in Canada, more that the camera is worth....

Regards

Problem: Same camera Olympus Camedia C-720UZ used for 4+ years, and for several months now, no or very very rare AF lock at infinity when zoom set to highest focal lengths from about 200 to 340mm+ (35mm equivalent). Other focal lengths, other distances: ok. It's not a problem of low light (shot during daytime) nor shake (a tripod was used). During the AF 'search' I can see in the viewfinder that it goes through the position where it's focused, but will hardly never select it.

After reading this topic, suspecting dirty or misaligned optics I disasembled and cleaned the first 2 lenses. The first lens is maintained by a plastic ring that can be unclipped with a small screwdriver. The second as a rectangular frame glued to its edges and is held by a bigger ring with 3 small philips screw. After cleaning and reassembling the zoom, AF did not work better.

On the second try for I tilted the first lens when assembling again (just for fun). Then I noticed the AF now locks in all situations, but the images suffer chromatic abberation on the edges and apparently geometric distorsion.

Of course such an experiment does not seem like a working solution but can it provide a hint as for the AF problem ?

Thanks for advice.
