Thanks for your suggestion - I only have one lens unfortunately.

I might go to local camera shop and ask to try another lens with it, but not sure how helpful they would be.

I have just bought a second hand K110d from ebay and the autofocus is not working

I was wondering if anyone knew of a simple fix, or if not someone could give me an idea of how much these things cost to repair.

Symptoms:
- In AF mode lens focuses back and forth a few times and then fails to find focus lock (green hexagon flashes in viewfinder)
- In manual mode the camera works perfectly, INCLUDING the focus indicators! (so the camera knows when it is in focus)

PS using the kit lens and have tried cleaning the lens & camera contacts

Many thanks
