Focus issue w/TM900

With snow falling I was trying to capture birds at the feeder. To my surprise the auto focus was not very focused at the long zoom. It is too much of a strecth to think the falling snow threw the system a curve? This is the first flaw I found of the camera if indeed it is a flaw.Hopefully, not a condition for repair.

Re: Focus issue w/TM900

Hi Mike,

Does your autofocus work OK on scenes without snow?
The only problem I have had with the autofocus is that is does not necessarily focus on what I want it to focus on. I find using manual focus with the focus assist very useful when the camera is presented with a number of objects at different distances such as a bird in a nearby bush.

The autofocus system will get confused with snow and by default will try and focus on the object nearest the camera, same applies for any auto focus system.

Manual focus is designed for just such scenarios.

Re: Focus issue w/TM900

I had a similar problem recently shooting my daughter when she jumped out of a perfectly good plane (skydiving). Autofocus struggled to focus with soo much blue sky. I simply quickly changed to manual focus with focus assist and grabbed some great footage of her parachuting in.

Re: Focus issue w/TM900

Thanks for the replies. As I tested the focus inside it appears that it is working OK. What perplexed me was that some of what I shot was in focus while the very next shot was out of focus. I didn't do anything different shooting the same subject at the same focal length. I 'll have to test it farther. Thanks again.
