I have a query about focus using my Olympus E520 with the 40-150 kit lens. I used this combination last year at a model air show and had the greatest difficulty getting the aircraft in focus.
Initially I used single-point focus because there was background in the picture. When the aircraft were in the air I switched to 3-point focus as I found it impossible to get a lock on a small fast-moving plane with one focus-point. It was still nigh on impossible with 3!
It has always been difficult to focus with this lens at full-stretch so I usually rack it out to the full extent then just roll it back a toch and try to focus.
I wait for the green focus-confirmation but not always for the beep (and in noisy surroundings often can't hear the beep anyway.
