Originally posted by marcusBMG I an getting quite frustrated with my KS2 + DFA 150-450mm. Persistent to and fro focus hunting sometimes fails to focus at all, often missing focus. I have been trying different settings: AFC vs AFS, spot focus vs zone focus. Any ideas?
I used MF for many of the pics of the kingfisher.
Hi Marcus. No expert - still fairly new to the 150-450mm myself, but I definitely get better results for perched birds/birds on the ground with AF/C (or just straight AF) but definitely with Spot focus (except for BIF where I am experimenting with Select (small) as the focus or active area.) I also try not to operate below 1/800 second (esp hand-held). Always with Shake Reduction On, except for very still subjects when I am using a tripod. But even with a monopod, I do better with Shake Reduction on.
Also, you need to make sure what you have set the 150-450mm lens focus setting to - full, distant or close focusing only. Caught myself out with that once or twice after setting it on to the near focus setting and forgetting that, and then wonder why it won't focus on distant objects!!!!
I also use the half-press of the shutter button - never have made any real effort to learn to use the back-button focus!!! One trick too many for this old dog!!!!!!
