Mmmm can be a useful method but in some situations the focus-recompose technique should be used with caution. See here for details:

I understand that focus-recompose is not always the best way to do things. But so far I have had very good luck using it!
And using it for NightShots has helped quite alot. And in the dark with out flash it can be hit and miss at best.
That is what I am learning ,to make and take night shots. I love taking photos in the dark. The things brought to life that we mostly never see!

Thanks for the article. I'm glad that my long held suspicions have been confirmed. I found this particular bit very illuminating.

Quote:
The error introduced by focus-recompose is greater with shorter camera-to-subject distances.


That would explain why many of my macro shots looked out of focus. I focus locked on the subject and then composed my shot. For the last few weeks, I've begun to set my AF mode to local focus, allowing me to manually select which AF point to focus on.

My shots have become way clearer and better.

Thanks Mark for that article. Shows I'm not manually selecting the AF points for no reason other than being to lazy to recompose the shot.
And, yes, HoodedOne, I have heard of focus lock :roll: .

Good, I was getting worried :D

As for the Story of focus-lock being cause for out-of-focus pictures. I'm not convinced :)
If you do a google search, you'll also find articles that proof the opposite.

Don't be. I think I know pretty much all there is to know about the A700. If not, I'm always eager to learn :) .

Could you link to "articles that proof the opposite"?
