Interesting & helpful information

[Grandpaw]

Someone sent this to me and I thought it was information worth passing on. If you use auto focus and recompose your shot slightly afterwards you may find this interesting, Jeff

That is interesting, Jeff.

Thanks! I will have to reread this lol

Yeah, nice to see someone break it down like that. But to me, this is all just common sense.

Of course the spot of focus is not always going to be exactly the same when you reposition the camera after activating an AF point. There's a thing called depth of field that is meant to cover that discrepancy.

You should know to only use this technique when you have a decent DOF as a safety net...

Also, most advanced DSLRs have selectable AF sensors, so of course you would always prefer to focus with a senor activated right on your subject so you don't have to reposition the camera.

Pre-focusing and repositioning the camera is done only when you have no other choice. It's a much better technique than nothing!

Like any shooting technique, you need to know how to use it...

I agree about the common sense point of view. The reason I posted this is due to all the pictures of flowers, portraits or close ups that the point of focus was off just a little. This just explains this problem and reminds you to think about it, Jeff

Definitely. Again, the main rule of thumb to take from this is to keep your focus in an arc. When you pre-focus, then recompose, make sure the object you want in focus remains the same distance away from the lens...

yep, good article. I learned the hard way a while back that focus and recomposing did not provide consistent results and ultimately is not a good method (unless as Steve mentioned there is no other way. . )
Now I have become pretty good at quickly selecting focus points with the little thumb joystick selector.
thanks for the article

Hmm, interesting.

I am going to use the 3-point or 9-point AF more frequently now, instead of focusing-recomposing.:thumbsup:

Thank you. As a total beginner, that was something (obvious when pointed out) that may have taken years to notice. - TF
