Originally posted by Nicolas06 This doesn't work that well on shallow deph of field shoots let's say 50mm f/1.4. As the deph of field is quite small (arround 1cm), the recompose mean the focus is no longer on what you want (the eye for example).
Good point. I rarely shoot less than f/11, sometimes f/8 if I'm daring
so not really an issue for me.
Originally posted by Nicolas06 But as far as selecting focus is concerned, on can always reframe a bit the picture if needed and having more points mean more time spent selecting the rigth one... not really that usefull.
Yes, focus and re-compose is what I am used to. Fiddling with the AF points seems to me to be just that, fiddly. I have certainly used it, when I remember, but mostly it seems to be one more thing that gets in the way of me taking pictures.
Originally posted by Nicolas06 For tracking and auto selection AF the more points the camera has, the more it can have a precise deph map in combination with the exposure sensor and the more it can understand the scene and help with the AF.
Yes, I can understand that.
It seems the reason that I don't understand the need for more points is that the only situations where that is an advantage are things I never, or rarely, do. Good enough, thanks for the information.

Ok, after thinking about this some more one thing still puzzles me.
I shoot with single center point when not on the tripod and when on the tripod single select and move that point to where I want the focus to be. So 1 AF point = 1 area of focus. I have a 100% chance of getting what I want in focus.
But if I have a camera with 65 AF points in auto or whatever it is called and I take a picture the camera will select one of those 65 points to be the focus point. So I now have a 1 in 65 chance that what I want in focus is going to be the focus area.
Now, I am sure I am missing something because otherwise people would be clamoring for less points not more so what am I missing? Maybe I am old, but I just cannot figure out how having 65 AF points does not cause chaos.
