Congratulations you will love it. Just take it slow and let your experience level grow. Some people just go off and take a million photos and they don’t turn out to good and get down on camera and all that. Only to learn it was not the camera. There’s just a learning curve and getting to know how to get the better results they are looking for. One tip I found helpful at first was to use just one focus point and not all 19. So it will focus on what you need it to. Congratulations
I STILL only use the central focus point. If I want the focus point not to appear in the centre of the frame, I just focus on it in the centre by half-pressing, and hold the half-press while I move the camera to re-compose the shot, before letting it rip.
I confess that in my ignorance, I don't see a lot of point of using more than one focus point. I have read that section of the manual but I was not a lot the wiser afterwards, about why you'd want to use >1 point. I mean, do you have to use the mini-joystick thing to select the focus point to use, if you're not just using the central one? Isn't that awfully fiddly, if you're holding the camera with the viewfinder to your eye at the same time?
And I believe there is a mode in which the camera will select one of more of its focus points to use, for you, using some kind of algorithm. Again, why? I doubt it'll "guess right" all the time which object or objects you want in focus.
I admit that my lack of understanding of these issues is my own problem and that there must be good reasons for these facilities on the camera, but I need educating!
