Sorry if this seems a silly or pointless question. I still haven't bought my SLR yet. I had been thinking about the canon 450d. Im just trying to read as much before I finally buy as i've never used an SLR before so want to be aware. There are a few things confusing me.
When reading about the auto focus, it says it has nine points I understand that this means there are nine points that focus on whats near to it. I've read a few places people saying shoot on centre point, why is this?
Also i've seen some pictures taken on the 400d, 450d (not on this site) and other brands of camera where for example there are 3 subjects ie dogs in the picture with some background but the dogs are out of focus... is this the wrong setting, camera or lens? Ive never had this problem with my p+s everything is mostly always in focus, not too sure what kind of focussing it has all I know is in live view there is a little rectangle in middle.
I had a shot of a nikon SLR and the same thing happened, when its close up head shots they were in focus ok but a shot of my dog standing in the middle of the image was a bit soft and out of focus.. I know it was probably my fauly just wondering what causes this in so many images I see as I always like everything in the image to be nice and sharp.
