I've searched but couldn't find a thread that answered my question so here's a new one for you guys.
When focusing on a point (person, face, tree, etc.) sometimes I would have to half-press the shutter button several times before the red dot would light up indicating the correct part that I want to focus on. When using the Canon 24-70mm lens I had trouble using the AF point all the way to the right. For example, when taking portraits I would like that point to focus on the face and that means pressing the button a bunch of times before the red dot lights up (10-15 times).
When using the kit lens (18-55 IS) I noticed that it was easier but I would have to move the camera so that it could "pick up where I want it to focus on." At first I thought it was the lens but it might just end up being the camera. Any thoughts/comments is appreciated!
