Thank you for the tips. I actually have a sb700 and right before the shoot I purchased a piece of white poster board and didnt use either. Out of 100+ photos that I took I only liked about 12 of them. I used the view finder for the first time on this shoot and found that I missed focus on a lot of them. Is that common?
I haven't read the whole thread yet so I don't know if anyone has already answered this but when you first start manual focusing yes you will miss the focus a lot. It is a skill and you will fine tune it as you go. Occasionally you will still miss your focus but the margin you missed it by will become less and less as you learn to pay closer attention to the point you want to hit the precision focus on in the shot.
Just to be clear, my understanding was that the OP was referring to using the camera in AF but composing via the rear LCD rather than with the pentaprism viewfinder. It's not uncommon to miss focus, no, but it's also very simple to get right. Almost always when shooting people & portraits, the eyes are the critical element. Therefore, choose single point AF and place that point over/between the eyes. DO NOT use focus and recompose, especially when shooting with larger apertures, longer focal lengths or short camera-to-subject distances; you're more likely than not to go wrong! Manual focus using the focusing ring on the lens barrel is not something I recommend unless you need to do it that (an older, MF lens) since todays cameras are NOT designed for manual focus. They lack the split-prism style focusing screen of their older film brethern and it can be difficult, especially with a pentamirror viewfinder and slow lens to get enough light to ensure critical focus.
