I am doing cap n gown portraits for some underprivileged high school graduates this weekend. I was doing some test shots today, and noticed that I am able to get a lot closer to the subject with the 85 on my 5D than I did on my Rebel (Duh )
My question is will this be ok? I hear people talk about distortion and making your subject's head appear too large in relation to their body. Is this only with Wide lenses, or anytime you are within 3 or 4 feet of your subject? The only other lens I have is my 24 - 105, and I would really like to shoot at least f/2.8 in order to get separation from my backgound.
