I'm pretty new to dslr cameras and am about to buy a new lens. I want a lens that will let me take good closeup shots of flowers and is also good for portraits. I'm not really interested in photos of small insects. Two questions: 1) While the 90mm lens may allow me to get "closer" when taking shots of flowers, wouldn't a 60mm do the same thing if I just put the lens closer to the flower? 2) Which lens would you prefer for portraits? My gut feeling says use a 60mm but I'm interested to hear what people with experience have to say.
