Hi, I am new, not very experienced, and asking for advice. I am an avid gardener and am thinking of buying a macro lens for flowers, i.e. photos of individual flowers. I have a Canon 30 D, and one lens, the Canon EOS 17-85 IS USM f/4-5.6. I also have a couple tripods and a flash, but I didn't buy the little cable for pressing the shutter without touching the camera (can't remember what it's called right now). On my first visit to the camera store, the EF 50 mm f/2.5 compact macro was the only lens recommended. On the second visit, a different employee recommended either the Canon EOS EF-S 60mm f/2.8 macro (same price as the 50 mm right now due to rebate) or the slightly more expensive Canon EF 100 mm F2.8 macro USM. He leans slightly in favor of the 60 because it's lighter weight, and because the 100 might be too much magnification for, say, a rose which is 4 inches across. Will one of these macro lenses take signficantly better close-ups than the lens I already own? Which macro lens is right for flowers? Will I need a tripod and shutter gizmo in order to use a macro? Will I need a hood or any other accessories?? Thank you, thank you, for any advice!!
