i am in need of a good macro lens. i have a telephoto/"macro" lens, but 70mm is too far away....i need to be able to get close (ideally right in there, but DSLR are not good in that regard it seems.... so closer the better. I really need something that can catch detail really well of insane close ups (i am doing things like plant skin cells, pollen, flowers etc etc...also with a microscope but still need the macroscopic shots). DOF is important, and *most* subjects will be still (not so many animals, mostly plants/fungus) i use cannon EOS digital (kiss x). the problem is i am limited for $, so gotta be under $500 USD. until I saw the price i was looking at the MP-E 65mm f/2.8 1-5x Macro, but costs too much for me. also looked at the Canon 28-105mm f3.5-4.5 Macro USM, anyone here worked with this? how good is it at getting in there and details? any ideas?
