I'm trying to work out a deal with a guy locally who has a Sigma 70-300mm HSM lens, a Sigma 28-70mm HSM lens, a Digital Concepts HD 0.45mm Wide Angle, a Digital Concepts HD 2x Telephoto, a polarizer, a uv filter and a filter that he says is a fld (don't know what it is ). He wants $300 for the whole shmeer which seems like a great idea. Just wanted to know: I know for a fact the digital concepts lenses are completely useless so I'm trying to talk him to $250 for everything but those two lenses. Are the two Sigma lenses and filters all worth going for? Money is really tight for me so I want to know I made a good investment and got a good deal on lenses. I dream of having a telephoto (and a wide angle too someday ) but I'm a student on a budget so coming across these deals is sort of a make-or-break decision. Assuming these lenses are in excellent condition which he says they are, should I go for this deal? They are Canon-mount lenses. I've read reviews saying these lenses are quite good. Any experiences or questions I should ask him?
