A friend of mine is getting rid of his Canon 75-300mm f4/5.6 lens. It's the non USM, non IS version. It's listed on the Canon site at £250 odd, which doesn't mean anything i know, he wants £80 for it, along with a soft bag for it (which i don't really need), a UV filter and another filter, not sure what that is, it says PL on the side of it?
Is it worth it? I can't see any on e-bay, they are all the USM version, which i presume is better, and going for £130-150 ish.
I know he will have looked after it and the few shots i took with it are ok (within my skill range)
Thanks if any of youguys and gals have any opinions
