if you do buy a 2xtc to go on your macro you dont need to spend oodles of cash - mine is the jessops own which is 39 notes
i agree with jason that an ext tube is also well worth a look as well or instead - jessops have these also for £79 for a set of three |
Mmm, I'd never considered using a 2X with a macro lens, I never had the sense to try it when I had mine. I wish I had, it could have worked well with a faster piece of glass.
It certainly didn't work at all well with the 50-500mm..F12 at best, soft being the kindest description I could say for any images I got with it. Suffice to say I sold both converters. Very disappointing.
