I'll have about 400 dollars to spend on accessories in the next 2-3 months. I currently have: Canon XTi Speedlite 430 EX II 100mm f2.8 macro MR-14 EX Ring flash Sigma 50mm f1.4 68mm of Kenko extension tubes 18-55mm (non IS) kit lens L-bracket and off-camera cord Tripods Any suggestions? I'm looking for general accessories, they don't have to be lenses or flash units. I just ordered two 500Gb hard drives (one for data, one for backup), and I have pretty much all the software I need. I have been looking at general zooms (17-70mm range) or UWA lenses, but I'm open to suggestions.
