I currently am in the market for a tripod, 60mm f/2.8 macro lens, and GND/ND/CPL filters. What do you think is the best thing to buy first? I can only afford one of the things first. For the tripod I was going to get the 055xprob w/ 498RC2 head. If I got the tripod, I would probably get a filter or two for my wide angle (CPL or ND first). However, I'm not sure if a filter/tripod is more important than the macro lens. I eventually will get them both but what do you think is the best for now?
