So I'm ready to get serious about taking macro shots with my G1. I have a great lens in the Tokina 90mm/2.5, and I have what I think is a nice tripod, but I know I'm missing some other gear. Here's what I think I need.
1. Remote shutter release
2. Focusing rail
3. Flash or some other light source
4. Tripod collar (maybe)
5. Flash controller (maybe)
I don't need to go all out super expensive, but I'm ready to spend some cash where it makes most sense. I think I can get away with a simple 2-axis focusing rail for the moment, but I don't know if I need a new head for my tripod to use it. My biggest unknown has to do with the lighting source that I can use with this camera. I'm thinking I'll want a flash unit that doesn't have to sit on the camera but has a chord, but that I can either mount (preferred) on some sort of adapter/collar or hold (by hand) so I can illuminate the small area in front of the lens without worrying about the lens itself shadowing the subject.
Any suggestions would be greatly appreciated.
