I use very simple gears (that's what call them, but believe me none of them comes inexpensive) and try to travel light (but always end up carrying 3 to 4 heavy bags).
I have these things:
- Nikon D700 (with a MB-D10 battery pack).
- Nikkor AF 50mm f/1.8D.
- Nikkor AF-S 24-120mm f/3.5-5.6G ED IF
- Sekonic L308s light meter (its a basic one and works for pretty much all my needs).
- Nikon SB-600
- Vivitar 285HV
- Some small inexpensive flashes.
- 4X4 inch, 24X24 inch and 36X36 inch soft boxes.
- Colour gels for the flash guns.
- 30 inch and 42 inch diffuser and bounce umbrella and brackets to attach them to tripods/light stands.
- Lots of sync chords.
- Cactus V2 radio trigger and receivers.
- Manfrotto 055x PROB tripod and 498 RC2 ballhead.
- Some inexpensive light stands and tripods for my lights.
- Lowepro Prorunner 350AW and Toploader zoom carriers.
- And lots of other stuffs not worth mentioning here.
