I use an older Canon D-60.
I have three lenses. I use the EF 17-40mm f/4L USM 99% of the time, since it's perfect for both portraits close to the subject:
I also have a EF 28-135mm f/3.5-5.6 IS USM and a EF 70-300mm f/4-5.6 IS USM lens. The IS can't be praised enough. It simply allows long zoom shots in marginal light or of moving subjects without the use of a tripod - a huge advantage, in my opinion.
I do have a Hakuba carbon fiber tripod w/ Really Right Stuff quick release clamp and mounting plates. I use a Sigma EF 530 DG Super Flash EO-ETTL as my speedlight, and a nifty Pelican case to keep everything but the flash and the tripod safe from water, sand, dirt, etc.
