As of May 2011, I have been shooting with a Nikon D90 DSLR as my main camera. To go along with this, I've got 2 lenses: a 18-55mm, and a 70-200mm. They're both fantastic, with quite different uses. I also have a polarizing filter, which I've used a few times, and next weekend I will also have a remote to take very long exposure photos.
My secondary camera, which accompanies me on field trips with less "me" time (or limited space!) I use my Canon Powershot SX100 IS. I've had this camera for about four years now, and it's pretty darn amazing for what it is!
My newest sidekick is my iPhone 4 (and instagram, once in a while!). I can't carry my Nikon everywhere, and this phone has HDR built in, which is pretty fun! I've already posted some photos from it, and I'll continue to do so - when they're worthy of it.
I also have a tripod (which isn't quite tall enough!), although I don't use it all that often.
