Below is a list of the gear I use:
Canon 7D - My main camera (for the time being)
Canon 100-400 4.5/5.6L - This is what I use to take the majority of my bird and wildlife shots
Canon EF-S 15-85 f/3.5-5.6 IS USM - Most of my landscapes are taken with this lens
Gitzo GT3541 Series 3 Carbon 6x 4 Section G-Lock Tripod
B&W Circular Polarizer Filter
B&W UV Filter
Other Equipment:
Quite a few of my photos from Costa Rica were shot using a Canon EF 600mm f/4L IS II that I rented specifically for the trip. (Hopefully, I'll be able to add this to my lens bag one day soon!)
Editing:
I primarily use Photoshop CS5 for all my editing, though I do also have Adobe Lightroom 3, but I use it much less frequently than I should.
