Just a "basic" Canon t1i (now discontinued for a newer t series version), plus one of Canon's awesome and premium "L" series lenses . . . the Canon EF 200mm/2.8 L II.
I love that lens, and the incredible "pop" it gives to colors, textures, background blur (aka "bokeh") and clarity.
I have a T1i and I love what it can do. I took this with a 50mm F1.8. My dog was sitting next to an open window. Notice the whiskers. Click for full size image.
