I took this from the doorway of my room with my camera with a lens that had one single aperture. This particular plant was about 20 - 25 feet away. Focus still looks slightly fuzzy, no matter how much I was trying to rack focus.

Info:
Camera: Canon Rebel XTi
Shutter Speed: 1/1000th second
Lens: Quantaray 500 mm f/8 lens
Aperture: f/8

Comments, questions, concerns.
