This was taken within 2-hours of opening the box from B&H containing my new Canon EF 500mm f/4L IS lens.
This was shot with said lens on my 7D with the EF 1.4x TC II and an Induro C414 tripod, with Arca-Swiss Z1 ballhead and Wimberley Sidekick (which works very well with this lens -- smooth as buttah) at the following settings on an overcast afternoon:
ISO 400
0EV
Aperture Priority
f/5.6
Resulting in 1/1000-sec
RAW plus jpeg
I was going for the bokeh and used a shutter burst to capture the bird in mid-song.
RAW conversion was done in DxO's Optics Pro 6.1.1, pulling the RGB curve down a little while adding a touch of contrast and just a few points of Saturation.
BTW, the valve is actually not level, so I didn't level it, but now I'm thinking that maybe I should have because it'll always be a question in peoples' minds. Let me know if it bothers you or not please.

All suggestions are greatly appreciated. :cool:
BTW, using the EF 500mm after shooting over 10,000 shots with my EF 400mm f/5.6L seems almost like "cheating." My "Keeper" rate has gone through the roof. :D
