Oh yea, it's out and about. Marines, Air Force & Navy all have them. There aren't a lot of them (wiki says 100, I'd guess more considering two were at a single air show), but they're out there.

For today's photos, I turned a camera on my camera because it's gripped now and looks sexeh.





...and the back



Wrote a quick review of the grip here at my site. It's not bad for ~1/7 the price of the Canon grip.
