Canon EOS 1D Mark III lens mount_Rollei QBM/SL The battery is deadThe EOS 1D Mark III is a big body professional camera with that APS H 1. 3x crop sensor that I'm pretty sure only Canon ever used. That modest crop, along with the 10mp resolution, gives this camera the ability to shoot at up to 10fps. That's reasonably impressive now, and it was a really big deal in 2007, when this camera was released. There's no video functionality here, but there is live view, and you can shoot to either SD or CF cards (or both!)
