This is a seriously heavy piece of equipment,weighing about three pounds more than Canon's 800mm, so get your support right.The Manfrotto 475B does a great job with the 393 head for sensible money.

"This is a great camera overall, the pictures are terrific, i got the pack, the leather case is a nice touch, it has awesome features like fisheye, slow motion video, etc. The video quality is terrific and i definily recommend this camera!"

I have been using the Canon version of this lens & it is sharp wide open!! No stop down required unless you need DOF! Focus is fast & accurate. The first thing I did was do a true test of it's sharpness wide open & it's sharp.
