I assume the only use for these 600mm and 800mm F11 lenses would be perched birds. I can't think of anything else. The moment the birds start to fly, these lenses will be rendered useless as it is hard to imagine shooting BIF at less than 1/500 even for large birds, to keep them sharp. With perched birds, due to excellent Image Stabilization, you may get away with much slower shutter speed, assuming the bird sits and does not move much.

Now of course another question is if the lenses are optically any good. as we remember Canon has some really good DO lenses, and also some duds.

Bright Sunny Day - Ev15

ISO 400
f/11
Shutter speed -> 1/1000th

ISO 800
f/11
Shutter speed -> 1/2000th

Bright Cloudy Day - Ev13

ISO 1600
f/11
Shutter speed -> 1/1000th

For the price that doesn't suck...
