If you are not using time delayed function, do so. also, using a wired or wireless remote will help. you can try shake reduction on and off and compare the results.
Thanks, I always use the 2sec. mirror up delay, but no cable around this time. Seems like this lens needs just the same treatment like a conventional long lens, and that's a real sturdy tripod first, it was dangling in the wind on the small one. Did not try SR on.

G'luck with the birds,

Sigma QX 500mm f8 mirror lens

Anyone out there ever used one of these? or know what the IQ of this lens might be?
