1) at 5mm ( with the 02)
2) at 400 ( with the sigma)
VG!
The OS version of the lens has indeed a good reputation
Don't hesitate to share other tests
Steve Nunez had good results with the Sigma 170-500 and an "old" Sigma 70-300
Bigma not good
Sigma 70-200os VG

Originally posted by vonBaloney With really long lenses, try using shake reduction at different settings, even on the tripod. With the Q7 and the 600mm, I was getting my best results with the focal length set to 800mm and SR turned on when on tripod but using handheld shutter release. I find that works better than using a delay or remote release and SR off unless there is absolutely no wind and I can let it settle. (Even with an APS-C body and long lens, I will often set the focal length to 66-80% of the true value when on tripod, using 400-500mm for the 600mm lens -- of course it won't let you alter the value on AF lenses which is a drawback I think.)
Tripod and SR turned on works definitively. (Edit : Q & Q7 only!)
In steady conditions, remote release is better for me.
But I didn't try to cheat the SR with a longuer focal lenght.
Probably worthy in windy conditions, I'll give a try next time.
