| p.1 #1 · Question for owners about Sigma 150 2.8 OS |
I purchased a used Sigma 150 OS. firstly the lens rattles when shaken. When I look in the back I can see the stabilzer group moving as I rotate the lens, does anybody know if this is normal? The heavy part of the stabilzer group (thee rear) stays at 6 o'clock when rotated. When I press the focus button, (power applied) the rattle goes away while the image in the viewfinder sometimes jumps into the correct position, centered. It's kind of similar to the old Nikon 70-200 2.8 VR 1. Any ideas or comments?
