Interesting, I didn't know there are 2 ois settings on this lens.
I was shooting a soccer game recently and set the shutterspeed to 1/1000. Based on the answers above, it is still not clear to me I'd better turned it off or on
I have the 50-140 as well, and the 16-50, and am also looking for a new bag. I already have the Retro 5 by the way.
Is the Retro7 better suited than the Retro10?
