Thanks for the info. John.
Do you like the larger eye cup?
I've played with it around the house for 4 days now and I'm taking it out to the lake tomorrow and see what I can do with the 40-150. I usually shoot birds and landscapes out there so I'll really know what the IS is doing for me with my V-LUX 1. So far it ain't lookin' to good. I normally shake quite a bit so I'm taking my monopod.
