Your comments on the thumbwheel are SPOT on lgreen.
Is this the same on the Vaja....Unfortunately I will just have to see as I have mine on order already .......
I've read good things about the Krussel but the fit on the top part is unacceptable to me. It's too loose IMO. Loose like not coming out, but there is too much play. It is not SNUG tight to the body and kinda *wavey* in the center of the top. I'll grab some pics later on when my UPS drops off my new Nikon lense
