Hey Moose and Bruto. I am sold on the Manfrotto xume suite and I am going to order it in the next few days. I'm starting with a B +W 10-stop filter for shooting long exposures of waterfalls.
I'm having trouble though locking the focus on my D3100 for long exposures. I am referring to the manual on pages 37-39. I just want to lock focus not exposure and I'm not sure how that's going to work in bulb mode. For now I have been manually switching off the Auto Focus and VR by hand but I keep on bumping the camera just enough to lose focus. Any suggestions?
