I really want to do a well exposed series of slides. I am secure in the theory that the F4 will do what I want, reasonably easily. The MF-23 is a very interesting device, but it is expensive even on Ebay. I'm seeing them averaging over $100.00. I really do need a MB-20 to cut down the weight. MB-20s seem to be running about the cost of a MF-23.

I tried the F4S already with a 300mm lens and was surprised at the lack of vibration. I'm not sure how this translates to what I've done as I don't have the negs back yet.
