I am searching for a tripod mount for macro use that would allow me to shift the lens position in order to fine tune manual focusing. I have not had any luck searching catalogs, Wimberly, or my local camera dealer. I am probably not using the right keywords for my Internet searches. I would have expected to find something with a rack and pinion drive or, at least manual adjustment that didn't require shaking the camera too much. The closest thing that I found was a long Wimberly Arca-Swiss type mount. I would greatly appreciate any suggestions.
