Minolta Focusing Rail AB-III

I am searching for a focusing rail for shooting macro photography. I came

across the Minolta Focusing Rail AB-III, which has a flash hot shoe at one end

and a camera mount at the other. Does anyone has this focusing rail and is

using it for macro photography? How is it?<div></div>

I use one with a macro lenses in the field if I don't take the AB III (new). It's only problem is

with some lenses that rub against the rail when mounted in line with the rail (over the hot

shoe). This is overcome with a washer or something similar (low profile panorama head)

between the rail and camera body. The one in your photo is missing the end tab which

connects it to the bellows set if you have or acquire one. It's an easy piece to lose and hard to

find, so you might ask the seller because they usually come with the rail. Good luck.

I use it as a focusing rail and the little piece that Scott spots as missing is irrelevant for that purpose.

Very well built and is extremely useful.
