Focusing rails are essential accessories for macro photography, which requires precise distance modifications and a steady hand, as well as other situations where accurate camera positioning is crucial.
Two 6" rails allow movement in four directions, right, left, forward and backward. Mounts on, and accepts 1/4 thread screws, and it will fit most tripods and stands. Positive locking knobs assure rock-steady focus.
This excellent quality rail is for use with all digital and film SLR cameras and is compatible with most Canon, Nikon, Minolta and Pentax macro and EOS bellows, macro shot extension tubes, or macro lenses such as the Canon FD and FL
This is a generic focusing rail slider that is sold by numerous vendors at many websites under several different names. I think it emanates from Hong Kong. Who knows where they get them from.
I've used it a couple of times and I'm generally pleased so far. The materials look good and it feels solid.
A few observations:
1. It's pretty heavy. Shipping weight was supposedly 1 pound, but I think somebody rounded that off in the down direction. It feels heavier than that. It really needs a good tripod and it's not the kind of thing you want to carry around all the time.
2. The adjustments are not terribly fine. It's certainly no micrometer. I put a few drops of military grade weapons oil on the teeth to smooth things out, but that made little difference.
3. Attaching the camera is a bit difficult because the tripod screw nob is close to some of the other adjusting nobs. Quick release plates can help alleviate this problem, but that adds more weight and more things that can "wiggle" when taking photos. In closeups, that's really bad.
I took several pics of a small cactus flower about an inch in diameter using a small Nikon 50mm prime lens and a short extension tube. Working distance was about 3 inches from the flower. The rails help a lot with focus and framing, but a tiny rotation of the back and forth adjustment was enough to knock the camera completely out of focus. I used an old Vivitar tripod. Next time I'll use a much heavier Induro A313 tripod and a Manfrotto tilt head with the rail. That should allow use of larger lenses and result in sharper photos.
