GM-MP1 4-Way Macro Focusing Rail

I think this is pretty good, It's solid, metal, and nicely made. I used it today for taking photos of bees in a flower. It's much easier to use this than moving the legs of the tripod lol. I ordered it last night with amazon prime and it arrived today, a sunday, free postage. Can't complain really. I'm using 68mm of extension tubes and an old olympus 85mm manual lens on my Fufifilm XT4.

After replacing my old bridge camera, I replaced old equipment. I owned a 4-way focusing rail, but it wasn't very well-built. There was no way it was going to have the accuracy or build quality for my new Panasonic FZ2500, a rather weighty camera, weighing over 2 pounds. I chose the Neewer, after buying a very nice Neewer carbon fiber tripod on Amazon. Neewer has a good reputation for quality, especially given the mid level price point. I looked at a few other types of focusing rails, but I really need the 4-way to do supermacros photography, like the snowflakes. I've never wanted to get back into carrying lenses, etc, so after 35mm, I simply decided on bridge cameras. I've photographed microscope slides with my bridge camera. I use a Raynox 250 super macros lens that I bought several years ago from Amazon. This requires the lens to be extended with the Raynox attached, to achieve super macros. Sharp focus is achieved by moving the entire camera back and forth, with a correction in framing by moving right/left. The 4-way focusing rail that I had, shifted when adjusting. The Neewer is rock steady. It doesn't use a worm gear (which can introduce backlash). Both axis are moved by rack and pinion mechanism. When switching to the opposite direction, there is less than 1mm of a turn of the focusing knobs before its engaged. You'd never notice it unless you were testing for it. The motion in all 4 directions is extraordinary smooth. Focusing tension is adjustable by smaller knobs. The focuser comes equipped with a Swiss Arca quick release plate with camera mount. I've got the Arca plate from the Innorel F20 pan/tilt head on the camera (another excellent piece of equipment that I bought on Amazon), which fit the focuser nicely. The mount clipped well, and very securely, holding the camera firmly in place. As a astronomer, I've used and worked on many telescopes, most with a rack and pinion focuser. I'll see how much vibration is introduced by using the focusing rail. I may outfit the focuser knob with a hands off, powered focusing adapter that fits over the knob. Addressing a complaint I've seen: For under $100, the Neewer 4-way rail is an excellent piece of equipment. I can't see where it would be improved. I think I saw a complaint or two about wobble in the rails. I have to believe this was from loosing the focusing adjustment too much. If you loosen the tension too much, you can indeed wiggle the rails. This is the same problem that you will have with any rack and pinion system, it's not a defect in materials or workmanship. I have a $500 aftermarket telescope focuser which will do the same thing. The secret is to maintain proper and enough tension, while ensuring smooth movement. When properly adjusted, there is no wobble or unwanted rail movement.

Good precision and easy to use. A good investment!
