Aluminium 100mm Professional Rail Nodal Slide Metal Quick Release Clamp for Camera with Arca Swiss Compatible for Tripod Ballhead Quick Release

+ Well built. Strong, but relatively thin and light.+ All the features you need (a clamp, a dovetail, and two stopper screws on the bottom) and none that you don't.+ 140mm is just the right length for "ordinary" lenses (everything except ultra-wides and super-teles).+++ BONUS +++ The numbered scale puts zero at the camera end of the rail and increases as you move away from the camera. Hence, a bigger number means that the nodal point (diaphragm) is further way from the film plane (image sensor). Bingo! That's the way it's supposed to be. (Almost all the other Chinese rails get this backwards.)

This rail is very well made with good quality materials. It is very simple and does not have what you do not need. 140mm is also the most useful length for most middle and wide focal distance lenses. Longer slides (200mm) may block your lens field of view.Quality and construction of this slide approaches quality of stuff you can buy from RRS. I have tried (and returned) nodal slides from Neewer and their quality and construction cannot match this slide - ArcaSwiss clamp on those was really poorly made. The nodal distance on this slide is correctly measured from the camera clamp, on most Chinese rails it is measured from the other end of the rail for some unknown reason. This rail also has thinner profile than most Chinese ones.

I bought this for 2 uses. The first is to make my camera setups for macro photography easier. Once my tripod is set up I can move the camera forward and backwards, left and right using this device, an Arca Swiss mount plate, and a second Arca Swiss rail (as demonstrated in my last image). I also plan to use this to help me set weight and balance on my steadycams. Again - I can adjust the camera and lens position to get things in balance quickly and easily. Good solid build, all metal. I will likely order another one of these to have for b-roll cameras.

This functioned well and fit/finish were very good. However, it was too short for me to balance my full frame DSLR in a gimbal head. So I returned it and ordered a longer one.This was an excellent value compared to any established photography brand (RRS prices are insane—and yes, I have paid them and the quality is amazing). I don’t plan to use it a lot but expect that it would stand up to harsh use.

I needed this rail to use my standard lens on my camera with a "L" bracket on a Gimbal. The Gimbal head has the base facing forward so that it will accept a Large Telephoto lens which has a foot facing forward. In order to use the camera with the "L" that I normally use on a Ball Head I now mount the Modal Rail on the standard lens and it will fit my Gimbal.

For the $21.00 a great buy if you don't have an RRS BH-55 QR Lever head as it's not 100% tight but for any other head that used a turn lock this is a MUST BUY! What a bargain! Very high quality but not RRS quality BUT $120 less it's well worth it.The level is ok not as good as it should be bot again for $21 that's what the RRS bubble cost to make, well maybe not but my point if your looking for a pano rail this is it!Christopher

Quality is not far off from RRS. Not a fan of the bubble level. I think the part would look better without this minor functional feature.

This is a really nice slide especially considering the low cost. Of course it doesn't matter if you save money if the product is crap. This certainly isn't crap! Solid build, nice strong clamp, clearly marked. Compare it to ones that cost 10 times as much and you'll still be impressed.
