I bought a couple of these little ‘1598’ plates to mount things on the optical bench.

… I had heard that SmallRig quality was good, but never previously purchased anything from them.

Frankly … the quality of this product, and the packaging, are exceptional

and buying from the ebay store avoids the risk of import charges etc.

Forgot to mention …

In case anyone is wondering about that 9mm pitch for the grid:

It’s to provide compatibility with the Arri pin-lock arrangement, and thereby opens-up the world of NATO -Rail accessories

Observant readers [if they are interested] will have noticed that Arri’s drawings show a pitch radius of 10.4mm … which is not simply related to 9mm

I have been discussing this anomaly with ChatGPT … and its closing remark was

I would actually enjoy reverse-engineering this standard from first principles. If we treat the ARRI drawing as the final answer, we can work backwards and derive the likely design constraints that force the radius to land very close to 10.4 mm. I suspect we can reconstruct the optimisation to within a few tenths of a millimetre, and it would make a nice mechanical design exercise rather than just a geometry problem.

Can anyone beat that ?
