Recently picked up a RX100 V off Facebook and as popular as this camera is I was pretty disappointed there were no affordable digiscoping adapters commercially available. So I decided to make my own.

The diameter of the Sony lens is 2.18” at the widest and my Meopta 80HD was 2.24”. With the dimensions so close I figured a cylinder shape would work and I would just add duct tape or something to make up the difference.

I used 0.080” Kydex from Amazon, like $16. Scored it with an Outdoors Edge into an appropriately sized rectangle. The length of one side was pi*diameter of the eye piece, and the width was the length of the camera lens fully extended plus however much overlap I wanted on the scope eyepiece.

Put it the piece in my oven at 360 F for a few minutes, pulled it out and wrapped it around a PVC coupling I had that was 2.22” in diameter. I put the coupling in the freezer and wrapped it in aluminum foil beforehand to prevent melting and encourage cooling of the Kydex. After it cooled I did some loose fitting and sanding and Dremeling to get it right. I use the front of the lens (not the glass) to index off the eye cup (also not the glass). Then to keep it secure I used some 1/16” and 1/8” shock cord, although I think 3/32” would be better for both.

I really like it, works well. Quick to deploy, secure. Safe, although I’d like to add a tether to the camera just in case. On all the way out zoom some vignetting but when zoomed almost all disappeared. 4K video so opportunity to crop. You should make one for yourself.

Killer! Thanks for sharing. Don't want to get banished, but I've struggled with the commercial adapters with my driod. They all work, but changing the case and wicked tight tolerances - just left it home. I've tried with some PVC couplings but all of them are a bit off. Never thought of using Kydex nor the shock cord. Thanks again!
