Simple question,
What is the cheapest and the most compact way to attach my samyang lens to star adventurer 2i?
Ive seen all those 3d printed mounts but they seem really overpriced and bulky.
Some kind of ring would be ideal.
I tried using Nikon 70-200 ring but it didnt work out, diameter turned out a bigger than the lens itself.
It fits on the small portion before F adjuster but the ring after that is way too small.
Any suggestions?
