Hi.
I'm interested in using this lense in a small telescope (https://cults3d.com/en/3d-model/gadget/the-micro-scope-build-pack) but I am very many decades behind in photography.
I need to know what I'm looking for, is it fixed or zoom, is it compatable with EF mounts?
Do they even exist now?
How would I know what the mount is? Is it written on the lense body?
Atb.
