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.

    So, it looks like they’ve designed a 3D printed camera body, that takes EF lenses, and they use a raspberry pi sensor to capture the image.

    The lens they’re using is a Samyang 300mm f/6.3 reflex lens.

    Like all mirror lenses, it will be fixed aperture, and manual focus with no zoom (Yes I know, someone somewhere built an autofocus reflex).

    I think, if you’re looking at buying this lens, you need to rely on the seller telling you what mount it has, which can is very unhelpful if you’re buying used. Keep in mind that this lens won’t have any electrical contacts like most modern lenses do.

    So, you’re looking for an EF mount right? Is that what your camera takes? Because it’s available to fit Canon, Fujifilm, Sony and Micro Four Thirds mirrorless cameras.
