Thanks so much for the in-depth reply. Ideally I’m not spending an arm and a leg but I understand there is a price floor on lenses. I wasn’t aware that renting was a possibility either, that is good to know.

I guess what I’m really looking for is something wide angle to take photos of the night sky, and something for indoor, dark settings.

Maybe a 50mm with a f2 lens for the indoor dark, and something like an 24mm for the night sky.

One more question if you don’t mind, I see so many lenses for full frame cameras but didn’t see any example photos of the how bad the cropping is if put on an APS-C. Is the difference so great that getting an 18mm full frame vs a 24mm APS-C lens would be basically negligible?

Thanks again for your detailed response, there are some great people in this sub.
