I have a Canon EOS RP that was purchased in 2019. I would like to use it to take pictures of wildlife from 50-100 yards away. What lens would work best for this? I am open to used. I also have very little knowledge about high end camera technology.
Sorry for the late answer.
A lens will give you about 10y of reach for every 100mm.
Canon has a 200mm-800mm zoom lens for your camera, that will give you the maximum amount of reach. However, the aperture is 6.3-9, which means it will really only be able to give you images during the day.
Lens:

https://amzn.to/3H2rWSqCanon also has a 600mm and 800mm that are f/11, which is pretty interesting. F/11 is not allowing much light in at all, but the lens is under $1000.

https://amzn.to/4mh2wzBThe most typical consumer lens is the 100-400mm at about $700. Again, most of these long reach lenses are not good for the evening - they really are daytime only.
