I am looking to get into photography and have just purchased a Canon EOS R7 as my first "proper" camera. I did a lot of research beforehand and this seemed to be a solid first camera. Fortunately I was able to get a good deal on an unboxed/returned one. It was bundled with the RF-S 18-150mm lens and i'm therefore wondering whether the RF 50 lens would be a pointless addition or is it better for particular situations? Eventually, as I get better, i'd like to try out some wildlife photography and have been looking at the RF 100-400m and RF 600m lenses. Would either/both of these be a good option or are there better options? Thanks for any help/advice.
