Lens: Canon EF 500mm f4 L IS ii USM Purchase Date: At least a decade ago Condition: Great, just needs light cleaning

TL;DR: Have monster lens, going to rent a body to shoot with, would like ideas on what to shoot with a 500mm.

Story: Received this lens from an acquaintance whose estranged family member died. I got it because I’m the only camera person they know and because their family member was a piece of work whose stuff they don’t want around. I can do what I want with it but they asked if I sell it to throw them a few bucks.

Issue: Problem is I shoot Nikon with a D780 and only recently learned you can’t put an EF lens on an F body mount.

Solution: I plan to rent a canon body of similar quality to my D780 for a week, take a bunch of photos I’d otherwise not be able to, and consider if should keep the lens for infrequent use or sell it and split the cash with the acquaintance. (Renting because I don’t need another camera and I can use a better camera than I would buy)

Request: Let me know what are some cool shots I can take with a 500mm prime lens. Currently thinking about doing a great moonshot and photographing some eagles in the park nearby.

Side Note: The used electronic store I took this to offered $400 for it but I know they seriously lowball stuff. if I sell it I’ll take it to B&H in Manhattan as I’ve gotten good deals from them. (Only took it to the electronic shop so I could figure out if it’s still worked)
