Hello, I’m ordering the R6 Mark II and I have access to a couple Canon EF lenses that I plan to use with the adapter. A couple zooms (28-105 and 18-55, both canon, but cheapest ones) I do have the sweet EF 300 2.8 for some distance, but I’m trying to decide what zoom or prime would be most useful for some photography, but mostly video. I work at a zoo specializing in alligators and crocodiles and our migratory bird season is outstanding for subjects close and far. The need for serious telephoto isn’t a big deal because I’m here 5 days a week and can get fairly close to a lot of subjects, even crocodiles and so forth. So I’m able to buy one decent lens right now, but don’t really know what’s most useful. Zooms like 24-70, or 70-200, or some mid range prime lens? Any advice is welcome as I’m a novice. Thanks!
