Wow, you're getting great results with a Canon Rebel! If you upgraded to a 90D you'd get a much faster AF system as well as a substantial boost in resolution. And you'd also get to keep all your glass. Just my $.02.Very nice shooting, Mitch. It's not easy capturing bif. I saw an osprey chasing a crow away from its nest the other day but my crappy Canon T6 wouldn't focus on it. I reeeally need a new camera with animal eye detection and a faster zoom lens wouldn't hurt, either.
