In this video I’m back out at Harrison Bay State Park doing more winter bird photography, but this time I kept it super simple: Canon EOS R7 paired with the ultra-budget, ultra-light, ultra-small Canon RF 100-400. I wanted to see how much real-world bird work you can get done with a setup that doesn’t break your back or your wallet—and honestly, this lens punches way above its weight (and price), especially on the R7. The big takeaway is that the R7 + RF 100-400 combo is a legit field kit when you’re walking around a park, reacting to birds as they pop up, and trying to stay mobile. On the R7, that 100-400 turns into a very “bird-friendly” reach, and the whole setup stays small enough that you actually want to carry it. If you’re curious whether a budget Canon RF telephoto zoom can still deliver for birds in the real world, this is exactly the kind of outing that answers it.
