I’ve been shooting BiF, namely puffins. They are small and shoot about like little bullets. My T7i and Tamron 100-400 struggle, i feel i follow them and say get an AF point on a wing or something with a decent DoF, but seems to miss focus most times. I appreciate this could be my technique, but i was wondering from a technology side, which would be the limitation in my setup?

Body or lens? Or both? I have a t7i and Tamron 100-400. Would using a Canon 100-400 L II autofocus better? Or do i need a 7dii or 1dx? Or both? My camera has no way to alter any AF settings in terms of sensitivity and things like the 80d allows.

please check my earlier photos at my flickr site.. Plenty of Good BIFS with the t7i.  90D better but not really that much

When I'm not playing birds, I'm shooting my accordion....or is it the other way around?
