Some shots I took of sparrows in our garden - we have a feeder set up with bamboo as a backdrop about 10 feet behind, camera set on a tripod and pre-focused
7D2 with 100-400Mkii + 1.4xtc, ISO1600, f9 and 1/4000
Mikehit - great shots ... I read where some folks complain about the 7D2 occasionally, but I sure find no fault with it. Proof right there in your backyard how well it performs ...
