Thanks for sharing your shots, guys. Went out to Bombay Hook Wildlife Refuge this morning to try out the 200-600, some of these images are heavily cropped, even with the 1.4 TC. With the TC the A7RIII is a bit too slow to acquire flying targets. Of course, operator may be blamed in most circumstances. I am not really a birder like some of you folks here. Will be interesting to see how the lens work with the A7RIV.
