Working to catch wing blur with an otherwise sharp bird. Never see a hummingbird wing not blurred if it's flying. It's a fine line with the shutter speed.
I was doing a similar experiment last night with volleyball...unsuccessfully...probably need to keep at it, but I got frustrated and went back to 1/800 since I was just getting trash shots. I need to find the sweetspot that has the player sharp and the ball in motion. I think down to 1/400 or 1/500 might work after looking at what I was doing last night. 1/125 was too slow. Just trying to put some motion into it, but it is so chaotic and unplanned, random so it makes it really hard to do that. But for the rest of the games this year, I am going to experiment.
