I was studying my camera a couple of days ago when I noticed a hummingbird at the feeders outside the dining room window. Here are three shots. The first without flash. The other two are with flash, which of course reflected off the window. These have been cropped, but not otherwise processed. The ISO was 800 because I didn't have time to change the settings from the night before.
1- 300 mm., f/5.6, 1/2000 sec., ISO 800
2- 300 mm., f/5.6, 1/200 sec., flash, ISO 800
3 - 300 mm., f/5.6, 1/200 sec., flash, ISO 800
