Spring Birds, D7100 + Sigma 50-500
The snow in Denver melted and the skies were a brilliant blue yesterday. Went to Lowery Wetland Park to see what I could photograph. Tried the 1.3x crop mode for the first time.
composition is good but the images do appear too soft. The last two aren't bad. is the lens OS and if so make sure it is on. if the lens is not OS then you really want to work on stance. at 500mm and assuming a right handed shooter i would grab a tree or other solid object with my left hand and rest the far end of the lens in the crook between my hand and the tree for some stability.
i might also turn the EV down a third or half stop.
