My mom and dad keep their backyard well stocked with birdseed, bread scraps, discarded fruit, and so a lot of yard birds visit their property. I just happened to be there on New Years Day with my camera and 70-200 2.8L II. Not the best lens for birding but thought I would give it a shot. My shooting angle was restricted to peeping my lens out through a small opening in their patio door so not the best angles.
The real wonder is how much detail and sharpness I was able to preserve in cropping down so tight in post processing. Both the crops are about a 1000 pixel crop out of the middle of a 5DIII full frame.
All SOOC except for the crop.
1. Bluejay, full frame, ISO 320, f4, 1/320 shutter
2. Bluejay, cropped down. Would love to have gotten a better angle on this guy to eliminate the neighbor's shed from the background. But I was restricted to whatever view I could get by peaking my lens through a narrow opening in their patio door.
3. Mockingbird, full frame, ISO 320, f4, 1/320 shutter
4. Mockingbird, cropped down
