Absolutely amazing,"

(NOTE - I mistakenly replied to joeblow, which made no sense; the reply should have been directed to 2dawgs, as he was the one who asked the question)

It was around 4:45 pm EST and pretty sunny, with some high clouds that diffused the sunlight just a bit. The sun was coming from just behind me. I used aperture priority (between 5.6 and 8) at ISO 640. I let the camera select the shutter speed, which was in the 1/1,000+ range at the start. Then, as the sun went down, and as the clouds got a bit thicker, the shutter speed dipped into the 1/500 range, making for blurry images. I went with aperture priority because I knew I had good light. In hindsight, as the light was diminishing I should have switched to shutter priority to keep it at least at 1/1,000. Live and learn.

I also used continuous focus tracking and the facial/eye portrait setting to aid in getting the eye to be the primary target in the image. I used the burst mode shutter control.

These were all shot with an Olympus OM-D EM-1 MK II with the 40-150mm f2.8 pro lens. Distance to birds was between 15' to 50'. The images here are cropped substantially.

I hope this helps.
