Here are my first photos with a new Olympus 300mm f4 Pro lens (effective 600mm) and the EM-1 Mk II camera.
Today the light was a little better and I found some subjects in two birding areas that were sheltered from the cold and gusting west wind.
The first 5 images are from today: 3/9/10, and were made at ISO 320. The two images of the Mallards are of the greater size and cropped the least, as the birds were closer and are of course larger than the mergansers and the grebe.
The other 7 images were shot on March 6, mostly at ISO 1600. All images are cropped. All images were made hand-held, camera set on aperture-preferred mode, with pattern metering. Appropriate exposure compensation was used for the lighting conditions encountered.
