There were countless egrets and ducks ever-present but the scene was dominated by a large osprey in a tree, the stately sea eagle the apparent king of the entire domain.

Because the Bigma is a full frame lens on the APS sensor on my Nikon d-7000dx rig, all millimeter focal ranges actually increase by fifty percent so 500mm is in reality 750mm.

The lens likes light, lots of it. I pushed the iso and the shutter speed. I usually shoot aperture priority but found that shutter priority was better for this lens, anything as slow as 1/250th had problems.
High speed means noise but there are ways of dealing with noise. This lens is a F4.5, the last version was 4.0, but I have to assume that there was a good reason for the switch.
