Slack Slough resides immediately beside HWY2(stupid busy road) in Red Deer, Alberta. It is home to an amazing amount of birdlife. I visited the slough this evening to take in the sights and sounds. Of course I dragged along my camera and telephoto lenses to see what I might capture. I got there kind of late so didn’t have a lot of time before the light was gone for the day. Using a Canon FD 800mm f/5.6 with an adapter to fit my Olympus E-M5, I ended up using only 1/80 sec. at ISO 800 when I finally packed it in as that is really starting to push the envelope of what can be done! This monster telephoto gives me the equivalent focal length lens as a 1600mm on a 35mm/full frame camera, or a 32x spotting scope. Obviously one must use a large and very sturdy tripod/head combo. In this case,for those that care, it consists of a set of Gitzo 3 Series carbon fibre legs and a Sachtler FSB8 fluid head.
All that said, here are a few images of some Lesser Yellowlegs (Tringa flavipes):
