Thanks Connie. It is funny though with a long lens. Those of us with them take the focal length for granted. I felt lucky these mergansers were close to shore. Otherwise, I would have thought they were too far away to shoot.These are so nice, Allan! A couple of years ago was the first time I had seen Hooded Mergansers on our lake and was fascinated by them.....they returned last winter and I am hoping that they will show up here again this winter as well. With that long lens and TC you've sure got the right gear to get up close to these guys!
