No hissing! I only wish I had brought my 300mm lens with me instead of the 200mm lens I had. The 300 is a Canon IS lens, the 200 is an low priced lens I got that came with the camera and at a full 200 the quality is not that good. The 300 is outstanding at the long setting.
This is the second time I've seen otters at this lake. I have photo's of them, but will take some digging to find them.
