Since the subject of binocular service has come up, has anyone sent optics
back to Canon for repair?

I have their 15 x 50 image-stabilized binocs, purchased at Captain's
Nautical in 2001. I've been super-happy with them. Some time in the last
year, I noticed that the image in the right barrel doesn't seem as sharp as
the left. It's not my eye, because flipping them upside down moves the
imperfection to the left eye. I don't remember dropping or banging them,
but I suspect something has shifted out of alignment in the optics. I have
been procrastinating about sending them for service since the problem is
not extreme.
