Camera body is disgusting. These binoculars are not cheap and work well except for this problem which makes them unusable. This is a manufacturer's defect and in my opinion, Canon should compensate the customer.
These binoculars are about 10 years old, very lightly used and always stored in the case. I've had lots of binoculars and cameras over the years and never had this problem. Will probably go with Nikon this time.
