The lens hood for my Canon 100-400mm II lens has developed an annoying problem. The side window (for filter adjustment) frequently pops open for no apparent reason allowing in stray light. Other than taping it shut "permanently", does anyone have suggestions about how to solve this issue.
Alternatively is the another lens hood I could purchase that would fit my lens? I never use the window so that is not a requirement
