Eyecups are the small rubber or plastic piece around a camera's viewfinder eyepiece: replacement or upgraded eyecups that seal out stray light and cushion the eye against the viewfinder during extended shooting. Where the original eyecup has worn, cracked, or gone missing, this is the small part that restores comfortable, glare-free viewfinder use.
Eyecups are camera-model-specific - order by the exact camera, since eyepiece shape and mounting method differ across manufacturers and even across a single manufacturer's camera generations. Larger or extended eyecups are worth considering for eyeglass wearers or anyone shooting for long stretches, since comfort and light-sealing both improve with a properly fitted cup. These are inexpensive, easily worn parts - keep a spare on hand for any camera in frequent field use. COLAMCO supplies camera eyecups for the photo and video programs business, government, and education organizations run.
