The RED CAM Round Viewfinder Eyecushion, in jaguar Ultrasuede, is the standard RED-compatible version from Bluestar. At 2.7" in diameter, it fits the RED DSMC2 OLED EVF eyecup, RED BOMB EVF eyecup, and all similar-sized eyecups from RED and other brands. It's designed to attach to the eyecup easily and stay on securely.
This Ultrasuede version is made of 100% non-woven material consisting of intertwined, brushed, ultra-fine fiber strands. It provides a high level of softness and a superior moisture absorption rate, and it can be used in any climate. The RED CAM Round Eyecushion is also known to be compatible with the Canon VIXIA HFG40, XA30, and XA35 camera eyecups, as well as all Panavision and similar eyecups. It also fits the C100/C200/C300/C500 viewfinder that doesn't use a large rubber eyecup.
