The Round Ultra Small Viewfinder Eyecushion, in orange Ultrasuede, from Bluestar, is designed to fit securely over the eyecups of many compact DSLR and mirrorless cameras. It's made with thicker foam than that of standard Bluestar eyecushions to allow for better handling of the compact cameras. The eyecups of these cameras usually don't stick out very far, so the extra thickness is needed to provide more cushioning.
The inside diameter of this eyecushion is 1.25" and the outside diameter is 2.4". Compatible eyecups include that of the Panasonic GH5, the Olympus EP-2 oversized eyecup, and the Nikon rubber eyecup for the DK-8, DK-19, D5, D4S, D4, D3X, D3S, D3, D2H, D2X, D2Xs, D2Hs, D850, D810A, D810, D800E, D800, DF, D700, and D500 cameras. 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.
