The Oval Ultra Small Viewfinder Eyecushion in purple fleece, from Bluestar, features outside dimensions of 3.3 x 2.6" to securely fit over many common external and built-in viewfinders. These include the Hoodman Hoodeye, JJC Oval Shape EyeShade, JJC Viewfinder, Bolex H16, and the viewfinder of the Panasonic GH5 with a compatible oval eyecup similar to the Hoodeye. This fleece version is made of 100% synthetic material and provides a high level of softness and comfort for cold weather while enhancing light blockage. The fluffy feel reduces the rate of heat transfer, making the material feel warmer in cold conditions.
