JJC EF-GFX100RF Series eyecup is specifically designed for the Fujifilm GFX100RF, crafted from premium soft silicone for comfortable use—even for eyeglass wearers, with no worry of scratching lenses. The aluminum alloy mounting frame enhances structural stability and durability, ensuring a secure and long-lasting fit that maintains a tight seal with the viewfinder during extended use. The ergonomically designed eyecup contours comfortably to the eye socket, effectively reducing eye strain during framing. It blocks stray light and studio glare for clearer composition while preventing dust, moisture, and accidental impacts from reaching the viewfinder. Featuring an extended, widened design, it minimizes nose contact with the LCD screen, even photographers with high nose bridges can shoot comfortably for extended periods without distraction. The eyecup installs via the camera’s strap lug while featuring an additional matching strap lug, which allows simultaneous use with shoulder straps for unimpeded framing and carrying. Additionally, it maintains full compatibility with the camera's eye sensor and touchscreen LCD functionality. Whether shooting horizontally or vertically, it provides a secure, comfortable fit against the eye for optimal shooting comfort.
