The cutting-edge design incorporates a large prism with minimal light attenuation, resulting in a crystal-clear and vibrant viewfinder image. Say goodbye to visual variations caused by different eye positions, as the INON viewfinder ensures consistent brightness and clarity, even in the corners.

Experience a whole new level of visual immersion with Inon's optically designed viewfinder, specifically tailored for electrical viewfinders (EVFs) in full-size DSLR cameras. Their advanced viewfinder offers the same magnification as your camera's viewfinder (1.0x), allowing you to capture the entire scene with precision. Say goodbye to limitations and enjoy an extended eye-point of 60 mm/2.4 in., eliminating vignetting, even when using a mask.

Created from high-quality optical components that are carefully housed in a compact, lightweight, and durable body. Constructed from a corrosion-resistant aluminum alloy and reinforced with fiber-reinforced plastic (FRP), our viewfinder guarantees longevity and reliability.
