OM SYSTEMS EE-1 DOT SIGHT OM, V335920BW000

Product Description:

The OM SYSTEM EE-1 Dot Sight is a hot shoe-mounted external aiming accessory that solves one of the most frustrating challenges in wildlife and sports photography — finding and tracking fast-moving subjects through a super-telephoto lens. When you're shooting at 300mm, 400mm, or 600mm, even a tiny movement of the camera sends your subject flying out of the frame. The EE-1's red dot reticle gives you a wide-angle aiming point above your viewfinder, letting you track a bird in flight, a sprinting athlete, or a darting animal with both eyes open, then drop to the viewfinder for the shot — knowing your subject is already centered in the frame.

The concept is borrowed from the firearms world, where reflex sights have been used for decades to acquire moving targets quickly. The EE-1 applies the same principle to photography: mount it on your camera's hot shoe, calibrate the red dot to your lens's center point using the two adjustment thumb wheels (horizontal and vertical), and you have a heads-up aiming reference that works at any distance. Keep both eyes open, place the red dot on your subject, and the moment you look through the viewfinder, your subject is there — framed and ready to shoot. Photographers who have struggled for years to consistently find birds in flight at 400mm+ report dramatic improvement in their "hit rate" from the very first outing.

The adjustable red dot reticle offers variable brightness for visibility in all lighting conditions — from bright midday sun to dim dawn and dusk sessions when wildlife is most active. The horizontal and vertical position adjustments are made via precision thumb wheels that hold their calibration firmly once set. Users report that the EE-1 typically stays calibrated across a range of focal lengths (300mm–600mm) without needing readjustment, though recalibrating for a specific focal length takes only seconds.

The EE-1 attaches to any camera's standard hot shoe and features a slide lever mechanism for quick deployment — flip it open when you need it, close it flat when you don't. The construction features metal internal struts and base with a dustproof and splashproof exterior, making it durable enough for field use in rain, dust, and the unpredictable conditions that wildlife photographers routinely encounter. A dedicated thumb wheel on the hot shoe foot tightens the mount securely to prevent the sight from being knocked loose during active shooting. At just 2.5 ounces, the EE-1 adds virtually no weight to your camera setup. Powered by a single CR2032 lithium coin battery (included) that provides extended battery life across many sessions. Includes a soft protective case for storage and transport. Compatible with any camera featuring a standard hot shoe — OM System, Olympus, Sony, Canon, Nikon, Fujifilm, Panasonic, and more.
