f/6.3 Maximum Aperture: Moderate maximum aperture at this focal length, best suited to well-lit outdoor shooting conditions.
ED Glass Element: Extra-low dispersion glass reduces chromatic aberration, helping maintain edge sharpness and color accuracy across the frame.

Description — Rokinon 300mm f/6.3
The Rokinon 300mm f/6.3 ED UMC CS is a 300mm telephoto prime built for Sony E mount mirrorless cameras with APS-C sensors. Weighing in at just 318g, it offers a lightweight option for photographers seeking telephoto reach without the bulk typically associated with long lenses. The lens operates at a fixed maximum aperture of f/6.3 and is focused entirely manually — there is no autofocus system, so precise focus control rests with the photographer using in-camera tools.
A 58mm filter thread keeps compatible accessories affordable and widely available. With no image stabilization on board, shooting handheld at this focal length requires careful technique or support from a tripod or in-body stabilization if your camera offers it. This is a prime lens with no zoom range, delivering a single focal length for a focused, deliberate shooting experience.
It fits neatly into the Sony mirrorless ecosystem, making it a compact telephoto choice for APS-C Sony shooters.
