Lens Overview — Tokina 300mm f/7.1 Pro Reflex MF

The Tokina SZ 300mm f/7.1 Pro Reflex MF is a compact prime telephoto lens built for mirrorless camera systems. With a fixed focal length of 300mm and a maximum aperture of f/7.1, it is designed specifically for APS-C format sensors. The lens is available in four mount options — Sony E, Canon RF, Nikon Z, and Fujifilm X — making it a versatile choice across major mirrorless platforms.

At just 235g, it is notably lightweight for a 300mm telephoto, which makes it an appealing option for photographers who prioritize portability when shooting subjects at distance. Focus is entirely manual, with no autofocus capability, so users who rely on phase-detect or contrast-based AF will need to adapt their workflow accordingly. There is no built-in image stabilization, so shooters will need to rely on in-body stabilization if their camera supports it.

The 67mm filter thread is a standard size, making compatible accessories easy to source. This is a prime lens with no zoom range — what you see at 300mm is what you get — which encourages deliberate composition and precise subject framing.

Key Features — Tokina 300mm f/7.1 Pro Reflex MF

300mm Reflex Design: Uses a mirror (catadioptric) optical construction to achieve 300mm telephoto reach in an unusually short, compact barrel.

Exceptionally Lightweight Build: Weighs just 235g, making it one of the lightest 300mm telephoto options available for mirrorless shooters.

f/7.1 Maximum Aperture: Fixed aperture of f/7.1 is typical of reflex lens designs and requires adequate light or higher ISO settings for hand-held use.

APS-C Format Coverage: Designed for APS-C sensors, delivering an effective field of view equivalent to approximately 450mm on a full-frame camera.

Four-Mount Compatibility: Available in Sony E, Canon RF, Nikon Z, and Fujifilm X mounts, covering the major APS-C mirrorless platforms.

Manual Focus Only: No autofocus motor is included, so precise subject acquisition relies entirely on the photographer's manual focus technique.
