Manual-focus super-telephoto zoom covering 420-800mm with an F/8.3-16 aperture range, built for precise long-range shooting. The lens uses a T/T2-style mount and is offered with an adapter ring for use on Canon M series bodies (replacement fit for Canon M M2 M3 M5 M6 Mark II M10 M50 M100 M200). The unit is also described as a T mount lens with RF mount adapter ring for flexible mounting options. Optical construction: 4 elements arranged in 2 groups, made from premium optical glass to ensure high light transmittance and accurate color. An ultra multi-coating reduces flare and ghosting for clearer, more vivid images. Mechanical features: solid all-metal housing for durability, plus a lock mechanism to secure the lens in position for stable, precise operation. The base includes a 1/4 screw thread for mounting on tripods or monopods; the base ring rotates to allow fast, convenient installation.
