## Features

- 【Important Usage Notes】⚠ This is a fully manual lens with no electronic contacts. After attaching the lens, switch your camera to ​Manual (M) mode​ to avoid "no lens" errors.

- 【Super Telephoto Zoom Performance】A specialised full-frame zoom lens with a adapter ring. Features include precise manual focusing with a large focus ring, internal focus mechanism, and UMC multi-coating to reduce flare and aberrations.
