Benoison
The Benoison 420‑800mm is a manual‑focus, all‑metal telephoto lens for Nikon DSLR bodies that offers extreme reach (up to ~1200mm equivalent on APS‑C) at a budget price. It delivers decent center sharpness and smooth bokeh on three‑dimensional subjects but lacks autofocus, image stabilization, and has a slow variable aperture.

Expert Opinion
Professional reviewers view the Benoison 420‑800mm as a niche, budget‑oriented super‑telephoto tool best suited for mirrorless or adapted DSLR setups that can provide focus‑peaking and IBIS. They commend its solid metal build and ability to render smooth bokeh on close‑up subjects, but repeatedly criticize its lack of stabilization, manual‑focus only operation, slow aperture, and pronounced optical flaws such as field curvature and edge softness, making it unsuitable for serious professional work.
What Users Say
Everyday users appreciate the lens’s extreme reach and sturdy construction, often noting that it delivers decent center sharpness when mounted on a tripod and that the included case and cloth add value. However, the community consistently laments the heavy weight, the difficulty of manual focusing, the slow f/16 aperture, and the soft corners and chromatic aberration that require post‑processing, leading many to label it a hobbyist‑only gadget.
Common Complaints
Blur from camera shake without stabilization, difficulty achieving accurate manual focus, slow f/16 aperture limiting low‑light use, heavy and cumbersome handling, soft corners and chromatic aberration, and field curvature ruining flat‑scene rendering.
What People Are Saying
“Impressive reach and bokeh for price”
“"Not bad" sharpness if focus nailed on tripod (e.g., flowers at 800mm comparable casually to premium lenses at shorter FL)”
