Big Mike's
The Big Mike's High‑Power 420‑1600mm f/8.3 HD Manual Telephoto Zoom Lens is a budget‑oriented, manual‑focus super‑telephoto lens for Canon EF‑mount DSLRs, offering an extreme 420‑1600mm reach (with a 2× teleconverter) and a solid all‑metal construction. It targets static subjects such as the moon, distant wildlife, and basic astrophotography, but its heavy weight, manual focus and modest f/8.3‑f/8.9 aperture limit its versatility.

Expert Opinion
Professional reviewers acknowledge the lens's impressive metal construction and its unprecedented 1600 mm reach at a low price, calling it a potential game‑changer for static, long‑distance shooting. However, they uniformly criticize its heavy, unwieldy design, the lack of autofocus, the modest f/8.9 aperture that hampers low‑light work, and the inconsistent sharpness at the extreme end, with some even reporting outright build failures.
What Users Say
Everyday users love the solid feel and the ability to capture sharp moon and distant static shots, especially when mounted on a tripod. The recurring complaints focus on the lens’s weight, the difficulty of manual focusing on moving subjects, variable image quality at the longest focal lengths, and occasional quality‑control problems such as broken mount pieces.
Common Complaints
Weight and bulk, manual focus difficulty, inconsistent sharpness at 1600 mm, poor low‑light performance, and occasional mount breakage are the most frequently reported issues.
