Lens Overview — Opteka 28mm f/2.8

The Opteka 28mm f/2.8 is a manual-focus prime lens designed for mirrorless camera systems. Built around a fixed 28mm focal length, it sits comfortably in the standard range, making it a versatile option for everyday shooting scenarios including street photography, travel, and general-purpose use. With a maximum aperture of f/2.8, it offers a reasonable degree of light-gathering capability for a compact prime.

The lens accepts 49mm screw-in filters, giving photographers access to a wide range of filter options without adding significant bulk. Weighing just 140g, this is a notably lightweight optic that won't add strain during long shooting sessions or while traveling. Manual focus is the sole focusing method — there is no autofocus capability — which suits photographers who prefer deliberate, hands-on control over their focus point.

Image stabilization is not present in this lens. The lens is built for mirrorless camera systems, and the compact, lightweight form factor makes it a practical companion for photographers who prioritize portability without stepping away from a fixed focal length. The 49mm filter thread is a common size, keeping accessory costs manageable.
