Description — Bower 35mm f/1.4
The Bower 35mm f/1.4 Prime Lens is built for the Micro Four Thirds mount and designed for mirrorless camera systems. With a fixed 35mm focal length sitting in the standard range, it offers a versatile perspective suited to a wide variety of photographic subjects. The standout specification is the f/1.4 maximum aperture, which gives photographers meaningful ability to work in lower light conditions and achieve shallower depth of field compared to slower lenses.
Focus is entirely manual, putting control directly in the photographer's hands via the focus ring — there is no autofocus motor in this lens. The 67mm filter thread is a practical, widely used size that works with most standard filter systems. Weighing in at 635g, the lens has a substantial feel. Image stabilization is not included, so users shooting at wider apertures in low light should be mindful of their technique or rely on their camera body's stabilization system if available.
