The Asahi Optical Co SMC Pentax-M 50mm f/1.7 is a compact and well-built prime lens, known for its sharpness, contrast, and rich colour rendition thanks to Pentax’s Super Multi-Coating (SMC) technology. Designed for Pentax K-mount cameras, its fast f/1.7 aperture excels in low light and creates beautiful bokeh, making it ideal for portraits, street photography, and everyday use. With precise manual focus, a smooth aperture ring, and solid metal construction, this lens offers a classic shooting experience while remaining lightweight and portable.
