USED Pentax smc PENTAX-DA 15mmF4ED AL Limited

Despite being an ultra-wide-angle lens, it excellently corrects various aberrations, including distortion. Moreover, it's surprisingly compact and lightweight. This is a lens that allows you to fully enjoy the appeal of ultra-wide-angle, such as a sense of width and perspective.

• An ultra-wide-angle lens with a focal length equivalent to 23mm on a 35mm format, enabling unique expressive effects like emphasizing perspective and shooting with a deep depth of field, thus expanding photographic possibilities.
• Following the design concept of the Limited Lens series, it pursues further optimization for digital image quality, delivering sharp, high-contrast, clear images.
• High descriptive performance with excellent correction of various aberrations, including magnification chromatic aberration, and top-class distortion correction for an ultra-wide-angle lens.
• Overwhelmingly compact and lightweight design thanks to a newly developed optical system.
• Uses high-grade, machine-cut aluminum for the lens barrel, hood, and cap.
• By making the front of the lens a flat shape without a dome-shaped protrusion, it allows for the attachment of commercially available 49mm filters, including the circular polarizing filter frequently used in landscape photography.
• Built-in petal-shaped hood that is compact due to its slide-out, retractable design.
• Achieves a minimum focusing distance of 0.18m.
• Features the "Quick-Shift Focus System," allowing manual focus adjustment after autofocusing without any switching operation.
