Feature: 1. Auto Focus Zoom Lens: The 12‑35mm F2.8‑4 lens features automatic standard focus and a zoom range of 12‑35mm (equivalent to 24‑70mm in 35mm format), covering wide angle, standard, and medium telephoto shooting, with versatile applications. 2. Wide Angle: This lens is not only suitable for portrait and landscape photography, but also excels in low light conditions with its F2.8 aperture at the wide angle end. It allows for easy capturing of night scenes, starry skies, and other large scale subjects in challenging lighting situations. 3. Super Macro Photography: With its incredible super macro (SCU) functionality at the wide angle end (12mm), the lens offers a closest focusing distance almost touching the front of the lens and a magnification ratio of 0.5x. This makes capturing details of jewelry, flowers, insects, and other small subjects simple, enabling you to explore the wonders of the micro world. 4. Internal Zoom Structure: The lens does not require an extending barrel when switching between wide angle and telephoto ends. This not only ensures good sealing performance, but also reduces the overall length of the lens at the telephoto end. The lens mount is equipped with a rubber seal and the lens structure is protected, dustproof and splash resistant. 5. Silent Motor: The lens is equipped with a quiet and accurate stepping motor (DSM, STM) for fast and accurate autofocus, making it suitable for both photography and short film recording.
