These include a focus mode switch for quick changes between manual and autofocus, an AFL button for locking focus, and an aperture ring for tactile exposure control. The aperture ring click switch allows for silent operation during video recording, while the aperture ring lock prevents unintended adjustments during shooting.Durability is a key feature of this lens, with a construction that is both dust and splash-proof, ensuring reliable performance even in challenging weather conditions. The thoughtful design extends to the included accessories, such as a lens cap tether to secure the cap, a protective pouch for safe transport, a 67mm filter kit to enhance image quality and protect the lens surface, a lens cleaning kit for maintenance, and a Corel PC software kit to expand post-processing capabilities.In summary, the SIGMA 35mm F1.4 DG DN Art lens is a high-quality, professional, durable, innovative, and versatile tool that stands out for its ability to capture stunning images with ease and precision.
