Preowned Sigma 16 28 mm f2.8 DG DN Sony Mount

Focal Length & Aperture: Provides a versatile 16-28mm focal length range with a constant f/2.8 maximum aperture, making it great for low-light photography, astrophotography, and controlling depth of field.

Optical Design: Features a complex optical construction with multiple FLD and aspherical elements to ensure sharp, high-resolution images from corner to corner and minimize aberrations.

Autofocus (AF) System: Utilizes a quiet and precise stepping motor, making it well-suited for both still photography and video recording. The internal focus and zoom mechanism prevents the lens from changing length during operation.

Physical Design:

• Part of Sigma's "Contemporary" line, it is designed for a balance of performance and portability.

• Features an internal zoom mechanism, which keeps the lens length and balance point constant, making it ideal for gimbal use and video.

• The lens accepts a front 72mm filter, which is a significant advantage for landscape photographers.

• Built with a dust- and splash-resistant structure for use in various conditions.

Best for: A go-to lens for photographers and videographers who need a high-quality, lightweight, and compact ultra-wide zoom for landscapes, travel, vlogging, and architectural photography.
