Sigma
Pre-Owned - Sigma 17-70MM F/2.8-4 DC Macro OS for Canon.
The Sigma 17-70mm is a series of versatile, large-aperture standard zoom lenses designed for APS-C crop-sensor DSLR cameras. Known for combining optical performance with a compact design, it is a popular all-purpose or "walk-around" lens.
Key Features:
Compatibility: This lens is designed exclusively for cameras with APS-C sensors and is available in various mounts including Canon EF-S, Nikon F, and Sony A. Vignetting will occur if used on a full-frame camera.
Aperture: It features a bright, variable maximum aperture of f/2.8 at 17mm to f/4 at 70mm, which is faster than most standard kit lenses (typically f/3.5-5.6). This makes it more suitable for low-light situations and creating a pleasing background blur (bokeh).
Macro Capability: The lens offers good macro capabilities with a minimum focusing distance of approximately 8.7 inches (22 cm) and a maximum magnification ratio of up to 1:2.8, allowing for detailed close-up shots.
Image Stabilization (OS): Most versions (except for some Sony A and Pentax mounts) include Sigma's Optical Stabilizer (OS) function, which helps to minimize camera shake and allows for shooting at slower shutter speeds.
Autofocus (HSM): It incorporates a Hyper Sonic Motor (HSM) for quiet, fast, and accurate autofocusing.
