Duplicate listing of the Sigma 12-24mm f/4.5-5.6 II — same lens as ID 3426.
The Sigma 12-24mm f/4.5-5.6 II DG HSM is a duplicate listing of the ultra-wide full-frame zoom described under ID 3426. At 12mm on full frame, it offers one of the widest rectilinear fields of view available in any interchangeable lens. The second-generation design improved coatings and sharpness over the groundbreaking original.
Optical quality is good with impressively controlled distortion for the extreme focal length. Sharpness is respectable in the centre and acceptable in the corners when stopped down. The 12mm wide end provides a dramatic 122-degree field of view. HSM motor provides fast, quiet autofocus. Flare can be an issue shooting into strong light sources.
Nikon F mount in this listing — also available in Canon EF. The bulbous front element prevents front filter use. Weight is approximately 670 grams. Build quality is solid. No image stabilisation. The later Sigma 12-24mm f/4 Art replaced this with significantly better optics but at higher cost and weight.
Available on the used market at reasonable prices. Check the front element for scratches — its exposed position makes it vulnerable. The Sigma 12-24mm f/4 Art is the clear upgrade. This version remains a capable, more affordable ultra-wide option for architecture, interiors, and landscape work.
