- When does Sigma run sales?
- Sigma discounts cluster around Black Friday, the winter holidays and occasional spring promotions, and retailers like B&H and Adorama often cut prices independently of Sigma. There are no live deals on this page right now, so check back around those periods.
- Where is Sigma cheapest?
- US prices are usually close across authorized dealers such as B&H, Adorama and Amazon, because Sigma enforces minimum advertised pricing. The bigger differences come from bundled extras, sales tax and occasional instant rebates rather than the sticker price.
- What are Sigma's best lenses?
- The Art primes and fast zooms get the most attention, particularly the 35mm f/1.4 DG DN Art and the 28-45mm f/1.8 DG DN Art for full-frame E-mount. For APS-C, the 18-50mm f/2.8 DC DN Contemporary is popular for its small size and constant aperture.
- What is Sigma's return policy?
- Sigma does not sell direct to US shoppers, so returns go through the retailer you bought from, and each store sets its own window and restocking terms. Sigma's own warranty covers defects, typically for four years in the US for lenses, but not change-of-mind returns.
- Are Sigma lenses compatible with Sony bodies?
- Yes. The DG DN and DC DN lenses listed here are made for Sony E-mount and support autofocus, in-body stabilization and in-camera lens corrections on current Alpha bodies. Check the mount in the product name, since Sigma also sells the same optics in L-Mount and other fittings.
