Product Name: SIGMA 28-70mm F2.8 DG DN | Contemporary Mount: Leica L-mount (SIGMA, LUMIX common) Purchase Date: December 2023 (new purchase, warranty expired) Included Items: Lens body, genuine hood, instruction manual, box Scratches and Stains: No noticeable scratches or stains. Excellent condition. Operational Performance: Operation confirmed. No fogging inside the lens. Purchased online from SIGMA in December 2023. Although the warranty has expired, it functions normally, and there are no scratches or stains that would hinder shooting; it is in excellent condition. This lens is very compact while maintaining F2.8 throughout the entire zoom range, achieving both ease of use and high image quality. I am selling it because I want a telephoto lens, but it is highly recommended for those who want to take high-quality photos in the standard range! (Note) Although it is listed as a Sigma SA mount due to Mercari's system, it is actually an L-mount.
