Hello, I am selling the following items: - Sigma Art 35mm f1.4 lens in Canon EF mount - Sigma USB Dock for EF mount - 67mm diameter Tiffen UV filter The lens has been optically calibrated and updated with the latest firmware using the Sigma USB Dock. The original lens box is also included. This is a used lens in excellent condition. It is with regret that I am parting with it to prioritize the use of a zoom lens. The quality of its materials, sharpness, and wide aperture are notable features that make the Sigma Art series a benchmark for many photographers and videographers.
