Care Instructions
To maintain the exceptional optical performance of your Sigma Art lens, always keep a high-quality UV filter attached to protect the front element from scratches and dust. When shooting in inclement weather, wipe down the dust- and splash-proof barrel with a clean, dry microfibre cloth before storing it. Store the lens in a cool, dry environment, ideally in a dedicated camera bag or dry cabinet, to prevent fungal growth on the internal elements.
