SIGMA 50mm F1.4 DG HSM prime lens. This is one of my favorite lenses, but I'm selling it with a heavy heart due to financial difficulties. It has a sharp image, which is typical of Sigma lenses, and sharper than the original lenses. I think the exterior and the lens are relatively clean. Since it's an older lens, there might be some dust or slight haze that doesn't affect the image quality. The operation seems to be fine. It comes with the original box. Thank you. The mount is Canon EF mount. Please comment if you need more detailed explanations or photos. No returns or exchanges. - Model Name: 50mm F1.4 DG HSM - Brand: SIGMA - Lens Type: Prime lens - Maximum Aperture: F1.4 - Mount Type: Metal mount Thank you for viewing.
