E-mount lens accessory made by SIGMA, with USB cable, and box. - Brand: SIGMA - Compatibility: FOR CANON - Mount Type: E Mount - Accessories: USB cable - Box: Yes Full-frame DSLR, Mirrorless This is a converter that converts Canon EF mount to Sony E mount. I used Canon EF lenses on my SONY FX-3 and they worked without any problems. I am selling this because I no longer need the telephoto lens after purchasing the PXW-Z200. The product box and included cable are included. This is a used item. Please refrain from purchasing if you are sensitive to imperfections. Thank you. Thank you for viewing.
