High-performance zoom lens compatible with full-frame cameras, a 16-35mm model with an F2.8 aperture. - Model Name: FE 16-35mm F2.8 GM II - Mount Type: E-mount - Maximum Aperture: F2.8 - Lens Type: Zoom Lens - Full-frame Compatible: Yes Thank you for viewing. I purchased this new in February of this year and only used it indoors. It has been stored in a dry cabinet since then, but I will be selling it as I don't anticipate using it in the future. There is no dust or scratches, and it is in very beautiful condition, so please rest assured.
