Up for auction is a Sigma 10-20mm F4-5.6 EX DC lens for Canon AF mount. I recently purchased a 5D Mark IV and cannot use this lens with a full frame camera. There is minimal damage and is viewed on the top viewfinder which is pictured and is how I received it. It does not cause any issues with function or photo quality. It includes the original lens hood, belt holster, documentation, and packaging.
