This is a 28mm wide-angle lens made by Soligor, with an FD mount. I purchased it over 10 years ago from a used camera store and primarily used it with a mount adapter on a digital SLR. The exterior has minor scratches and scuffs, showing signs of use. The lens has no mold or haze. When I bought it, there were marks from where mold had been removed near the rear lens element, but I haven't noticed any particular impact on the photos. The bokeh is soft when shooting wide open, making it a lens you'll want to use near its maximum aperture. Stopping down a bit results in sharper images. Photos 11 and 12 are sample images taken with a full-frame mirrorless camera using a mount adapter. Brand: Soligor Model Name: Wide-angle lens Filter Diameter: 58mm Accessories: Lens cap, rear cap
