Samyang SAMYANG AF 24mm F2.8 FE Thank you for viewing. I purchased this on Yahoo Auctions. This is a convenient single-focus lens that can be used on full-frame cameras at 24mm, and on Super 35mm cameras at the equivalent of 36mm. The exterior is fairly clean, but since it's used, there are some minor scratches and signs of use. There is some dust on the lens. I don't see any mold, at least to the untrained eye.
