This is a standard zoom lens released in 1987. It was originally released for early autofocus cameras like the EOS 620, but it can still be used with current digital SLR cameras. It features a glass molded aspherical lens, and I think the image quality at the edges of the frame is quite good. It also has a macro mechanism that allows for close-up shooting up to 0.39m throughout the entire zoom range, so although it's an old lens, I think it's a convenient lens. I purchased this at a used camera store a few years ago and am selling it to clear out my collection. The exterior is in good condition with no noticeable scratches. The lens has no mold or fogging, but there is some dust inside that doesn't affect the photos. Autofocus and aperture operation are good. Photos 11 and 12 are samples taken with this lens mounted on a full-frame mirrorless camera via a mount adapter. Included accessories are lens caps (F, R). Here is an excerpt of the specifications: Aperture blades: 5 Minimum aperture: 29 Minimum focusing distance (m): 0.39 Maximum magnification (x): 0.22 Filter diameter (mm): 52 Maximum diameter x length (mm) x (mm): 70 x 74.8 Weight (g): 300 Size...
