This is an ultra-wide-angle zoom lens for the EOS M, equipped with "Dynamic IS," an effective image stabilization function for shooting videos while walking, etc. I purchased this new previously, but I am selling it now to organize my belongings. This lens is highly regarded among EF-M lenses for its image quality, with a minimum focusing distance of 0.15m and a maximum magnification of 0.3x at the telephoto end, allowing for close-up shots of subjects. The exterior appears to be in beautiful condition without any noticeable scratches. The optics are free of mold and fogging, but there is some dust inside that does not affect the image quality. The operation is good, including autofocus, aperture operation, and zoom operation. The 13th and 14th photos are sample shots taken with this lens. Included accessories are lens caps (F, R), a protective filter, and a lens hood. Here is an excerpt of the specifications: Compatible Mount: Canon EF-M mount Lens Type: Ultra-wide-angle zoom lens Focal Length: 11-22 mm Minimum Focusing Distance: 0.15m Maximum Magnification: 0.3x Maximum Aperture: F4-5.6 Image Stabilization: Yes Filter Diameter: 55 mm Maximum Diameter x Length: 60.9 x 58.2 mm Weight: 220 g
