This is a Micro Four Thirds lens. I purchased it used, and I think the condition is not bad. There is some dust, but it's at a level that doesn't affect the image quality. There is a general feeling of use. - Model Name: LEICA DG VARIO-ELMARIT 8-18mm F2.8-4.0 - Focal Length: 8-18mm - Maximum Aperture: F2.8-4.0 - Minimum Focusing Distance: 0.23m/0.75ft - Accessories: Lens hood, front/rear caps, box, instruction manual, etc. Thank you for looking.
