This is a bright, single-focus wide-angle lens for Micro Four Thirds. I am selling it because I don't use it very often. I've owned it for about 5 years and have stored it in a dehumidified storage box. Both the exterior and the lens appear to be in good condition with no noticeable scratches. It will be shipped with the front and rear caps, the original box, and the instruction manual. 【Product Overview】 ・Focal Length: 7.5mm F/2 ・Angle of View: 110 degrees ・Mount: Micro Four Thirds ・Lens Construction: 9 groups, 13 elements ・Aperture Blades: 7 blades, Filter Diameter: 46mm ・Minimum Focusing Distance: 12cm ・Size: 50 x 55mm ・Weight: Approximately 170g
