This is a telephoto lens for the Micro Four Thirds mount. It allows for telephoto shooting up to 400mm in 35mm equivalent. Autofocus and image stabilization are working without issue (confirmed with my LUMIX G9 PRO). It is a used item, so there may be some dust, but there is no critical damage that affects operation. Includes the original lens hood, front and rear lens caps, and the original pouch. For those who purchase without a discount, I will include a Kenko lens filter. - Brand: LUMIX - Included items: Lens cap, lens pouch - Lens mount: Metal mount - Lens type: Zoom lens Thank you for viewing.
