Thank you for viewing! This is the Panasonic LUMIX G 20mm F1.7 ASPH H-H020. I have managed this lens in an environment free of tobacco and pets. I am selling it because I sold my Micro Four Thirds camera and no longer have a use for it. This is a popular pancake (prime) lens. With a wide open aperture of F1.7, you can take advantage of beautiful bokeh, making it perfect for table-top photography. Stopping down the aperture allows for sharp images that you can't get with a zoom lens. It's small and easy to handle, making it ideal for outings and travel! Includes lens filter and lens pouch. ★ Optics The lens has no scratches or cloudiness and can take clear photos. There is a very small amount of dust inside, but it does not affect the photos. Thank you for your consideration. Please note that this is a used item, so to prevent swapping, I request no returns or exchanges.
