Thank you for viewing. I am interested in old digital cameras and enjoy buying various used items, taking photos, and also doing repairs and maintenance. I would like to sell some items because my collection has grown too large. This lens can be used with Olympus Four Thirds mount cameras. For Micro Four Thirds cameras, a mount adapter is required. I think the condition is quite good. I don't see any noticeable scratches or dirt, and the lens doesn't seem to have any mold. However, I am a novice, so I haven't done a thorough check. If you have any concerns, please feel free to comment. I have confirmed that it works with an Olympus E420, for example. I will try to upload images when I have time. Would anyone be interested? The OLYMPUS Zuiko Digital 40-150mm lens is compatible with the Micro Four Thirds mount and offers excellent focal length and brightness. - Brand: OLYMPUS - Model Name: Zuiko Digital 40-150mm - Focal Length: 40-150mm - Maximum Aperture: f/4.0-5.6 - Mount Type: Micro Four Thirds - Lens Cap: Included - Hood: Included Thank you for viewing.
