Thank you for viewing. This lens has been disassembled, and the aperture spring is missing, so the aperture blades do not move correctly. Also, the focus lens does not move to infinity, so it is completely junk. I think it might be possible to take pictures when it's wide open, but I haven't tried it. If anyone is interested, please consider it. The E-Zuiko Auto-W 25mm f/1.4 is a lens perfect for wide-angle photography. - Brand: Olympus - Model Name: E-Zuiko Auto-W 25mm f/1.4 - Focal Length: 25mm - Maximum Aperture: f/1.4 - Lens Type: Wide-angle lens Thank you for viewing.
