Thank you for viewing. This is a vintage Soviet-made wide-angle lens, the Jupiter-12 (35mm F2.8). ・Markings: JUPITER-12 1:2.8 F=3.5cm ・Mount: Unknown, please check the photos (possibly Kiev/Contax mount). ・Condition: Scratches and minor blemishes on the exterior. 　Optics show some dust and slight haze (possibility of oversight). ・Aperture/focusing ring operation is unconfirmed. Due to unknown maintenance history, this is considered a "as-is" / junk item. ・Accessories: Only the front cap shown in the photos (no rear cap). ※This lens has characteristics typical of older lenses, such as flare and susceptibility to backlighting, and individual variations. Please consider this for collection/parts purposes. ※Returns due to mount incompatibility or compatibility issues are not accepted. Instant purchase OK. I will clean it lightly, package it carefully with waterproof protection and cushioning, and ship it.
