Capture stunning photos with this vintage Yashica Yashinon-DX Auto 135mm f2.8 telephoto lens. Designed for M42 mount cameras, this lens boasts a smooth and precise manual focus, allowing you to customize your shots to your liking. Its maximum aperture of f/2.8 enables you to take pictures even in low light conditions, while its 135mm focal length and telephoto capabilities make it perfect for capturing distant subjects. With the Yashica brand, you can be assured of the quality of this lens and its durability for years to come. 
The lens is good/fair condition, the body shows signs of wear, the felt on the hood is worn so it is a bit loose.  There is no fungus or haze, but there are some faint cleaning marks on the front element.   Aperture works fine with my M42 to Sony E adapter (not included), but the A - M switch is loose, so it will not work on an M42 SLR.  It will work fine with a DSLR or mirrorless body provided the correct adapter is used (one that will actuate the pin in the back of the lens).
