Here we have a beautiful Sears Auto 50mm F/2 fast prime lens for K mount cameras. This lens is fully functional and ready to produce another lifetime of amazing images. It includes front and rear caps.

The glass elements are free of fungus, balsam separation, haze, and cleaning marks. The aperture blades are free of oil and actuate as they should. The Focus ring spins with a perfectly weighted fluidity, and the aperture ring clicks into its detents with mechanical precision unparalleled in the world of vintage Japanese cameras.

This lens is a real dream, and features incredible optics, impeccable build quality, amazing heft, and superb "feel".

The 50mm F/2 is optically exceptional for a myriad of reasons. For one, it's fast. With a maximum aperture of f/2, it's able to capture excellent photos in extreme low-light situations. This makes it perfect for street photography, low-light portraits, product photography, action shooting, and general snapshots.

When shooting wide open, the lens creates incredible bokeh and has the ability to isolate subjects, rendering them sharp while keeping the backgrounds blurred. Stopped down it becomes incredibly sharp very quickly. Even at F/2 there's very good sharpness across the entire frame, and go further to F/4 or F/8 and you'll be shooting one of the sharpest lenses ever made.

This lens is made for the Pentax K mount and will naturally fit on any K mount camera. In addition, it is the P designated version, which means it will work with cameras that use Program mode (or other in-body lens controls). It can also be used on numerous digital cameras, Micro 4/3, and mirror-less cameras when paired with suitable adapters. If you're unsure of whether or not this lens will mount to your camera, just ask.

The lens will be shipped immediately and packaged securely to ensure safe delivery.
