Pentax Super-Takumar 55mm f/2 - M42 Mount

The Super-Takumar 55mm f/2 is a classic M42 screw-mount standard prime lens, renowned for its mechanical build quality and smooth tactile operation. While often considered the 'budget' alternative to the f/1.8 version, it shares the same optical formula with a slightly smaller maximum aperture. It is highly regarded by vintage lens enthusiasts for its pleasing bokeh and sharp central resolution when stopped down slightly. Used examples should be checked for the 'yellowing' common in early Takumar glass, though this model is less prone to it than the radioactive 50mm f/1.4. SDS checks for oil on the aperture blades and ensures the M/A (Manual/Auto) switch functions correctly. The focus helicoid should be inspected for consistent resistance, as original lubricants can dry out or become gritty over several decades.
