This near-mint condition vintage SMC Pentax-A 300mm f/4 manual focus lens comes with both caps and UV filter. It is for use with K-mount cameras and adapters. The only things holding it back from being mint are a couple of light scuffs on its exterior and a few dust particles inisde of it. Its focus and aperture adjustments are both smooth and its glass is exceptional with no fungus, haze, or separation to its elements.
