Here we have the very rare K series '20mm' lens for sale in excellent condition. This was one of the three ultra wide lenses in the K series, the others being the 15mm and 18mm. This lens mimics the qualities of the famed K 28/2 'Hollywood' lens with its deep colour rendition and cinema like vignetting at wider apertures. It's sharp but full of character. This copy is in excellent condition with clean and clear optics and very few markings for its age. There is no fungus or haze, and much less dust than lenses of comparable ages. The focusing and aperture rings have a satisfying feel to them, and the aperture is snappy. The lens comes with original front and rear caps as well as the original leather case that is quite worn. Let me know if you have any questions.
