This is a nice Yashica 50mm f1.4 Yashinon DS-M manual focus Pentax M42 screw mount lens with protective filter & caps in excellent condition! The lens shows some minor wear from normal use and the glass optics are clean with no scratches, marks, fungus or dirt. It focuses smoothly and the aperture works properly with no problems. This is a fast & sharp normal lens great for everyday use! (May also work on digital cameras with proper adapter) I have a money back return policy if not satisfied so buy with confidence. Shipping will cost $10 within the US or $22 for other international destinations.
