I am selling a mint black 50 lux asph, all original box, case, cap, 6 bit coded. I purchased this lens 4 months ago from a DPI member. He purchased it new about 18 months prior to selling it to me. It was back focusing, so he sent it to DAG for calibration and focus is perfect. I used this lens a few times and am selling it to pay for a different lens. Price $2400 includes shipping CONUS and paypal. It's in perfect condition. Please respond to my e-mail. [email protected]
