SIGMA MIRROR TELEPHOTO MULTI COATED 600mm f/8 MF Lens for Pentax K 20160627_ETSY_inventory These binocular theater glasses areI bought this lens ~40 years ago at Alfredo's Cameras in New Orleans, La. It's been stored in my dry, air conditioned lab ever since and is in excellent condition. It is contained in its original case and includes the cap, lenshade and 5 filters. This is a multi coated, 600mm f 8 MF mirror Lens for Pentax K mounts. Ideal for capturing detailed images with a shallow depth of field. It's all aluminum mount and manual focus.
