Olympus EE-1 Red Dot Sight m42 This is just tubes: aThe Olympus EE 1 is a red dot sight designed to make supertelephoto photography a bit easier: instead of peering through the lens and desperately trying to figure out what you're pointing at with your 1 degree view, you can mount this sight to the top of your camera and very easily get things pointing generally in the right direction. In excellent condition, with original box.
