I have been selling off my Olympus OM mount equipment to pay for my foray into medium format. I have a great condition 300mm f/4.5 lens that I'm putting up for sale. It's always worked amazingly well on my OM-1. Serial number of the lens is 124886. It has the original case, still in good condition, tripod mount with light scratches on the bottom only, original front and rear caps, and has a Niko 72mm LMC-Haze filter. I'll also throw in my Vivitar 3x-21 tele converter. These lenses have a built-in lens hood which only has light scuffing on it. I'd like to get $230 plus $25 shipping/insurance.
