|I purchased all three lenses from B & H in the early '90's. The Olympus OM Zuiko 300 F4.5 and the Tokina 90 F2.5 in an OM lens mount are in perfect working condition and look near new. The Sigma 400mm 5.6 APO has issues with the asking price reflecting those issues.
Olympus OM Zuiko 300mm F4.5:
In like new condition with Olympus OM lens case and box. $170.00
Tokina 90 F2.5 macro lens with 1:1 Tokina matched converter in Olympus OM mount. In like new condition with case and box. $150.00
Sigma 400mm F5.6 APO lens in Olympus OM mount. Internal lens element is starting to develop haze. There are several scratches on the barrel. The lens was used extensively with some barrel looseness evident. The lens does work properly as is and will produce good images. $50.00
All shipping at cost. Thanks for looking.
