Specialist Note "Rodenstock lenses are the gold standard in darkroom work. The Trinar 75mm is particularly valuable for those shooting 120 medium format film, as it provides the perfect focal length for standard enlarger heights. Interestingly, many digital photographers are now 'reversing' these lenses on bellows for extreme macro work; because they are designed to be sharp on a flat plane, they perform exceptionally well for scanning or close-up photography. It is a sharp, honest, and beautifully built piece of German glass."

Condition Report Good condition. The lens barrel shows light cosmetic wear consistent with professional darkroom use. The optics are clear, free from fungus, haze, or scratches. The aperture blades are clean and move precisely, and the threads are in excellent condition.
