Olympus Zuiko Auto-T 100mm f/2.8 - Olympus OM Mount

The Olympus Zuiko Auto-T 100mm f/2.8 is a compact short-telephoto lens for the OM system, renowned for its excellent performance-to-size ratio. Measuring roughly the same length as a standard 50mm lens, it provides a 5x magnification relative to the 35mm format, making it an ideal choice for portraiture and travel. It features a five-element optical design that delivers sharp images with pleasing background blur. Used units should be checked for the presence of fungus, which can be common in older telephoto primes. SDS ensures the focus helicoid is smooth and not gritty, and we check the aperture blades for oil contamination which can lead to slow response times. The filter thread is inspected for dents, as the front element sits quite close to the edge of the barrel.
