Olympus Zuiko Auto-T 300mm f/4.5 - Olympus OM Mount

The Zuiko Auto-T 300mm f/4.5 is a telephoto prime lens for the Olympus OM system. It features a built-in retractable lens hood and a tripod collar for improved balance. Despite its long focal length, the lens remains relatively compact and manageable for handheld use compared to other 300mm lenses of the era. It is well-regarded for its colour rendition and is suitable for wildlife and sports photography where a modest maximum aperture is acceptable. When purchasing a used copy, check the internal elements for haze or fungal growth, which can occasionally affect these older telephoto designs. The tripod collar should rotate smoothly and lock securely. SDS technicians verify the aperture blades are free from oil and snap shut quickly, and that the focusing ring operates without excessive resistance or dry spots.
