Collector Notes:
This lens is a strong candidate for DIY cleaning or optical restoration, and still performs well for casual use or adapted mirrorless setups. The fungus may slightly reduce contrast, especially at longer focal lengths, but sharpness remains usable when stopped down. A budget-friendly way to explore super-telephoto photography with classic Olympus rendering.
