📐 Compatibility note – vintage tolerances
Manufacturing tolerances in vintage optics mean that barrel diameters can vary slightly between production years or factories. This gear is made to fit the most common specifications for this model.

To ensure a perfect fit, please confirm your lens diameter matches the gear’s inner diameter. If your lens measures differently, or if you prefer a guaranteed match, consider my custom gear service — simply send your measurements for a bespoke fit.
