What are the differences between a Winder 1 and 2?
The only substantial difference is that the Winder 2 permits sequence operation at ~2.5 frames per second. The Winder 1 only operates in single exposure mode. A more subtle difference is that there is a difference in the operating voltage at the electrical contacts between the Winder 1 and the Winder 2, which prevents some *but not all* Winder 1 units from working with later models, esp. the OM-{2S, 4(T)}.
