Fujinon SF lens Question

[Kevin Crisp]

I picked up the 180mm version, with a red disc. I cannot find any cogent explanation on line for how to read the red numbers and the yellow numbers on the aperture scale. They don't appear to be f stops. (8/9/10 [yellow] and 10/11/12 [ red]) Any help would be appreciated. If somebody has posted the factory instruction sheet on line I sure can't find it.

Thanks.

Kevin. I have the instructions for the 250SF. Those are f stops. I’ll email instructions to you tonight. If I forget, please remind me.

Got it, thanks.

Regarding those Fuji SF lenses, were they sold with both discs or did you have to order the discs separately? I never see one for sale with both discs.

[BrianShaw]

I’m fairly sure they were originally sold with both. But since one could be on the lens while the other is stored — somewhere — that is likely why one is generally missing.
