Info on Fuji 300mm f 5.6 "S"

[rhbphoto]

I have just purchased a Fujinon f5.6 300mm "S" lens. I'm looking to economically upgrade my 8x10 gear as my current lens selection is rather archaic. I have not been able to find any information on this lens.
It comes in a "silver" Copal #3 shutter and from photos appears to be single coated. I have a number of Fuji lenses for my other formats and have always been pleased with their performance. This lens does not
appear in a 1979 catalog I have nor is it mentioned in all the on-line sources normally cited. I'm thinking it is an earlier "L" design, Tessar? (though someone on another board thought it might be a convertible and
someone also mentioned that it might be actually in a Copal 3s shutter), perhaps a not for export lens. This copy is supposed to be quite clean and I got it at a reasonable rate.129084

here's one thread that isn't all that helpful but it's here:http://www.largeformatphotography.info/forum/showthread.php?110828-Fujinon-S-300mm-f-5-6-copal-3

It's obviously in a Copal 3"S" shutter, so is that what you are referring to? If it's single-coated and exceptionally heavy for its overall size, it could well be an L.

Thanks for the info. I'm curious and will probably have my answers when it arrives. Vinny, very nice camera. I can appreciate your craftsmanship.

You lens is looks like it might be the "LS" which, I believe, is an "L" threaded to fit a Copal 3S shutter. The other "L" is threaded to fit the Copal 3 shutter.

Yes I believe this is the lens, the diagram seems to match. Fuji lens labeling is often confusing/confounding. Hopefully it will be an improvement over the barrel lenses and huge Caltar/Ilex I currently have, in the
sense of ease of use. Portrait subjects can only deal with so much fiddling. Thanks for the input. Hope to test next week.
