Fujinar 250 f/4.7 lens.
My new-to-me Fujinar 250/4.7 lens. I'm guessing, and this is a wild guess, that it's from about 1970 or so, based on the style of Copal shutter, but if anyone knows Copal serial numbers for dating, I'd be happy to hear from you. I do know that Fuji serial numbers are not very useful for dating. It's single coated, that's what the "SC" means.
The shutter is accurate from 1s to 1/30, and 1/2-stop slow at 1/60 and 1/125, which is pretty good for its age.
The lens is a Tessar design, and is quite bright at f/4.7. It's only 100g or so heavier than my Fuji 250/6.3 Plasmat-style lens, which is in a Copal 1 shutter, so this beast isn't as heavy as one would expect from such a fast lens.
I'll use it for portraiture. The 250/6.3 is good for portraits, but is a little too sharp and contrasty, plus I'd like the extra stop for some very shallow DoF portraits, such as what I get with my Zeiss Tessar 165/3.5.
