Buyer's beware. The Nikon has made this lens look better than it is. If you check the serial no. I think you'll find it 1971-ish. It's hard to find the 121's in a Copal shutter. Most are in the funky - ish Compur's. This has some quirks to mention. A few cleaning sleaks. Some Schneider-itis. The cocking lever return spring doesn't work, and it's a little on the loved side in appearance. But if you are wise and all that silly stuff doesn't throttle your enthusiasm, what we have here is a 120mm lens that will just cover 8X10! I never used it on 4X5 or 5X7, I used it on 8X10. If the sale is sluggish I'll go dig up the images. They're gorgeous. I don't think the later 120mm SA's would do that. On 6.5X8.5 it would be ultra wide AND have some minimal movements. Cake and eat it too. I'll need $425 for it. + shipping.
