A couple of years ago, I bought a Calumet 4x5 with a couple of lenses, one of which was a tiny Commercial Astragon 180mm f6.3. It was mounted in an equally tiny Seiko shutter. I let it remain in the camera closet for a couple of years, and finally took it a few months ago. It is decently sharp, very compact, and I checked up on it, and it seems to be made by Yamasaki, whoever they are. Here is a shot I took with it on my Linhof Color, with HP5 at 1:50 and 12 minutes. This is an 800 dpi quickie for illustration . . . the actual negative is very sharp.
So I got interested. I picked up a spare for 70 bucks on Evil Bay. Then I found a 90mm Stablemate, a 90mm f6.3 Yamasaki Wide Angle Congo, and it just arrived. A delightful little thing that should pair up well on my forthcoming tiny Itrepid 4x5. It cost me 100 bucks including shipping.
Any information about these lenses would be appreciated. Not very much on line and they're fascinating, obscure little critters. Cheap, too. Thanks.
