For Sale 90mm F6.8 Caltar II-N (Grandagon)

90mm 6.8 Caltar II-N, i.e., a Rodenstock Grandagon marketed under the Calumet brand. This one's a user, with a number of signs of wear--marks or scrapes on the metal. Glass is clean, and speeds sound accurate to my ear, but haven't been tested. I've used this lens for at least five or six years, and it's very sharp, with plenty of coverage. Comes with both caps. $350, plus shipping.USD
