I have both the Sigma 19mm and 30mm available. I wanted to give them a whirl, and while they are neat lenses, I am just going to stick with my 17+45 combo. They have only had a few test shots taken with each and are indistinguishable from new. $195 each, shipping and PayPal included in the USA. $385 for both. Possible trades/partial trades considered for some film camera and dark room equipment supplies. Things I am specifically interested in are Nikon FM2/FE2/FA, Graflex 4x5, some medium formats (no 645 format), compact rangefinders like Olympus, films, or darkroom stuff including equipment and supplies. i have only an enlarger and nothing else right now. im willing to hear other trade offers but cash is king.
