This is a custom built Polaroid camera using a 250 body and a Kodak Ektar 105/3.7 lens. The Land 250 use pack film (which unfortunately is discontinued), and has the bright Zeiss made rangefinder/viewfinder. The Kodak Ektar 105/3.7 lens is supposed to be a Heliar design, and renders nicely for portraits. Option8 is an experienced Polaroid manual conversion person, and I commissioned him for the conversion. You can find photos from his flickr stream. He added a focusing distance scale, since the rangefinder is only calibrated at the closest distance. The original lens and the Ektar are of different focal length. The shutter works on all speed, and sounds more or less right.
It is a bit difficult to price the custom built camera, but let's say $150 considering the lens is rather good. Shipping and paypal fees included to US 48 states.
