The first Polaroid I bought was a Sun 660. It cost me a $1. This is a pretty deluxe Polaroid! It features a plastic 116mm-f/11 lens, sonar autofocus, electronic shutter (1/4-1/200 second), exposure slider (darker/lighter), and dual shutter release (flash/no flash).
I had a great time with this camera at the High Line Section 2 opening--shooting portraits of architects Diller, Scoffidio + Renfro/James Corner Field Operations and donors such as Diane von Furstenberg with some Impossible PX 600 Silver Shade UV+ black frame film. Everyone wanted to check out the camera and I ended up giving away a bunch of shots because people were so into them.
