The Polaroid 330 camera uses the 8.5 x 10.8 cm (3-1/4 x 4-1/4 in.) Polaroid pack films or Fujifilm FP-100c (color) or FP-100b and FP-3000b (black & white) instant pack films. The camera was introduced in 1969 and manufacturing was discontinued in 1971. The camera has a plastic body, shutter, and lens housing with a 114mm f/8.8 3 element glass lens. The camera also has a separate rangefinder focus plus parallax-corrected viewfinder, a 1/1200sec to 10sec (automatic) electronic shutter, an f8.8 or f42 aperture, a mechanical development timer on the back of the camera, and a Lighten/Darken control Exposure compensation dial of -1/+2 stops. The 330 has film speed settings of 75 and 3000 ASA and has a socket for a preparatory auxiliary mounted flash unit. To operate the flash it uses a no. 532 3v battery kept in a compartment accessed from the back of the camera. The flash unit for this camera used the M-3 flashbulbs. The camera also was able to accept close-up lenses that slid over the outside of the taking lens. Other features were the removable protective cover, easily removable rollers for cleaning, and a handy carry strap.
