The Image 2 is one of the newer cameras from Polaroid. The earlier models shot square pictures (78×78) the Image System / Spectra series came with the new format 97×73 mm. The camera has an automatic light meter as well as an ultrasound distance meter for autofocus. And it comes with a built in automatic flash.
This is by far the easiest to use instant camera ever built. Open it, insert the film magazine, which also includes a battery, open the camera, wait till the flash is ready and shoot. If needed, you can adjust the exposure by setting a switch to brighter or darker.
Lens: 125 mm (equivalent to 46mm on a 35mm film camera)
