Obsolete since the 80's, when Polaroid decided to sue Kodak for patent infringement and won (still the largest patent infringement case in history). Kodak was ordered to stop producing all their instant film and instant film cameras.
This EK6 is not missing the name plate that was sent back to Kodak by so many owners for the settlement refund with Kodak that told you to send in the name plate for the refund. The settlement involved four groups of instant cameras made by Kodak with ten cameras in group 1 ($50), fourteen in group 2 ($55), six in group 3 ($60), and nine in group 4 ($70) for a total of 39 cameras. The EK6 was in the group 3 and the money was a combination of cash and redeemable Kodak coupons. After checking the internet and seeing so many Kodak instant-film cameras with their name plate still intact tells me out of the estimated four million possible refunds that Kodak would have had to pay not many sent in the letter. The EK6 used Kodak’s PR-10 instant film, (no longer available), and this film is said to have turned out a finished picture that looked better than the Polaroid SX-70 equivalent. The camera has an f/1:12.8 100mm fixed focus lens. The shutter was capable of speeds up to 1/300 of a second. Other features are the built in flash, optical viewfinder, carry strap, and a ¼ inch 20 thread tripod socket. The camera needs two 6 volt SIZE J batteries that were held in the film compartment above the film slot and a test button with a red LED was located in the back top of the camera. The camera pictured is in good condition and worth $8.00 in 2020.
