The Kodak Instamatic 25 Camera is a viewfinder camera for 126 Kodapak film cartridges. The 25 replaces the first Instamatic, the Instamatic 50. The Instamatic 25 was made from 1966 to 1972 by Kodak Ltd. (England) and Kodak Spain. The cameras externals were designed by Kenneth Grange and the Internals, including shutter mechanism, were designed by Alex Gow. The camera has a two-speed shutter with a speed selector that can be shifted from the sun symbol (1/90 of a second) to the half-sun symbol (1/40 of a second). The camera uses a Kodak 1:11/43mm lens with fixed focusing and fixed aperture. The camera also has a reverse Galilean type viewfinder, flash shoe for Kodalux bulb flashes, right thumb film advance wheel, a view window in the back cover for frame count, and the camera weighs only 5.29 ounces (150 grams). The Spanish version of the 25 has the Kodak label on the camera body to the film advance wheel side and the English built version is labeled on the lens/shutter assembly. The camera came with a semi-rigged case that has a locking mechanism that uses the wrist strap eye connector to hold the camera in place. You have to pull on the tab on the side of the case to remove the camera. While the case is being used any wrist strap needs to be removed.
