Kodak Retina IF (type 046)
The Retina I F is a 35 mm viewfinder with a match-needle coupled selenium light meter made by Kodak AG from 1963 to 1964. It features a Schneider Xenar 2.8/45 lense on a Prontor 50 LK shutter and a AG-1 bulb slot on the top with a foldable reflector.
About 37,000 pieces were made.
As an improved version of the Retina I F, the Retina II F offered a rangefinder.
The Retina IF and IIF featured an integrated flash in its simplest form: a small flip-up reflector and a flash bulb socket. Due to the space taken up by the flash unit on the top housing, the frame counter moved to the base of the camera for the first time in the long history of Retinas. Also on the base of the camera was a battery compartment, necessary for firing the flash only. The Retina IF had no rangefinder and the shutter (a Prontor 500 LK) and focus scale were the same as on the last Retinette IB model. Exposure setting was similar as on the Retina IBS. Curiously, no flash specific settings are indicated on the camera.
