From its first SLR introduced in 1960, Konica advertised that one of the advantages of its system was the ability to adapt lenses from other manufacturers. Konica designed its SLRs to have an incredibly short “film-to-flange” distance (40.5mm). This meant that while Konica lenses could not generally be adapted to other systems, many lenses could be theoretically adapted to Konica. During the original F series run (1960-65), Konica produced OEM adapters for both Exakta and M42 lenses. During the Autoreflex era (1965-1987), Konica produced adapters for lenses in the Exakta, M42, and Nikon F mounts.
The number and type of lenses for the Exakta, M42, and Nikon F systems are staggering. These all-metal adapters work wonderfully for their intended purpose. The only real inconvenience is that because Konica AR bodies are all “shutter-speed” priority, the light metering only works in “metered manual mode.” That means that: (1) the lens must be stopped down to the taking aperture for the camera to take an accurate meter reading; and (2) you must set the shutter speed so that the viewfinder shows a blinking light (or needle reading for older AR cameras) in the blank space above maximum aperture. The manual explains it better than I could. Too bad Konica never produced an aperture-priority camera body, because that would make this so much easier.
Instructions
Here are the instructions if you need to see them.
The Praktica / M42 Adapter
The Nikon F Adapter
The Nikon adapter allows one to use most F lenses on an AR body, with the exception of the newest G, AF-S, and AF-P and any other lenses that lack a manual aperture ring. This means that most non-Ai, Ai, Ai-S, AF, and AF-D lenses will work just fine.
