Take a Spotmatic, replace the screw mount with a bayonet, and you get a legend. Launched in 1976, it was produced until 1997!It is a simple camera, without selftimer or depth of field tester (these were on the KM).It's been a long time I wanted to have one, the selling prices used suggest that it is always very popular. This one had a reasonable price, because without lens, but those sold with the lens all have the "M" 2.0 / 50mm, and I already had this lens (on the MV).Good deal, this camera is in excellent condition, I just changed the rewind button and put a new battery.Warning! the lightmeter is in use as soon as light hits the sensor (like for the Spotmatic F); always leave a cap on the lens (or remove the battery!).
