The Zenit S is the first Zenit SLR camera. It uses the body of the Zorki and the M39 lens thread, but the lens is mounted further in front of the film, so the M39 Fed/Zorki lenses cannot fit. These lenses are only suitable for Macro work
The camera has no metering aid, an external lightmeter is needed to select the aperture/shutter speed settings.
The camera has a very difficult way to load the film throufh a slit in the bottom, needs care or else the film will be munced up and there is no way to get into the camera's inside.
After I made it with the film I took some samples using the standard 50mm lens but also some Fed/Zorki lenses for macro.
Here are the results
with the standard Industar 50mm/f3.5
Shop display
Barking dog
Chicken for sale
Roadworks
With the Jupiter-8 50mm/f2 for Fed and Zorki
Only macro is available
With the Industar - 22 5cm/f3.5 retractable lens there is a small flexibility to focus a little further
