Pentax SPII with Kodak Ultra Gold 400
The Pentax SPII or Spotmatic II is a well built mechanical SLR and because it uses the ubiquitous M42 thread for its lens mount there are a multitude of old lenses that can be used with it. You could try to find a solution for the fact that it originally used 1.35V mercury cell batteries including using newer 1.5V silver batteries but I personally don’t even bother with a battery. With its completely mechanical shutter you can measure with a hand held meter or digital camera and then just set the aperture and shutter speed as needed.
The Spotmatic cameras are minimalist in their design but also very attractive in my opinion.
