The Wista 45SP is a 4x5 folding field camera sold by HP Marketing Corp. With revolving Grafloc spring back, folding focusing hood, and bright fresnel focusing screen, this camera was designed for the photographer who wants more than just a field camera.
Wista offers three types of all-metal folding technical cameras. The RF with Micro Swing and rangefinder, the SP (this one) without rangefinder but with the Micro Swing back and the VX with neither rangefinder or Micro Swing. All have interchangeable bellows, a 12" bed that accepts longer and shorter beds, a Graflock back. All are supplied with a folding focusing hood.
The 45-SP has the same features as the 45-VX, plus micro focus back swing for close-up photography. Designed to simplify handling and use of the camera, the variable swing and tilt movements, both front and back, can be easily set. The compact size and light weight of these cameras make them as easy to use in the field, as in the studio.
