Model ZV-1.1 is designed for 4x5 cameras where the range, camera to copy is 0-20 ft. Zig-align products can help you obtain the best possible results in your photographic enlargement and reproduction work. These results come from object, image, and lens planes being precisely parallel. It's a level of parallelism that your original equipment simply cannot deliver after it is shipped, set up, and used.
In addition to the expected gain in uniformity of sharpness, precise parallelism also delivers the best possible lens performance. This surprise benefit is a primary reason for the profound image improvement results you can obtain with our alignment products.
