Zig-Align Model ZP4 for View Cameras (if you do not have ZV1 or ZV1.1) #21582
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.
