This
is a cheap plastic shift lens (PC = perspective control). You can
buy the lens adapted to several standard mounts, I chose M42 for an
easy adaption to my camera. The lens can be shifted 3.5mm off axis in
any direction for perspective control. It's based on a 3-element F 5.6
plastic lens with only 2 apertures: F 11 and F 22. So this is a very
slow lens. There is no
focusing, it covers 1.5m - ∞ at F11 and 1m - ∞ at F 22. It covers full
format nearly without vignetting. It has some colour cast at the edges.
It can of course not compete with an ordinary shift lens, which is very
expensive. But you can play with perspective control and its limits
before you invest into a real lens. Quite some fun to try out and see
the effects of shifting for very little money.
