A few interesting things have passed my way recently. The first is the Minolta Paradjuster. This cunning device allows composition and focusing and then raises the camera into the taking position, thus avoiding parallax error at close distances:
The Minolta Autopole is a polarising filter for TLRs. Two filters, connected by gearing, so that the effect you see in the viewing and taking lenses is the same:
Olympus have made a few lenses in their time, but here's a rare 35mm Shift lens, which allows the axis of the lens to be shifted in two directions. Goodbye to converging lines!
Bur kudos to the Vivitar QDOs 3D lens kit, a magnificent beast of a lens with coloured filters that can be switched in to make 3D images. Supplied complete with special glasses and also able to be used as a normal 70-210mm lens.
Just a few items from the things that pass myway!
