One foreword about formats:

4x5 inches and 9x12 cm are different film sizes and need different film holders. Film holders from Linhof and also Graflex, Fidelity and many other makers, in both sizes, fit in a common ground glass back.

That means: the camera is the same, one only has to match the film and film holder and use the same camera back, ground glass. In this text I will use the cm as unit, so I will mention only 9x12.

This camera may look too complicated and indeed it is. Anyway, if I would have to choose only one camera to have for whatever circunstance, it would be either a point and shoot or a Linhof Tecknika. All the others fall short in their ambition.
This is a camera intended to the most carefull image control, with many movements of lens board and back, but as well as hendheld photography. That could easily make it a bad compromise but is is so well designed and finished that one can actually have both with reliability and outstanding quality.
