Focus cam will fit on 4×5 Linhof Technika III. The leading edge will need to be filed down to calibrate a specific 90mm lens. Follow this tutorial to calibrate the cam. This version is intended to be used with the focus bed at 90 degrees. This will work fine for landscape images, but will cause the bed to protrude into the bottom of the image with portrait orientation. A small amount of shift will overcome this. The advantage of using the level bed is that it is quicker to set up the camera and be ready to shoot. If you prefer to use the camera as Linhof intended, select my version of this cam for dropped bed. This cam is available marked for 90mm and 3 1/2” to match the markings on your lens.
Available in Aluminum or Bronze. Either will work fine. Bronze is stronger, but costs more.
