Hi John,
No the Technikas (technical folding field camera with collapsable/exendable beds [3]) do not have any depth of field scales and tilt calculators. Also, no, my Technikardan 45S (collapsable bed/rail design [again in 3 sections], rotates on rail for portage)does not have these as well. A new Technikardan S includes packaged with it some scale information for depth of Field. I have copied, and laminated this information and take it into the field. There are guides/calculators available for tilt calculation.
Part of what makes the Technika cameras so remarkable is the craftmanship, strength, relative light weight (a little over 5 lbs) (and a major competitor to the Speed and Crown Graphic Cameras with much greater movement capability). Additionally, these are some of a small group of 4″ x 5″ cameras that are hand holdable. Additionally, unless removed most of these cameras have rangefinder capabilities that can be cammed (by Linhof) for individual lenses which allow them to not only be handheld, but also for rangefinder focus when used in conjunction with properly postitioned lens stops on the camera bed. If interested, consider the models IV (I owned a modified IV which had been modified by Marflex, the official US Linhof Repair and later stolen), V, Master, or Master 2000 (new, without rangefinder). These cameras all use the same more modern and a relatively standard lens board. The model III uses a much more archaic and more limited capability lens board and camera.
Though front and back tilt may be used most by Landscape photographers for the Scheimpflug rule, the same effect can done for swing (again front and back) to maintain focus along a plane from near to far from the left or right corners or sides of the frame to as far as infinity. Additionally, for the purpose of set-up and the fact that moving the camera only a few inches left, right, up, or down can drastically change the composition, rise, fall, and shift with these large cameras can also be quite useful (you don’t have to physically move the camera). Rise and to a lesser extent fall can also allow the camera lens and/or film plane to be moved to correct for vertical subjects and to keep them on the film if the subject is too tall when directly facing the subject with all camera adjustments set at 0. If too tall this can be accomplished through the usage of front and back tilts used in conjunction with angling the camera up or down at your subject.
Yes the Sinar asymetrical movements are very nice and they had patents on these movements until recently. The Linhof Technikardans and Technikardan S’s were intruduced prior to the patent expiration of the Sinars. Like most large format, Field and Technical cameras they have Center Axis movements. The Technikardans and the Technikardan S’s got around the patents by correcting for their limitations when they were used on their side and the whole camera on the rail was placed at an angle generally with rear of camera high and camera lens down (but could be reversed) and then tilting (what would normally be swing in normal position) the lens and film standards (very ingenious at the time) elliminating the problems of Center Axis movements.
As to your comments about wanting a 617 format, some of the Technikardans (very limited number to be sure) were modified by some inventive people to take a 6 x 24 format (now thats wide). By the way, the 617 camera format is based upon 5″ x 7″ size. This would definitely be possible with this camera size, but the weight would generally be substantially more than 4″ x 5″ (but about 35 sq inches of film versus 20 sq inches).
Since the patents have come off the Sinar cameras 8 or 10 years ago or so, we are now seeing more and more cameras be they studio, technical, or field that have basically the same movement styles like the Sinars. I have not kept on this but, you can check into what camera uses what method. Regardless of the problems with the Center Axis movements, Center Axis movements have some advantages, and the problems that they cause are not in most instances (particularly in the field) that much of an issue. Additionally, most of the time you would not use that many movements at once. And many cameras including the Technikardans have movement capabilities far beyond the lens image circle coverage and projection onto the film plane (image cutoff, meaning no image at the corners- its black for transparencies).
