Anyone have any info on the 4x5 Sinar Copy Camera? My search for info on it turned up to be a dead end. I believe it was made for Museums for copying paintings and artworks. I don't believe it had any movements but could be wrong on that.
thanks

Don’t know what Sinar’s was like but here is a picture of Linhof’s. Bellows draw might be different but features must be similar.

Minus the tilts & swings. I've only seen catalog pictures of it. Everybody I know used a regular Sinar P or even F. Why go looking for something less versatile which probably cost more due to its rarity? If someone didn't know how to zero detents or marking on a regular Sinar, why would they know how to make it parallel to a painting?
The camera would have been permanently mounted on a copy stand in our town's Museum. Hauling my 4x5 Norma back and forth every time I want to use it there and having to re-aligning it on the Linhof copy stand's baseboard has become tedious for me. Alas, hoped that the camera was cheaper than a F in that it did not have any movements, and definitely it was not a rarity. Looks like I will have to stick to using my Norma.
That one I showed you was very expensive.Originally Posted by Greg
Cameras like these don’t have movements but the front and back are very carefully aligned and their parallelism doesn’t change while focusing. That is not true for normal view cameras and is the reason Bill Ziegler developed the Zigaline system.
So what, Bob? How does that guarantee parallelism with the original to begin with? Maybe today one could use an extremely precise laser measuring device projecting the 4 corners of the original to four fixed points on the camera back. Not then. And there's no guarantee the original painting and frame itself is dead flat, or even the wall. I'd rather use, and have used, a good loupe and onboard movements to correct flatness visually. Film itself doesn't fit dead flat in the holder either. High quality repro would be done with a big copy camera. This kind of camera is really a small niche. Zigaline was a toy.

Probably made to just stay on a copy stand...

Most any Sinar camera (Norma-F-C-P-X) will do fine as a copy camera mounted vertical or horizontal. It would not be difficult to make a copy board mount to fit a Sinar rail and camera system. Sinar did make a clamp mount for their rails which allows using the camera is odd locations with no tripod or similar camera support.
Fact, most any good 4x5 camera can be made in to a good copy camera. Difficulty will be alignment of item being imaged to the film plane of the camera.
Hasselblad once made a nifty device known as a Linear Mirror where the mirror was mounted on the flat item to be copied. On camera in place of the lens was a ring with a doughnut shaped mirror and a while ring and a small hole in the center of this ring assembly. Flatness and alignment of the camera to flat item to be copied was set by looking into the small hole in the center of the ring assembly and setting the camera or item to be copied's position until the series of concentric rings are equally spaced.
Modified a Sinar lens board to accept the Hasselblad copy widget, worked really well.

"Zigaline" was not a toy, it was a hokey-jokey item that baited more than a few into believe that "thing" could work...... at all.
