gregvds,
Did you happen to ask Hugo when the replacement for the 45n-1 would be available and if the new design addresses this problem, or did the discussion come up?
All of the corners if it is the loupe made for the M679/Techno system. Note, these are digital view cameras and are not large format. The largest format these cameras can use is 6x9cm.
If you use any other loupe then it rests on the Fresnel screen or on the gg if a Fresnel is not used. It would cover exactly the same part of the image as it would on any other camera.
I know they are digital photography view cameras (see my post n.19). So the loupe is on a kind of pantograph? And the Fresnel screen is made of a rigid material capable of supporting a different loupe? Just technical curiosity...
Or is the loupe covering the whole 6x9 area?
No, the Linhof loupe slides in the slot that attaches it to the camera.
Wista has a sliding loupe arrangement for their 4x5 cameras that slides up and down and left to right on rails. That would be closer to what you are thinking of.
The Fresnel on the M679/Techno is made of the same material as all other view camera fresnels but has a metal hand grip at one end to make sliding it easier. Yes it covers the entire image area. It slides to allow centering it when doing tilts. Most users of these cameras are not shooting film so they don't need the Fresnel to cover the entire 6x9cm area anyway. And most film shooters on these cameras are not shooting 6x9cm. They use 6x7 or 6x6cm.
The "scale of the problems" is that the cameras have to be more precise in their focusing and movements. It has nothing to do with the Fresnel. The Fresnel slides to keep the optical center of the Fresnel in the optical axis of the lens to prevent dimming or blacking out when tilting since asymetrical xis tilts are a modified base tilt rather then an optical axis tilt.
Ok, so if the Fresnel is not rigid how can it support a loupe (non Linhof - post n. 26) and not to touch the gg?
Why would you apply so much pressure with your loupe that you would affect the Fresnel flatness? You rest the loupe on the gg or Fresnel. You don't apply body weight to it. And you don't press the loupe. You do exactly the same thing you would do when using a loupe on a slide, a negative, a print or a stamp. You look. You don't press. And better loupes have large eye relief so you don't have to be right against the loupe at any time.
