Hi!
The 45° Viewfinder built by UK-GERMANY is now available. I've seen the first samples mounted to a Canon 5D housing:
The finder has an angle of view of about 40° at a distance of approximately 45mm from the rear lens. This allows to view the whole finder area with a mask at a scale of 1:1. It has a ball lock to snap in position at 90° steps when rotated. Correction for +/- 3.5 diopters.
Now the really good news: The finder isn't restricted to UK-GERMANY housings only (it is backward compatible to nearly all existing UK-GERMANY housings). The finder is available to all housing manufactureres and DIY projects as well. It may be easily customized to fit housings on request.
The only bad news: I have no pricing information yet but I expect it to be at a competitive level.
If you're interested, please drop me a mail. Manufacturers welcome!
