Braun) Subject: RE: military surplus pan camera To: Panoramic Imaging E-mail List Send reply to: panorama@physics1.physics.monash.edu.au I actually ordered one of these in the hopes of converting it into a pan camera. According to the seller, someone had done this and the conversion instructions were included. However, the camera is huge and weighs a ton! (OK, it's about 1 cubic foot and weighs about 40-50 pounds.) Intriguing, but not what I had in mind. I ended up returning it and got my money back. He does have other interesting lenses, prisms, filters and other optical stuff if you are into making your own cameras or telescopes.

Btw, what does 'CPS' stand for....Cycles Pro Second? Gotta have that switched off!....8-)) I once came accross a similar contraption, but with the conotation of UV-Planar 75mm....the 3" matches, but the UV-detail is odd. -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] Date sent: Sun, 17 Aug 1997 23:39:18 +0000 From: Willem-Jan Markerink Subject: KA-71A 70mm panorama camera To: Panoramic Imaging E-mail List Send reply to: panorama@physics1.physics.monash.edu.au I asked a friend about the KA-71A, got an unexpected answer: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx > From this list of 70mm aerial pan cameras, can you explain the > irregularities between frame width vs horizontal angle of view?

Some have more overlap than others; many of these produce not a continuous 180 degree strip but 2 nominally 90 degree with more or less overlap at the middle. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Does anyone know whether this overlap issue is true? Does the rumoured modification take this into account, or is it just ment to operated the camera in horizontal panning mode (as opposite to the vertical panning on the floor of a plane, from horizon to horizon). -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] Date sent: Wed, 15 Nov 2000 16:23:11 +0200 From: SA Photographers Subject: KB18B Navy Aerial Panoramic Camera To: panorama-l@sci.monash.edu.au Send reply to: panorama-l@sci.monash.edu.au One of these beasts is for sale on Ebay.

Craig Woods > > Amaclickclick > SA Photographers Web > http://www.photographers.co.za/ Hi Craig, You might want to check the overview of 70mm cameras on my homepage, some of these aerial dinosaurs are included: http://www.a1.nl/phomepag/markerink/70mmback.htm The main problem with these cameras is that while they have a nifty (mirror) mechanism to shoot 180 degree shots, they do so in continuous high-speed mode, matched to the speed of the plane (I guess), and with rather complex controls. Instructions how to modify these cameras to single-shot mode do exist (I have one somewhere), but this stuff is not for the faint of heart.... I was once tempted to buy a similar unit for US$250 from www.surplusshack.com (or something like that), but passed on it because of all the hassle involved (not to mention the handling of these heavy beasts for actual shooting....it's heaps more easy to take a Noblex 150 plus tripod and shoot 2-3 sequences and stitch afterwards....all that even apart from the inherent problem of finding/ordering 70mm film (if you were already set up for that then you have an argument in favor; or, like me, were looking at Kodak HIE infrared, which doesn't come in 120/220, only in 70mm....however, by now that one is also being offered by individuals as cut-down 70mm, which is still much less hassle than this aerial beast). Wouldn't mind owning one as a show-piece in my living room though....they also exist in 9.5" perforated btw....forklift recommended....8-)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!]
