Rolleimot

The Rolleimot was an accesory intended to provide automatic film advance mechanism and shutter release for the Rolleiflex and Rolleimagic TLR cameras (Rolleimot 1 and 2) and Rollei SL 66 camera (Rolleimot 3). It can be handled with a wire remote control from 3m(10 feet) to 200m (650 feet), the 6v motor needed four D size batteries to work, it was manufactured from 1963 to 1969 (click on thumbnails).


Rolleimot 1 and 3 size is 100x180x180mm, the Rolleimot 2 shown above (diagram) size is 100x220x180mm, it was taller to compensate the camera height with the special 150 frames magazine, only 10 Rolleimot 2 were made.

ROLLEI P-11 PROJECTOR

The Rollei P-11 projector (images below) was manufactured from September 1960 to the ending of 1978 in Braunschweig, Germany, by F&H, it had a few minor changes during the production, about 76200 units were made. It can project 24x36mm, 4x4cm and 6x6cm slides, it is provided with a remote control for the slides change and lens focusing. The P-11 can use several lenses manufactured for the 74 Tube, including those made for newer Rollei MF projectors; the P-11 in the images is provided with a Vario- Heidosmat 3,5/110mm-160mm made by Isco, it allows to vary the projected image size without to move the projector. It uses G17 q 4 feet base lamps, 300 watts for normal projection and 500 watts for large rooms projections (it requires an additional heat filter included in the P-11 case) . Halogen lamps could only be used via a conversion work, during lasts years of P-11 manufacture there was a dedicated 400 watts halogen lamp, but they are no longer available, it's more easy to find a new old stock lamp (images taken with a digital P&S camera, click on thumbnails).

Rollei Large Format Camera

The Rollei LFC camera was designed and built by Dr. Wester-Ebbinghaus (photogrammetric parameters) and engineer Claus Prochnow (mechanical and electronic construction) from Rollei.
This camera was a terrestrial photogrammetric camera dedicated to the Airbus aircrafts industry, they needed exact images about the airplane fuselage parts to preview the way they would match because these parts were manufactured in different countries. The viewfinder was a modified Rollei 3003 camera QBM mount with parallax compensation (you can get an idea about the camera size comparing them). It used interchangeable Schneider Super Symmar 5,6/165mm and 5,6/210 lenses, the format was 230mm x 230mm (9"x 9"), it was provided with a 290 frames film magazin, it had an incorporated ring flash and central shutter with motor (1/125 to 4 sec shutter speeds). A microprocessor controlled the camera functions via several motors, the reseau had 12996 crosses. The camera was built from 1989 to 1995 and 10 units were made only.

Rolleiflex SL 35M Rolleinars


Rolleiflex SL 35 cameras models: SL 35; SL35M; SL35ME; SL 35 E (electronic shutter and smaller than the previous models) were cameras with excellent Carl Zeiss and Schneider optics, however the cheaper Rolleinar lenses line were excellent too, they were provided with modern Japanese design by computer software (Mamiya and Tokina and Kiron and Sigma mainly) and offering zoom lenses no available for the German lenses line initially. You can see in the photograph a Rolleiflex SL 35M camera made in Singapore with a Rolleinar MC f4/80-200mm zoom and a Rolleinar f3,5/200mm prime lens to the left (click on thumbnail, taken with a digital P&S)).

Rollei 35 with Vivitar 283 flash


When the Rollei 35 was designed, most electronic flash units were big too much for the little camera; Rollei preferred to place the hot shoe on the camera bottom to avoid heavy loads on the camera top where some mechanisms could suffer damage. The Vivitar 283 looks big for the Rollei 35, it works with the camera, but the flash-camera combo is uncomfortable to handle due to the Rollei 35 small size and the fact the best position to take the photograph is with the camera bottom up to diminish some horrible shadows risk, a smaller flash is a "must" for this camera (taken with a digital P&S and the camera automatic flash,click on thumbnail).-

Carl Zeiss RB 50/30 aerial camera

Franke & Heidecke as civil firm did not have a significant militar production during the WWII, however they were required for some specific work sometimes like to manufacture the Carl Zeiss RB 50/30 aerial photogrammetric camera used on several Luftwaffe aircrafts for aerial reconnaissance, this camera was provided with motors to work automatically, it took 60% overlapped images that could be used sterescopically too. Anyway this camera needed some parts and accesories to work that F&H did not manufacture.-
