Rolleiflex is the name of a long-running and diverse line of high-end cameras originally made by the German company Franke & Heidecke, and later Rollei-Werk. The "Rolleiflex" name is most commonly used to refer to Rollei's premier line of medium format twin lens reflex (TLR) cameras. (A companion line intended for amateur photographers, Rolleicord, existed for several decades.) However, a variety of TLRs and SLRs in medium format, and zone focus, and SLR 35 mm, as well as digital formats have also been produced under the Rolleiflex label. The 120 roll film Rolleiflex series is marketed primarily to professional photographers. Rolleiflex cameras have used film formats 117 (Original Rolleiflex), 120 (Standard, Automat, Letter Models, Rollei-Magic, and T model), and 127 (Baby Rolleiflex).
The Rolleiflex TLR film cameras were notable for their exceptional build quality, compact size, modest weight, superior optics, durable, simple, reliable mechanics and bright viewfinders. They were popular and widely imitated. The high-quality 8 cm focal length lenses, manufactured by Zeiss and Schneider, allowed for a smaller, lighter, more compact camera than their imitators. The highly regarded Zeiss Planar f2.8 and Schneider Xenotar lenses, both 80mm focal length and fast in comparison, are both state of the art optics. Unique to the Rolleiflex Automat and letter model cameras, the mechanical wind mechanism was robust and clever, making film loading semi-automatic and quick. This mechanism started the exposure counter automatically, auto-spaced the 12 or 24 exposures, and tensioned the shutter; all with less than one full turn of the film advance crank. This makes the Rolleiflex Automat/Letter model cameras very sought-after for shooting fast paced action, such as street photography. A wide range of accessories made this camera a system: panorama head, sun shade, parallax-corrected close-ups lenses, color correction, contrast enhancing, and special effect filters, all mounted with a quick release bayonet, as well as a quick-change tripod attachment. Some amateur and fine-art photographers still shoot Rolleiflex TLR film cameras with color transparency, color negative, or black-and-white film. The later f2.8 and f3.5 letter models (Planar or Xenotar lens) are highly sought after in the used market, and command the greatest price. Rolleiflex TLRs are still manufactured in Germany by DHW Fototechnik. Historically there were five focal length cameras available including 5.5 cm Rollei-Wide, 6.0 cm Baby Rollei, 7.5 cm (f:3.5), 8.0 cm (f2.8), and 13.5 cm (f:4 Zeiss Sonnar) Tele-Rolleiflex. Although all Rolleflex cameras can be fine user cameras, there is also an active market for many Rolleiflex models as collectables, and this adds (greatly in some models) to the end price paid, particularly in Japan.
Currently Rolleiflex medium format cameras are being produced by DHW Fototechnik—a company founded by former Franke & Heidecke employees. DHW Fototechnik has announced two new Rolleiflex cameras and a new electronic shutter for Photokina 2012.
This first Rolleiflex was introduced in 1929 after three years of development, and was the first medium format roll-film camera, which was used with unpopular 117 (B1) film. It was a Twin-Lens Reflex camera.
Incorporated the first 8 cm f2.8 taking lens (either an 80 mm Carl Zeiss Tessar or Opton Tessar) into the Rolleiflex line. It also added an X flash synch contact.
This camera used a 135 mm/f4.0 Carl Zeiss Sonnar taking lens. The introduction to a 1990 sale catalogue by Sotheby's auction house in London estimated that approximately 1200 cameras existed at that date.
The new Tele Rolleiflex uses 135mm/f4 Schneider Tele-Xenar taking lens
This camera had a 55 mm/f4.0 Carl Zeiss Distagon taking lens. The introduction to a 1990 sale catalogue by Sotheby's auction house in London estimated that fewer than 700 such cameras existed at that date. Only 3600 models have been originally produced.
The new Wide Rolleiflex uses a 50mm/f4 Schneider Super-Angulon taking lens.
Rollei's first medium-format SLR, introduced in 1966.
A 35 mm SLR introduced in 1970.
There are two current models of miniature Rolleiflex digital cameras. These are not true Rolleiflex cameras but are miniature reproductions of the Rolleiflex TLR design produced under license by the German camera manufacturer Minox. The cameras are manufactured by the Japanese company Sharan.
The original model, now discontinued, was the Rolleiflex MiniDigi, a miniature reproduction of the TLR Rolleiflex. In many details the camera retained the details of the original, including a waist level view finder and a hand crank to prepare the camera for the next shot. As the name implies, the camera was a digital reproduction, with the "viewing" lens being a dummy. The camera had a 2 megapixel CMOS sensor in the square format of the traditional TLR. The lens was a 9 mm f/2.8 with 5 elements, focussing down to 10 cm. The shutter speeds were automatically controlled between 1/15 to 1/400 second, exposure time was automatic. The camera was operated by a single CR2 battery. The storage media was either SD or MMC cards.
This was superseded by the MINOX DCC (Digital Classic Camera) Rolleiflex AF 5.0. The name change brings the current model more firmly in line with the rest of Minox's Classic Camera miniature reproduction range. It is visually identical to the original model, but available in both black and red leather finishes. The CMOS sensor has been upgraded to 3 megapixels, with 5.0 megapixels available by interpolation. The taking lens is a 4.9 mm f/2.8; the camera has digital autofocus. The electronic shutter has also been upgraded to a maximum speed of 1/2500 of a second. The camera operates on a single CR2 battery and uses miniSD memory cards.
