The T and T2 have a fixed 38 mm wide-angle Sonnar lens (5 elements in 4 groups), while the T3 uses a redesigned 35mm Sonnar lens (6 elements in 5 groups).
The Yashica/Kyocera-built Contax cameras employed a new family of lenses. Ending Aug 16 at 1:30PM PDT 2d 8h.
The series was made in Japan by Not all Contax flash units are compatible with all cameras. The new design chief Wilhelm Winzenberg was not involved in the camera side of Zeiss-Ikon, this also allowed a brand-new Contax design to be developed, to follow Hubert Nerwin's wartime plan to make a Contax SLR camera.
The resultant Contax IIa and IIIa models, while sharing many similarities with the prewar forebears, also showed significant simplification and cost-cutting by using cheaper materials, due to the lack of resources. Contax marketed a line of accessories dedicated for the G series of cameras and lenses.Horizontal field of view, i.e., along the 36 mm side of the frameVertical field of view, i.e., along the 24 mm side of the frameDiagonal field of view, i.e., along the diagonal of the film frameZeiss states the focal length of this lens is 16.5 mm.Zeiss states the focal length of this lens is 21.5 mm.Zeiss states the focal length of this lens is 28.5 mm.Zeiss states the focal length of this lens is 35.1 mm.Zeiss states the focal length of this lens is 46.9 mm.Zeiss states the focal length range is between 36.5 mm and 68.2 mm. However, its operation was something of an acquired taste, which explains the more conventional successors, the Contax II and III models. G-series Contax models used a unique bayonet mount offering auto-focus coupling mechanism. Shutters were still guaranteed for 400,000 cycles. 0 bids. The two G-series cameras have titanium-clad bodies and use the Critics were quick to accuse the G1 of not being a "true" (mechanical) rangefinder, since it used autofocus and electronically linked mechanisms.While there is an electronic connection between camera and lens to transmit data, the lenses have no AF motor and no means to adjust focus on the lens itself; both autofocus and manual focus are driven by a motor in the camera through a mechanical "screwdriver" coupling.Compared with the original G1, the G2 has improved autofocus performance and higher top shutter speeds of A new active auto-focus system has been added to the G2, which uses near-infrared beams to set the range.The flange distance between the front surface of the lens mount and the film plane is only 29 millimetres (1.1 in), and Contax released the GA-1 adaptor which allowed the use of The very high optical quality of the G-series lenses makes them excellent candidates for use with high-resolution digital sensors. The combined viewfinder and rangefinder was not the first one on the market, but it was the first on a system camera which offered significant operational advantage, a lead ahead of the Leica until the Leica M3 of 1954.
Another improvement over the G1 was its full parallax correction viewfinder. Like the Contax, as long as the shooter knows how to make … Lenses for the Dresden-built Contax single-lens reflex cameras used the M42X1mm screw mount, but as existing designs intruded too far into the camera body, making the swivelling mirror unable to clear the back of the lenses, a new series of lenses were made by Carl Zeiss of Jena, and later on, Hugo Meyer of Görlitz was also engaged as the second official supplier of original lenses.
These included the following: The lenses used optical formulae not often used by Zeiss, which had specialized in SLR photographic lenses for many decades prior to the G Series. Traditionally, lens makers like to mark the location of the company conspicuously on their lenses. Apart from refining existing designs, Carl Zeiss of Oberkochen also designed new lenses for the post-war Contax IIa/IIIa too:

To stop there would be an undersell.
(These formulae appear to be repeated in the later Kyocera introduced a series of highly successful T-series compact cameras, offering Zeiss-designed lenses which appealed to photographers desiring high quality optics in a compact form. Adapters are available for the Early versions of the G1 could only accept the four original lenses (16 mm, 28 mm, 45 mm, and 90 mm). This major technical advantage was critical in establishing the 35 mm SLR as the definitive camera type for the decades that followed. The following lenses were made for the N-mount systems which offered auto-focus function. The 15 mm In contrast to the contemporary Leica which was evolved from its original concept into a photographic system, the Contax was designed as the heart of a photographic system from the start. The following lenses were made for the Contax 645 systems which offered auto-focus function (apart from A-M-P 120/4 which was a manual-focus lens). The actual AF system, unlike AF for SLR cameras, used a twin-window rangefinder, but the alignment determination was electronic.
The Zeiss Ikon Model 563/24 was a complete redesign of the previous II/III cameras, and was sold by Zeiss Ikon from 1950 to 1961.
Since the new The original series of lenses for Contax were mainly new designs by Ludwig Bertele, under the The Contax I-III lenses were initially finished in black (for Contax I), but later in chrome (for Contax II and III), and offered in a wide range of focal lengths.
