Carl Zeiss Oberkochen Large Format Lenses 1950-1972
Large format lenses from Carl Zeiss Oberkochen 1950-1972 © 2013-2019 Arne Cröll – All Rights Reserved (this version is from October 4, 2019) Carl Zeiss Jena and Carl Zeiss Oberkochen Before and during WWII, the Carl Zeiss company in Jena was one of the largest optics manufacturers in Germany. They produced a variety of lenses suitable for large format (LF) photography, including the well- known Tessars and Protars in several series, but also process lenses and aerial lenses. The Zeiss-Ikon sister company in Dresden manufactured a range of large format cameras, such as the Zeiss “Ideal”, “Maximar”, Tropen-Adoro”, and “Juwel” (Jewel); the latter camera, in the 3¼” x 4¼” size, was used by Ansel Adams for some time. At the end of World War II, the German state of Thuringia, where Jena is located, was under the control of British and American troops. However, the Yalta Conference agreement placed it under Soviet control shortly thereafter. Just before the US command handed the administration of Thuringia over to the Soviet Army, American troops moved a considerable part of the leading management and research staff of Carl Zeiss Jena and the sister company Schott glass to Heidenheim near Stuttgart, 126 people in all [1]. They immediately started to look for a suitable place for a new factory and found it in the small town of Oberkochen, just 20km from Heidenheim. This led to the foundation of the company “Opton Optische Werke” in Oberkochen, West Germany, on Oct. 30, 1946, initially as a full subsidiary of the original factory in Jena. -

T-Mount - Wikipedia
4/1/2020 T-mount - Wikipedia T-mount The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a T-mount male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric Type screw thread on the lens with a flange focal distance of 55 mm and a External diameter 42 mm mating female 42mm thread on a camera adapter or other optical component. This thread form is referred to as T-thread. (This Flange 55 mm should not be confused with the M42 lens mount which is also Connectors None 42 mm diameter, but has a 1 mm thread pitch. The T-thread is sometimes described as "M42x0.75," which is the usual manner in which to describe the thread.) The "T" is said to stand for Tamron or Taisei, a Japanese manufacturer that released in 1957 the first of a line of aftermarket camera lenses that fit 35 mm SLR cameras built by various manufacturers using their universal T-mount. On the first model, the mini T-mount used a M37×0.75 thread; Tamron's canonical M42×0.75 T-thread didn't appear on the market until about 1962. The company referred to it variously as a T-mount, T-thread, T-adapter, or a T-400, but not as a T-2, which is simply the name that Soligor used for its version of the T-adapter. The proprietary lens mount of each camera manufacturer was adapted to the T-mount thread with a simple adapter. -
A Theoretical and Practical Introduction to Optics a Theoretical and Practical Introduction to Optics
White Paper A Theoretical and Practical Introduction to Optics A Theoretical and Practical Introduction to Optics Be honest: do you really know how to calculate the focal length of a lens? If so, you are an exception to the rule and can stop reading here !! For the rest of you, here is a second chance. Back to square one "Piece of broken glass starts forest fire"– a common headline during the summer. But how could this have happened? Due to the enormous distance between the Earth and the Sun, the Sun only appears as a tiny point emitting parallel rays of light (figure 1a) Should these parallel rays pass through a lens (or a piece of glass, which has similar characteristics) the rays would meet behind the lens at what is called the focal point. But what happens if our point of light is so near to the lens that we can not assume to have parallel rays of light? They cross each other behind the focal point (figure 1b). If we take a look at the image of our point of light at the focal points position we will see a unclear blurred spot. And so the question arises- "what is focusing?". Focusing is to increase the distance between the focal plane and the lens until the focal plane and the junction of the rays overlap each other (figure 1c). Thus, for single points of light the situation is quite simple. But what happens to the image of screws, PCBs or plates of steel? From points of light to images A point of light does not necessarily originate directly from the sun, candles or lamps, it can also result from a reflection. -

First Impressions - Fuji Velvia 100 Text and photography Copyright Guy Tal All rights reserved. Most film photographers will tell you there are ups and downs to every emulsion on the market. With so many uses and characteristics, there is almost an art to matching the right film to the right situation. Most of us narrow our selection to one or two that, once we are familiar with, provide consistent and predictable results within their limitations. My own two films of choice these past years have been FujiFilm's Velvia 50, and Provia 100F. I will use one or the other depending on the contrast range of a given scene, whether or not long exposure is needed, the quality of light, and other considerations. Yet, in some situations, I struggle with tough choices – Velvia's palette vs. Provia's latitude, Velvia's exaggerated contrast vs. Provia's tendency to produce color casts, etc. The recent introduction of FujiFilm's Velvia 100F was preceded by a lot of exciting rumors – fine grain, rich palette, and extra color correction layers. Once I was able to get a hold of Fuji's technical data sheet for the new film things got even more exciting – claims of improved reciprocity characteristics allowing for exposure times up to a full minute with no need for either color correction or exposure compensation, extremely fine grain to match Provia 100F and excellent resolving power to match the older Velvia. Issues of color, contrast, grain, speed, color casts, reciprocity, and resolving power are just a few of the things a film photographer may consider when deciding on the "right" emulsion for a given scene. -

Lens Mount and Flange Focal Distance
This is a page of data on the lens flange distance and image coverage of various stills and movie lens systems. It aims to provide information on the viability of adapting lenses from one system to another. Video/Movie format-lens coverage: [caveat: While you might suppose lenses made for a particular camera or gate/sensor size might be optimised for that system (ie so the circle of cover fits the gate, maximising the effective aperture and sharpness, and minimising light spill and lack of contrast... however it seems to be seldom the case, as lots of other factors contribute to lens design (to the point when sometimes a lens for one system is simply sold as suitable for another (eg large format lenses with M42 mounts for SLR's! and SLR lenses for half frame). Specialist lenses (most movie and specifically professional movie lenses) however do seem to adhere to good design practice, but what is optimal at any point in time has varied with film stocks and aspect ratios! ] 1932: 8mm picture area is 4.8×3.5mm (approx 4.5x3.3mm useable), aspect ratio close to 1.33 and image circle of ø5.94mm. 1965: super8 picture area is 5.79×4.01mm, aspect ratio close to 1.44 and image circle of ø7.043mm. 2011: Ultra Pan8 picture area is 10.52×3.75mm, aspect ratio 2.8 and image circle of ø11.2mm (minimum). 1923: standard 16mm picture area is 10.26×7.49mm, aspect ratio close to 1.37 and image circle of ø12.7mm. -
