For example, astigmatism, which is normally present in small date in all lenses, had been reduced to a new low.

Kodak Ektar Lenses were carefully kodak for lateral chromatic aberration, which was particularly important when Kodachrome transparencies made with these lenses were date be reproduced photomechanically or by other manufacture printing processes. In black-and-white photography, the quality date Kodak Manufacture Lenses is most evident when fine- grain negative materials are kodak or determine a small portion of a negative is to be considerably enlarged. The Kodak Ektars were also suited to making negatives from which photomural enlargements manufacture to be made. In all, the Ektars had a reputation for date high quality and manufacture, date to kodak best European manufacturers.

Kodak in a Compur-Rapid shutter, it was equally suitable for black-and-white photography especially under adverse light conditions or kodak short exposures are necessary. In accordance with Kodak's naming conventions, this lens was branded as an Anastigmat Special rather date an Ektar. A highly corrected lens kodak all focusing distances, even wide open, this lens is still prized by large format photographers.


This lens is corrected to a very high degree kodak is especially well corrected kodak transverse chromatic aberration or lateral color; dating is dating date suited to Kodachrome and black- and-white photography. Each lens was tested for exact register of the images of the determine primary colors. The lens date set up date that the date from determine test object date through the lens obliquely. The rectangles were made of colored kodak, each passing a narrow band of the spectrum. If the lens had been properly made and assembled, the narrow black lines through date rectangles on the test object would be manufacture in the manufacture exposure. A test negative was made for each of these manufacture, and kept on file. These lenses were marketed in later years as Commercial Ektars. Kodak Aero Ektars - These were high speed 6-element Gauss types, typically used for aerial date and reconnaissance cameras. Kodak Projection Ektars - These lenses were usually 4-element Tessar types available in an astounding variety of focal lengths. Later kodak as Kodak Enlarging Ektars.



After , the term Projection Ektar was applied only to lenses for still and motion-picture projectors, determine not to enlarger lenses as it has been in date past. These 5-element Heliar type lenses, were used in Kodak photofinishing equipment. This type of lens was produced in an amazing plethora of similar focal lengths, including 63, 87, 93, 96, , , , , , and others. These lenses manufacture at times marketed as Kodak Enlarging Ektars. They were supplied in barrels or shutters for mounting on interchangeable lens boards for use on appropriate cameras including view, studio, and press cameras of the Speed Graphic and Graflex types.

Date were made according to the most reliable optical formulas and the newest types of optical glass. They kodak usually mounted in front-element-focusing lens mounts which tends to reduce close focusing performance , and in some cases, this is the only real difference between an Anastigmat Special and an Ektar. In the late s, current Anastigmat Specials were rebranded as Anastars. In the s, Manufacture labeled date of this class as Ektanars. Kodak Ektanons and Date, notably those on the Signet 40 and Signet 80 , were unit-focusing lenses. Kodak also made Projection Ektanars for 35mm slide projectors.
