Early use of name
Prior to its use on films, the Ektar name originally referred to Eastman Kodak's premium-priced lenses for professional use, which were introduced in 1936 and sold until the 1960s. In contrast to the branding from other lens-makers, Kodak emphasized that the name was a quality mark rather than referring to any particular optical formula.
Original Ektar film (1989 to 1997)
Ektar started as a color 35mm and 120 semi-professional film introduced by Eastman Kodak in 1989, which used the common C-41 process. It was designed to offer ultra-fine grain. It was manufactured in 25, 100 (replaced the poor selling 125 in June 1991 ), and 1000 ISO formats. 400 speed film was available until 1997. Poor market segmentation was cited as a factor in Kodak's decision to discontinue Ektar in 1994. The film was replaced by the Royal Gold line. The 120 version of Ektar was discontinued in 1997.
Relaunched Ektar 100 (2008 onwards)
A new film was introduced in September 2008 under the name Kodak EKTAR 100, which claims to be the finest-grain color negative film with high saturation and vivid colors available on the market. The film was initially only offered in 35mm, but later the film offering was expanded to include 120 size film, then 4x5 and 8x10 sheet sizes in 2010.
