Headers & Codes in the Exakta Lens List 2021.01.25


The Exakta Lens List contains only lenses for the Vest Pocket Exakta (Standard-Exakta) and with Exakta bayonet (original, RTL1000, Exakta66 pre- and post war and Real).

This means that you won't find lenses with the name Exakta(r) but with other mounts (M42, Pentax-K etc.), lenses for cameras with the name Exakta but without an Exakta bayonet or lenses for the Exakta66 based on the Pentacon Six.



Short name of the lens factory (Zeiss, not Carl Zeiss Jena, CZJ or aus Jena), brand name or importer name (mostly for Japanese lenses, sold in the USA, like Vivitar).



Type name of the lens. In some cases the factory or importer used the same type name for all lenses.

NB1 In some cases is is unclear (at least to me) whether the name on the lens is a type name or a factory/brand name. For example, "Vivitar" is considered to be a brand name, but I don't think Vivitar is/was a factory.

NB2 For Zeiss lenses, the full lens names are used, not the indications T, B, S and Bm.



Focal length in millimetres. When a lens has a focal length in inches, the nearest value is chosen (for sorting purposes) and the correct focal length is given under Comments.

A zoom lens gets a focal length 0 (zero) and its range is given under Comments.



Largest possible aperture as written on the lens f:1-xxx. Lenses with two or more aperture values (dual and multiple focus lenses, some zoom lenses) get a 0 (zero) value. The correct values are given under Comments.
