The German company Novoflex (at the
time a West German company) marketed
over many years two lenses for medium format cameras,
and these lenses were most often illustrated in their
literature mounted on a Praktisix camera or a Pentacon
Six. Both of these lenses incorporated the
Novoflex Follow Focus system, a spring-loaded pistol
grip that is squeezed to focus. Here are the
details (from Gillespie):
|The exact maximum aperture of
the 500mm Tele-Noflexar was disputed and in later years
the lens was produced with the maximum aperture designated
as f/6.3. See the images to the right and below.
In both of these pictures, the older lens is on the right and the newer one is on the left. We note that in addition to changing the maximum aperture designation from 1:5,6 (a common German way of writing the maximum aperture) to 1:6,3, the older lens indicates the focal length as f = 50 cm, while the newer lens has f = 500mm, in accordance with changes at that time in typical designations of the focal length of lenses.

Novoflex final assembly. In the foreground we see two Tele-Noflexar 500mm lenses for medium format cameras.
The man in the foreground is doing final adjustments for a lens for an Exakta 35mm camera.
We see three other famous cameras of the period (probably the early 1960s) on his workbench,
a postwar Contax from Zeiss Ikon, Stuttgart, a Zeiss Ikon Contarex and a Leica.

The high prices of Novoflex equipment, both 60+ years ago and now, reflect not only its high quality but also the costs of employing highly-skilled staff to design the equipment and to ensure precision manufacture in western Europe, plus of course the cost of maintaining and heating a factory in a country that has cold winters.

Novoflex also sold lenses for use with their macro bellows on the Praktisix/Pentacon Six, namely the:
