Both Speed Graphic cameras, the Anniversary as well as the Pacemaker Speed Graphic camera, can be equipped with a JoLo lens board.

The JoLo lens board Mark III has been designed for use with the Pacemaker Speed Graphic. 

The JoLo 44" has been developed for use with the Anniversary Speed Graphic. 

Both lens boards can be used with the 7 inch Kodak Aero lens as well as the 8 inch Pentac lens.

Also available are 7 step down rings, enabling to use more metric threaded classic lenses using one of these two JoLo boards as a base mount for the Speed Graphic lens Standard.


The Pentac was designed by L. B. Booth for Dallmeyer and came to market in 1920. It is a 5 elements in three groups lens in the same design family as Voigtländer's Heliar.
8" Pentacs were made for the RAF during WWII by a number of lens plants.

The lens will cover 4x5 at close portrait distances. A fine lens with a classical rendering.
