Among the gadgets that I have squirreled away is a landscape lens for a dry plate camera, manufactured around 1890. The lens is a Ross London No. 6 Symmetrical 8-inch focal length, to cover 5x7 inches, and it is equipped with rotary Waterhouse stops from f/16 to f/64. I am in the process of fitting the lens to a M42-mount lens board to permit its use on a Pentax bellows unit attached to my Olympus E-1 DSLR. For a dry run, to be sure that I had the dimensions correct, I assembled the parts in a temporary manner to take a few test shots. All shots were hand-held; I'm sure that the use of a tripod would improve things. The lens itself. A similar lens is shown under Ross on the Camerapedia.org website: http://gallery.leica-users.org/v/OldNick/Ross+Lens+2.jpg.html A black and white image to look at sharpness and contrast: http://gallery.leica-users.org/v/OldNick/Michelin+bw.jpg.html 1890 meets 2010; a contrail with a faint view of the passing jet: http://gallery.leica-users.org/v/OldNick/Contrail.jpg.html I will find some period subjects when I get the project completed.
