As I get older, I find I am more interested in things from the past. 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

1890 meets 2010; a contrail with a faint view of the passing jet:

I will find some period subjects when I get the project completed.
