The camera was designed to accept Satz-Zeiss lenses of either 7, 11.5, or 14 inch length. The picture below left shows the aperture scale with provisions for all three focal lengths. The triple-duty features did not stop there, though - there were also three separate focusing scales for the different focal lengths.

The Adams designed shutter is a wonderful combination of brass and steel, and fires with a firm and resounding 'thunk'. As seen in the image below left, the shutter is set by pulling out the small brass knob marked 'Set' until it catches. Then, pressing the brass 'Releases' button fires the shutter.

Along with the camera itself came the patented Adams Changing Box, very well made in brass and what looks to be polished walnut or mahogany. The leather sleeve on the top of the changing bag is still supple, intact, and light-tight.

The bottom image shows just how far the camera and its double-extension bellows could be opened for telephoto or close-up work. The lens supplied with this example is a 14" Zeiss Anastigmat - a telephoto for the 4 x 5 plates the De Luxe took. McKeown's describes the De Luxe as a quarter-plate camera; the fact that this is designed for 4 x 5 simply highlights the fact that Adams & Co. made many cameras to order, and therefore unusual examples may be more the norm than the exception. This camera bears serial number 153 - it is reasonable to assume that not many De Luxes were made, as very few make it to the collector's market today.
