Home made adapter Sony Alpha body to 2x3 Mini Speed Graphic

I fashioned a home made adapter to mount my Sony Alpha DSLR to my mini Speed Graphic. Then I shot through a 170mm Kodak Anastigmat lens. The set up worked like a telephoto lens with the bellows extended. I could focus to infinity. With the bellows collapsed it worked like a macro lens. I shot with the lens wide open at f/3.5, ISO 400, 1/125 shutter speed. I used a Slik 300DX tripod to steady things. These shots of birds feeding were through a closed patio door.

Thanks
