i used mt nikon d40. the lens is a pentax 50mm f/1.4 at f/16 which is the max for the lens. the lens was mounted reversed (ie front lens closest to the chip) and held on with rubber bands. I could buy an adapter to allow me to couple the lens to body in reverse properly... but i couldnt be bothered
i am really quite happy with this shot. its not cropped at all
my best macro to date me thinks. I will have to make a print of it
