If you couldn’t quite afford that vintage Leica nor its digital M8 version that you were groveling for, you might consider getting a mini replica of it from a Japanese company by the name of Komamura. They have been offering mini replicas of vintage cameras for some time now, but have just recently added the Leica M3.
As you can see from the picture, it is incredibly small, measuring in at 74 x 44 x 47mm and weighing 110g. But this palm-sized gizmo is no toy. It is a completely functional 5 megapixel digital camera with 32MB of internal memory, SD card reader, and LCD display on the back. Priced at around $420.
