<p>Yes, IMO Leica could have. The company isn't interested in ground breaking innovation but instead seems to try to stay ahead or afloat by keeping to the small, handheld and expensive cameras but also by adapting the newer innovations - such as digital.<br /> I use a miniature Crown Graphic with a variety of lenses and backs from 645 to 6x9 (Horseman). Still, due slower lenses, it tends to live its life on a tripod more than being handheld. A Leica type camera would have the same problem.<br>
Consider the Mamiya Universal - interchangeable lenses including a 100/2.8. It can do it all (except for meter) but is heavy!</p>
