However, I see it as combining the main downsides of film and digital. The reason most people shoot film these days is the look that film gives the image which digital just can't seem to reproduce. People shoot modern digital cameras primarily because of the huge amount of features and improvements over film cameras. This gives you neither.
The main reason I can see for someone to want one of these is that you really want to shoot using a film body but you don't want to pay for or deal with the hassle of film. I wonder how many people that's actually going to end up being when this ships.
