I'm interested in getting an Automat. http://www.antiquecameras.net/rolleiflex.html I'd probably want the internal baffles but I'm not sure if I should necessarily opt for the type 5. When people recommend the Automat, they usually recommend the last one: type 5/MX-EVS. Is there a real functional/optical difference between the two outside of the EVS system? If that's the only difference then I'll get whichever one seems like a better deal.
