Different tastes for viewfinders I guess. I use an MF rangefinder and it gives me perfect focus but it is not the nicest one for composition. APS DSLR cameras compromise on the viewfinder but my FF DSLR is already better for composition but not as nice as the TLR viewfinder Istvan mentioned or an MF SLR with and without a prism. The digital camera without a mirror has no optical limitation on the size of its digital EVF viewfinder or the EVF position, vertical or horizontal. Not talking about a display on the back but a proper viewfinder that resembles the TLR viewfinder more but of course replacing the foldable loupe with digital enlarging in the viewfinder. The TLR had either a 56x56 format or a 40x40 mm (Baby) format and the viewfinder had to have the same size given the TLR concept. The same for the Gowland reflex that has an even larger format. As written tastes for viewfinders differ.
