And yes, it was refreshing for me too. I like the portrait finder. Once I turned my mind around to it I was even very pleased with it even more. It is a bright finder with good info presented on the side. It is good to be pulled outside your comfort zone once in a while as a photographer and this view finder made me think again about how I compose a shot.
The only time this happened before was when I used a Bronica SQ-B (6x6) for the first time and saw the image on that very large ground glass. I was hooked to the MF cameras immediately and bought me the Bronica. Never regretted it. Later I bought the RF645 too because it was a rangefinder. It often accompanies me on vacations, etc., when I don't have much time for photography, but want more than iPhone snapshots
I love both cameras and both have their merits. I love the quality of Bronica glass too.
