I have always been a fan of Medium format and I am very happy that the price of it has come down in recent years, but if you have medium format film glass laying around you might want to try a RhinoCam Vertex from Fotodiox. It works by rotating the sensor around the image circle of the lens 4 times and then you stitch them together after the fact. This will not work well with variable light, movement, and swirly bokeh. If you want one they are available from B&H Photo.
