Verian: I've just bought one - thanks for the tip. There is a third use for the thingy, now I've thought about it. If I flip my Blad on it's side (slightly counter-intuitive with a square format camera), I'll have WideBlad for landscapes. Or at least, that's how I hope they will read. I think the format will 'trick' most viewer's eyes into believing they are seeing a wide angle view, when it will actually just be an auto-cropped 80mm view.
