Format strengths: why do different sized media render differently?

MF tonality and separation: in the full size image, the airplane is in a clearly different focal plane to the tree and hangar – even though it was shot at f8.

I’ve written previously about what exactly contributes to the ‘medium format look’. However, I think to some degree we also need to both define what constitutes the hallmarks of smaller formats, but more importantly figure out where each format’s strengths lie. Having now shot what I’d consider ‘enough’ with a complete MF system wth lenses ranging from ultra wide (24mm, or 18mm-e) to moderate tele (250mm, or 180mm-e) I think I’ve built up a much more complete picture. No doubt this will change if the recording medium size increase further – with the 54x40mm sensors, for instance – but I think it’s fairly safe to extrapolate based on the differences between subsequent smaller formats.
