What strikes me is that nobody has mentioned or questioned why the tog might have chosen to use a 450 for reasons other than the technical output. Maybe the tog prefers to use a smaller body more akin to the size and shape of a 35mm film SLR? Don't forget, all these pro bodies being listed are big buggers, maybe this tog finds that a smaller body is easier to handle or less intimidating for the subjects?
At the end of the day, the tog's the important one. Providing their work stacks up who cares if it's been shot on a Lomo?
