Sort of true Gary - I do most commercial work with digital and have done for about 5 years now - my old Canon 5D is no longer supported by Canon's own capture software, which makes it irritating to use, so that's a forced upgrade for productivity reasons alone. Canon also doesn't support the software for my EOS1v either, but that was a gimmick thing anyway, and doesn't stop the camera being as useful as it ever was...

One other point is that, I routinely post large albums of personal 5x4" work on Facebook, and this generates me a lot of commercial work in unrelated photographic fields - it's like the 'awesomeness' of the large format inspires 'confidence' in my ability to generate good work in that other format :-)

Marc!
