My photography habit is largely financed by photography work (but I have a fulltime bureaucratic job to pay for everything else in life). 90% of photography work is digital, but the 10% where I get to use analogue MF or LF film is certainly not for want of quality. Some people (other than us) are really into these things (tone, colour, je ne c'est quoi, hand-crafted, etc, etc.) The last commercial job I did on MF (6x4.5) Velvia was very nice quality indeed - I don't know that it's always a speed thing with digital either - from my experience a big factor is the stakeholders like to see, and thus have a say in the process, and screen on the back makes that easier. After editing and so on, the turnaround is often the same.

Marc!
