I guess it is one of those things that eventually catches up with you. So in 2006 I took the plunge by buying a small digital Sony and in 2007 a Canon 5D, later upgrading to a Canon 5D Mark 2 then Mark 3. I am now conversant with the Canon and I really like the way you can balance the ambient light with the flash. I do this with the aid of my Gary Fong diffuser which I find invaluable. I also have a Sigma ring flash, so with one camera and 2 flash guns, I can virtually replicate any of my previous techniques. The thing people do not realise with digital is that what you should be constantly adjusting is the iso.
