OK, well... here is a Photographer's little slice of hell.

I'll cut right to it. Canon Camera Control software and PhaseOne C1Pro, two of, by far, the most popular chunks of Professional Photography, are not supported in Leopard yet for all Canon cameras, notably the 5D.

Great.

So, if you're getting ready to spring for a shooting station and you have a Canon Pro camera, check the websites before you book that big job!

Canon is here.
PhaseOne here.

fun!
