OSD has the 600 EX RT for £363.99, which seems like a damn good price against UK retailers.
They don't however sell a 580 EX II, and it seems to retail in UK around the same price as OSD sell the 600 EX RT.
So if I am to make any saving, I'd having to look at second hand.
Has anyone got any input, should I get a cheaper second hand 580 EX II if I can find one or 600 EX RT?
I like to 'buy once' where possible, which is why I have ruled out the 430 EX II - even though I'm just starting out with flashes!
As in the title the body is a 5dm2, if that makes a difference to the choice of flash. Lens 35mm 1.4 Distagon and 85L 1.2 II
