Pussy or no pussy, the tonal quality of these is superb Humayun. Great control. The 5D Mark II not having its own (inbuilt) flash, and given the 430EX-ish style Speedlite and standard diffuser's propensity to overpower close-quarter subjects - I really like this acquisition of yours. What model did you buy and in comparison to the standard flash what's its output? Is it a remote, ring, side or top-mount? Nice pussy by the way
