430 or 600 reach
« on: March 19, 2013, 08:18:40 AM »
Hi
I read the industry standard rating for the flash strength, but how does that actually translate into reach? How much further can you light a subject with a 600 over a 430?

thanks

Exact distances depend on focal length (really, the flash head zoom setting), aperture and ISO, that's why the spec is a 'guide number'.  But the 600 will light a subject at a greater than a 430, 40-50% further as stated.  With long lenses (>300mm), consider a Better Beamer.
