580EX2 against 600EX more power ?

(1/1)

Timothy_Bruce:
wonder if the 580 has more power ...
580EX2  58 at 105mm  and the 600EX  is 60 at 200mm.
what will the 600 have at 105mm ?
anyone know about ?

MikeHunt:
Even though the manufacturers typically quote the maximum flash distance fully zoomed, the standard comparative test is to measure all flashguns at 35mm angle @ ISO = 100 and the old 580EX2 is rated at GN 36 at 35mm, but test results have shown it higher (see link below)

What we really need to see from the new 600EX and 600EX-RT is the GN @ 35mm
