UsedPhotoPro Thanks for the tip, is this the only one support both *TTL modes ?
Btw, remember in the old days, most flashes are rated at 35mm instead of 50mm, or even 105mm, for example the Metz 45CT4 is GN 45@35mm/ISO100 etc., I actually tested it with a flash meter and a gray card and I got slightly over 45 in manual mode, where most other made are lower than published figure. Since the output power of the flash is governed by the size of the flash tube and the capacitor, those 'tiny' hotshoe flash claimed to produce say GN 50 is no double in zoomed mode, simply by look at the size of the flash unit we can tell roughly what we can get from it.
