Yongnuo 560 Real World Guide Number Table
Flash guide number for the Yongnuo 560 was measured before. What’s new now is a full guide number table with the manufacturer specs versus the Speedlights.net test results – see here below; go for more information to the YN 560 review test results page.
Guide number tables for other models of camera flash can be found in the respective reviews, for example for Yongnuo 460 Mark II, Nikon SB-600, or Nissin Di622 Mark II. The new Nikon SB-700 will soon be added with full guide number test results, too.
Yongnuo Guide Numbers and Flash Comparison
TTL Flashes
Yongnuo currently offers 3 different TTL flashes, all part of the 460 line which means they share the casing and overall design. Among them, the YN465 is the simplest and cheapest (and my favorite), while the YN468 is the most advanced with an LCD screen on the back, but it’s also the only one that’s available for Canon only.
SB-700 Guide Number Details
The instruction manual of the SB-700 is available for download now from Nikon, and I could finally have a look at the guide number table. Before, all that was known was the GN at 35mm FX, and sadly that GN of 28 (m) is lower than the one of the SB-600 (GN30) it replaces.
But in contrast to the 600 there is sensor size detection available on the SB700 now, which means that it does not zoom to the 50mm reflector position when a 50mm lens is used with a DX camera like the D7000 or D90, but it zooms to around 70-75.
