By cons it is strictly speaking outrageous that Canon does not provide more specific information on the conditions of use of Flash. In summary prefer low diaphragm and high ISO sensitivity ... this way the scope and power of flash have the best compromise.
The fashion HSS (High Speed Sync) comes as the magic solution to drop below the flash sync speed (1/250 sec) ... thus by failing to indicate the power is extraordinarily weak (lying by omission ?).
Canon councils in the Manual are not really relevant and sufficient to make the most of this extraordinary equipment yet. Beautiful photo and flash lovers go for this information in books (in English) Neil van Niekerk: This is simply unparalleled!
As for the remote flash fires must actually consider this:
- The infrared synchronization device requires the addition of a transmitter STE2 for most Canon boxes ... which means that the slave flash must be in a field of 80 ° to the front of the unit. It is expensive but worth the money you still get the powerful device TTL II.
- Append a radio wave synchronization device ... there at all prices but want to keep the TTL setting suggests a significant investment
In short: An excellent flash of the Canon range. A great power, a recognized manufacturing quality, beautiful color temperature homogeneity. A material that every photographer should have at the bottom of her tote ... because flash is not only used at night but also during the day to achieve an effective fill-in.
