My YN565EX performs as expected on and with my Canon 7D. The YN565EX does not have high speed sync and cannot function as the master flash for the Canon wireless system but the lack of those two features was expected. Otherwise, the YN565EX seems to work well with the 7D. In fact, the easiest way to describe the YN565EX is that it is almost a Canon 580EX II.
While playing around with the YN565EX and Canon 580EX II, I realized that the YN565EX is perceptibly louder and sounds a bit “harder” as well when it flashes. The sound and volume is not particularly objectionable but is definitely noticeable when the two flashes are activated side-by-side. On the positive side, I found that the YN565EX recycles a bit faster than the 580EX II. With one flash in each hand, I manually triggered them at the same time and watched the ready lights. Both flashes were in manual mode and flashing at full power. The YN565EX ready light always lit first – even after swapping batteries. This may be nothing more than an indication that the YN565EX ready light comes on at a different point than does the 580EX II; even so, it is sort of reassuring.
To get the (first) photo of the 7D with mounted and flashing YN565EX, the camera was turned off and the flash was set to optical trigger (SL 1) at lowest power (1/128). The picture was taken with my G12 using its manual internal flash set to minimum power. A YN460-II, also in SL 1 mode, was placed outside my homemade light tent as the main light. The YN565EX (and YN460-II) work well in both SL 1 and SL 2 (ignores Canon pre-flash) modes.
On the 7D, the YN565EX works as expected. Again, there is no high speed sync and the YN565EX cannot be used as the master flash in Canon’s wireless system. The YN565EX zooms with the 7D lens (15-85mm Canon in this case) and indicates the true focal length (not the 35mm equivalent) on its display.
Off-camera, the YN565EX could be triggered wirelessly by the built-in flash of the 7D or by the 580EX II mounted on the 7D. Exposure compensation on the 7D was passed along to the YN565EX. Using the 580EX II mounted on the 7D as the “A” flash and designating the YN565EX as the “B” flash, the flash ratios could be set in the 7D system.
The YN565EX and RF-602 were used to make my most recent PAW (and many more that day) so this combination works well together (shame on Yongnuo if they did not!).
My intention is not to use the YN565EX mounted on the 7D but as a second flash with Canon’s wireless system or as a manual flash to be triggered by my Yongnuo RF-602 wireless triggers. The YN565EX seems to meet my requirements and expectations.
Next, the YN565EX and the Canon G12 …
