The 622s have Supersync, which is a whole-burn technique with no control on initiation. So, does PW adopt an adequate frequency and abandon all previous gear, or try to improve speeds by trimming programming? This is becoming a problem with ever-faster camera processors and timing-intensive flash syncs. Their chosen radio frequency has a very low reolution capability = slow data transmission. Both devices have their role, and PWs have been a godsend for photographers. I should not have made it a A versus B argument. However, the 622 has no facility for updating the firmware.Ĭlick to expand.You are right. And 1D X, although there is instability with ratios. Then there is the 5DIII compatibility for months. Are any of these not handled by PWs? Some are handled better than the 622s, I understand. I selected items from the Contents of TOYUG that showed the significant capabilities of the 622s. But, the YN-622 requires a different way of thinking. PWs are well behind in capabilities by today's standards.īy, the way, Phil, I recognised that your perceptions were influenced by the capabilities of PWs. Nevertheless, I have confirmed that the 622s handle Canon meticulously. PS I have used Canon cameras and Speedlites for a decade, and was using E-TTL and FEC long before flash control menus appeared. A good grasp of Canon flash technologies is a pre-requisite for using the YN-622C, as it is designed to handle Canon protocols by radio, with all Canon's limitations. The camera menu (see p.11-13 of TOYUG) can enable Wireless mode and set a firing group of A:B and ratio, and this is applied to the mounted 622.īut, this is all Canon stuff, not YongNuo. It is one of the three ways FEC can be set - on-camera. ![]() (The camera determines which flavour, not the flash or 622.) Put the flash into E-TTL mode, and then adjust FEC using the camera's FEC button. ![]() The "no compatible flash" does not appear as there is a compatible "flash" mounted - the 622.īut that is irrelevant for the present question.Įven a non-menu-controllable Speedlite can be used for E-TTL. The 622 programming looks after whatever is out there. The camera menus interact with the 622, and nothing else. If there is an on-top flash, it is the flash head component of the Master. The YN-622C when on-camera is a fully-compatible Master flash controller unit.
