Hi,
I recently acquired 4 Einsteins and a Cyber Commander control system for use with my Canon 7D to take indoor action shots (amongst many other things).
Of course, the challenge here is that the x-sync speed of the Canon 7D is 1/250, although I have successfully taken photographs at 1/320 without the dreaded black bar.
The Canon 7D (and other models) do have an "HSS" setting - High Speed Sync, which as I have read on other posts may have limitations. However, because the camera will be tripod mounted and, almost universally, a fixed distance from my subjects, I believe that this setting might be acceptable.
To the question at hand:
I have mounted the Cybercommander device on my hotshoe and the Canon "Flash Control --> External flash func. setting" menu displays the error message "This menu cannot be displayed. Incompatible flash or flash's power is turned off."
I have read through several board posts here and on various sites and have taken the following diagnostic efforts:
I have checked the built-in flash controls and those work correctly. I have also checked the micro-switch and it is working correctly. I have disabled Live View. I have ensured that the CyberCommander device is firmly attached to the camera.
I can fire the Einstein lights using the Canon "Built-in flash func. setting -->Flash mode = E-TTL II" and the "Shutter sync." mode of 1st curtain and 2nd curtain are available, however HSS is not available.
It is entirely possible that I do not have the correct combinations of settings to try the HSS mode, however a good couple of hours reading through the 7D manual and browsing a fair amount of web content have left me without a solution.
Any help you might provide would be appreciated.
Thanks!
Lief
