Canon R6 II Compatible Flash Guns

[JoeTheSnowPlowGuy]

I have a Sigma EF-530 DG Super flash gun. I know it's not fully compatible with the R6, but is there an adapter I could use, or is it able to be used with limited capabilities?

As long as it fires. You may not have ETTL but if you have time setting up a flash exposure is pretty basic. You can take a shot with a white piece of paper, study the histogram and tune the exposure. When I shot weddings and did not have time to set up. I followed Neil van Niekirk's teachings and used that method even with ETTL. Anything white. Dresses, shirts, collars, cuffs, purses, etc. Just tuned the EC.
