The main reason I picked up the V6 II, was to try out the AF-Assist feature.
It is nice that it's now an integrated feature, but I would like to have seen it be a proper AF assist light, like the one in ALL other strobes.
All other strobes that have an AF assist light throw out a pattern of light, not just a bath of light.
The pattern helps the camera focus much quicker since it's not so much the amount of light, but the pattern that helps the AF sensor in the camera focus on the target.
Maybe in the V6 III, you can add a proper contrast detect pattern that gets projected by the AF Assist lamp.
