Originally posted by THoog Don't use the wireless flash option on the camera. The YN560s aren't smart enough to understand the signal it tries to send, and are triggering at the wrong time. In S1 mode, they trigger as soon as they see ANY flash from the camera, and in S2 mode, they trigger on the second flash, thinking the first is a TTL preflash. Either way, the flashes are triggering early, with unpredictable results.
I switched to manual focus, assuming that there wont be any pre-flash that confuses the speedlights. Let me know if my understanding is wrong. Also, if that is the case I didn't understand why its behaving weirdly below 1/32 only.

I came in to suggest getting the 560TX controller. It allows you to control settings on either or both flashes from the camera wirelessly and sync without using the on board flash as a master. You can group the flashes together so both use the same settings or separate them so each flash is set individually. It's a great addition for $40 (from B&H). I use the Nikon version and it works fine on my K-30. And it lets you do stuff like this:
I have strobes and am using a controller already.. basically I want to use these speedlights for fill in or background. Other than that, TX costs around 70 - 80 $ in my country.. it will be a further waste considering that I already spent 180$ on these flashes.
