A:AnswerYongnuo makes a radio receiver that works off of your existing Nikon or Canon radio master flash, that works very well with these. (I use two set ups just this way with my camera.)
Its Yongnuo part # YNE3-RX.
PLEASE NOTE: In this scenario, you must have either a Nikon, Canon, or Yongnuo Radio Master Flash. (I use my Canon 430EX-IIRT as master.)
A:AnswerI would like to say no since a Sony a6000 is not a DSLR and HDSLR camera. A Sony A6000 is classified as a Mirrorless camera. My camera is a Canon Ti7 and it works fine. I think this DF4000N was originally made for Nikon and Canon DSLR and HDSLR cameras. If this model was made specifically to a Sony camera the Serial number would have an S after a tack example...DF4000U-S OR DF4000U-NC. I apologize for not being able to test this universal adapter with your camera. I also did a little bit of research and Fry's sells a camera shoe adapter. One of the buyers gave it a one star review since they were not confident in the products ability since it does not click to the camera like normal add-ons. I am guessing that you could get this adapter from Fry's and try this actual DF4000N.
A:AnswerIf you visit the manufacturer website (Insignia) you can download and print the manual. Once downloaded, you should be able to copy and past the text into a text editor and change the font size to your liking.
A:AnswerIt's not a flash, but an LED light array that's either On or Off. It can physically mount to a hot-shoe on a camera, but it's not a hot-shoe controlled light.
