I was looking around for hacks to add synchronized audio recording using external mics on the Sony a5000 and a5100, and I found two methods. To make this clear, these methods do NOT require you to synch the audio in post, or at least not in the traditional sense. I will start with the method that is easiest, but requires the use of a cellphone for recording. Note that the only camera that I have seen this work with is the a5100 in this video -- it might NOT work with the a5000. Also, it probably needs a phone with enough processing power to get it done. How powerful? I don't know.: "How to use external microphone with sony a5100", posted Oct 17, 2019, by"Pin2Tech" [length 8:39] "" The second method is a hardware hack, adding a microphone jack to the camera. The method is confirmed to work with both the a5000 and the a5100. It is difficult and I do NOT advise attempting this is you are not skilled with fine quality soldering and working with digital electronics in general. You will need to watch the following two videos if you want to keep the internal mics as well as the external mic: "A5000 external mic hack and more! ***Do this at your own risk!!***", Posted Mar 21, 2019 by "Rosario Marino", [length 28:44] "" "A5000 external mic hack MK2!!", NOTE: Must also view previous mod for camera disassembly Posted Apr 19, 2019, by "Rosario Marino" [length 11:36] ""
