I first started vlogging with a GoPro Hero3+ Silver. With this I did videos without any audio commentary. I just used music. When I upgraded to a GoPro Hero5 Black, I was able to add audio commentary through its microphone. This was a great improvement for more versatile vlogs. To improve the audio I purchased the GoPro Hero5 external mic adaptor and the RØDE VideoMicro, which is a great, inexpensive shotgun microphone. I modified the frame of the Hero5 using this guy’s YouTube tutorial on how to mount the attachment.
I recently purchased a new camera, the Panasonic G85. I am excited to start using it!
