I’ve been using Hot Shoe Extension bars for a while now, because they’re amazing! They give you the ability to add a lot more things to you camera, which can really come in handy often when you’re using your dslr.
These cheap extension bars allow you to add pretty much whatever you want to the top of your dslr. For instance you could add a shotgun mic, flash, led video light, external audio recorder or even a wireless mic set.
I highly recommend them!
