Not everyone needs a cage for their camera but those who do video work will appreciate the attachments you can add to your camera. Those who primarily record themselves will benefit by getting a cage for their a6400 or any a6xxx because the mic jack get’s in the way of the screen, you can counter this by purchasing a hot shoe mount to attach.
Furthermore, you can attach lights and 4k monitors if you’d like; the possibilities are endless until you run out of screws that is. My favorite attachment next to the hot shoe mount is attaching my light from aperture! i suggest looking into the cage if you are a videographer. Let me know how you like it!
If you decide to purchase any of these items head over to the My Gear tab and use my link if you’d like. Thank you.
