The rumors are true. I've heard through the grapevine that a cheaper DSLR cage would be made before the year ended. This appears to be that cage. [Thanks Serge]. This particular cage works mainly on Canon DSLR cameras giving access to the card slot and battery door. Not tall enough to support a battery grip.
It's a fair option to add a bracket around your camera to help mount additional accessories, but i'm a bit sketchy on the way the seperate parts are mated together. Doesn't look like the best method to use when joining two parts that thin - dare I say 'flimsy'? I personally think the starting price is also too high, especially when you could get a better stabilizer out of the Alzo cage found here: https://cheesycam.com/alzo-dslr-accessory-cage/.
We'll have to wait to hear more and see some reviews, but this particular new Canon DSLR cage can already be found via eBay (click here).
