    @Drew - You can just mount it on top of any 15mm base. Imagine mounting a camera to a shoulder rig. You would do the same, except it would already be in a cage.

    Has anyone figured out a good base plate solution for the Armor II a7 cage?? It's the only failure of this cage

    @The Brand University - I honestly don't think the A7s cage would work on the A7RII. But if you like Varavon products, they are already working on an A7RII Cage: httpss://]

  6. Is there any word on if the cage will fit the a7r2? This seems like a great solution, but Sony is turning over cameras so quickly these days, it may not make sense to get something so snug.

    @Patrick - I personally make my own wires if I want it a custom length. Just find the right adapters, basic wires, and solder. If you don't want to make one, you can use a really small project box to hold all the excess wiring. Just wind it up tight and put it in a small box, then cut two holes for the wires to go in and out.

    Yo Emm! Just picked up the battery tpower. I'll be mounting it on top of camera. Any tips on managing super long wire?

    @Pete - I'm not sure what the battery Amps are rated at, but I think a monitor would be fine. An LED would probably draw too much power from the battery though. If you're looking for a single battery solution to power multiple devices, I would have to suggest looking into those V-Mount power distribution boxes.

    Hey Emm,

    This power solution looks very convenient - is it possible to split the DC out to power a monitor, and small LED? Was wondering if that would tax the battery and or multiple devices.

    @Cagliostro - I think you're overthinking something pretty simple, and people have been using this kit for almost a year now. Maybe for you to feel safe though, just look into another product.

    Thank you addressing my concerns, but from your answers I'd have to assume they took the appropriate measures to prevent damage. It'd be nice if they confirm the dummy battery has a regulator, or if they did testing beforehand to confirm damaging the internal components is impossible as opposed to improbable, especially when they are marketing their product specifically for use with the A7s. I was ready to get 3 batteries when I noticed the voltage discrepancy.

    @Cagliostro - I doubt it will be any problem. Example: The Canon DSLR uses 7.2V batteries but the AC adapter with dummy battery is over 8 volts. The Sony is probably the same. Even though the battery is 7.2V it can probably accept more. Secondly, the dummy battery for the Varavon kit probably has a regulator built in. Most of these do. They even sell cables for D-Tap on a V-Mount to Sony which is connected directly to a 14V V-Mount battery. The adapter has a regulator built in to drop the 14V down to a safe level and sometimes this has an internal fuse too, in case it exceeds the safe voltage. I just don't forsee any issues.

  14. Cagliostro

    The battery voltage for the A7s is 7.2V, not 7.4V; this battery can only be set to they guarantee that this difference in voltage won't damage the A7s' components? I know it's a small difference, but how do we know we can use this battery safely?

    @AMPM - I don't know of an Atomos cage that will allow use of the stock Sunhood. I know you can get an aftermarket 10" sunhood and place it over most cages.

  16. AMPM

    Great review emm thanks. Does it look like there's any clearance on the Shogun cage to fit the Atomos Sun Shade?
