Core SWX PTC-A7SR Reviews

Beware

By Yuling
Rated 1 out of 5
Date: 2017-05-24

Plugged it into a Core V mount battery. Worked initially the first time I powered on my a7s II, but the second time I tried it I heard a loud pop and feared for the worst. I initially thought my camera had been fried, but luckily it was still working when I tested it with an a7s battery (although the date and time had reset) What had fried was the regulator. I'm not an electrical engineer so I'm not sure what exactly happened, but when I took apart the dummy battery, it looked liked the cables connecting to one of the terminals had exploded. My advice- don't use this power regulator, especially since the circuit board is inside the dummy battery and hence inside the camera when in use. If something goes wrong like it did when I tried it, an externally placed regulator (like the Indiepro one) would be better- at least the risk of damaging the camera would be less.

Works great with a W-series battery Sony cam

I use this to power my a6000 from a gold mount battery. Wish it was a bit longer. Also wish there was a pass through for the cable on the battery grip for the a7r II, but works as advertised. Keep the battery in my cargo pocket and it works, if not a little tight. A rig mount or hip holster/backpack for the battery would be better.

Potentially a little loose

I'm not sure if it's my battery or this cable, but when I plug it in the connection is a tiny bit loose. It happens to be that when my battery is mounted on the camera, the p-tap is on the underside of the battery so sometimes gravity just pulls the connection out, which is a problem because it's powering my camera! I have to strap it up with bongo ties to keep it in.

Long life battery

Stop unnerving yourself with the short life batteries in Sony a7 S/R series. This useful cable can be attached to several D-tap power supplies available. Keep cool and enjoy your videos.

WARNING!

I should have read the other reviews about this cable. It is true, there is some kind of power issue. The cable is not properly regulated as stated in the description. Powering the Sony A7s camera VIA d-tap power with this cable will cause nasty flickering and rolling shutter. Especially while filming at 60fps in NTSC mode with proper shutter speed and exposure set correctly. Do not buy it. Learn from my mistake.

Generates flicker in my footage

By Long

It seems like the voltage is not well regulated and I am getting flicker in my footage when powering my camera through D-tap. I have done several tests with and without this battery adapter in the same environment and I could see some subtle lines in my video files whenever I use this cable. Very disappointed.

Does this work with Sony A6400? Because I use the same battery for A7 R ii and A6400 (NP FW50). Thank you.

question

Does this have reverse polarity protection?
Asked by: Yuling
NOT as far as I know. Never had an issue with the cable though. Just make sure you dont force it into the ptap Connection
