The CXV-FX9 mounts directly to the back of the Sony PXW-FX9, as an alternative power option to the Sony XDCA-FX9. The milled aluminum product inserts into the battery slot of the camera and also attaches into the top of the camera (with included screw hardware) to provide a secure platform for mounting v-mount batteries directly onto the FX9 camera. It has a 19.5v DC output with a visual low battery warning LED and a 4-pin XLR DC input for hotswapping between external and on-board power. In addition, it’s equipped with two powertaps to power additional accessories. A USB firmware update port on the rear ensures future compatibility with camera firmware updates.

Paul Ream from extrashot gives the Core SWX Sony FX9 Power Solution the thumbs up!

Sony’s new FX9 is an impressive piece of engineering. Combining the latest design of full frame, high resolution sensors with a traditional camcorder form factor, the FX9 can capture beautiful shallow DOF footage with an impressive 15 stops of dynamic range. If there has been one outstanding criticism it has been related to powering the camera with proprietary batteries and an unusual PSU voltage of 19.5Volts. There are competing solutions to adapt the FX-9 to use professional V-Lock batteries and Paul Ream from Extrashot thinks he has found the best on the market; it’s from Holdan’s manufacturer - CoreSWX.

Sony FX9 Accessory Guide

There is no doubt that the Sony FX9 is a tremendously significant camcorder and as a new decade begins Holdan’s manufacturers are beginning to ship some fantastic new accessories to increase its already impressive capabilities. Power up There will be a few V-lock adaptors for the FX9 in the coming weeks, but Core SWX are confident their CXV-FX9 is the best option. It has a low battery warning LED, and XLR input to allow for hot-swapping between external and onboard power and being made of aluminium it’s more robust than plastic alternatives. As for the weight, 544g still isn’t heavy and most users prefer it to provide a better-balanced rig.

Pure Power - adding V-mount batteries to the FX9

The FX9 ships as standard with a 35Wh Sony BP battery. For many users, their first thought will be how to use high capacity broadcast batteries for all day shoots. Sony offers an all-singing extension unit, the XDCA-FX9. As well as offering a battery mounting plate, it’s a true expansion system, delivering functionality such as 16-bit RAW output, wireless audio support and network capabilities. For many, this expensive add-on will be hard to justify.

Core SWX Expands European Distribution Network
