NP-FZ100 Dummy Battery / Coupler ✨ Retail Price: ¥6480 Compatible with Sony mirrorless cameras and other similar models! It's D-tap, so I was using it by drawing power from a V-mount battery, etc. I used it with my Sony FX-3 for about a year, but I'm selling it because I bought a different one due to a body upgrade. There were no problems with its use, but please understand that it is a used item before purchasing.
