- Tighten Your Grip. The TGA-1 Thumb Grip adds stability to the RX1-series cameras, even when shooting one-handed.
- Hot to Cold Shoe. This grip attaches via the camera’s top shoemount adapter. While it will duplicate the mounting point, the TGA-1’s shoemount does not feature any electronic connections
- Grip Only. While many add-on grips also provide an additional battery slot, this grip does not. It is just a thumb grip for improving ergonomics.
- EVF Compatibility. Since the TGA-1 Grip mounts to the RX1 / RX1R hotshoe, the Sony FDA-EV1MK Electronic Viewfinder is not compatible. However, the TGA-1 has no affect on the RX1R II pop-up EVF.
