Meike makes good affordable grips for Sony cameras and I have never once had an issue with mine for the Sony a7RIII. Meike’s grip for the Sony a6600 looks to have very similar features to mine with:
- Use high-quality rubber, comfort to hold
- Use 2.4GHz wireless channel and FSK signal mode can more effectively ensure speed, distance and stability.
- Vertical shooting function, the best choice for portrait photography
- Suitable for Sony A6600 Camera
- 2pcs NP-FZ100 Lithium batteries can be put into the grip, the max distance for remote control can reach to about 100m.
