This optional and exclusive vertical grip for GFX, medium format digital cameras is designed for advanced users or professionals. Most grips and cameras don’t have unified operations due to the different cross-section of shapes of grips and the different layout of shutters or other buttons. However with the VG-GFX1, the main buttons' layout and form were adjusted to the camera, and unified operability (the same location, form and usability) vertically and horizontally was achieved. This grip offers reliability, stability, and comfort when choosing the right moment to take pictures.
