The Nikon Z f-GR1 Extension Grip (sold separately) is designed specifically for the Nikon Z f mirrorless camera. Constructed from lightweight and strong aluminum, the Z f-GR1 grip matches the classic design of the retro-styled Z f and is finished with the same comfortable artificial leather material as the camera body, giving it a consistent appearance. Front and rear grip surfaces provide a firm, ergonomic hold, even when the Z f is used one-handed. The Z f-GR1 grip is equipped with a standard threaded ¼ type tripod attachment hole, and the base of the grip is compatible with the Arca Swiss standard for easy mounting on most tripod heads without additional accessories. The Z f’s battery and memory card compartment remains accessible with the grip installed. Dimensions of the Extension Grip are approximately 5.8 (l) x 2.2 (w) x 2.8 (d) inches, and it weighs approximately 4.3 ounces.
