Quick answer

The SquareHood Thumb Grip for FujiFilm GFX100RF is a solid choice if you want one-handed stability and uninterrupted access to the AEL/AFL button on Fujifilm's medium format fixed-lens camera. It uses anodised aluminium or solid brass with silicone padding, and it is designed specifically for the 100RF rather than adapted from another model. If you rarely shoot one-handed or prefer a bare body, you can skip it.

Why a dedicated thumb grip matters on the GFX100RF

The GFX100RF is a medium format camera, so even a compact body carries more weight and torque than an APS-C X100-series camera. A thumb grip adds a rear anchor point that lets you hold the camera in one hand with ease and comfort, while still allowing unobstructed access to all the controls. That matters most when you are shooting at eye level for long stretches, walking with the camera at your side, or making quick adjustments without lowering the camera.

The SquareHood Thumb Grip for the 100RF is made specifically for that body. The silicone padding on the back side protects the camera finish and adds friction, and the silicone button is positioned to access the AEL / AFL button. That button access is the detail that separates a purpose-built grip from a generic add-on: you keep the rear controls you actually use.

Material and colour: what changes and what does not

The grip is available in anodised aluminium or solid brass, with colour as the option type. Both materials are rigid and add a planted feel, but they differ in weight and how they age. Aluminium keeps the overall setup lighter, which is usually the better match for a camera you carry all day. Brass is denser, so it shifts the balance slightly and develops a patina over time if you like that look.

Colour is a handling decision as much as an aesthetic one. A black grip blends into the body and draws less attention; silver or brass stands out more. If you shoot in public and prefer a low-profile rig, black is the safer pick. If you want the grip to feel like a deliberate part of the camera, brass or a contrasting finish is the more satisfying choice.

Fit guidance for the GFX100RF

This grip is made for the FujiFilm GFX100RF, so it seats against the camera body without blocking the controls. It is not a universal grip and it is not listed as compatible with other GFX bodies or the X100 series. If you own an X100V, the SquareHood Thumb Grip for Fuji X100V is the correct fit instead; the two are different products with different body profiles.

Before buying, check two things: that you are comfortable with a rear thumb rest changing how your hand sits, and that you do not rely on a rear accessory that would conflict with the grip's position. The grip is designed to leave the controls unobstructed, but your own hand size and grip style still determine whether it feels natural. If you have large hands or a heavy lens-forward hold, the added anchor point usually helps; if you shoot primarily from a tripod or with a cage, you may not need it.

Trade-offs to weigh before you buy

A thumb grip adds a small amount of bulk to the rear of the camera. That is the point, but it also means the body no longer sits as flat in a tight bag. If your bag is already snug, measure the added depth or plan to remove the grip for transport. The grip is also a fixed accessory: it does not fold away, so it is always part of the camera's footprint.

Price is another honest consideration. At USD 79.27 (catalog comparison price USD 129.95), the 100RF grip sits above the X100V version at USD 45.47 (catalog comparison price USD 64.95). The difference reflects the larger body and the materials involved, not a difference in function. If you already own the X100V grip, do not expect it to fit the 100RF.

Decision rules for the GFX100RF thumb grip

  • If you shoot one-handed: Choose the SquareHood Thumb Grip for FujiFilm GFX100RF in anodised aluminium. It adds a rear anchor point without blocking controls, which is the exact use case the grip was built for. Best match for walk-around and eye-level shooting.
  • If you want a heavier, patina-friendly feel: Choose solid brass. It is denser than aluminium and changes the balance slightly, so try it before committing if you are sensitive to camera weight. Pick brass for feel and ageing, aluminium for lighter carry.
  • If you own an X100V, not a GFX100RF: Buy the SquareHood Thumb Grip for Fuji X100V instead. The 100RF grip is made for the 100RF body and is not listed as compatible with the X100V. Match the grip to the body; do not adapt across models.
  • If you mostly shoot from a tripod or cage: Skip the thumb grip. The added rear bulk and cost only pay off when handheld stability is the limiting factor. No handling gain if your hands are not holding the camera.
