FotodioX Pro Thumb Grip Type D for Mirrorless Digital Cameras, Black Review

The FotodioX Pro Thumb Grip Type D is an inexpensive accessory designed to improve handling and stability on mirrorless cameras. It mounts to the hot shoe and provides a raised platform for your thumb, creating a more secure three-point grip that can reduce camera shake and make longer shooting sessions more comfortable. At $18, it's a straightforward ergonomic upgrade that's particularly useful for smaller or lighter mirrorless bodies that lack a pronounced grip.

This Type D model features a black finish and a simple slip-on design that doesn't require permanent modification to your camera. It's a budget-friendly option for shooters who find their mirrorless camera slippery or fatiguing to hold, though it does occupy your hot shoe, which means you'll need to remove it when using an external flash or other accessories that rely on that mount.
