Leica M24015 Silver

The Leica M10 Thumb Support is a brass thumb rest that slides into the hot shoe and improves one-handed grip. It costs around $303 to $306 USD, which is a lot for a small piece of metal, but the build quality and finish match the M10 perfectly. It's a solid buy for street shooters who want better ergonomics, but it blocks the hot shoe and does nothing for actual camera performance. If you don't shoot one-handed, skip it.

Performance for a thumb rest is a weird thing to measure. Our database ranks this accessory against actual cameras, which is why the numbers look so brutal. 46th percentile for battery, 34th for autofocus, 23rd for video. None of that matters here. What matters is whether your thumb feels better. And by all accounts, it does. The brass construction gives it a solid, cold feel that matches the M10's top plate. It doesn't flex or wobble once seated in the hot shoe.

The real-world benefit is stability. With your thumb braced against the support, you can hold the camera more securely with one hand. That means less camera shake at slower shutter speeds and a more confident grip when you're shooting from the hip or holding the camera down at chest level. It's a small change that makes the M10 feel more like an extension of your hand. Just don't expect it to improve your autofocus. The M10 doesn't have any.

Compared to actual cameras in this price range, the Thumb Support is a hilarious mismatch. The Panasonic Lumix G9 II, Fujifilm X-S20, Nikon Z5, Olympus OM-D E-M1 Mark III, and Canon EOS M50 Mark II all cost more, but they're also, you know, cameras. They have sensors and shutters and buttons. This is a thumb rest. The comparison is absurd on purpose, but it does highlight what you're really buying: an ergonomic upgrade for a camera you already own, not a new imaging tool.

Against other thumb rests and grips, the Leica option stands out for its build quality and brand consistency. Cheaper third-party options might cost half as much, but they often use aluminum instead of brass and don't match the M10's silver finish as well. If you care about keeping your camera looking factory-fresh, the official accessory is the safer bet. If you just want a place to put your thumb and don't care about aesthetics, save your money and buy a generic one.

Let's talk about the elephant in the room. This thing costs around $303 to $306 USD. For a thumb rest. You can buy an entire used camera for that money. You can buy a very nice lens. You can buy a lot of film. But Leica has never been in the business of budget accessories, and the Thumb Support is no exception.

Is it worth it? If you shoot one-handed a lot, or if the M10's minimalist body leaves your hand cramping after a long day, then yes, probably. The brass construction and perfect color match mean it feels like part of the camera, not an add-on. Third-party thumb rests exist for less, but they often don't match the finish or fit as precisely. With Leica, you're paying for the guarantee that it just works. Whether that's worth $300 is a personal call. We're not here to judge. Okay, we're judging a little.

Let's get one thing straight right away. This is not a camera. It's a chunk of brass that slides into the hot shoe of a Leica M10 and gives your thumb somewhere to rest. If you clicked expecting sensor benchmarks and burst rates, you're in the wrong aisle. But if you own an M10 and your thumb has been wandering around the back of the camera looking for purchase, this little accessory might be exactly what you need.

Leica shooters are a particular bunch. We get it. The M10 is a beautifully minimal camera, but minimal sometimes means cramped. The Thumb Support is Leica's own answer to that problem. It's machined from brass with a silver finish that matches the camera body, so it looks like it belongs there. No plastic, no rubber, no third-party vibes. Just metal on metal.

The pitch is simple: better ergonomics, steadier grip, especially for one-handed shooting. That's the whole story. At around $303 to $306 USD, it's also one of the more expensive ways to buy a small piece of metal. But Leica owners are used to that math by now.

If you shoot on a tripod, use a flash, or never felt like the M10 was hard to hold, this accessory is not for you. The hot shoe blockage alone is a dealbreaker for anyone who relies on external lighting or viewfinders. And if you're the type who upgrades camera bodies every few years, spending $300 on a thumb rest that only fits the M10 is a tough pill to swallow.

Instead, look at a half case with a built-in grip, which can improve ergonomics without blocking the hot shoe. Or just save your money. The M10 is already a beautifully balanced camera for two-handed shooting. If you don't shoot one-handed, you probably won't notice the difference this accessory makes.

For the M10 owner who shoots one-handed, street style, or just wants a more secure grip, the Leica Thumb Support is a genuinely useful upgrade. It's well made, looks like it belongs on the camera, and does exactly what it promises. The brass construction gives it a premium feel that matches the M10's build quality, and the hot shoe installation means you can remove it in seconds if you change your mind.

For everyone else, this is a very expensive way to solve a problem you might not have. If you shoot on a tripod, use a flash, or never felt like the M10 was hard to hold, skip it. The money is better spent on a lens, a bag, or literally anything else. But if your thumb has been searching for a home on the back of that beautiful brass body, this is the answer. Just don't expect it to improve your battery life.
