TL;DR: If you wanna save a ton of cash, look at the Haoge THB-M10B Thumb Rest for Leica M10. It's about $45 and hits that sweet spot between quality and price without blocking the dial.

Honestly, i get the hesitation. Leica gear is expensive and sticking a $15 piece of mystery metal on it feels... wrong? I've been there. In my experience as someone who has handled many M-series setups, you gotta be cautious about the fit. If a grip is too loose, it puts weird leverage on the hot shoe which could actually damage the electronics inside over time. I mean, its not likely, but its something to consider.

I would suggest checking out the JJC TA-M10 Thumbs Up Grip. You can usually find it for around $25-30. It’s definitely more budget-friendly than the boutique ones mentioned earlier. The JJC version actually has a little silicone padding where it meets the camera body to prevent those scratches youre worried about. Just make sure to get the one specifically for the M10 cuz the dimensions are different from the older M240.

But yeah, if you want something that feels a bit more "premium" without the $200 Leica price tag, the Haoge THB-M10B Thumb Rest for Leica M10 is basically the industry standard for budget shooters. Its CNC machined and feels way more secure than the super cheap generic ones. Just be careful when sliding it in—dont force it! gl with the street sessions! 👍

> I’ve been looking at the official Leica brand vs. Match Technical’s Thumbs Up, but there's a huge price gap. I’m worried about third-party options potentially scratching the finish or being too loose in the hot shoe.

honestly, i've tried a bunch of these over the years, and if you want that rock-solid feel without the wobble, just go for the Match Technical Thumbs Up EP-MX for Leica M10. basically, the solid brass construction is wayyy better than the aluminum ones like the Haoge LH-M10B Thumb Grip. in my experience, the cheaper ones eventually get loose in the hot shoe, and that's when you get the dreaded finish scratches... so yeah. the Match Technical one has these little silicone inserts that actually protect the body and keep things tight. plus, it’s angled perfectly so it wont block ur shutter dial at all. seriously, it's worth the investment for an M10. gl!

Hmm, I've had a different experience with those hot shoe grips. Honestly, I'm not totally convinced a thumb grip is the absolute best fix for the fatigue you're feeling after an hour of street shooting. I used them for a bit but found they kinda mess with the sleekness of the M10 and sometimes get in the way of the dial, even the expensive ones.

Before you spend a bunch of money on the premium brands or risk a cheap one that might wobble, I'd actually suggest a different approach. Sometimes a solid baseplate or even just changing how you use your neck strap can make a way bigger difference in how the weight sits in your hand.

Quick question tho—what lenses are you usually rocking? If you're using heavy glass like a Noctilux or a big Summilux, a thumb grip might just shift the strain somewhere else. Also, are you looking for more stability while shooting or just a better way to carry it? Just curious cuz it might change what's actually helpful. gl!

Oh man, I totally feel u on the hand fatigue—the M10 is basically a brick after an hour lol. Just found this thread and wanted to share a quick horror story. I bought a realy cheap generic grip once, and because it didn't have any padding, it actually wiggled enough to scratch the finish inside my hot shoe. It was heartbreaking!!

Here's what I suggest for safety:
- Look for grips that include small rubber bumpers. This is CRITICAL to prevent that metal-on-metal rubbing.
- Check the tension. In my experience, the mid-range boutique brands have much tighter tolerances than the super cheap ones.
- Honestly, just make sure it has a 'cutout' design so you don't faff around with the dial.

I know folks already mentioned the premium boutique options, but basically, dont risk ur expensive camera on a $10 part. gl! 👍

So, if you’re wondering why there's such a massive price jump, it’s mostly about the physics and the materials used. Brass grips, like the Match Technical Thumbs Up EP-MX, are basically designed to match the density and weight of the Leica body itself. Aluminum ones are lighter, but they can feel a bit "chintzy" and don't always absorb vibrations the same way.

The real secret to how they fix fatigue is the leverage. Without a grip, your hand is constantly doing a "pinching" motion to hold that brick steady. But with a thumb rest, you’re creating a secondary contact point that shifts the weight onto the ball of your hand. It completely changes the center of gravity, especially if you're rocking a heavier lens. Just make sure you look for one with a tiny rubber bumper on the back—that’s basically the key to preventing those scratches people worry about, tbh.
