Honestly, that missing thumb lever on the Q3 drives everyone crazy when they switch from an M. In my experience, you really dont need to spend Leica prices to get that solid feel. Ive tried many generic ones and settled on a combo thats survived some pretty rough conditions. For Iceland, you want metal that wont rattle.

• Haoge THB-Q3B Thumb Rest for Leica Q3 Black Aluminum
• This thing is CNC machined from 6061-T6 aluminum. The fitment in the hot shoe is tight, no wobbling at all.
• Haoge HG-Q3 Hand Grip for Leica Q3 with Arca Swiss Base
• Since youll probably be using a tripod for those waterfalls, the integrated Arca plate is huge. It adds just enough depth for a secure one-handed hold. Youll spend way less than $150 for both. Save the rest of your budget for a good pair of liner gloves... trust me, you gonna need them in that wind.

I was in your shoes before a big trip to the Alps. Spent my whole budget on the camera and needed a cheap fix. I ended up with the Haoge HG-Q3 Camera Hand Grip and their Haoge THB-Q3B Thumb Grip. Honestly? I never felt the need to upgrade. They survived freezing temps perfectly. Better to save that extra cash for a tour or something while youre in Iceland.

Late to the party but ive been super satisfied with my current setup for the Q3. If you want that M feel without the Leica tax, there are a couple of technical winners.

• Match Technical Thumbs Up EP-SQ3 Black is basically the gold standard. It is machined from solid brass and the fit is incredibly tight with zero wiggle. It really feels like part of the camera body.
• For the lower grip, JJC HG-Q3 Metal Camera Hand Grip for Leica Q3 works well because it adds an integrated Arca-Swiss plate. It is a total life saver for quick tripod swaps in windy places like Iceland. The tolerances on both are spot on. Im really happy with how the ergonomics turned out. It feels just like an M now but with the Q speed. No complaints at all about the build quality.

My buddy told me the exact same thing last week. Guess he was right lol.

To add to the point above: I would suggest being a bit cautious with the cheaper clones if youre headed to Iceland. Cold temps and high humidity can really mess with fitment tolerances on lower-end gear. I think you might want to consider the IDS Works Foldable Thumb Rest for Leica Q3. It actually folds out like the M10-D lever, which really helps with that muscle memory youre missing from the M system. Just make sure to check the tension screw periodically... you dont want it flapping around in those high Icelandic winds. For a solid bottom grip, the IDS Works Modular Base Plate for Leica Q3 is probably the most reliable pick for a trip like this. Tbh, some generic grips have slight misalignments with the battery door, and when your fingers are frozen, thats the last thing you want to deal with. The IDS gear is CNC machined to a much higher standard than the basic mass-market stuff. It might push your $200 budget right to the edge, but for a big trip, I think its better to get the kit that wont fail or scratch your top plate. Just my two cents.
