TL;DR: Lensmate Thumb Grip for Fujifilm X100VI is king for dial access. Pair with Peak Design Leash Camera Strap Black. Super happy with this setup, no complaints at all.

Honestly you dont need to spend a fortune to keep that camera safe! These budget picks are amazing and save you money for more ramen in Tokyo.

• JJC TA-X100VI Thumb Grip Black Aluminum - fits perfectly without blocking the dials.
• VKO Black Cotton Camera Wrist Strap - super soft and basically indestructible. Youre gonna love the VI tho, its a total beast!

Im also terrified of dropping mine tho... torn between these:

• Haoge THB-X100V Metal Thumb Grip is cheap but watch the finish
• Gordys Camera Straps Leather Wrist Strap is sturdy but kinda stiff

Like someone mentioned, the Lensmate is a solid choice but if you're really worried about reliability and that premium feel, Match Technical Thumbs Up EP-2V for Fujifilm X100V is probably the sturdiest one out there. It's machined brass so it wont bend or snap, and the fit is incredibly tight so it doesn't wiggle. It's expensive but feels like a tank compared to the aluminum ones. For the strap, if you're worried about dropping it, the Peak Design Cuff Camera Wrist Strap Black is objectively more secure than a standard loop. It has a magnetic lock that cinches down on your wrist if the camera falls. If that looks too modern, Clever Supply Co Skinny Anchor Strap is a great middle ground. It uses the Peak Design anchors for safety but gives you a nice leather look that fits the Fuji aesthetic better. Both are super solid options depending on if you want pure function or a bit more style while you're wandering around Shinjuku. Just make sure whatever you pick feels right in the hand before your flight!
