saw this a few hours back and honestly its a tough spot. unfortunately a lot of the popular gear is way overpriced for what you actually get. before i dive into suggestions though, what kind of backpack are you actually bringing? that really changes how you should organize your gear for those 20k step days. if you want to fix that tripod situation without blowing your whole budget, i have a few thoughts:

• Ulanzi Zero Y Lightweight Travel Tripod is a solid carbon fiber option. its much cheaper than the name brands but i had issues with the center column being a bit finicky. still weighs almost nothing tho.
• Benro Slim Carbon Fiber Lightweight Travel Tripod is another one to look at. i found it wasnt as rigid as i expected in the wind but for city shots in tokyo its miles better than a heavy generic one. basically you gotta decide if you want absolute stability or something you wont hate carrying.

Late to the party but unfortunately most people overlook technical reliability for flashy gear. I've had issues with generic chargers failing mid-trip and it ruins the experience. For an a7iv, you need components that match the body's internal specs or you're just asking for a technical failure in the middle of Shinjuku. Since you're worried about the battery mess and safety, you really need to look at power management and data integrity. I'd suggest these:

• Nitecore USN4 Pro Dual Slot USB QC Charger for Sony NP-FZ100
• This thing handles Quick Charge 2.0 and gives you real-time data on battery health and voltage. It's much more consistent than the slow internal charging Sony provides.
• Sony TOUGH-G series SDXC UHS-II 128GB V90 Memory Card
• Most cards have those flimsy plastic ribs that break off in the slot. These are monolithic and 18 times more bend-resistant. Reliability matters when you're shooting once-in-a-lifetime stuff.
• Peak Design Cuff Camera Wrist Strap CF-AS-3
• This uses the V4 anchors rated for 90kg of force. If you hate neck straps, this is the mechanical fail-safe you need so your camera doesnt hit the pavement if someone bumps you in a crowd. It's honestly a shame to see people drop big money on a body then use cheap cards or chargers. Get the power and data management sorted first so you arent stressing about technical failures while trying to enjoy the shrines... its better to have a sore wrist than a shattered sensor because a generic component failed.

• Peak Design Slide Lite SLL-BK-3 Camera Strap with 32mm webbing.
• Think Tank Photo Battery Holder 2 for the 2280mAh NP-FZ100s. itll fix the weight and battery clutter issues.

Regarding what #1 said about the Slide Lite, its a good strap but in my experience, a clip is even better for 20k steps. I use the Peak Design Capture Camera Clip V3 to keep the a7iv on my backpack strap instead of my neck. Also, check out the SmallRig NP-FZ100 Camera Battery Charger Case. It stores two batteries and charges them via USB-C, so you wont lose any more caps.

Solid advice 👍
