idk, i've hauled my 5d mark iv through the dolomites and iceland, so i totally get the struggle. it's a beast but the weight is real. here's how i'd handle the gear logistics: - **power:** skip the Canon Battery Grip BG-E20. it adds way too much bulk for train hopping. carry 3 or 4 Canon LP-E6NH Lithium-Ion Battery (2130mAh) packs instead. keep 'em in an internal pocket so the icelandic cold doesnt drain the voltage prematurely.
- **straps:** the Peak Design Slide Camera Strap (Black SL-BK-3) is good, but the Peak Design Capture Camera Clip (Black CC-BK-3) is basically mandatory for hiking. it puts the weight on ur pack's shoulder strap rather than ur neck. - **tripods:** compare the Peak Design Travel Tripod (Carbon Fiber) vs the Gitzo Traveler Series 1 Carbon Fiber Tripod (GT1545T). peak is more compact, but the gitzo has better torsional rigidity for that heavy 24-70 glass. honestly, go with the gitzo for stability in high winds. gl!! 👍

^ This. Also, skip the brand name battery prices if you want to save some cash for the actual trip. Ive spent way too much on gear over the years and honestly, third-party stuff has come a long way in terms of reliability. Since youre doing the Alps and Iceland, you definitely want to keep that 5D IV safe without spending another thousand dollars. A few things Ive found that really work:

• Power: Instead of the pricey Canon originals, look at the Wasabi Power Battery 2-Pack for LP-E6NH. They are a total steal and I havent had one fail on me yet. Just keep em warm in your pocket like the other guys said.
• Straps: If the Peak Design stuff feels too expensive for what it is, the Altura Photo Rapid Fire Camera Neck Strap is a solid budget alternative. It carries the weight on your shoulder instead of your neck, which is a lifesaver on long hikes.
• Tripod: If you want something cheaper than Sirui but still stable for that heavy 24-70mm lens, the Vanguard VEO 3GO 235AB Aluminum Travel Tripod is a great middle-ground option. Its light but feels planted.
• Storage: One thing I wont go cheap on is memory. Grab a SanDisk 128GB Extreme PRO CompactFlash because reliability is everything when youre shooting once-in-a-lifetime stuff. Dont risk the cheap unbranded cards for your dream trip...

Can confirm

Agreeing with SilverFox on the battery grip stuff. It makes the 5D Mark IV way too bulky for hiking and train hopping. Keep it lean. If you want to save some cash on the tripod without sacrificing stability for that 24-70mm setup, you dont need to drop Gitzo money.

• Sirui T-1205 Carbon Fiber Travel Tripod is a solid budget alternative. Its light but doesnt feel flimsy when the wind picks up, which it definitely will in Iceland.
• Grab a Think Tank Photo Emergency Rain Cover Medium. The 5D IV is weather sealed, but salt spray and mountain rain can still gunk up your dials over two weeks. Better safe than sorry.
• Instead of buying four official batteries at full price, maybe get a Nitecore UCN1 Dual Slot USB Travel Charger. It lets you charge your spares from a power bank while you are on the train, which is a lifesaver when you are away from an outlet. tbh, neck straps are a trap with heavy DSLRs. Even the fancy ones. Look at a sling like the BlackRapid Sport Breathe Camera Strap if you want the weight off your spine. It distributes the load across your shoulder much better for long days on your feet.
