Oh man, the 5D IV is a total beast! Landscape work is all about stability and light control. Honestly, an L-bracket like the Really Right Stuff L-Bracket for Canon 5D Mark IV is a game changer cuz it keeps ur weight centered on the tripod. I'm sooo satisfied with the Lee Filters 100mm System Foundation Kit square system too—it makes stacking stuff easy. Dont bother with a remote for hiking! gl!

Respectfully, I'd consider another approach. I mean, I'm still kinda new to this compared to some pros, but I've found you dont always need the most expensive stuff to get the job done! Since youre hiking, I'd focus on keeping things light and budget-friendly. * L-Bracket: I've been super happy with the 3 Legged Thing QR11-L Universal L-Bracket. It's way more affordable than the custom RRS ones but still feels really sturdy on my 5D IV.
* Filters: Square systems seem like a lot of faff for hiking. Maybe try the K&F Concept Nano-X Magnetic Filter Kit instead? It's super light and the magnets make it basically instant to use in the field. Also, I just use the built-in intervalometer! It's one less thing to lose in the dirt and works great for long exposures. Save your money for more gas to get to the trails lol. gl!

Yo! Jumping in here... Honestly, I've had a different experience than the first reply. Don't get me wrong, RRS is top-tier, but for a more practical setup, I'd actually suggest a different approach... well actually, it's about balancing that portability you mentioned. • L-Brackets: Sunwayfoto PCL-5DIV Custom L-Bracket vs the RRS. In my experience, the Sunwayfoto is basically just as rigid but way more cost-effective. It fits the 5D IV perfectly and still lets you access the side ports without a struggle. Its a solid win for long-term value. • Filters: Breakthrough Photography X4 CPL 77mm vs. a square system. Since youre hiking, square systems like the Lee Foundation Kit can be a bit of a hassle... I mean, they're bulky and catch the wind like crazy! The X4 screw-ons are lowkey the best move for weight. The glass is seriously sharp and you wont get that annoying color cast. • Shutter: Built-in Timer vs. Canon RS-80N3 Remote Switch. I've tried the internal intervalometer, but its kind of a pain to menu dive when youre losing light fast. A simple wired remote like the RS-80N3 is just more reliable and tactile in the field. But yeah, dont overcomplicate the kit. You've got an amazing camera, so just focus on keeping the setup light enough that youll actually want to carry it! gl 👍

I totally agree that balancing cost and portability is the sweet spot for hiking. Looking at the current market research and user trends, I think the Kirk Enterprise Solutions BL-5DIV L-Bracket is the sleeper hit for the 5D IV. It’s basically the gold standard for precision machining—often more robust than the universal options but without the RRS premium. For filters, the industry has really shifted away from some of the older names lately. Honestly, the NiSi V7 100mm Filter System Kit is the way to go; it’s a much more modern, integrated design than the Lee, and the optical glass quality is top-tier with almost zero color shift in my experience. Quick tip: the built-in intervalometer is great, but it can be a bit clunky for complex long exposures. I’d suggest grabbing a Canon RS-80N3 Remote Switch as a backup. It’s super light, doesn’t need batteries, and gives you that tactile control for bulb mode that the internal menu just can't match. It’s pretty much a non-negotiable if you’re doing serious night or water vistas where timing is everything.

Yep been there done that. Can confirm everything said above is spot on.
