Honestly, be careful with that 'no ND' logic. My trip to the Swiss Alps last summer was a wake-up call because the glare off the peaks was so blinding it washed out everything. Since the drone has a fixed aperture, it cranks the shutter speed way up. This makes your footage look jittery and weirdly sharp, losing that smooth motion. I would suggest looking at the K&F Concept ND Filter Kit for DJI Mini 4 Pro since they're usually way cheaper than the big names. For storage, you might want to consider the Samsung PRO Plus 256GB microSDXC V30. It handles the 4K 60fps bitrate perfectly and saves you a few bucks for some Swiss chocolate, tbh. TL;DR: Get a budget ND set and a solid V30 card. Without NDs, the mountain sun will make your video look like a cheap soap opera tho.

I have been using the Lexar Professional 1066x 256GB microSDXC and it works well without any glitches. Honestly, the real MVP for Switzerland is a StartRC RC 2 Lanyard Neck Strap. I was so happy I had one when hiking near Zermatt cuz it kept my hands free to check my map without constantly putting the controller down. Definitely worth the small cost... really saved me.

Unfortunately, the drones sensor isnt as good as expected in high-contrast alpine settings. I had issues with highlights that ruined my footage. For a tight budget, these are the only essentials worth getting:

• SanDisk Extreme Pro 256GB microSDXC V30
• Freewell All Day ND Filter Set for DJI Mini 4 Pro I definitely suggest prioritizing the card. I had issues with slower ones failing during high-bitrate recording.
