フォクトレンダー Prof. ハイスピード SDXC 256GB UHS-II

The write speed is incredible—I can shoot bursts of raw files on my α7 IV without any buffer lag. It handles 4K video flawlessly, and the rugged build gives me peace of mind when shooting outdoors.

I was skeptical about the waterproof claim, but after accidentally dropping this card in a puddle while swapping lenses, it dried out and worked perfectly. The write speeds during burst shooting on my α7 IV are noticeably faster than my old cards.

Dropped my camera bag on a rocky trail during a hike and the card didn't even blink—that water resistance up to a meter is reassuring too. Wrote 4K footage nonstop for over an hour and the write speed never stuttered once. Feels solid enough to survive anything I throw at it.
