소니 CFexpress 4.0 Type A TOUGH 메모리 카드

It handles 4K video without any stutter or lag, which is exactly what I needed for my shoots. The 512GB capacity gives me plenty of room to work without constantly offloading files.

The file transfer speeds are genuinely impressive — I moved a full burst of RAW shots in under a minute, and the tough build gives me zero worry when swapping cards in the field. It's pricier than I'd like, but for demanding shoots it's worth every cent.

Pulled the card out of my camera after shooting a long wedding—no heat issues, no lag, even with bursts of raw files. It's rugged and fast, exactly what I needed.
