Yes, the Panasonic Lumix G9 II is compatible with the SanDisk Extreme microSDXC UHS-I 128GB.
SanDisk Extreme microSDXC UHS-I 128GB is V30 class. Clears: MP4 4K30 LongGOP (72 Mbps, requires V10); MOV 4K/C4K LongGOP (200 Mbps, requires V30). Does not meet the floor for: MOV 4K/C4K ALL-Intra (400 Mbps, requires V60); MOV 4K/C4K ALL-Intra (top tier) (600 Mbps, requires V90).
Limitation
Does not meet this camera's V60/V90 floors for ALL-Intra 4K recording -- MOV 4K/C4K ALL-Intra requires V60 (400 Mbps), ALL-Intra top tier requires V90 (600 Mbps); this card is V30 class. The bundled microSD adapter provides physical fit only; it does not change the card's class rating. Clears MP4 4K30 LongGOP (72 Mbps, V10) and MOV 4K/C4K LongGOP (200 Mbps, V30) but not either ALL-Intra tier.
