Yes, the Nikon Z8 works with the SanDisk Extreme microSDXC UHS-I 128GB — but only requires the bundled microSD-to-SD adapter (included with the card); clears.
Nikon Z8 has a full-size SD card slot. SanDisk Extreme microSDXC UHS-I 128GB (real write speed 130 MB/s) fits via the bundled microSD-to-SD adapter and clears this camera's standard/base recording modes (UHS Speed Class 3), but does not reach the ~250 MB/s sustained write speed this camera's manual recommends for its high frame-size/rate video modes -- those modes are CFexpress-recommended anyway.
Conditions for compatibility
requires the bundled microSD-to-SD adapter (included with the card); clears standard/base recording modes only, not this camera's high-frame-size/rate modes (~250 MB/s recommended, CFexpress territory).
“Nikon Z8's own manual states its SD/microSD card-slot speed-class requirements; this card's write speed of 130 MB/s is compared against that published floor.”
