Yes, the ProGrade Digital V60 128GB SD is compatible with the Sony A7 IV.
ProGrade V60 is UHS-II V60. Sony A7 IV spec table requires V30 minimum for XAVC HS 4K and V90 for XAVC S-I 4K. Card is V60 — exceeds V30 for HS modes but falls short of V90 for S-I intra-frame recording.
Limitation
Cannot record XAVC S-I 4K (intra-frame) -- requires Video Speed Class V90 per Sony's own spec, this card is V60. Works for XAVC HS/S 4K (V30 required, met) and all lower-bitrate modes via the SD slot.
“Sony A7 IV Help Guide card table: XAVC S-I 4K at 600Mbps requires SDXC V90 or higher; XAVC HS 4K and XAVC S 4K at 200Mbps require U3/V30 or higher — V60 card supports standard 4K formats but not intra-frame 4K.”
“V60 Video Speed Class rating, which guarantees minimum write speeds of at least 60 MB/s”
