Since Sony a7C II is compact mirrorless camera, so you'd better to get compact lenses, I highly recommended the FE 16-25mm f/2.8 G, FE 20-70mm f/4 G a...
The Sony FE 90mm f/2. 8 Macro G OSS lens is a great choice.
Since DJI RS 4 and RS 4 Pro have been released, now the best choice are RS4 and RS4 Pro.
For shooting high quality 4K video, you'd better to get CFExpress Type A cards, such as Lexar CFexpress Type A Gold Series:
Maybe in late 2024 or early 2025. I think Sony will not lose this market.
Get the DJI RS 3 Mini. Or if you want more powerful gimbal, you can get DJI RS 4.
The new released Sony a9 III is the best choice.
Waiting for Sigma 24-70mm f/2.8 DG DN II Art lens.
Lenses price over $2000 are mostly weather sealed.
@beeee3 I'd love Sigma 30mm f/1.4 DC DN C lens more.
