I just received my FS7 and am looking for recommendations on matching it with my A7sii. I have a project In a couple of days and am too swamped to run tests. I'm wondering if anyone has had good luck in matching them. Slog is not appropriate for this project so I'm looking for matching them within the other general picture profiles.

I don't necessarily think this will help you, but I spotted this today and thought it was interesting re the differences between FS5 and A7sii: https://vimeo.com/groups/fs5/videos/173966063

You could try contacting the author to see if he's already worked out matching techniques/grading.

I've had good luck shooting both in Slog3 and then using the same lut with some minor tweaking. Just make sure your wb is the same. I have had success too with pp5. In that case I would suggest shooting the fs5 in 1080 10 bit and the a7sii in 4k, the more data the easier to grade.
