The A7S III is a 2020 low-light/video specialist with no confirmed successor (an A7S IV is rumored but unannounced). It has held its value unusually well because nothing has clearly replaced it.
What to do now: Reasonable to buy if you need its low-light and 4K120 strengths. If you can wait, watch for A7S IV news; also compare the cine-focused FX3.
Current price is at the best recent level we have seen, though recent prices are still drifting lower.

Adorama carries this in open-box / like-new condition from $3,149. It is not meaningfully below the new price right now, so we are not flagging it as a deal — but used pricing moves often, so check current listings if you want to compare.

⚠ Buy only if it says “Ships from & Sold by Amazon.” Third-party card listings are frequently counterfeit.
Sony Type A bodies also accept V90 SD cards (often in both slots) — a much cheaper option if you don't need CFexpress speed.
