Is the Sony FX5 So Good It Just Killed the FX3 II and A7S IV for Hybrid Filmmakers?

I’ve been in this industry for over 15 years, starting on a print shop floor where specs had to translate to reality, or you’d waste a lot of money on paper. That mindset never leaves you. So when I see a new camera announcement like the Sony FX5, I immediately skip the marketing hype and look for the tradeoffs. And with the FX5, the tradeoff is crystal clear.
The Short Answer: For dedicated filmmakers, the Sony FX5’s internal 16-bit X-OCN RAW recording and VENICE-inspired workflow make the rumored FX3 II a much harder sell. But for true hybrid shooters—those who rely on world-class stills and video—the FX5 is a non-starter. Its lack of a photo mode ensures the rumored A7S IV remains not just relevant, but essential.
So, What is the Sony FX5, Really?
Let’s get this straight. Sony insists the FX5 is not an FX3 II. It’s a purpose-built, compact cinema camera designed to bring features from their flagship VENICE line into a smaller body. It’s built around a new 16.6-megapixel sensor, which sounds low, but is optimized for one thing: incredible video. We’re talking 5K Open Gate recording, 4K up to 120 fps (with 240 fps coming in a firmware update), and—this is the big one—internal 16-bit X-OCN RAW.
For anyone who lives and breathes in DaVinci Resolve, that last spec is everything. Internal RAW in a body this small is a massive workflow advantage. Add in a triple base ISO of 800, 4000, and 12800, and you have a low-light monster designed for serious color grading. It’s a production tool, through and through, right down to the Venice-style menu system.
But look at what’s missing. No photo mode. At all. No internal ND filters. This isn’t a camera for someone who needs to grab a high-quality still for a client between takes. This is a camera that expects to live on a rig, surrounded by accessories, serving a singular purpose.
The FX5 vs. the Ghost: Does the FX3 II Even Make Sense Now?
This is where things get interesting. The FX3 was the ultimate run-and-gun hybrid video machine. It had the heart of an A7S III in a body made for video shooters. The rumors for the FX3 II pointed to an evolution of that idea: maybe 6K or 8K, better autofocus, and extreme 4K 240fps.
But the FX5 just leapfrogged it on the most critical feature for pure cinema quality: internal RAW. Why would a dedicated video shooter choose an FX3 II, which will almost certainly record a compressed codec like XAVC, when the FX5 offers the full-fat 16-bit RAW file internally for a similar price point?
The only way an FX3 II makes sense now is if it leans hard into the hybrid space, keeping a photo mode and perhaps offering a higher-resolution sensor than the FX5. But then it starts to step on the toes of the A7S series. Sony has essentially forced a choice. If video is 99% of your job, the FX5 is the obvious answer. It feels like Sony just took the wind out of its own sails for the FX3 II, unless it’s positioned as a much cheaper, more accessible B-cam.
The A7S IV Is Not Dead. It’s More Important Than Ever.
While the internet speculates on the death of the FX3 II, the role of the A7S IV has never been clearer. The FX5’s biggest omission—the lack of a photo mode—is the A7S IV’s entire reason for being.
I shoot with my Nikon Z6 III. It’s a hybrid beast. On a single job, I might be shooting moody studio portraits with my Godox AD400Pro and then need to pivot to capturing 4K video. That’s the life of a hybrid creator. We don’t have the luxury of bringing a dedicated stills body and a dedicated cinema body to every single shoot. We need one tool that excels at both.
That’s the A7S promise. The rumored A7S IV specs—a 24MP stacked sensor, 6K video, 8-stop IBIS—point to the ultimate hybrid camera. It’s for the wedding photographer who needs to deliver a stunning gallery of images and a cinematic highlight film. It’s for the documentary filmmaker who needs to capture broadcast-quality interviews and compelling stills for posters and press kits. It’s for people like me.
The Sony FX5 doesn’t kill the A7S IV. It liberates it. It allows the A7S line to stop trying to be a pseudo-cinema camera and instead focus on being the absolute best photo/video hybrid on the market. Sony has drawn a line in the sand: the FX line is for filmmakers, and the A7S line is for hybrid artists. And I think that’s a smart move.

My Verdict
- The FX5 is for specialists. This is not a hybrid camera, and it doesn’t pretend to be. The lack of a photo mode is a declaration of intent. It’s a compact, B-camera to a VENICE, or an A-camera for a serious indie filmmaker who values data over convenience.
- The FX3 II is now in a very weird spot. For dedicated video shooters, the FX5’s internal RAW is a much bigger deal than any rumored frame rate bump in the FX3 II. Unless the FX3 II comes in at a dramatically lower price, it’s hard to see who picks it over the FX5 for pure video work.
- The A7S IV is safe. The true hybrid shooter who needs professional stills and video in one body still has a clear path. The FX5 confirms that if you need to do both jobs well, the A7S line is still the one to wait for. Sony didn’t kill it; they clarified its purpose.
