The Sony FX2 is an extended version of the Sony A7 IV, optimised for its maximum cinematography specifications. So hardware-wise, both the cameras are the same — is it true? NO, we do have some sort of advancement in the hardware part, and the advancement is the introduction of the AI chip, which was absent in the Sony A7 IV, as well as the very unique tiltable electronic viewfinder design. So let’s explore the differences between the two.

What advantages do we have in the new Sony FX2 camera over the Sony A7 IV?
- It looks like a cinema camera, but it has a very deep hand grip and a very innovative tiltable electronic viewfinder.
- Additionally, we have an option in FX2 to use an XLR handle for the body part, and with that grip, we can add 32-bit audio to our videos.
- An option to record DCI 4K instead of UHD 4K in the new Sony FX2 camera with lots of custom LUTs as well as an option of extended dual native ISO range, resulting in 15 stops of DR performance.
- 30% increase in the AI autofocus performance of the new Sony FX2 camera compared to the Sony A7C Mark II or the A7 Mark IV camera.
- 16-bit RAW video recording is an option available via the HDMI port. Obviously, the Sony A7 Mark IV camera remains limited to 10-bit video.
- Introduction of active stabilisation mode as well as frame stabiliser — both of these are not in the way they should be in the Sony A7 Mark IV due to the absence of the dedicated AI chip inside the body.
- Support for anamorphic lenses and in-camera de-squeeze functionality for the recorded footage.
- Built-in internal fan to manage any sort of overheating issue if required.

Sony FX2: Built for Filmmakers
The Sony FX2 isn’t just another camera—it’s a Cinema Line powerhouse tailor-made for both aspiring cinematographers and seasoned content creators. Under the hood, it shares the same 33 MP sensor as the A7 IV, but in S-Log3 it unlocks up to 15 stops of dynamic range, giving you richer highlights and deeper shadows. Here are the standout video features you’ll love:
-
Tilting EVF: A 3.68 million-dot viewfinder that flips up 90°—perfect for shooting low or high without cramping your style.
-
Video-First Layout: Large, easy-to-find record button, full-size HDMI, plus intuitive shutter-angle control so you can dial in cinematic motion blur on the fly.
-
AI Power: Thanks to its onboard AI chip, autofocus is 30% snappier, and you get nifty tools like Auto-Framing and the Framing Stabilizer—ideal for run-and-gun solo shoots.
The one caveat? If you were hoping for full-frame 4K at 60 fps, you’ll find the FX2 capped at Super 35 crop at that frame rate—unlike its cousin, the FX3.
Sony A7 IV: The Hybrid Powerhouse
If you wear two hats—photographer by day, videographer by night—the A7 IV is your Swiss Army knife. Its 33 MP sensor churns out gorgeous JPEGs and HEIFs, and its video chops are nothing to sneeze at. Here’s why so many hybrid creators can’t put it down:
-
Stills & Motion: Capture high-res stills in Log, plus reliable autofocus that tracks fast-moving subjects with ease.
-
Flexible Design: Dual card slots and a fully articulating 1.03 million-dot touchscreen let you work confidently in any scenario.
-
Budget-Friendly: At $2,498, it undercuts the FX2 while still offering professional-level performance.
The trade-off? You don’t get the FX2’s video-optimized menus or dedicated cinema-grade controls like shutter-angle adjustment.

So these are the major differences we have between these two cameras. Yes, many minor differences also exist between the two. But without a doubt, if you are a cinematographer or a content creator who loves to have a dedicated professional cinematography camera in his or her hand, without a doubt, the new Sony FX2 is one of the best cameras.
