Sony FX3 vs. FX3A: What’s the Difference and Which One Should You Buy?
TL;DR - If you’re wondering if you should upgrade your FX3 to the FX3a - the answer is absolutely not. If you REALLY want your LCD screen resolution to be a tiny bit better then get the FX3A. Otherwise hold onto your FX3. One thing’s for sure… we won’t be upgrading our already really awesome rig!
If you don’t have an FX3 and are purchasing one and choosing between the FX3 and the FX3a… I suppose I’d just get the FX3a since the higher resolution screen would be kind of nice and I don’t use the features they are getting rid of. Read below to learn more about those features before you make your decision.
Sony has quietly released an updated version: the Sony FX3A.
But what does the "A" actually mean? And is this new version worth buying or upgrading to?
Let’s break it down.
IMO - this is not a big deal for those of us who were expecting something a little more epic (like built in ND filters, higher frame rate capabilities…)
So what we’re really looking at is a trade-off: a better screen in exchange for the removal of a few lesser-known features.
Let’s talk about what those features actually do.
What Is NFC Functionality (and Do You Need It)?
NFC stands for Near Field Communication. On the FX3, this allowed you to instantly connect your camera to a compatible smartphone using just a tap. You could transfer images, control the camera remotely, or trigger wireless pairing quickly—all without diving into menus.
For stills shooters or content creators moving fast, this was a handy tool for reviewing shots on a phone or quickly pushing content to mobile. But for filmmakers and production crews who typically transfer footage via SD card or SSD and control cameras through pro monitoring gear, NFC isn’t a dealbreaker.
TL;DR: NFC is convenient, but not essential for professional video workflows. I’ve never used it for any of our work, and don’t know anyone who really does.
What Is Infrared Remote Support?
The FX3 also supported infrared remote controls - think the classic Sony remotes with an IR transmitter that let you start/stop recording, zoom (on compatible lenses), or adjust basic settings from across the room. Never heard of them? Same.
This feature is only useful in very specific setups: tabletop filming, static interview frames, or scenarios where you want to trigger the camera without touching it. But for most professionals, IR control has long been replaced by Bluetooth, USB-C tethering, or dedicated wireless control apps.
With the FX3A, Sony appears to have streamlined the build and removed the IR sensor entirely.
TL;DR: If you rely on IR remotes, stick with the original FX3. Also, who are you? Let me know why you use them!?!?!
So What Do You Get With the FX3A?
The key upgrade is the higher-resolution LCD screen:
FX3: 1.44 million-dot screen
FX3A: 2.36 million-dot screen
That means sharper detail when reviewing shots, better clarity when pulling focus manually, and an all-around more pleasant on-camera monitoring experience - especially for solo shooters or run-and-gun setups. I mean this is pretty cool! But not worth getting a new camera for this Boston based video production company.
Everything Else Stays the Same
Both cameras still offer:
12.1MP Full-Frame Exmor R CMOS Sensor
4K up to 120fps, 10-bit 4:2:2 internal
16-bit RAW output via HDMI
15+ stops of dynamic range
Dual CFexpress Type A / SD card slots
Professional audio support via XLR Handle Unit
So in terms of image quality, color science, low-light performance, and professional feature set, the FX3 and FX3A are identical.
Should You Buy the FX3 or the FX3A?
Here’s the honest answer:
Already own the FX3? Stick with it. You’re not missing out on anything that affects your actual footage.
Buying for the first time? Go with the FX3A unless you specifically need NFC pairing or use IR remote triggers in your workflow.
Sony likely released the FX3A to simplify manufacturing and accommodate supply chain realities. This update doesn’t change the camera’s core strengths—but it does slightly refine the experience for new users.
Final Thoughts From a Boston Video Production Team
At Bunker Hill Media, we’ve used the Sony FX3 for everything from corporate interviews and brand videos to fast-paced event coverage. It’s light, powerful, Netflix-approved, and plays beautifully with our Sony lens ecosystem.
The FX3A continues that legacy, with a few small adjustments. For most filmmakers, content creators, and Boston videographers looking for a professional workhorse camera in 2025, either model will deliver. The real deciding factor? How you shoot, what gear you already own, and whether things like IR control still matter to your setup.
Need help figuring out your production kit or want to hire a team that already knows how to get the most out of this gear? Let’s talk. We’ll bring the camera—and the creative strategy to match.
-
The main difference between the Sony FX3 and FX3A is the LCD screen resolution. The FX3A features a higher-resolution 2.36 million-dot LCD (vs. 1.44 million on the FX3), offering improved clarity for on-camera monitoring. However, the FX3A removes NFC functionality and infrared remote support, which are present on the original FX3. Otherwise, both cameras share the same sensor, recording specs, and compact cinema design.
-
If you already own the FX3, there’s no major reason to upgrade to the FX3A. The two cameras are nearly identical in performance, and the minor screen resolution bump isn’t worth losing features like NFC pairing or IR remote control—especially if you use them in your workflow. However, if you're buying new, the FX3A is a solid option with a more modern display.

The Sony FX3A is just as capable for video production as the FX3. It offers full-frame 4K recording up to 120fps, 10-bit 4:2:2 color, and 15+ stops of dynamic range—making it excellent for professional filmmaking. The only improvement in the FX3A is the higher-resolution LCD screen, which may help with focus and monitoring. For Boston videographers and production teams, both models deliver top-tier performance.

The Sony FX3A and FX3 are nearly identical in terms of image quality and video capabilities. The FX3A features a higher-resolution LCD screen (2.36 million dots), but removes NFC functionality and infrared remote control support found in the FX3. Both cameras offer full-frame 4K video up to 120fps, 10-bit 4:2:2 color, and professional-grade features for video production.
