Sigma FP2 review: the world's smallest full-frame mirrorless camera is a wonder of design

Sigma FP2: One-minute review

Sigma's FP2 is a successor to the world's smallest full-frame mirrorless camera, the FP, and it's even smaller, despite coming with a bunch of handy upgrades.

The FP2 packs a partially stacked 24.5MP full-frame sensor — one we've seen before in the Nikon ZR and Lumix S1 II. And like those cameras, it shoots 6K open gate video, only with Sigma's L-Log color profile, and RAW video through an external SSD.

It comes with 70GB built-in memory, plus a higher capacity battery — the same unit found in recent full-frame Lumix models like the S1 II and Lumix S9 — and it features a 3.15-inch tilt-touchscreen. All decent upgrades.

Autofocus performance has been improved too — the hybrid phase detection system can track more subjects, with what Sigma says is a 15% boost in speed and accuracy.

And these features are packed into a diminutive and sturdy metal body with a delightfully simple design and user experience — I love how the photo and video functions are neatly distinguished. It's an attractive package, and a camera that I thoroughly enjoyed having in my hand.

When considered purely as an upgrade to the original FP, the FP2 is a solid camera. However, Sigma's mission to make the smallest full-frame mirrorless camera comes with compromises, which means the FP2 won't be for everyone. For one, the camera doesn't have in-body image stabilization, whereas the Lumix S9, Lumix S1 II and Nikon ZR do.

There's also no built-in viewfinder, though unlike some rivals, there is an optional EVF and it's a fantastically bright and detailed 5.76m-dot unit that tilts for waist-level shooting.

When shooting photos, I regularly found myself bringing the camera up to my eye, only to remember it didn't have a viewfinder – photo and video creatives will absolutely want to pick up the optional EVF.

That for me is where the FP2 comes undone, somewhat. It's starting price is reasonable, but when you factor in the cost of accessories, the package starts to feel pricey.

There is a miniaturisation premium — Sigma isn't alone in this, however. Overall, there are better value conventional alternatives, but if size and feel matters to you, then the Sigma FP2 is well worth a look.

Sigma FP2: Price and release date

• Announced on October 23, 2026, priced from $2,199 / £1,899
• Can be purchased with various kits; with the Electronic Viewfinder EVF-21 or 50mm F2 DG | Contemporary lens
• Goes on sale from November 11

At first, the Sigma FP2 feels like excellent value — it's a beautifully designed and rugged full-frame camera with impressive specs for $2,199 / £1,899. However, that body-only price is just the beginning for a camera that works best with optional accessories — and for those the cost soon stacks up.

For example, photographers will want the divine EVF-21 5.76m-dot tilt electronic viewfinder, which which adds $500 / £500 to the cost when bought with the camera, and it costs even more when purchased separately. Or how about the camera and lens kit with 50mm F2 DG | Contemporary, which I had for the review and you can see in the pictures, which costs $2749 / £2419.

Other accessories include the Hot Shoe Unit HU-21 (same flash terminal as OM System / Lumix), base plate BPL-21, LCD viewfinder LVF-21 and battery charger BC-91. Sigma is still a decent value brand, but you just need to be aware that this camera system benefits from costly extras, and if you're upgrading that the likes of the EVF are not forwards / backwards compatible with the original Sigma FP.

Sigma FP2 specs

Sigma FP2: Design

• Even smaller than the original FP, but a fraction heavier
• Modular design with handy (albeit pricey) accessories, such as the lovely EVF
• Wonderfully simple user experience and interface

The FP2 carries the DNA of the original FP, but comes with some welcome design improvements. Crucially, it stays true to Sigma's core mission with this series — make the smallest full-frame mirrorless camera available.

It's designed as a photo and video hybrid, with a chunky switch to choose between the two and a neatly arranged menu for each discipline — the settings remain unique when you move between the two.

There's a chunky exposure dial, and a line of buttons neatly arranged under the screen, including one for color profiles (there are 13 presets, Log and RAW video options).

The 3.15-inch touchscreen is a tilt-type — impressive considering the camera is thinner than the FP, which has a fixed screen. Pulling the screen out reveals vents which presumably keep the camera cool during high-resolution video recording.

We don't get an EVF, which is no surprise given the size of the camera. However, Sigma sells the FP2 in a kit with the EVF-21 electronic viewfinder.

I actually think the modular design makes perfect sense. Shooting video and don't need a viewfinder? You have the tiniest full-frame shooter. Out taking photos and want the display? Add it on.

And I really did enjoy the display — albeit my brief experience with it. It connects to the camera's side through one of the two USB-C ports, and it's a 5.76m-dot tilt type.

Sigma has added internal memory, with 70GB of usable memory, plus there's the SD card slot. I used the internal memory a lot, and had no operational issues — I wish more cameras included internal memory like the FP2 does.

And then there's the battery — the same type as used in recent Lumix cameras, for a healthy shot-life that belies the compact size of the camera. I don't think I've seen such a large battery squeezed into such a small space before — Sigma really has worked wonders to keep the FP2 this small.

Naturally, there are compromises for the handling of such a small camera, besides the lack of viewfinder and flash. For one, it's flat-fronted, meaning there's no sculpted hand grip for a secure hold. That's no such problem with small lenses, but the FP2 is so small that even compact primes feel chunky by comparison.

It's true: when stripped back to its basic setup, there is no smaller camera in this class. But to get the most out of the camera, it needs bulking out, all adding to the cost.

What I will say is that the FP2 does modular very well indeed. Its two screw mounts for accessories are handily placed, and they can host the (supplied) loops used to secure the camera's strap, which is a neat bit of design.

The FP2's design isn't for everyone, but after almost two weeks of shooting with the camera, I really did appreciate and enjoy it, and can see how it will appeal to certain users.

Sigma FP2: Performance

• 24.5MP partially stacked full-frame sensor, no stabilization
• 6K open gate video recording up to 60fps, plus 4K slow motion up to 120fps
• 13 color profile presets and Log, but RAW video must be recorded through an external drive
• Improved autofocus performance and built-in memory

We've seen the 24.5MP partially stacked sensor before in various Panasonic Lumix and Nikon models, including the Lumix S1 II and Nikon Z6 III. In the Sigma FP2, however, the sensor is not stabilized, which makes handheld video recording much trickier.

I've included a sample reel below, which demonstrates how challenging it can be to record steady video handheld, even with a steady hand. There is a solution, mind you, and that's to record gyro data which can be used to apply stabilization to footage afterwards using specialist software. Alternatively, of course, the camera can be mounted to a gimbal.

I love the photo and video quality I was able to get from the Sigma FP2 and 50mm F2 DG Contemporary lens: 6K open gate video with a choice of 13 color presets make for quick and versatile output, in various aspect ratios for social media (4K vertical video is possible), while the Log profile is a better bet for users who want to edit after the fact.

Photos can be recorded in RAW and JPEG format, and Sigma cameras use the DNG RAW format, which is universally accepted in editing software. For high-speed action, the FP2 can shoot at a rate of up to 20fps, and for sequences up to 180 frames before the buffer slows up — a decent performance.

Sigma says that autofocus performance has been improved by 15% over the FP, with a broader range of subject detection. I found autofocus snappy on people, and it was smooth and subtle enough for video, too, but haven't had the chance to try it out extensively on other subjects, including animals.

There's 70GB of usable built-in memory, which proved reliable during my test. However, it's not possible to record the memory-hungry RAW video using built-in memory or SD card — you'll need an external SSD for that.

Sigma FP2: also consider

How I tested the Sigma FP2

• I had the camera for 1-2 weeks before its announcement, along with the 50mm F2 DG Contemporary lens
• I tried the EVF-21 electronic viewfinder
• I shot a variety of photos and videos, all handheld

Sigma introduced the camera to TechRadar a week or two ahead of its global launch, where I saw the FP2, 50mm F2 DG Contemporary lens and various accessories, including the new 5.76m-dot EVF for the FP2.

I was loaned the camera and lens only for my review, and have made the most of that time, taking the gear with me on a break to Lisbon in Portugal where I used it extensively for portraiture and travel photography.

All my images and videos were shot handheld, with no stabilization for video footage. I tried the various color profiles for video and shot in 6K and 4K.
