For most people the S5K is a great option and cheaper. If you have compelling use cases that demand faster imaging and don't need the 5K/4K resolution, then the S2.5K with its 2900FPS and pSLC drive is a great option.
With Ember Firmware and App V2.2, support was added for external media and SDI output with the Ember , along with new options, including multi-camera frame sync.
With Ember Firmware and App v2.0, support was added for the Active EF Mount lens control, (with compatible SSD), and cropped (color) and binned (monochrome) modes for S5K. This was also the initial release for Ember S2.5K.
See the page for a complete history of release notes.
The latest firmware is available on the page and the App is available in the App store.
Ember has 11 stops of dynamic range, which is less than a typical 24fps cinema camera. This is an inherent tradeoff of high-speed imaging. Imagine trying to count a few hundred coins on a table: your answer would be a lot more precise after five minutes than it would be after five seconds.
Plan your shots accordingly, avoid high-contrast lighting conditions, expose for the highlights you want to keep, and use fill lighting when able to increase exposure in shadows.
ISO 100, 200, and 400 are available. These are analog gains implemented at the sensor, with minimal noise tradeoff between the three. Although Ember S2.5K has 4x the pixel charge capacity of Ember S5K, the majority of the read noise is after charge-to-voltage conversion, so there isn’t a meaningful increase in sensitivity. You will need proportionally more light for S2.5K’s higher frame rates.
These are saturation-based ISO values. Using different OETFs will still change the exposure of middle gray. For the same saturation level, HLG Beta increases the exposure of middle gray by approximately one stop compared to Rec. 709.
Ember records to an internal NVMe SSD. There are two types of internal SSD available: a 4TB TLC (standard on Ember S5K) and a 2.56TB pSLC (standard on Ember S2.5K).
By analogy to film cameras, (capture) Frame Rate is how fast the film is pulled through the camera. Project Frame Rate is how fast the film is pulled through the projector.
An active EF mount is included with Ember S5K and S2.5K.
Yes, but you will need to send your camera back to the factory if you want active control of EF lenses. If you are OK with a dumb mount (for EF lenses with manual iris) you can buy the EF mount and bolt it onto Ember with no upgrade.
Sony asked us to no longer produce our passive E-mount; we agreed.
918 grams, with the Active EF lens mount.
1/4-20 top and bottom.
M3 and easily-mountable NATO rails on all sides.
0ºC to 40ºC
The camera is IP52 and can handle light rain, but is not waterproof.
The camera mounts as an external SSD when connected to a host via USB. Recorded clips are available in the root folder of the camera drive. Even at USB 3 speeds, offloading large clips can take a long time. We recommend opening clips in-place on the camera drive and exporting trimmed sections to a local drive if your workflow allows.
Reverse polarity protection of the camera's power input is not effective when the camera is connected to a USB host. To avoid potential damage, do not plug or unplug the camera power connector while USB is connected. Always double-check the polarity of D-Tap connectors before plugging them in.
Physical slide switch for power on/off.
Illuminated record start/stop button.
High-resolution scroll wheel for menu navigation and playback scrubbing.
Select button.
1080p HDMI with on-screen display that can be hidden. An external monitor is required to operate the camera. There is no built-in LCD.
No. The front-facing ports are for future expansion but are not currently enabled.
Yes, there are several methods:
Long-range control when used on Mōvi Pro, Mōvi XL, and Mōvi Carbon through the Mōvi Controller.
Gigabit Ethernet, CAN, and PCIe interfaces are available for future expansion.
We are on a mission to build the smallest, fastest, lightest, most fun camera the world has ever seen. This brings us a bit closer to that goal.
Ultra tiny, ultra fast, ultra simple, ultra fun.
Continuous high-speed ProRes recording to non-volatile storage, limited only by storage capacity. No RAM buffer or trigger setup. It operates like a normal camera.
Really well! Tiny, global shutter, built super light and tough, and remote start/stop easily wired up to flight control of your choice with 46min record time.
4K 800fps images look dreamy, it’s like being in a Marvel film.
5K 600fps leaves some room to reframe/stabilize.
Fast and responsive UI.
Great form factor for gimbals, FPV. Cable entry on top is great for packaging.
Needs SO MUCH light.
It took us so long to get done.
Would like to have more dynamic range.
Llama, as long as the raccoon isn’t hopped up on matcha or adderall.
Apple ProRes 422 LT in all . ProRes 422 LT maintains excellent image quality with only intraframe compression (approximately 6:1 compared to uncompressed RAW) and keeps the file size and data rate reasonable for high-speed imaging. ProRes 422 and ProRes 422 HQ may be added (at lower frame rates) in a future update.
Rec. 709 and HLG Beta tone curves are available. See for more details. There is no LOG profile for Ember because LOG recording typically requires at least 13 stops of dynamic range. Ember's 11 stops of dynamic range forced onto a LOG curve would either clip highlights at very low values or amplify shadow noise unacceptably. Rec. 709 and HLG Beta are a better fit for this sensor.
! We are using the GSPRINT4521 sensor (Normal version for S5K and Quad Bayer version for S2.5K) and it has been awesome. Gpixel also has been awesome to work with.
Yes, untreated sample footage is available (S5K) and (S2.5K).
With the , any Ember can also record to hot-swappable external media in the form of U.2 NVMe SSDs. Three sizes are available: 4TB TLC, 2.56TB pSLC, and 1.28TB pSLC. These SSDs also include a built-in 40Gbps USB4 / Thunderbolt reader for faster offload.
pSLC stands for pseudo Single Level Cell and is a type of flash storage that increases the endurance 10x or more compared to Tri-Level Cell (TLC) flash, at the expense capacity...learn more if you want to nerd out. The increased endurance allows Ember to support arbitrary-length circular buffer into flash.
Yes! The 2.56TB pSLC SSD is available for purchase (Freefly P/N ) and can be installed easily in any Ember running FW v2.0 or later.
You can trigger Ember with the App, the Record button, or wire in a custom trigger using the .
Yes, with firmware v2.2 or later. See for more details.
Capture is the recording speed of the camera. is the playback speed of the recorded clip, usually chosen to match the time base of a project for easy file import. The ratio of capture speed to playback speed is the amount of slow motion applied. For example, a 600fps capture with a 24fps Project Frame Rate gives 600/24 = 25x slow motion.
PL and PL with internal ND mounts are available from and in the Freefly store.
There are additional 3rd party mounts available from .
The Ember lens mount interface drawing is available on the page.
No, focus will still be manual, but can be controlled via the App, on-camera UI, or the .
In general, no. For example, you can't adapt an E-mount lens to an EF-mount body, because the flange focal distance of E-mount is shorter than EF-mount. If you have a manual lens that isn't covered by one of the available mounts, check if it can be adapted to RF, which has a relatively short flange focal distance of 20mm. If so, consider using the .

12-26V, and up to 55W for maximum frame rate in 5K. Look for battery and power connector options. The camera cannot be powered through the USB-C port. For continuous power, we currently recommend the FXLION battery, which can be charged via USB-C while powering the camera. A dedicated AC power adapter is also available in the store.
The can be used to control the camera and view, trim, and export clips over USB, Wi-Fi or Ethernet.
A simple start/stop trigger can be implemented using the GPIO port. See for more details.
A host can fully control the on-camera menu via UART. See for the public interface definition.
