The S1 and S1H were technically different from each other, and at the time of announcement, the Panasonic S1H was better in video core specification
In this table, we have shown you the major difference between the Panasonic S1 and S1H cameras
And the NEXT update is about the Panasonic S1 II with Z6 III 24 MP Partially stacked CMOS sensor
Panasonic has started distributing firmware update Ver.1.4 for the ” LUMIX S9 “. It appears to fix some bugs and be a minor update.
Fixed a problem where some settings would revert to the default settings after updating the firmware to Ver.1.3.
Fixed a bug in recording gain settings.
Fixed an issue where the password authentication prompt would not appear when connecting to Wi-Fi.
Improved operational stability.
Panasonic S9 is selected as the best content creator camera by TIPA., The camera, after the V1.1 update, has become one of the best cameras for professionals.
The LUMIX DC-S1R Mark II is a mirrorless camera from the LUMIX S series, announced at the end of February 2025. It is equipped with a newly developed 44MP BSI sensor and a processor that supports high-speed processing using L2 technology. It supports 40 frames per second continuous shooting and 8K 30p video recording. As an alternative to expensive stacked CMOS sensors, it has high-speed performance.
At the same time, it is significantly smaller and lighter than the previous model, and the selling price, at least in North America, is cheaper. Furthermore, it has a high-resolution EVF and a tilt + vari-angle monitor, but the body size is close to that of the S5II.
Key points of Panasonic S1R II Test Results
According to the Photons to Photos test results, NOISE REDUCTION is applied to RAW from ISO 6400 onwards, which results in higher test scores, but caution is advised if you value detail over noise. The results are very similar to DPReview’s studio scene test.
On the other hand, unlike the previous model, which applied noise reduction even at base ISO, it seems that the noise reduction process is not applied at low ISOs. If you are shooting stars, etc., it seems that there will be no problem if you keep the ISO up to around 5000.
While the peak values are lower than other high-resolution sensors, the difference in performance is not surprising, and in comparison, the results are better from ISO 6400 onwards (thanks to noise reduction).

One of the best budget cameras to record 6K open-gate recording, earlier or when it was announced, there was a 4K 15-minute recording limit in the camera, and for which it was criticized at the time of announcement. But Panasonic listened to us, and on October 9, 2024, they released their first firmware update, version 1.1, and they removed the recording limit. Now, it does not have any recording limit in 4K 30fps mode or even in open-gate recording as long as your memory card isn’t full or the camera doesn’t face any kind of overheating issues.
But again, practically, the overheating performance of this camera is very good, and users are quite happy with the usage of this camera. Just keep in mind the camera is using the first generation of hybrid autofocus similar to what was used with the Panasonic S5, S5II, and S5IIX, so autofocus tracking is not on par with Canon and Sony cameras.
In the latest firmware update, version 1.3, they have again tried to optimize the overall operational speed of the camera. Additionally, they fixed a problem where when connecting to a Wi-Fi network, the password was always required. Now, it has become a one-time entry, so overall connectivity performance has been improved along with the operational speed of the camera.
– When directly connecting the camera and smartphone via Wi-Fi, the connection has been changed to always require password authentication. (The [Wi-Fi Password] menu has been removed.)
– The [TKIP] encryption method is no longer supported when connecting to Wi-Fi via an access point.
– The [No Encryption] option in network authentication is no longer supported when connecting to Wi-Fi via an access point.
– The image transfer feature to PC via Wi-Fi has been removed. (Only European/Ukrainian models)
Other improvements
– The startup speed when powering on has been improved.
According to the latest rumors, Panasonic is gearing up for a major product camera announcement in April 2025. The information comes from a reliable SAR YT channel. It is expected to be a direct competitor of the Sony FX3 camera, featuring the same compact body style without an electronic viewfinder. The news is not limited to this camera—based on past registrations done by Panasonic, three more cameras are expected to arrive from Panasonic in the next few months.
Confirmed Information: What We Know So Far
Panasonic’s next camera is coming in April 2025.
The upcoming camera is a full-frame L-mount camera designed specifically for videographers and professional cinematographers.
It will not include an electronic viewfinder. The design is plain and simple, similar to the Sony FX3 camera, but Panasonic also has a box-style cinema camera. I doubt whether they are preparing for their next box-style camera announcement.
Let’s Talk About Some Unconfirmed Information
The sensor is the same as the one seen in the Nikon Z6 Mark III camera—a partially stacked 24-megapixel CMOS sensor.
The source also mentioned that instead of a 26MP partially stacked sensor, it can also use a Sony-manufactured full-frame type CMOS sensor of 24MP resolution, providing faster readout speed to minimize rolling shutter issues.
The sensor details are unconfirmed at this moment; however, we will update this portion as soon as we get the latest information related to the same.
It has been very clearly mentioned that the upcoming camera is not a Panasonic S1H Mark II camera. Yes, it is coming, and it is expected to arrive later this year, but the April announcement is not the S1H.
It has been explicitly mentioned that three new Panasonic cameras are coming, and they are expected to arrive soon. Some of them may even appear before summer. Just like the next camera announcement in April, based on industry insights, between April and July 2025, we will have one more fixed-lens compact camera from Panasonic. Although the exact name remains unclear, it may be a true successor to the Panasonic LX100 Mark II camera.
Now, due to a huge surge in demand, the Panasonic S1R Mark II camera, which has been announced recently, is facing shipping delays. However, even in this situation, Panasonic is ready to announce new products one after another without any delay.

This article, “Panasonic’s Major Camera Announcement in April 2025,” was first published onTheNewCamera.com.
If you’re into professional content creation or cinematography, then you have to take care of the Rolling shutter in your camera. Let’s talk about Panasonic’s Lumix S1R II, a camera packed with versatile modes and high-resolution potential. However, since the camera uses the 44.3MP Full-Frame CMOS Sensor, it’s a traditional sensor with a 25ms readout speed.
The question isn’t just “How bad is it?” but “How can you make it work for you?” In a recent hands-on test done by Tech Through the Lens channel and Gerlad Undone, they did a really extensive and very useful test, let’s find out the important details of the test
Beyond the Numbers: What Does Rolling Shutter Really Mean?
STacked vs Non-Stacked vs Global Shutter Sensor – We all know when we are working with stacked CMOS sensors we do not have to worry that much, that’s the reason why professional camera makers like RED mostly use Global shutter sensors. But, ARRI ALEXA cameras, including models like the ALEXA 35 and ALEXA Mini LF, primarily use rolling shutter technology, not global shutter. While ARRI is known for its high-quality image sensors, they currently lack a cinema camera with a global shutter, but thats a comletely different set of topic.
Average Sensor Readout Speed Table
Sensor Type
Typical Readout Speed Range
Notes & Examples
BSI CMOS
15–40 ms (1/50–1/25 sec)
Common in mid-tier cameras. Faster than traditional CMOS but slower than stacked designs. Sony A7 IV has a sensor readout speed of 26.8 milliseconds
Stacked CMOS
5–15 ms (1/200–1/66 sec)
Significantly faster due to integrated memory and processing. Example: Sony A1 (~4.8 ms at 50MP). Z9’s readout is 4ms.
Global Shutter CMOS
<1–5 ms (1/1000–1/200 sec)
Captures all pixels simultaneously, eliminating rolling shutter. Example: RED raptor, komodo, Sony A9 III (~1 ms or less, estimated), industrial sensors like Sony Pregius (~2–3 ms).
Lumix S1R II Sensor Readout speed
The Lumix S1R II’s wide range of shooting modes enables variable writing speed in the camera, the best part is now we have detailed information of the readout speed of each mode summarized in the table below
Panasonic S1R II Sensor Readout Speed Table
Mode/Resolution
Estimated Readout Speed
Notes
Open Gate (6.4K, DRE On)
~23 ms (1/43 sec)
“sloppy” at 23 ms, typical for high-res BSI CMOS mode.
4K 48p
~15 ms (1/66 sec)
significant jump to 15 ms with an 11% crop, faster readout mode. Since the readout pattern changed due to crop
4K 24p
~23–25 ms (1/43–1/40 sec)
Estimated based on slower baseline BSI CMOS performance (similar to Open Gate without crop trick).
4K 120p
~10–12 ms (1/100–1/83 sec)
Estimated as the fastest rolling shutter mode, but subsampled with trade-offs in quality.
8K 30p
~25–30 ms (1/40–1/33 sec)
Estimated for full-sensor 8K; slower due to higher data load, aligned with BSI CMOS limits.
Open Gate (8.1K, Future)
~25–30 ms (1/40–1/33 sec)
Projected based on 8K performance; firmware update expected to maintain similar readout.
Stills (44.3MP, Electronic)
~20–25 ms (1/50–1/40 sec)
(~1/50 sec) and typical BSI CMOS behavior for high-res stills.
The S1R II’s rolling shutter varies wildly depending on how you configure it, with this table we wanted to give shooters a practical sense of what’s usable—and what’s not.
The 48p Hack: Speed Without Sacrifice
That’s the best part of the test, during the test while Shooting in 4K or 5.9K at 48p (with the intention of dropping it onto a 24p timeline) unlocks a hidden gem. Yes, The camera does an 11% Crop in 16:9 recoding mode due to the crop, when the sensor readout area becomes less and maybe the camera is using slightly different readout pattern, a read speed that goes from 23ms to mind whopping 15ms. And there is no compromise with the AF system of the S1R Mark II camera in 4k 48p mode.
The camera is still able to deliver 11.9 stops of dynamic range in 4k 48p mode, don’t forget to keep on the Dynamic Range Expansion (DRE) while recording.
Use a 360-degree shutter, cut half the frames in editing, and you get a fast mode that avoids rolling shutter problems without ruining the picture. For filmmakers who care more about smooth motion than a full frame, this trick could be a big win.
Panasonic S1R II – 8k & 4k 120fps mode
The Panasonic S1R Mark II camera records 8K video recording internally at up to 30fps in 10-bit H.265 with 14 stops of dynamic range, well I think Camera processing power touches its limit while shooting 8K and that’s why subject detection of the camera gets disabled, A firmware update (expected later in 2025) that will address several issues regarding performance update. BTW, in almost the same price range we have Nikon Z8, was released back in May 2023, can record 8K 60fps internally with full-time AI AF in 12-bit N-RAW at a data rate of 722.5 MB/s.
Meanwhile, 4K 120p mode of the Camera doesn’t show any rolling shutter issues while recording high-speed videos due to its linked skipping readout mode that enables faster readout at a Higher Frame rate, but exposure isn’t proper, a significant amount of 1.5x crop, and since the processor is soaked up in processing 4k 120fps video the AF performance degrade. We are very sure in the upcoming Nov 2025 update Panasonic will fix most of the issues.
The Verdict: A Camera of Choices
The Panasonic S1R Mark II detailed test showed us how we can use this camera to its maximum potential, and during the entire test, the Camera never shut down due to overheating issues. but if you are confused between the Nikon Z8 OR Panasonic S1R II, we have done a short comparison that will help u decide which camera u should get between the two. So, overall the camera is made for professionals, kudos to Panasonic for putting their best innovation in the S line of Full-frame cameras.
Panasonic Camera Registrations in 2025 – Upcoming Camera Model codes of Panasonic full-frame and Micro four third format cameras, take a look below at the key points of the article
Key points of the article
From the beginning of the year, Panasonic has registered approximately four cameras in the wireless application agency P2307, P2303A, P2305A, and P2306A
After doing a little bit of research, we have found that the Panasonic P2303A could be the upcoming Panasonic S1H Mark II camera. The registered model codes Panasonic P2305A and P2306A are less certain in terms of being a full-frame camera, so it can be any of the models, including the Lumix LX100 Mark III or a G series model.
Panasonic P2303A – The Panasonic S1 H II
Panasonic registered the P2303AA camera in DEC 2024. It is believed that the 2303A is the S1H Mark II camera, the camera is dedicated to SPEED and not Resolution, just like we have the A7 series in Sony, and we have already seen the high-resolution sensor update from Panasonic the S1R II recently, now it is time for the S1 H Mark II.
Panasonic Confirms they are working on S1H Mark II
Now, in a recent post, we have published an acknowledgment from the Panasonic developer team that they are working on the S1H Mark II camera. After the announcement of the Panasonic S1R Mark II, the next full-frame camera to be announced is the S1H Mark II.
Panasonic P2306A and P2305A – LX100 III and more…
We are confirmed by the nature of product registration that both of the model codes are mentioned. the P2306A and the P2305A are MFT sensor-based updates, potentially one of them is the LX100 Mark II successor, the LX100 III camera expected to feature 25.2MP Live HYBRID MOS Micro Four Thirds Sensor from the G9 Mark II & GH7 camera. The other model could be a major update to the Panasonic entry-level line, the G100 II, so we have a huge range of possibilities let’s cross our fingers and wait for good news.
Here is a table summarizing the Panasonic camera model codes based on the provided information:
Model Code

Conclusion
So, if we sum up all the information, then the Panasonic P2307 is the S1R Mark II camera, which has already been announced and features a 44.3-megapixel full-frame sensor. Now, the next camera on the list is the P2303A, which is expected to be the Panasonic S1H Mark II camera with a 24-megapixel sensor. These two models are almost confirmed. Apart from these two, we do have confirmation from Panasonic itself that they are working on a fixed-lens MFT model camera.
