And this is the reason for some of your measures differences. With its 47.3-megapixel sibling, Panasonic Lumix S1R, the Lumix S1 is Panasonic’s first foray into full-frame mirrorless photography. Seems very odd not to include downscaled 1080p analysis and to compare 6K/4K against Alexa 2k/1080p downscaled output…. So, dynamic range is the range of light values present in a scene. The Panasonic S1 has measurably better color sensitivity, and therefore technically has better color discrimination than the Canon EOS R, which is the latter sensor’s weakest area and may be noticeable in some images — for example, in areas of smooth gradations. In the Sony’s favor, there’s some increase in color sensitivity at 51,200 and above, but the results are close enough to be considered identical, with the differences unlikely to be visible in images except perhaps at the highest ISO value. LUMIX S1R świetnie nadaje się do wykonywania zdjęć w wysokiej rozdzielczości, LUMIX S1 pozwala na wykonywanie wysokiej jakości zdjęć i filmów, a LUMIX S1H został stworzony z myślą o nagrywaniu. As befitting a pro-oriented model, the new camera has two media card slots, one for XQD and a second that records to SD UHS-II media cards. And yes, I have not decided on this subject myself either…. The Panasonic Lumix S1 also performs excellently at higher sensitivities and can easily be compared with the best cameras from the competition, such as the Sony A7 III and the Nikon Z6. It was recently updated with the the availability of the DMW-SFU2 firmware, which adds the following functionality:-V-log transfer curve allowing 14+ stops of recorded dynamic range. The 13.8 SNR=1 result here is actually underestimated as log is not decompressed so it is likely that in an HDR space this camera has 14+ stops. For a full frame sensor, those values are average. The Zcam has strong temporal noise reduction as well creating the exact same artifacts lol. 2: Dynamic Range comparison of the Panasonic LUMIX S1 – it comes in just behind the URSA Mini Pro 4.6 If we compare this result to the Dynamic Range of the Panasonic GH5S in HLG mode (ISO800, NR = 0) coming in at 9.9 stops, this is about 2.3 stops higher! I am extracting I- frames from the camera file in high quality tiff. The Panasonic S1 has a native sensitivity range of ISO 100-51,200 with expansion settings pushing to ISO 50-204,800. Na starcie jest więc droższy niż bezpośredni konkurenci: Canon EOS R (10 499 zł), Nikon Z6 (9500 zł) i Sony A7 III (8700 zł). Depending on the gap between the log curve and the gamma curve of your tiff your results are skewed differently and can be predicted almost without making any measurements. The 0.1 stops could be due to the low pass filter blurring some noise on the pixel level (as mentioned earlier, see speculation #3). Seems like the only number that really matters is DR at 1080p downscaled from various sensor/recording modes since that is the only data that can be directly compared as some other cameras where only tested at 1080p and we know that testing at 1080p gives an advantage in this measurement. For your info, comparing the Panasonic S1H 4K DCI dynamic range results to the Panasonic S1 UHD results, we are getting almost equal numbers: 12.3 stops for the S1H, 12.2 stops for the S1 at SNR = 2. Or re-do the test in ProRes Raw when that’s working. How does it affect the dynamic range captured by the camera? Are you sure the temporal noise reduction you’re seeing isn’t just a side effect of aggressive compression? But even a jpg image like you mention above can show the full DR of a camera. Doesn’t matter if shot internally or externally in ProRes HQ. This is a very high value – the rolling shutter is partially mitigated thanks to the stabilized sensor so handheld shooting is no problem but takes it slow on pans. I could not see any macro blocking in the shadows so it does looks robust to my eye. Hence our method to use the files straight out of camera, be them LOG or not. More info can be found here). This comes unexpectedly, as I was assuming that the 6K sensor width would be scaled to 4K hence the noise and therefore dynamic range should slightly improve. You have a point there (coming from the Blackmagic world myself too). Thanks for your very informative tests and reviews of this camera. Read the Panasonic Lumix S1 review. Notice that we are getting almost exactly the same result as with ISO 640! Price: $3,698 Although it’s an excellent all-round performer, its key strength is its (Portrait) color depth, and its score of 25.2 bits is the second-best result (by just 0.1 bit) we’ve seen for a full-frame sensorat this resolution. Wejdź i znajdź to, czego szukasz! Also it gets worse the higher the ISO gets till ISO 3200 where noise and noise reduction are the strongest. Its key strength is its (Portrait) color depth: at 26.4 bits at base, it is the joint second-best result for a full-frame sensor. Passionate shooter who isn't doing this for a living. I’ll stick with my GH5 for now…Maybe ill get a firmware update. I’m hoping that a future S1H firmware update will allow you to turn off all sharpening and noise reduction, which might result in a more “organic” image. More than 12 stops can be identified at ISO4000 (even the 13th stop looks still quite solid to my eye). Thanks for this Gunther. Thanks! Gunther, I would love to see side-by-side comparison shots where you can visibly demonstrate the “it feels thin, lacks depth in a way” comments about the S1H against a camera that does not show these issues. More than 12 stops can be identified above the noise floor. Waveform plot of the Xyla 21 step chart Panasonic S1H at 4K DCI Full frame V-Loog ISO640 showing 12 stops above the noise floor. No spam, guaranteed! You seem also to suggest elsewhere that shooting 4K and then using results at HD in an editor brings benefit compared to shooting HD in camera again this is incorrect. Read more about our Comment Policy. This now is a good result – but again the Panasonic S1 was better at 10.4 [ms] at 25 fps. Now let’s see what happens if we increase the ISO to the second gain value, namely 4000. Panasonic has built the camera with a sealed magnesium alloy body, a durable shutter that’s capable of 400K shutter actuations, and a high 1/320 sec flash synchronization. DYNAMIC RANGE AND NOISE. Hi Rolf.Sorry, nothing new we can share here.Hope to get the chance and test the S1H at some point. IMATEST dynamic range result Panasonic S1H in 5952×3968 (full frame 3:2 mode) V-Log ISO4000. It is a pleasure to use the Lumix S1. Panasonic is aiming the Lumix S1 at creatives who want to be able to shoot both stills and video. In any case I agree that there is something strange going on with the image – see my comment above – it feels thin, lacks depth in a way and is far too clean. You need to use the Vlog to v709 LUT this is the only LUT that has no looks. Typical of stabilized sensors, the S1 also has a multi-shot high-resolution capability that allows the creation of 96MP images. Click here to open our interactive DxOMark image sensor ranking tool. In this video, I’ll show you a quick comparison of Panasonic Lumix S1 10 bit V-Log output vs normal standard profile vs GH5S 10 bit V-Log L vs Sony A7III 8 bit S-Log2. So yes, I am not getting your point unfortunately …, You are creating a tiff of a zip file because log is a way of compressing data. Quite interestingly the dynamic range drops to 12.3 stops. It actually is a very unfamiliar experience. ... Best EVF, best IBIS, dual card slot, great dynamic range and high ISO performance, fully touch screen, 400,000 shutter life, great ergonomic and work with my Canon lens. As the table below shows, the 24MP Panasonic S1 sensor performance is ahead of its rival from Canon, the 30.3MP Canon EOS R, with the Panasonic delivering better results in all test areas. Photons to Photo has just published the dynamic range result of Panasonic Lumix S1R full frame mirrorless. How does it affect the dynamic range captured by the camera? Even more surprising is the fact, that there is almost no difference between ISO640 and ISO4000 in 4K DCI mode – only 0.1 stops of dynamic range are lost switching to the higher ISO value – very impressive! You are already in safe range and all the LUTs are also in safe range so I do not see an issue. Imagine what that would do to the cat video business? As described by my colleagues Nino, Jeff, and Johnnie in detail here, the Panasonic S1H is designed with a “video first” mindset by Panasonic and ticks a lot of my personal boxes. Crushing shadows? I believe you guys make a lot of efforts to do those tests but I have sometimes the impression that among you there is a lot of passion but not much engineering knowledge.On this an other posts on this website you allude that when you take footage at higher resolution or lower resolution on the same readout SNR should improve. Combined with the Lumix S1’s incredible dynamic range, color tonality (the skin tones are magnificent), and outstanding high ISO performance, this combo has worked amazingly well for the 3 weddings I’ve shot with it so far. For a more detailed examination of sensor performance, we’ll compare the Panasonic Lumix DC-S1 to two of its closest mirrorless competitors, the Sony A7 III and the Canon EOS R. Throughout the ISO range, the Panasonic S1’s color sensitivity more or less matches that of the Sony A7 III. Now we are left to speculate what is happening here – why are we getting 0.4 stops less? Should I use the nicest rec709? You see the point. Filmmaker and LUMIX Ambassador Nick Driftwood guides you through the settings for shooting in Hybrid Log Gamma (HLG) on the LUMIX S1H in order to record the wide dynamic range for displaying footage on HDR-Displays. Applying a LUT? I also think that we probably have to get used to ultra high res, super clean video first before we make judgements. You should consider performing tests using an HDR colour space after a transformation LUT unless you use RAW as SNR is impacted by log compression in the darks. For 5.9K 16:9 mode at 23.98fps, a rolling shutter of 24.8 [ms] is measured, for 29.98fps the result is better at 21 [ms]. For its first foray into full-frame cameras, Panasonic has selected a CMOS sensor with the same 24MP resolution as that used by both the Sony A7 III and the Nikon Z 6. The Panasonic S1’s 24MP full-frame CMOS sensor achieves a high overall DxOMark score of 95, which is the 12th-highest place overall among all of the cameras in our database. In this review, we have compared the Panasonic Lumix DC-S1 to its most relevant rivals from other brands. At the rear, the S1 has a 3.2-inch touchscreen monitor that can both tilt and flip. Thank you for your prompt reply I was not actually expecting it!Currently you have defined an value of SNR 2 on source files across the board irrespective of format used as a measure of usability however nobody will produce files in V-Gamut V-LOG they will be rec709 and as you point out what matters is usability which is subjective not objective anyway.So I would first apply a normalisation to Rec709 and then take measures using your ffmpeg method in 8 bits and do some SNR computationsClearly this workflow will deteriorate SNR because of the need for additional conversion however it will better reflect real life usage in my opinion as currently you are not comparing apples with apples and it does not make sense to come up with absolute figures.
