armandino: Sure we all want the best of the best all the time, but I really do not see the big deal of compressed raw at 10fps, especially on such high resolution sensor. Artifacts due compression reduce dramatically with the sensor resolution, and if you are shooting 10fps you probably want to keep the file sizes manageable anyway. I have been shooting an extremely large number of pictures in both compressed and uncompressed raw in the past years with the A7RII, A7RIII and A9 and I can guarantee that sooting compressed is not a big deal at all.

@redhed17 : thanks - exactly my point. I think it's cherry picking in the same way that floating point performance on a CPU can be measured FP16 or FP32. Sonys approach (while not without it's advantages too) does so at the disadvantage of the hit to DR. Depending on your usecase, that's either important to you or not. Nevertheless when doing benchmark comparisons on what are ostensibly computers with lenses attached to them, one needs to keep some level of (ugly word) equivalence (shudder). Now I wonder if Panasonic, Nikon and Canon were to drop to a lossy compressed continuous format would their FPS increase to match/exceed the Sony. I.e. is the limitation the electronic readout speed or the physical shutter mechanism or both!

It's a fair point and I totally agree - 6fps would be enough in those situations if not preferable especially dealing with huge files. However give me the full IQ potential that I am paying for and give me those 6 fps in full fat 14bit files where the full dynamic range of the file and the sensor is available to me. Let me choose whether to reduce the IQ or not in continuous mode.
Whether the dynamic range is visible by the client is another matter, as you aluded to the client will likely notice first if it's a beautiful image, whether colors are on point, exposure is right etc... They won't be worrying that their photographer was able to (or not) recover an extra half stop of dyanamic range in the sky. However as a photographer I'd like to be given a choice!
Panasonic can do it. Canon and do it. Nikon can do it. Sony probably could do it with a firmware update ? For me it's a question of choice.

Example of where you may want this.... very bright wedding shot outdoors during mid day and the bride and groom coming down the aisle. This is a very real world situation that as a wedding photographer you do not always have the option of working around. Would lower dynamic range and more compression stop me from shooting burst on an a7riv , no, but I'd prefer if Sony made available the full capabilities of the sensor in a burst mode similar to Nikon, Canon, Panasonic etc... However I suspect this is done to get numbers up for spec sheets.

Tango 55: The asking price of $3,699 no longer works after Sony's announcement of the A7R IV. Panasonic will probably have a difficult time selling these cameras...

Why ?!

The Sony has more resolution and 10fps lossy compressed raw.

The Panasonic has 6fps continuous raw @14bits. 30fps 6k photo (18mp), 4k60p internal, stop motion capability, focus stacking in camera, timelapse, pixel shift in camera, vastly superior IBIS on account of having significantly more room to move the sensor, backlit button for pros working events in low light, faster and more accurate low light point to point focus, better build quality, dual card slots where one is XQD, a buffer that clears near instantly and does not lock up the camera while clearing, full touch screen interface, electronic focus limiter, higher bit rate video, in camera raw processing, etc...

looks like you get what you pay for to me, especially when one factors in ergonomics and build.

ybizzle: The Sony A7R IV announcement just made this camera irrelevant...

@MirrorlessHater : that's actually incorrect. S1R can do 4k60p with 1.09 crop (practically full frame when one factors in video recording aspect ratio ~ albeit with binning), nevertheless it still allows you to capture high quality 4k60p footage internal at FF. If you don't want binning , you can use a S35 crop (1.5 factor).

Your comment on irrelevancy to the A7riv is interesting. Even after the A7riv I feel that the A7riv is playing technological catch up on many levels. Not least being video where the APSC crop for video is now 1.6 on the A7riv and the higher bit rate for video on the S1R as well as option to shoot FF 4k60p.

Back to stills, you have the option of 6fps 14bit raw -> 6k photo @30 fps (albeit 8bit raw) on the S1R and 10fps lossy 12 bit on the Sony a7riv.

There are pros and cons to both systems. One must pick their own subjective poison. IMHO as a feature packed body with 1dx level build, touch screen, features, speed of operation, the S1/R are the ones to beat.

How were the dynamic range tests calculated? DXOMark and PhotonsToPhotos report the S1R at peak is at or marginally better to it's peers at base iso, falling behind until iso 800 and pretty much neck and neck from then on.
When you factor in that it won't suffer from banding/striping image quality artifacts one has to wonder if it actually has MORE useable dynamic range for working pros than a A7riii, A7riv, Z7 and other mirrorless bodies that can suffer from imaging artifacts because of PDAF.
On the point of FPS, why did the review hit the S1R for 'only' having 6fps when it shoots at full 14bit raw. Competitors (such as A7riv) drop the quality to 12bit to publish higher figures. A9 shoots 5fps mech, 20fps with e-shutter and 12bit compressed raw. In that same spirit one could consider the S1R's 30 fps 6k photo mode if only caring about numbers ;)
On the EVF wobble and AF tests. I noticed the date of some of the photos. You didn't get a chance to test with latest 1.2 firmware?

peeyaj: I will post the conclusion of Engadget's review as it perfectly sum up my thoughts:

"In just the last two weeks, though, things have changed drastically. Sony unveiled the A7R IV,. $200 cheaper than the S1R. At the same time, it lowered the price of the A7R III from $3,000 to $2,500, making it $1,200 cheaper than the $3,700 S1R

The latter is a cruel, killing blow. Given Sony's price drop, which seems to be permanent, there's no way I can recommend Panasonic's S1R over the A7R III. The latter is just as good as or better than the S1R in most areas, with the exception being slightly inferior resolution and video capability. Sorry, but that's not worth $1,200.

And pending my review, the A7R IV looks like a drastically better offering for the resolution-centric photography market, particularly given the $200 cheaper price..

.Panasonic will need to revisit the S1R's price, which is not competitive.. Otherwise, spend a lot less on Sony's A7R III or wait for the higher-resolution A7R IV."

Price is a complaint that I see thrown about regarding the s1/r. However for context....
It has 1dx level of build quality, has a buffer that clears incredibly fast, backlit buttons for working pro's in dark environments, top LCD panel, ergonomically balances larger professional fast glass, probably the best low light AF point to point performance of any FF camera (where all mirrorless resort to CDAF), it shoots 4k60p FF, incorporates the best Sony 5+ mp EVF going, shoots 6fps CAF with 14bit raw, 30 fps with 8 bit raw (put that last one in there for benchmarketing fun), focus stacking, in camera pixel shift processing, stop motion capture, in camera raw development, has (according to cinema 5d) some of the lowest rolling shutter in the S1 and S1R, high quality internal amps, 3 axis tilt rear screen...
I don't get it. On what planet is it not offering more for more money relative to the competition?! It's the first mirrorless I've handled that's built at 1dx level.

In reply to:

pro photo 2011: IMHO, it doesn't matter how feature-rich the current and future Panasonic FF cameras may be, as long as Panasonic doesn't incorporate phase-detection auto-focus, it is not going to cut it.

Panasonic needs cameras that auto-focus on a par with or better than the Sony A7 III. This is THE most important factor.

To be precise here, CDAF is most certainly NOT on the way out. Most all systems today use CDAF as a final precise focus lock. E.g. hybrid systems such as Nikon and Sony use PDAF to determine initial focus and then zone in via CDAF for final precise lock.
Panasonics' approach is (I believe anyway) a super smart one as it scales better with pixel density than simply adding more PDAF photosites that increase the risk of banding/striping/image artifacts.
Panasonic use the traditional CDAF (similar to Sony and Nikon). They also use DFD and in the current generation of DFD (going to call it gen 3 for the sake of argument, where Gen 1 was GH4, Gen 2 was GH5, Gen 3 is S1/R) they produce a series of depth maps that are fed to a machine learning model which use object and subject recognition as well as knowledge of these subjects to predict next focus point. In effect replace the PDAF part of the hybrid system with an elegant software/processing solution.

alucard1357: The S1 "Review" was a biased review with full of sony fanboyism score, I don't expect this one either.

I left the Sony ecosystem with the A7rii, A7ii (due to moisture ingress on the hotshoe causing he EVF to fail). Sony Vancouver had a back and forth with me over a number of weeks. In Canada where I live, temperatures can get pretty extreme and really test the camera under working conditions.
I've since rented (and wanted to consider going back to A7iii and a9) given that my partner also shots both A9 and a7iii.
However I've no doubt that the S1/S1R are superior cameras in many areas including low light point to point focus speed for weddings, receptions. On both systems I go to single point and turn off any face detect gimmicks preferring to make the decision myself in a sea of faces for which face to lock onto. The panasonic is notably faster in that regard and more precise. As for C-AF tracking, I've found the slightly 'wobble' to be a tiny bit disconcerting at first but something I've learnt to trust as 99% of the time when properly setup it nails focus.

LoneTree1: Most pro sports or actions shooters aren't using high megapixel cameras. Instead, they use Nikon's D5, D4, etc. So while it would be nice to have bleeding-edge focus on this expensive camera, it's not as critical as some think it is.

A7riv 10fps is based on 12bit raw output. Competition quotes based off 14bit raw files. If having higher FPS is important, put the S1R into 6k photo mode. 30fps C-AF with 8bit stills. I'm surprised that Panasonic doesn't play the benchmarketing game like their competition and dumb down the IQ for c-af numbers to impress reviewers ;).
Note also that the camera is usable after taking a number of stills. The NIkon Z and Canon EOS R are also useable when filling the buffer and clearing it. Try using an A7riii or a9 even that has a large buffer to clear!
On the AF front, Tony and Chelseas initial previewed the A7riv and demonstrated that the AF wasn't the jesus camera it was made out to be. Yes it detects the eyes and tracks lovely but only identifies where to place focus. When it came to actually focusing it fell short of expectations. Look, A7riv is a fine camera. The jesus camera it is not, neither is the S1/R. All have their pros and cons. It's important to look into implementation.

So the S1R has the best video offering of any high resolution FF camera currently available or to come including the a7iv (4k 60p FF with binning, s35 no binning) , full HDMI outputs, high quality audio inputs. Has class leading touch interface. Has a buffer that clears incredibly fast once filled as it uses Sony's professional XQD card slot so the buffer clears instantly and the camear is useable. A7riv still isn't useable and buffer is slow to clear from initial videos. And yet you suggest there are better FF high resolution options available? Where?!
On the dynamic range side it won't suffer with banding, striping? It's AF system is designed around a beefy processor and deep learning. Im sorry, but technologically (besides slightly slower burst rate to the Z7 - which I believe quotes its 9fps at 14bit raw) the S1R is the high speed mirrorless FF to beat IMHO. Nikon Z8 will be an interesting implementation of the Sony a7riv sensor but likely suffers with lower dynamic range to Z7.

I also hate to say that in terms of IBIS , the S1/R have been demonstrated to have class leading IBIS. It simply has more physical room to move the sensor yielding 6.5 stops.
4k60p video - only FF camera currently offering this.
PDAF and CDAF all have their pros and cons. For the purposes of video Richard Wong's latest test has demonstrated that the S1R tracking outperforms the A7iii when you allow the sensor to sample at higher frame rates demonstrating that the CDAF + DFD has potential to keep getting better as a focus system implementation.
I hope that DPreview will re-review this camera periodically as the focus system is based around a deep learning system that is supposed to be continually updated over the life of the camera. I'm interested to see what improvements are yet to come down the line. The latest 1.2 firmware provided a significant improvement in overall performance.

alucard1357: The S1 "Review" was a biased review with full of sony fanboyism score, I don't expect this one either.

A few considerations... The S1R dynamic range has been demonstrated to be practically identical to the D850, A7riii over at DXO (a7riv shows worse performance to the A7riii so I'm using the 7riii for the purposes of this point). However, both the D850 and S1R manage to provide more usable dynamic range as shadows do not start to band as you push heavy on the shadows. It's the difference between benchmarketing and pragmatica real world usable dyamic range and in that context it's class leading with the D850.
Another consideration regarding the burst rate. Panasonic measures burst rate at 6fps but with full fat 14bit files. Sony measures with 12 bit 10fps in their marketing blurb. Nikon and Canon measure with 14bit files as far as I'm aware. My point is that comparing the S1r with it's contemporaries isn't exactly like for like here. Heck you could swing it the other way and say it has 6k photo (i.e 8bit jpeg still output for continuous burst... that would make the S1r more capable).

GrapeJam: 4k30 8bit 422 in 2019? Really Sony?

Also it seems that it's Sony policy to have crappy LCD screen, sigh.

I believe it's still 4.2.0 internal not 4.2.2 as well :/
4.2.2 8 bit is only external and still 100 mbps.

shutter2013: Aside from the 61mp sensor resolution increase, I fail to see how it jumps to the head of the pack to be honest. Looking at it's natural competitors - A7riii, Z7, D850, S1R - it is a very compelling product from Sony but in my humble opinion, the S1R out punches this offering on the technical side.
4k 60p 150mbps 4.2.0 internal across the full frame (no crop), HLG photo, focus stacking, stop motion, time lapse, XQD for faster buffer clearing, top LCD and backlit buttons, similar 5mp OLED EVF @ 120fps, full touch screen menu interface, sensor is not prone to striping or banding. The 187 multi shift can be achieved in camera VS on a desktop PC. On the AF front for stills, Panasonic is demonstrating similar continuous object/subject/animal tracking and eye focus AI.

The latest 1.2 firmware test from Richard Wong shows huge tracking performance improvements in video to equal if not better the a7iii when sampling at 60fps!
I'm not knocking the Sony - it's a great camera but top of the pack maybe in some areas, but definitely not in many others. Again just my 0.02.

stevo23: $750? That seems high when the Canon 35mm f/2 is $549. I think the Canon used to be a few dollars higher? But then the Nikon Z mount is..cough cough...$850.

I'm excited to see the side by side comparisons. The Nikon Z 35 is pretty incredible across the frame performance.

if it can perform at least as good or better than that lens, then I think there will be many happy Sony shooters!

shutter2013: Hi Guys,

Firstly thank you so much for the hard work and a great review.

I hope you don't mind some social feedback/typo editing from your viewers :)

On the other features table...
https://www.dpreview.com/reviews/panasonic-lumix-dc-s1-review/2
The tables shows '12 fps (12-bit Raw, AE locked)'.
As of firmware 2.0 , the z6 can now shoot 12fps raw with autoexposure on each shot.

The table also does not show that the Sony A7iii shoots at 10fps in compressed 11bit +7 raw.

Regarding video features, the table suggests that Nikon only supports 4k30 however it also supports 4k24p and 25p as well as 10bit external. Raw external recording has been announced by Nikon

Other than that, great read and the Panasonic is a great camera.

I apologize, I was wrong on the A7iii spec. I incorrectly assumed Sony were using the same 11+7 mechansim to inflate frame rate and buffer depth similar to A7ii, A7rii lines and cameras that had come before. No offense intended.

For DPReview to update their tables....
The Nikon does 12bit @ 12fps and 14bit @ 9fps.
https://www.imaging-resource.com/PRODS/nikon-z6/nikon-z6A6.HTM

The Sony does 9.7fps with uncompressed raw.

The question isn't whether you own the camera or not - it's not really irrelevant what you, I or anybody else owns for the sake of this conversation.
What is relevant in the context of commenting on the cross brand comparison, is that if presenting spec sheet details for one brand of camera in a cross comparison table, then the same level of detail needs to be applied across all brands. Clearly this wasn't the case here... where the 'caveats' of the Sony are not shown and details for Nikon are out of date relevant to the latest firmware update.
In this instance, 12bit continous Nikon is akin to the 11+7 Sony approach.
FWIW I agree with you totally that a reduced raw file bit rates only helps from a pragmatic point of view, but again I don't feel that's relevant right now.
The only thing I am advocating for is that the same approach and level of detail for cross spec sheet presentations is taken irrespective of brand loyalty :)
