Finally got around to diving into the Panasonic/Lumix S1R firmware update and assessing the new features. Some were surprising. Surprisingly great!

Here's a link to the video on Vimeo: https://vimeo.com/492645355

You know how you can sometimes get really busy with lots of pressing details and you've upgraded something, made sure it still works, and then moved right back to getting your ongoing and not-related details sorted out? Well, that's where I was with the S1R. I did the firmware updates for all three of the S1x models and then turned my attention right back to finishing up jobs and doing year end taxes. I shot a few still frames on the S1R, determined that it still made nice photographs and then put it back in the drawer where it normally lives. 

This morning though I stumbled across a video that outlined the differences in feature sets between all the full frame, Panasonic S series cameras and it immediately became apparent that I had not spent enough time understanding and testing all the goodies that were bestowed on the S1R at the time. 

The video above is about 15 minutes long and might bore the socks off you. On the other hand it's a sample of what you might expect to get out of your S1R in terms of how well it focuses on me throughout the video, how much detail is retained in the files and, the charming image quality of the video.

I don't want to cover every upgrade to the camera because only a small subset of you own that camera model but I do want to call out a couple of major, and newly acquired, feature improvements. 

Or, you can sit back and watch me ramble on in the video. But if you are looking to make visual quality judgements I'd suggest you click on the link above to Vimeo and watch it there after selecting the largest available size. 

Focusing: I've always found the Panasonic S1 cameras to be very fast to focus but that's probably because of the way I use them. I'm fond of single AF and equally fond of selecting a single focal point or square to use. If you use continuous focusing with back button manouvering your experiences in the past will no doubt be different than mine. 

But what people complained about 90% of the time was the just average performance of continuous autofocus in video. That the cameras were slow to lock on and had a tendency, in non-optimal situations, to hunt or pulse. Panasonic true believers hemmed and hawed and talked about how "real" cinematographers only used manual focusing lenses anyway. Well, even I know that a whole new generation of film makers are thrilled to use continuous AF for their projects. One of my best friends made that a primary consideration when recently upgrading his gear from a Sony FS7. 

After the firmware update I believe that the S1x cameras have become much more competitive with their C-AF focusing. But instead of taking my work for it just go look at the video I posted. There's no "pulsing" between the foreground subject and the cluttered background. None that I can see, anyway. And the camera goes from out-of-focus to nicely in-focus smoothly and without any obvious over-shoot and re-focusing. I thought the results were confidence inspiring and will consider using C-AF for on-camera interviews, going forward.  

So, that's the first big feature set, which I approve of, but I will add a caveat. Many users are experiencing some interference in focusing performance when working under flickering, non-continuous light sources. Mainly fluorescent lights and cheap LEDs. These conditions make focusing much slower and sometimes inhibit focusing altogether. Yikes. 

I haven't experienced this but enough people have written about this that I felt duty bound to report it. 

5K video: For me this is the biggest improvement. Right out of the box the S1R had the poorest selection of available file options for video. You didn't have the choice of selecting .Mov. You could only work in M4p. There were also no options for 10 bit color depth and nothing beyond 4:2:0. Still, the files coming out of the camera in 4K looked good. It's just that the paucity of higher data rate files reinforced the idea that the camera was more squarely aimed at photographers and that most everything else about the camera was merely a polite nod to hybrid users--- and Panasonic's camera heritage.

The update delivered a new choice. Now you can shoot in 5K and you can do so with 10 bit color at a data rate of 200 Mbs. The camera delivers tons of detail but it does so in an odd aspect ratio. The native 5K files at 30p or 24p are 4992 pixels by 3744 pixels. It's a much more square-ish format than we normally expect to see out of a consumer video camera. But it works. Go look. 

The 5K files are only available as .Mov files and that's fine. The increased bit depth and higher overall resolution mean that your final video, exported as 4K or 1080p is going to look great. Really great. 

If you want to stick to 4K the S1R has some interesting new advantages there as well. You'll be shooting in M4p but if you want to shoot at 60p you'll find that instead of mandating an APS-C crop as is required by nearly every 24 megapixel camera shooting with current Sony full frame sensors (not fast enough read speed to write our the full width of the frame!!!) you'll have only a 1.1 X crop with the S1R at 60p. And that's almost no crop at all. You'll get the nearly full advantage of the format all the way up to 60p and that's while writing to an internal memory card. 

There's also a bonus level. Go into the HDMI menu and you can choose to write to the camera at 8 bits or to an external recorder at 60p, 10 bit, 4:2:2. And you still get almost the full width of the sensor there too. If you take the clean signal out with the HDMI and write the files at ProRes 422 you'll also get the advantage of an ALL-I codec. Suddenly the S1R goes from a good video tool to a great one. 

The final bonus of using the external recorder is that you lose the 20 minute, 4K time limit. The system will run as long as the camera battery and memory card are able. Pretty sweet!

And while you are in the video mode you can also set the camera to show shutter angle instead of shutter speeds. It's a quicker way to work and helps assure that you are in the right setting for good, clean, jitter free video. Sorry, no wave forms...no vector scope...

With the update the cameras shares an exclusive feature with the S1H (which I actually consider to be the system flagship). If you use the XLR audio adapter from Panasonic the new firmware unlocks "High Res" audio. You can record your audio at a much higher sampling rate which should improve the sound and decrease noise in the files. Go ahead and listen to the sample I created and see what you think. It's not available on the S1 or the S5...

I'm very impressed that Panasonic took a camera I already liked a lot and made it even more valuable to me. Like all the S1x cameras the S1R has a full sized HDMI which makes me want to connect it to my Atomos recorder along with headphone and microphone jacks on the body. I'm very happy right now. If you just updated your S1R you're probably also happy. Ah, happiness. Fleeting but tasty while here. 

So, that's what I experimented with today. Thanks for all the comments on yesterday's post. Seems like many of you have found great ways to work around the pandemic. Gave me hope and a smile when I read the comments. 

Video notes: The video I embedded and linked to was created in a small corner of my office. Everything you see is unedited, not color graded, not corrected for exposure or tonality. It was recorded directly into the camera so it's 5K, 10 bit, 4:2:0. The audio is 96kHz. I shot at f2.8 and 2/3rds of a stop with a Sigma 45mm f2.8 L-mount lens. The scene was lit with a single 500 watt tungsten light in a Lowell Tota-Light fixture. 

So, both the audio and the video are absolutely STRAIGHT OUT OF CAMERA. No monkey business. No LUTs and no Log files. Nice to see the camera delivers so well with so little intervention. 

Next time I'll try to find a more glamorous on camera model. This one was definitely not cute enough. 

Thanks. KT

Hi, Kirk.

I'm in a somewhat similar situation, having just retired in early August of this year. I'm a complete rookie, but slowly finding my way navigating the additional 50 hours a week now at my disposal. It's a wonderful problem to have, and with my wife still running her non-profit, I'm in a much better position to give her more behind the scenes support than what I was able to provide pre-retirement. The other time is now spent bicycling when I choose instead of when discretionary time allows, and working around our properties at a more leisurely pace during the week, instead of trying to be the weekend warrior and get everything within a 48 hour time span. I guess my point is we all have more than enough to do just trying to manage our own castles, so, when blessed with the opportunity to slow it down a notch or two, make the move to do so and figure it out along the way. Life will always step up in one manner or another to fill our days. I suppose the sweet spot is having a little more discretion in how it all plays out.

Enjoy your semi-retired status, Kirk.

Hopefully I'm not breaking protocol and posting a second comment, but wanted to share this while thinking about it:
I suppose I'm also in the minority of users who've bought into the Panasonic S series. I wasn't too concerned about AF-C when I originally purchased my S1, as I only planned to use it for landscape and portraits, where I use AF-S exclusively. I also wanted the 24 MP sensor for its dynamic range, but also the option for 96 MP resolution. I also appreciated it being full frame with no AA filter, which makes a measurable difference with both landscape and portraits. That said, video wasn't even a consideration at the time, as I was using two Fuji X-T3's for all of our video work.
I started experimenting with the S1 to see just what might happen. Right away I did notice my S1 struggled at times with the AF, yet it wasn't the unusable nightmare I'd so often read about. And many of the comments suggested Panasonic native lenses work better in every regard than third-party lenses when using AF-C. I don't know since I have only the Panasonic 24-70 f/2.8 and 16-35 f/4, which do work quite well with AF-S.
Prior to updating my S1 to the version 1.6 firmware, I experimented with the focus sensitivity and speed settings, and was happy to discover they have a measurable affect on focus performance during video. Our video work is more vlogging style with the occasional talking head, so after playing around with settings we settled on Speed 4 and Sensitivity 2. These settings give us the desired focus acquisition and speed we prefer in what is often a rapidly changing scene. If there is any of the dreaded 'pulsing' we haven't noticed it. We've discovered if we leave the settings at or near the default settings, focus is just too slow for our needs. After updating to Firmware 1.6 we noticed an improvement to both the focus acquisition and retention.
Perhaps our content just doesn't challenge the AF, but we shoot in almost all situations with quick changes in composition, and quite frequently in low light. The only area we've experienced any difficulty is with harsh back-lighting, where apparently there is little detectable contrast. That said, I've read even phase-detect systems have this same challenge in these situations. My X-T3's seem to work better in these situations, but we've learned to just avoid them if at all possible. Interestingly enough, if the back-lighting is extreme the S1 has no problem identifying the silhouette after the Firmware 1.6 update, and will hold the head and/or body silhouette in perfect focus. Go figure.
We've recently purchased an S5 to accompany the S1, and have both set identically for AF Speed and Sensitivity. Both seem to work very similar in all situations. So, I suppose our experience is at odds with most everything we've read and heard regarding the S-series video AF. I should also mention we shoot 4K and 30 fps. We do not need a 'cinematic look' for our work, so perhaps the slightly higher frame rate, vs 24 fps, does increase the refresh rate of the sensor and improve AF performance. I dunno'. But we're enjoying our foray into using the S1 and S5 for video. The files are just amazing, and we do enjoy the Panasonic color science. And the on board pre-amps are sweet.
I apologize for the long rant, but wanted to share our experience with the Panasonic system. I followed your lead and have been very pleased. As always, I'm enjoying following along with your experiences and appreciate your sharing so much information. Always an interesting journey.

Panasonic has a web page https://www.panasonic.com/global/consumer/lumix/technologies/af.html
where pdfs for both the S1X and the gh5 ghs5 g9 are located. Both are about Cf. Can't speak to S1X pdf; is longer and the S1X gets a few more functions but the M43 pdf is very helpful. You can futz with the settings to get rid of the pulsing under led lights, adjust the rate of focus change, etc.

I use SAF w/back button almost all the time. I still think the hack that kirk came up with is simpler. Be in SAF, and use the touch screen to change your focus point.

Say, that was great! Seen on my older 27-inch non-Retina iMac it was as if you were just sitting on the other side of the desk talking in casual conversation. For a 15-minute unscripted presentation, that is no small achievement.

I watched it embedded in the blog. Right-sized on the native resolution of this screen and sharp as anyone could want. No need to move on through to Vimeo for higher quality. Maybe something to keep in mind for clients later on. Apparently there have been upgrades to blog providers' embed video streaming.

The sensitivity and speed of focus settings work very well. Somehow the combination you've set gets past the Panasonic's chronic problem of having to overshoot for just a tiny fraction of a second, then back up. I guess you can't have "depth from defocus" without a defocused image to compare to, but in this case interval has been shortened to the point where I no longer see it.

All-in-all a very satisfying 15 minutes, at least from this side of the screen.

WOW!! I got to see Mr.T in person and hear him speak! How uber KOOL is that. Well done and very informative video Sir, even though I don't own any Panasonic gear.

Do have an EXCELLENT Safe and Happy Christmas.

I think everyone is missing the point. That audio was (except for the break when Tuck moved in close to camera) pretty much nuts on perfect. Just perfect. I can hardly believe when he says it was straight from the camera.

Hi Kirk -
Great to see you alive :-) on video and hear you with perfectly clear audio.
I want to say thank you for all your posts this year.
You can still write more than I can read so I get to choose which posts to dive into.
Wanted you to know that I (and I guess many more regulars) am reading your posts daily, and learning new technical stuff, and about your life in Austin TX USA.
Please forgive for not commenting enough.
I wish you and your family and the VSL readers community happy holidays and a happy 2021 new year.
Best Regards - Yoram
