LUMIX S1 AutoFocus AF-C Studio LIVE Test for Video by @PhotoJoseph

[@hagentrondheim3675]

Really precise and honest test. The AF is good. Love the skintones and general color feel.

[@photojoseph]

Thanks!

[@nickcage9686]

@@photojoseph Why are STILL pushing this phony shit? Contrast Detection Focus sucks, AND everyone else's tests how this. Why don't you just push Panny to adopt Phase Detection AF like everyone else. Why are they so fucking stubborn... and you too? Stop the bullshit and spin. It's sickening.

[@KevinLe]

Holy hell! That body looks massive with that battery grip!

[@adilovaziz]

Really good and honest review of the AF system. Keep up the good work.

[@artistcharlesmaring]

It's not perfect, but we are loving it, and using it all the time. Something we didn't do with past systems. Thanks for sharing!

[@aquissuk]

Loving the production quality of recent videos. Intros and Outros pop. Just feels like you have moved things up to another level 👍

[@photojoseph]

Thanks man! That’s the idea. Definitely adds more time to production though. Tough balance.

[@jeffchiu8146]

That was a honest review and entertaining enough to hold me. Thanks for the review

[@photojoseph]

Thanks for watching, and I'm glad you enjoyed it.

[@my9221]

Superior video love it!

[@LetsBuildThatApp]

I think we're also interested in seeing if this will hold focus for talking head videos. From the live show that Gerald Undone did, you can see the S1 fails quite miserably at maintaining usable focus.

[@charbax]

Hi I hope it's better than my G9 for sure. But I think handheld (fully using the Dual IS) is a better test, and not just with a mostly black background, that's making it too easy for the contrast based AF I think. It needs to be in the streets and with non studio lighting with variable lighting conditions that aren't just fully controlled nor necessarily as contrasty. Handheld camera movements with subjects and objects filmed also moving.

[@TheAndyroo770]

It's just ok to be fair. Probably on par or a little worse than the competition. Would love to see it really tested with an f/1.4 lens if there is one for this system. Also Canon lenses via adapter test (if possible).

[@clifftotten7609]

I own a GH5, S1 and S1H. (I loved the S1 so much I was going to sell it after I got the H but wound up holding it) Anyway....I think with Panasonic using a contrast based AF system while almost the entire rest industry has licensed PDAF sensors...is an amazing story. The simple question "why?" is appropriate here. What is going on? Sony Semiconductor licenses PDAF sensors to Nikon, Olympus and Fuji but NOT to Panasonic. The two theories are: 1.) Panasonic only wants to pay for Sony non-PDAF sensor licensing. 2.) Sony wont license PDAF chips to Panasonic at reasonable prices! (#2 is what I'm being told) Very few people know which one is truly correct but I believe it is fair to say that AF is the #1 reason that hurts Lumix sales. I'm a true Panasonic fanboi today. I left Sony PDAF for Panasonic colors, codecs and 10bit color. But,...I'm a RARE customer. The average Joe would NEVER leave Sony or Cannon PDAF behind in favor of contrast AF. This will always be the "elephant in the room" when talking about how great Panasonic cameras are. If Panasonic were able to license Sony PDAF sensors,...their sales would DOUBLE or TRIPPLE what it is today. So, again....."why"? What is going on behind the scenes here in the industry camera wars?

[@photojoseph]

I wish I knew! But thanks for being an arrant supporter. Fortunately AF is not the most important thing for many customers. But I don’t disagree with you.

[@clifftotten7609]

​@@photojoseph - Last year, there have been some "changes" that happened between Sony Imaging and Sony SemiConductor. Let's see if Panasonic have been able to "negotiate" the licensing of Sony PDAF sensors for the three new GH6 series cameras. "If" they can?....we would see Panasonic sales numbers skyrocket. The last thing we want to see is this tag line; "Panasonic - For those who care about everything except AF" I just cant see Panasonic being the ONLY company left out of PDAF. If Sony wont play ball and sell to Panasonic at a reasonable price, Panasonic needs to get regulatory agencies involved. Anyway. The GH6 series can't survive for 3 years without PDAF or at least ToF (time of flight) AF. Panasonic contrast DFD wont carry their cameras for 3 more years until the GH7.(not against Sony, Cannon, Nikon, Fuji and Olympus all licensing Sony PDAF chips)

[@redbit6182]

I don't know why Panasonic is stuck on contrast based autofocus, but did you ever heard about striping artefacts of Sony phase detection sensors? and about the fact that every single photosite of Canon sensor is splitted in half? one half for autofocus and the other to get the actual light that will form the image, the side effect is probably a noise increase and a dynamic range decrease. the whole youtube is praising the speed of phase detection autofocus, no one is talking about its technical disadvantages ...

[@sayharris1361]

Thanks ☺️🙏🏽

[@proteus1]

The best camera reviewer on KZbin PERIOD.

[@JCANPetros]

Auto focus seem pretty decent...definitely usable.

[@proteus1]

Try the 50mm lens..See if things improve. Be interesting to see the outcome.

[@rodvisionfilms]

I have the latest firmware but, I really wish I could achieve fast focus (people or objects) with my S5 using a no native lens (Sigma 24-70mm 2.8). When using a slider for example, having an object in focus and moving camera towards the object trying to do a product ad is just painful because auto focus is useless so I have to compensate with manual focus which cannot be precise at all.

[@sayharris1361]

I have to ask when are you going to do the autofocus test. For still photography with some canon L glass or with the Sigma 60-600mm lens please🙏🏽

[@photojoseph]

The Sigma L-mount / Canon adapter isn’t shipping yet so that would have to happen first, but I would never expect AF to be great on any adapted lens, so what’s the point? Native glass is where you’ll get the best performance. But, I do own a lot of Canon glass still so once I have an adapter, we’ll see.

[@valepandrums]

LOL at 3:00😂😂thx for this test I got S1 since two week and I found animals , people face detection the best IMO

[@photojoseph]

Thanks for laughing at my pain! 😂😂 Seriously, good to know you’re finding the mode working well too!

[@proteus1]

Are you doing an update on auto-focus on the S1 NOW WITH NOV 19 UPDATE.

[@photojoseph]

Wasn’t planning on it, no

[@DoubleGauss]

Great technical review. Thanks for doing the test. When the subject is far from the camera, the focus is fast enough. Not great but fast enough. However when the subject is close, especially with longer focal lengths > 50, the lag is unacceptable. Presumably this has to do with how much the lens has to turn which is greater at close distances and longer focal lengths (why macro lenses have long barrels). This is not up to par with Canon's DPAF. My five year old 7D mk ii focuses faster than this. I got an S1 recently which I think is a phenomenal camera in every other way but focus tracking will remain its weak(er) point.

[@TheUlitamateStunt]

The electronic focusing mechanism is not the issue with the near-focusing on the S1. I believe it is primarily to do with the fact that DFD fundamentally needs to pulse the focus in order to know where to go, but to hide the distracting pulsing Panasonic has massively slowed it down in video mode to make it almost imperceptible. The result is smooth, accurate, but trickle-slow AF. DFD is fast, sometimes faster than PDAF, sure, but only in good light with good subjects in photo mode with wide aperture lenses and even then only 90% of the time.

[@vc6218]

Will this not work with the sigma adapter for Canon Lenses?

[@clifftotten7609]

Interesting. I have been playing with my S1H endlessly with different setting. I adore this camera but I'm trying to figure out if I can trust it yet in AF. I'm getting there one test at a time! I have found that slowing speed and lowering sensitivity will help with depth of field focus pulsing in the background.

[@photojoseph]

Nice, keep us posted! I've had pretty good luck with it but TBH I do almost all video work in manual focus ;-)

[@clifftotten7609]

@@photojoseph The app is a great way to use manual focus and tap on yourself if you are in front on the camera and have nobody to focus for you. If you are in a crowd and have to hold the camera high over your head "paparatsi" style on a politician, the S1H on the 24-105 seems to be pretty much OK. (Basicall)

[@photojoseph]

Yeah!

[@deanwaterman]

Looking, cannot find, the ability to adjust sensitivity? Joseph referenced, as have others; but I cannot find it on the menu. I’m sure it’s an easy miss. If someone sees this, assistance appreciated.

[@proteus1]

I may be getting the s1, I'm wondering if it will be compatible with the Ziyun Crane 3. An update in firmware will be available in the future on the s1. Hopefully the tracking will be better. 14 stops is a good thing about this camera too.

[@hanuman918]

Does the black background helps improve the camera's face detection?

[@photojoseph]

No, that’s just what my studio looks like

[@hanuman918]

[@JonathanPrawiromaruto]

Hi, my video auto focus only works when i pressed half of the shutter. How do i turn my auto follow focus on? Thanks!

[@photojoseph]

There's two AF modes; 1 and 2, somewhere in the settings. One does AF all the time and the other only does it while recording. One is to save battery but the other is in case you're using an external recorder.

[@shapecleveland3252]

Odd question at this point, but thank you for the video first off. I was wondering how you had those menu tabs on your screen on the right side. I'd love to have more controls available. I honestly had a hard time even finding the face detect that you had pulled up as well. Thanks!

[@photojoseph]

Menu: Gear > Operation 1 > Touch Settings > Touch Tab

[@MrBorderman01]

Does anyone know how to check for the shutter count on the S1? Thnx

I have a pana S1. I am really satisfied of the picture quality & ergonomics. I have just a strange issue. The autofocus in video mode is not working at all when there is no HDMI plugged in ?! Did you have to setup something specific in the menu ?

[@photojoseph]

AF only is happening while the camera is recording. But when you connect HDMI, the camera doesn’t know what’s in the other end, so it enables AF all the time.

Hello Joseph, I got Yesterday my new S1, it's a huge camera but fits perfect to my hands, but I can't open the RAW files in Affinity Photo nor in Luminar 3. Do you know something? I am a Windows User. How do you edit raw files? Thx a lot! Jog

Those companies may not have added raw support on windows yet. You’ll need to check with them.
