Lumix GH6 will do 120fps 4k & maybe more!

Lumix GH6 Panasonic

Panasonic unveiled in May the GH5 Mark II which is a slight refresh of the venerable m4/3rds GH5 with live streaming, better dynamic range in video, better AF algorithms, and slightly better IS on a very similar body with just a few cosmetic red buttons and rings for refresh purposes.  The slow motion remains at 180fps VFR at 1080p and 60p at 4k on the GH5 II since it is using the same sensor and imaging engine. It is a better overall camera than the original but a mild refresh nonetheless. 

That brings us to the pre-announced GH6 which is an in-development camera that aims to refresh the entire Micro 4/3ds line in Panasonic and aimed at professional video users.  It sports a new sensor, new imaging engine, new body and new technologies yet to be disclosed.  According to rumors, this camera should be able to keep micro 4/3rds alive for another five years delivering an array of video and photo features that will set it apart much like the original GH5 carved a place in camera history. We have also received rumored specs that may or may not pan out regarding frame rates which we find somewhat credible.  → Continue Reading Full Post ←

Panasonic S5 Slow Motion 180fps is Low Res!

Panasonic S5 Slow Motion

Now that Panasonic has officially announced the Lumix S5 Full frame camera which we saw as a direct replacement for the GH5 line even when now it seems a GH6 may be in the cards for a future release, it is now time to examine the slow motion modes on the camera to see if they stand a chance at becoming a feature which will be a seller for the new device or just one more feature.

When the GH5 was announced about 3 years ago it came with a 180fps 1080p mode that was better than many camera’s 120fps modes and quickly became our favorite Lumix camera for slow motion as we noticed how the quality of the 240fps mode on the GH5s low light geared camera was heavily inferior in resolution. The GH5 really became the best value along with the G9 for 180fps slow-mo modes in Full HD.

Panasonic Lumix S5 Main Features:

  • 24.2MP Full-Frame CMOS Sensor
  • UHD 4K60 Video,10-Bit Internal Recording
  • 120p, 150p and 180p Full HD Modes*
  • Slow Motion AF Tracking up to 150fps in Full HD!
  • V-Log, HDR, and Dual Native ISO
  • 2.36m-Dot 0.74x-Magnification OLED LVF
  • 3.0″ 1.84m-Dot Free-Angle Touchscreen
  • Contrast-Detect 225-Area DFD AF System
  • 5-Axis Sensor-Shift Image Stabilization
  • ISO 100-51200, Up to 7 fps Shooting
  • 96MP High-Res Mode, Dual SD Card Slots
  • MSRP: $1,997.99  Body Only or $2,297.99 with 20-60mm Kit lens!
  • Pre-order includes a Free Sigma 45mm f2.8 Lens Via Mail-In Rebate

First the Good:

The 24MP sensor is excellent in low light, it will perform extremely well compared to Micro 4/3ds or APS-C cameras but it will not beat the low light king of cameras the Sony a7s Mark II or III.

The camera can shoot 10-bit internal up to 60fps but it will have an S35 crop at the 60fps 4k mode.  The sensor stabilization is not the best out there but it is quite got at up to 6.5 stops with sensor+lens correction.

If you pre-order the camera you get a free Sigma 45mm f2.8 Lens via mail-in rebate which seems either overly generous or somewhat suspect of fear of people jumping ship to other systems.  We feel this is a pretty good deal especially if you also get the kit lens as that one is over $300 USD discounted if you order it with the camera.

From the samples, we have seen the quality in stills and video is as good as the S1 and S1H with very impressive color characteristics that are as close to the Canon color range as we have seen.  Panasonic has done an excellent job with their color science since the GH5 and it shows how good it has become here.

The Bad:

We get the DfD Autofocus system with no Phase detection pixels which in our view are the only way to go for reliable video AF.  In the early tests, it seems to do quite well compared to previous Panasonic Efforts and most of the pulsing is gone in people tracking scenes.  However, the really depressing thing is that the reliability is not a 100% some would call it 80% or even less which means you simply cannot rely on it for mission-critical footage.

If your camera can only have in focus 8 out of 10 shots then you cannot rely on the video tracking AF for paid work.  Most footage is recorded with the expectation that focus can be controlled, if it fails then you lose time in production and worse yet if you find yourself in the edit suite a month later looking at out-of-focus OOF shots on your edit bay, then you have a huge problem on your hands.

Panasonic needs to stop clinging to DfD as their single do-it-all AF solution and change to a hybrid Phase+Contrast AF system like Sony or Canon are using.  This continues to be the Achilles heel of the system and they need to own up to their mistake not double down on it with every camera release.

For many users, the AF on the camera is good enough and many Vloggers will shoot with it just fine but professional videographers will need to go to Canon or Sony for reliable AF as even the flagship Panasonic S1H suffers from even worse DfD AF performance.

What about the Slow Motion?

Now on to our website focus, that of slow motion video. The Panasonic Lumix S5 is capable of 60fps 4k video at 10 bit with an s35 crop in the sensor at that mode and also a cropped 150 and 180fps mode in 1080p Full HD recording.

The good news is that now we have AF tracking up to 150fps in full HD. The bad news is, it is contrast-detect DfD which means the same problems as the regular mode. But in practice, higher frame rates offer better AF performance as the camera samples more times/sec so it can lock into subjects better!

Slow-Mo Modes & Bit Rates:

  • 4k 60fps 10-Bit Internal
  • 1080p 120fps, 150fps slight crop and resolution loss.
  • 1080p 180fps – More severe crop and resolution loss.
  • H.264/MP4 4:2:0 8-Bit
    UHD 4K (3840 x 2160): 23.976p/25p/29.97p [100 Mb/s]
    Full HD (1920 x 1080):
  • 23.976p/25p/29.97p/50p/59.94p/100p/119.88p/180p [20 to 28 Mb/s]

So we now have what could be the let down of this camera and that is the low bit rate quality in 1080p slow motion of [20 to 28 Mb/s].  That is the exact same bit-rate as that on the 3-year-old GH5 camera which is not ideal. It is also more of a 720p image up-scaled to 1080p which looks aliased and soft.

We rather have a 100Mbps mode like that possible on regular up to 30p and 60p full HD recording modes.  Slow motion is crippled by using one-third of the bit-rate allocation in what we believe would be related to camera memory due to the faster frame rates. However, the S5 has a massive memory buffer that should easily be capable of recording 100Mbps 1080p at 120, 150 and 180fps options.

The excellent video preview by DPreview below at 11 minutes 7 seconds shows the slow motion mode samples in action with a heavy resolution loss at 1080p 180fps.

Panasonic S5 First Impressions Review by DPReview:

Another sample below shows many more slow motion clips which seem to be at 150fps which offer Continuous AF in Slow Motion up to that point. 180fps will not use AF. Forward to 7Min for the samples.

Lumix S5 Will be a Full Frame GH5 equivalent for $1998

Lumix S5 Slow Motion

The Lumix GH5 is still one of the best video powerhouse cameras ever produced. It doesn’t overheat, it shoots incredible 4k oversampled video at up to 60fps 4k or 180fps 1080p with near Full HD quality but it’s Achilles heel, the Micro 4/3ds sensor which is small and quite inferior in low light compared to Full Frame or even APS-C rivals.  The GH5s is the low light lower megapixel version with dual Gain senor which is actually very clean in low light and can go toe to toe with the best out there but has no IBIS which is a big loss.

Now Panasonic is set to announce the Lumix S5 Full frame mirrorless camera which essentially migrates most GH5 features into a full-frame body with nearly the same introductory price of $1998 USD but improves 4k 60p with 4:2:2 color at 10-bit instead of 4:2:0 8 bit on the GH5. You get IBIS, and also the 180fps Full HD of other S L-mount cameras by Panasonic.  It is still too early to tell what kind of quality the 1080p 180fps mode will be capable of but it does hold promise as the S1H and S1 do a pretty good job on these modes.

Lumix S5 Announcement Very Soon:

The camera will be unveiled Wednesday, September 2, 2020, at 14:00 UTC at the official Lumix site here: https://www.panasonic.com/global/consumer/lumix/s/s5.html

We also expect to see new low-cost L mount lenses for the system that will make the camera more appealing.  We just have to wait a few more days!

But what about the AF?

Yes, the dreaded DfD Depth from Defocus algorithm based on contrast detection is also present on this camera which means it will probably be inferior to systems that use dual pixel AF based on Phase and Contrast hybrid modes which are especially good for video. That means Sony and Canon will still have the upper hand here. Panasonic should keep DfD as an option but make cameras with Phase-detection AF pixels to be able to fully compete in this market. They are doing incredible hybrid still and video cameras with one feature missing, if they fixed the AF they would probably be the first choice of video professionals considering how good the cameras perform. Sadly Sony seems to be eating their lunch with the newly announced a7s Mark III with an AF system that rivals the best out there, in fact, it is so good that you can forget about focus pulling for most shots. The same cannot be said of the Lumix DfD AF contrast system.

We expect the 180fps Full HD Quality to be as good as the one in the S1H camera of the Lumix System. See this video to see the expected quality:

Fuji X-T4 Slow Motion is the new king of APS-C!

Fuji X-T4 Slow Motion

At the end of February right before the Pandemic really got going worldwide and when the world seemed a lot simpler, Fuji surprised us with the launch of the Fuji X-T4 APS-C 1.5x crop sensor body.  It comes completely unexpected to the community of slow motion enthusiasts as the majority of cameras only support a maximum of 120fps with a few Panasonics doing 180p and only the GH5s doing 240fps 1080p.

What makes this camera different is the quality of the output at 240p which is far and above the king in the APS-C format and destroys the GH5s aliased image with a very good and detailed rendition of the scene with a codec strong enough to allow for enough detail and color to really push the format further than any EVIL mirrorless camera before it.

Fuji X-T4 Slow Motion Video Modes:

Recording MOV/H.264/H.265 10-Bit
DCI 4K (4096 x 2160) at 23.976p/24.00p/25p/29.97p/50p/59.94p [100 to 400 Mb/s]
UHD 4K (3840 x 2160) at 23.976p/24.00p/25p/29.97p/50p/59.94p [100 to 400 Mb/s]
DCI 2K (2048 x 1080) at 23.976p/24.00p/25p/29.97p/50p/59.94p [50 to 200 Mb/s]
Full HD (1920 x 1080) at 23.976p/24.00p/25p/29.97p/50p/59.94p/100p/119.88p/240p [50 to 200 Mb/s]
External Recording Modes 10-Bit
DCI 4K (4096 x 2160)
Recording Limit Up to 30 Minutes
Video Encoding NTSC/PAL
Audio Recording Built-In Microphone (Stereo)
External Microphone Input (Stereo)
Audio File Format AAC, Linear PCM (Stereo)

Still Imaging Specs:

Lens Mount FUJIFILM X
Camera Format APS-C (1.5x Crop Factor)
Pixels Effective: 26.1 Megapixel
Maximum Resolution 6240 x 4160
Aspect Ratio 1:1, 3:2, 16:9
Sensor Type CMOS
Sensor Size 23.5 x 15.6 mm
Image File Format JPEG, Raw, TIFF
Bit Depth 16-Bit
Image Stabilization Sensor-Shift, 5-Axis

So we get the usual 120fps NTSC and 100fps PAL formats you have come to expect on most other cameras and then jumps straight to 240fps at what seems like 200Mbits/sec according to the specs (Further testing needed) listed on the official site.

The camera also has a 6.5 Stop 5-Axis IBIS sensor stabilized system that from what has been tested is right up there with the best Panasonic and Olympus systems.  Fuji has really created the best APS-C camera it has ever made here for the enthusiast and maybe the best in the format ever released for videographers and at 15fps and Phase Detection enabled 425 AF points for photographers; it is no slouch.

Fuji X-T4 240fps Sample videos:

Here are some initial samples that show the 240fps slow motion mode at 1080p.  We believe this will be a camera to consider for high frame rate enthusiasts that want to shoot sports and people/animals in pretty remarkable quality while at the same time having a do it all video and photo camera with the Fuji quality behind it.

Canon EOS R5 Rumor Hints at 120fps at 4k!

Canon EOS R5 Rumor

Quite a few of our readers have asked for HSC to comment on the rumors of a Canon R5 Mirrorless camera that according to unsubstantiated information claims 120fps at 4k and 8k at 30p.  The R5 may be the modern non-DSLR successor camera to the EOS 5D Mark IV and could become a major release for the company for this decade.  As rumors go we can probably believe some of it but we have to be skeptical on the full specs because Canon has not shown the willingness to push the envelope as far for many years and has calmy let Panasonic and Sony take the firsts spots on video features.

We would love to see Canon go ahead and push the envelope with amazing video features that can revive the platform for serious video production the same way the 5D Mark II did back in 2008 when it took the video world by storm and made it possible to shoot quality video that looked a lot like the 5D still images that have dominated certain segments of still imagery business like weddings.

Canon EOS R5 Rumor Specs by “Canonrumors.com”:
  • 45mp (One source said 40mp)
  • IBIS
    • 5 stops with IBIS alone
    • 7-8 stops of correction when used with in-lens stabilization

    14fps / 20fps (One source said 12fps / 20fps)
    Scroll wheel added to the back
    No touch bar
    Liveview/Movie toggle like previous EOS DSLRs
    Larger capacity battery, but looks like the LP-E6
    8K @ 30fps RAW
    4K @ 120fps
    4K @ 60fps
    The info I was given about a crop was confusing
    Announcement ahead of CP+ next month

    So let’s dissect the above information…

    -45MP FF Sensor seems plausible but we probably will see a 50MP sensor with a 48.x effective pixel count. Big area and hi pixel count sensors are not ideal for high-speed video, so this is another hint at the rumors being a wish-list.

    -The IBIS in-camera system is a little suspect considering the reliance of Canon to tout their lens IS systems which are a major selling point for the platform but they have already showed a patent with IBIS for the EOS M platform which should be introduced soon enough. They cannot keep ignoring other brands having excellent IBIS and dual IS systems like Panasonic Dual OIS which really kills the EOS system on stability performance.

    -Frame Rates:  120fps 4k? color us skeptical but the fact that only the very best and expensive canons do 4k 60p at most will probably mean that as a first iteration of the R5, it will probably only do 60p at 4k.  Canon will probably introduce 4k 120p at some point in the future but not this early in the cycle.  They are known to milk features at a snail’s pace in order to maximize the longevity of camera platforms.

    -8k 30p?  Someone is wishing too much, we possibly can expect if real the 8k to be a supersample mode to the 4k video in order to offer better per-pixel detail the way other camera brands do 4k by using a 6k source.   So we don’t expect 8k as a format to be anywhere in a camera from Canon this year, supersampling yes but full 8k no-go, especially in RAW mode, was it would require staggering data rates.

    If you want to see what 4k 120fps looks like, this RED Gemini 5K S35-shot video will give you a hint:

    Tomas Lemoine – Test Red Gemini 4K 120fps by JC Pieri:

    And if you have not seen 8k 30p video, let us point you to this amazing footage for a Samsung TV demo:

    Samsung QLED 8K 30P SDR HEVC 10bit Demo T5 posted byJmslhkq H:

    So at the end of the day we have imaging technology now that is capable of this and more but having it on a canon R5 camera for little cost compared to cameras that can do this seems for now out of the realm of possibility.

    In any case, we will know soon enough as CP+ will be at the end of the month Feb 27th to March 1st.  If Canon does show a new camera, we would love to be impressed but don’t count on it. -HSC

Sony a6400 Brings 120fps AF tracking to the Masses!

Sony a6400 slow motion

The newly announced Sony a6400 is what the a6300 should have been almost two years ago. It is still missing a key feature that was introduced with the a6500 that of IBIS or Sensor Stabilization which works with any lens added to the system. However, if you remove the IBIS fail from the equation this is a killer camera for just $900 which in this day and age of $1000+ cellphones, it is quite a bargain for the body only.

We were amazed by the 120fps full HD quality of other sony alpha cameras like the a9 and the a7 III which fully track subjects while recording in super slow motion which really makes the feature stand out compared to other cameras which force you to go manual while on that mode.  The codec quality has also been bumped in this camera for 120p to 100Mbps from 60Mbps on earlier cameras like the a6300 which should preserve more detail while sacrificing little in image crispness.

a6400 Main Features:

  • 24.2MP APS-C Exmor CMOS Sensor
  • BIONZ X Image Processor
  • Real-Time Eye AF & Real-Time Tracking
  • XGA Tru-Finder 2.36m-Dot OLED EVF
  • 3.0″ 921.6k-Dot 180° Tilting Touchscreen
  • Internal UHD 4K Video, S-Log3, and HLG
  • S&Q Motion in Full HD from 1-120 fps
  • Built-In Wi-Fi with NFC
  • 425 Phase- & Contrast-Detect AF Points
  • Up to 11 fps Shooting and ISO 102,400

a6400 Video Mode:

Format MPEG-4, H.264
Modes
  • 3840 x 2160 @ 30p / 100 Mbps, XAVC S, MP4, H.264, Linear PCM
  • 3840 x 2160 @ 30p / 60 Mbps, XAVC S, MP4, H.264, Linear PCM
  • 3840 x 2160 @ 24p / 100 Mbps, XAVC S, MP4, H.264, Linear PCM
  • 3840 x 2160 @ 24p / 60 Mbps, XAVC S, MP4, H.264, Linear PCM
  • 1920 x 1080 @ 120p / 100 Mbps, MOV, H.264, Linear PCM
  • 1920 x 1080 @ 120p / 60 Mbps, MOV, H.264, Linear PCM
  • 1920 x 1080 @ 60p / 25 Mbps, MOV, H.264, Linear PCM
  • 1920 x 1080 @ 60i / 24 Mbps, AVCHD, MTS, H.264, AAC
  • 1920 x 1080 @ 50i / 17 Mbps, AVCHD, MTS, H.264, AAC
  • 1920 x 1080 @ 30p / 16 Mbps, MOV, H.264, Linear PCM

Yes, 4k 60p is missing from this entry level camera but it still generates oversampling in 4k from its 25MP sensor and down converts to 4k UHD for a beautiful image with less noise and no perceptible moire/aliasing artifacts.

This a6400 camera is really crying to have IBIS in the sensor but with a small gimbal stabilizer, it should work wonders for their intended Vlogger audience.

NEW SONY a6400 CAMERA with a FLIP SCREEN by Jenna Ezarik:

The video above by Jenna Ezarik shows why IBIS is needed in a camera like this, it is quite shakey and the rolling shutter is apparent. The audio from the built-in microphones is very acceptable as is the video quality which rivals some of the best 4k out there.  Which means the higher-end model which is planned for the alpha line will probably have IBIS and even better features for under $2000 USD.
