James Wages: Depth-to-Defocus (DtD) is marketing hype trickery for those of us who use the GH5 and know that Olympus PRO lenses, which are sadly incompatible with DtD, are superior to Panasonic’s lenses, by and large. Only Panasonic lenses are currently compatible with DtD, which is limiting and ridiculous. Hence the strong demand among GH5 users for phase detect AF that works with any lens. If Panasonic wants us, valued users who keep their business alive, to support them and their efforts to improve AF, Panasonic should freely DtD technical details to any u4:3 lens maker so most lenses can become compatible with it.

I have used some Panasonic and Olympus lenses with my GH5 and there are some Olympus lenses clearly better in image quality over Panasonic variants.

Some lenses I have found are the Olympus 12-40 f/2.8, which I have seen is sharper corner to corner than the Panasonic 12-35 which I found had slightly soft corners, especially at 12mm, where the 12-40 doesn't have as soft corners and is overall sharper and it has a manual clutch focus as well as being able to focus closer than the 12-35, even if it does lack IS.

I also found the Olympus 40-150mm f/2.8 PRO to be overall sharper than the Panasonic 35-100 f/2.8 especially around 70mm with better corner sharpness. Saying that I still like Panasonic lenses like the 20mm f/1.7 II which I find has good sharpness, even at f/1.7 and excellent at f/2.8 and I think the Leica 45mm Macro could be slightly sharper than the Olympus 60mm Macro, but I prefer the Olympus as its a longer lens which is better for macro shots.

kevin_r: Interesting how a stills camera is being morphed into a video camera. Why not simply go and buy a complete video camera to do the job? Why hang around these things hoping they'll give all the functionality of a video camera and then want to so,so occasionally take some stills? Don't talk about price since people are demanding the actual real functionality available in the video cams - but want to pay nothing for it. Go figure.

Mystic38: Not at this price with interchangeable lenses.Yes the GH5s lacks the ergonomics of cine/camcorders but i most other ways it is better

With the GH5s, you get 4K 10-bit 4:2:2 60 output, 4K 400Mbps ALL-I 10-bit 4:2:2 internal with LOG and 10-bit Hybrid Log Gamma, up to 240fps 1080p, the low light ability to name some great features, and a sensor of 4/3 or bigger with a similar or better video quality and your not limited to a fixed lens so can use any lens you like and have the quality and focal lengths you need.

(unknown member): Another congratulations to Panasonic. Now let’s move on and put this camera in to a different body next time. Something with shape and ergonomics of a C100 for example? Add proper audio inputs, price it below $3K and rule the world.

mosc, Olympus said last year that they are working on 8K video for M4/3 so it must be possible if Panasonic are now saying they are working on it, but it does beg the question of how much diffraction you'd get with that many MP needed in a 4:3 sensor and how the small pixels effects low light performance too.

Personally I think it would have been better if they did what JVC did with LS300 and gave us a Super 35mm sensor with an M4/3 mount, that should solve the smaller pixels issue and low light hit, but there is still Panasonic's organic sensor, if that ever comes to a M4/3 camera...

Richard Murdey: Seems odd to remove stabilization, since the assembly was already baked into the GH5 and anyone who didn't want to use it (when on dollies etc.) could just turn it off. Either they needed the space to put the larger sensor in there, or removing it allowed better heat management during video recording. Both of which are totally valid reasons to drop the feature, but the "oh, we did it 'cuz _pros_ don't need it anyway" explanation represents everything about marketing I dislike.

Likewise I'm all for using a slightly oversized sensor to get the most out of different crop formats, but, "this also means that the diagonal angle of view is preserved" has no practical photographic merit in itself and should not be touted as a feature.

Wex Photo Video made a video on the GH5s here: https://www.youtube.com/watch?v=-TvczoXB1aA

They posted a comment about the IBIS:

"Hey, some more info for you on that point...We found out (after shooting this video) that to make this a multi-aspect ratio sensor that it needed to be ever so slightly bigger than the sensor in the GH5. This meant that the GH5S' sensor wouldn't fit the IBIS housing that was used in the GH5. Thanks for watching - KH"

I like that the Arri has much more dynamic range, but from this, the both camera shots don't look great to my eye using a color calibrated monitor. The 80D has that magenta color shift that Canon is known for, which I am not a fan of, whereas the Arri footage looks green.

If the Canon didn't have that magenta color, I'd like it more as its colors do seem more pleasing than the Arri, even if it doesn't have the amount of dynamic range the Arri has,, but the 80D produces soft 1080p which doesn't look great.

GreatOceanSoftware: Please stop making spinning hard drives. Just stop.

@GreatOceanSoftware I'd rather have a spinning HDD than an SSD at times. Yes SSDs are faster, and would be great for editing photos and videos and booting from, but I have currently been a bit reluctant to use them for backup and storage, especially as I shoot a lot of videos, raw photos and sound recordings and need to store and back up to 100GB+ of new files at a time and surely writing that amount of data often to an SSD would wear it out faster than a HDD?

I have had an external 100GB HDD since 2005 that has never crashed or had problems and I have used it quite a bit (of course I have backed it up many times so if it does fail I'll still have the data) could the same be said for modern SSDs currently? I know you are at risk of crashes and other problems with HDDS due to moving parts.

I guess there will always be something more powerful than what we have.

@bwana4swahili why? I have used external Seagate drives for years with no problems at all

Looking forward to the update, especially the hybrid log gamma as I take all my videos on my GH5 in V-Log L and HLG looks like it will be a better option for me. Now I'll just have to find a V90 memory card.

I am hoping the focusing will be better, but being contrast based, I can't see a huge improvement in the auto focus.

Why keep XQD? Since there won't be anymore Lexar QXD cards, Sony is currently the only one who still makes them, so it would be better to move to a format more wildly available like USH-II SD cards which can be found easily.

I quite like the spider shots, the lizard and the cool looking eyes of the hoverfly (I have always liked the markings of flies like hoverflies, even if I get bitten by hoverflies quite often! in the summer!), but the cockroach in 10 is practically out of focus as is most of the bess beetle in 5. Really those two needed much more DOF to be useful as unless you only want a very small area in focus for a reason, with macro you'd really want to have much more in focus than that.

KerryBE: So what makes a cinema lens so special?

Aren't cinema lenses supposed to not suffer from issues with chromatic aberration and distortion? (unless its meant to have distortion like a fisheye lens) Many photography lenses do and when editing photos you can correct issues like this but its harder to do that when your editing videos, especially chromatic aberrations.

On article Why would I want an external recorder/monitor? (68 comments in total)
In reply to:

Foxy2012: External recorders are excellent! This is if you can afford it after your camera and lenses, however, consider renting one for important gigs. Additional benefits include extended recording time (beyond 29:59 minutes), helps with overheating on some pesky cameras (i.e a6300) and improved audio (some recorders have xlr which is great). I like the bigger screen which makes focusing and composing much easier.

Downsides: heavy, awkward weight if you factor in the recorder's batteries, Fiddly connectors if using hdmi and expensive accessories such as recording drives.

Another benefit is you can quickly transfer your recording directly into your NLE and immediately begin to edit (file is already in your editing codec -- no transcoding). Files can quickly get large, though -- plan your backup workflow.

I agree with you on all points. Some I'd add:

Bigger screen so better to judge focus with focus peaking than a smaller screen of the camera itself (especially the GH5 only has focus peaking in manual focus only, not good since the auto focus doesn't work well enough to not need peaking to show the camera has locked on focus),

Many recorders now have HDR screens with high brightness, great for shooting log or RAW (if your camera supports either).

Better codecs of ProRes and DNxHD/DNxHR - No chance of macroblocking you get with AVC H.264 and H.265 codecs, and higher bitrates on external recorders.

You can use larger capacity SSDs than you can with SD cards so no need to keep a lot of SD cards with you, just one or more SSDs and enough batteries and you can shoot all day if you need to, Downside is the larger file sizes you have to work with.

Some cameras have not only better color subsmpling and more color bits, but also better dynamic range when shooting externally.

On article How do you know you need a new camera? (402 comments in total)

Late last year I made a decision that I wanted to get more serious about taking photos and videos. My current camera was a Panasonic GH4. had been using it since Jan 2016 and I had quite liked it, but always felt like it was limiting me in some ways.

I found out about the GH5 and was interested from reading the specs. I started saving for a GH5 in December and didn't know if I would get it or just keep using my GH4

By waiting for the the GH5 and continuing to use my GH4 and having the time to read more about the GH5 and what it could potentially do for me that the GH4 couldn't, I was able to come to my decision.

I now have a GH5 and since April I have shot over 700 photos with and at least 2 hours of usable video and this is because the GH5 has features that have really helped solve many of my issues I had with the GH4.

Since the GH5 solves all my camera needs for now, unless I move to ASP-C, FF or dedicated video camera, I don't see myself upgrading for a long time to come.

No one "needs" 8K, and as nice as this 8K monitor is, its still very early so this lacks the features of high end 4K monitors like HDR, Rec 2020 and refresh rates higher than 60hz and you need top end graphics cards to run it. Right now I think its better to hold off until the technology catches up before thinking on getting a 8K monitor, but I can see the benefits, especially when you are editing high megapixel images.

If I had a lot of money to spend and I was looking to get a high end monitor right now, I'd rather look at high end 4K monitor like the EIZO ColorEdge PROMINENCE CG3145 4K with 99% Adobe RGB, 100% sRGB, REC709, REC 2020, HLG REC2020 HLG,DCI, PQ REC2020, PQ REC709 etc... and wait until graphics cards and 8K monitors get better and support the features many 4K monitors now have that this 8K doesn't and by then, when there are more 8K monitors on the market, the price will probably have come down a bit too.

Brother Younger: This is important enough for anybody interested in or using GH5.

Panasonic is planning to add 400mbps ALL-I video encoding for GH5 this summer, but that does not raise the bar of image quality for the videos recorded by the camera as ALL-I has much higher requirements for the bitrate (compared to IPB) for an equivalent image quality. I've created a petition for Panasonic to add support for high bitrate IPB modes into GH5.

If you like that idea, please sign the petition: https://www.change.org/p/panasonic-introduce-4k-4-2-2-ipb-400mbps-and-fhd-4-2-2-ipb-200mbps-modes-for-panasonic-gh5?recruiter=44141647&utm_source=share_petition&utm_medium=copylink

I didn't realise that until I looked it up. It seems that ALL-I the only benefit I can see is would be that its easier to edit with. I signed but I don't know how much good it will do or not. This interview Joseph did with a Panasonic rep back in February mentioned the codec, but he never said that ALL-I will give better image quality, just much larger files and better to edit with: https://www.youtube.com/watch?v=51CDeENsmpQ&list=PLRe8DcOhgsloChzSSPPOkHDPCrUoffqKc&index=2

maxnimo: If you're doing 4K filming, you only need 8MP of resolution, so a cine lens need not be nearly as sharp as a 50MP photo lens. So why such ridiculous prices?

Some lenses though do have to be sharper than 8MP, 8.3MP resolution actually. That resolution is just the resolution of the video itself. Often today, many cameras have higher than 8MP sensors and when you record in 4K with those, they will take the extra pixels and downsample them to 4K, meaning the video will look better than if you just had 8.3MP and no more, meaning a lens rated higher than 8MP on those cameras, will look sharper than a lens rated at exactly 8.3MP

You could just use a photo lens, as Dheorl said, there is more than just sharpness. There is things like being able to do smooth and consistent focus pulls which you can't always easily do with photo lenses, smooth trans focus zooms, high light transmission from the lens to the sensor, consistent aperture throughout the focal range on zooms, good colour and contrast, smooth bokeh etc... no noticeable issues with CA, distortion, coma, vignetting etc... High build quality is important to.

"A problem in which afterimages appeared when recording video under high ISO sensitivity settings in using [V-LogL]" - While they are addressing that for V-Log l (I don't shoot at high ISOs, especially with V-Log L so never experienced this issue), I really wish they would fix the pink banding you get (I have only noticed it in cloudy skies)i with V-Log L.

I shoot in 10-bit 4:2:2 and you get noticeable pink posterisation issue with clouds with V-Log and pink around bright highlights in skies sometimes. I had similar issue with V-Log L on my GH4 shooting to an Atomos Ninja 2 recorder at 10-bit, so its not the codec on the GH5 that was causing it.

brownie112: Does it use h264 or h265 for recording?

@VisualFX A Panasonic rep said they didn't add H.265 because most editors didn't support it and its much harder and slower to edit with at the moment than H.264, but then again their 10-bit 4:2:2 LongGOP files are not quite easy to edit with at the moment either.

vFunct: Eventually a camera manufacturer will come out with a camera that shoots the entire frame in Raw at 240fps, and we won't have to deal with this 4:2:2/vLog nonsense.

I'd rather first have RAW output via HDMI as current external recorders can record RAW, which makes more sense than RAW 240fps right now.
