Pocket6k G2

Blackmagic Design surprisingly releases second set of pocket6k, is that a good thing?

And everyone talking about it … looking for flaws and reasons not to buy it, shooting it down … without having it in their hands …

Of course, I’m not going to sit on my hands and as usual, with my critical and defeatist style I’m going to list all the mistakes he made to make it a bestseller … undermining the sale of its own chambers….

Every camera manufacturer thinks about improving its products, and it is embarrassing how in Blackmagic Design they had the courage to improve their original camera by listening to user requests with :

  • sony battery like the pro
  • viewfinder compatibility
  • improved and bausculating monitor
  • New improved Os 7.9
  • Gyroscope recording to stabilize in post in a more modern way

Before, the battery seemed to be a problem, and now the battery is 3500 mAh, so one of the many “shortcomings” of the camera is gone.

Now instead of using external monitors you can use a very good viewfinder that is sold at a very honest price.

The bausculating monitor so one can complain that it is now not articulated….

About the new Os I talked about it the other day.

Of course many will think of it as a hybrid of the old 6k and pro, and the concept is right, they have taken the innovations of the pro, which is bulkier, and put the pluses in the box of the regular 6k, creating a scalar line of products for all needs:

  • pocket 4k the cheapest entry level 4k raw in the world
  • pocket 6k g2, 6k sensor, bauscular monitor, small footprint with many features.
  • pocket6k pro for those who need more audio inputs, internal ND filters, 1500 nits display.

for those who complain that they recently bought the “old pocket6k” well … the market goes on for all brands, indeed … many brands come out with a new model every year, while Blackmagic tends to bring out a new product or update every two years.

LUMIX DC-GH6 beautiful yes, but it is not FullFrame..

Panasonic recently released the new iteration of its flagships in the GHx series, the LUMIX DC-GH6.
I personally have owned several Gh2s, Gh3s, Gh5s, used with satisfaction for both photography and video and have always been more than happy with them, but… does a GHx still make sense in 2022?

So they want to convince us that this machine is good because it offers us only two or three functions, which more or less nobody cares about, but just to be fair … let’s see what the house dishes are :

  • Unlimited video recording (within the limits of battery life and support space)
  • Internal recording in Prores
  • Recording in 10bit 4:2:2 up to 60P at up to 5.7k
  • HFR and VFR recording at 10bit
  • Renewed v2 stabilized sensor

Trying to figure out if it’s worth it…

Unlimited video recording

As if it’s a plus, who cares that virtually all cameras or almost all cameras have a continuous recording limit because maybe the sensors overheat, the recording caches are small or because they are sold as cameras and not camcorders that are taxed more in Europe, so the limit is active in Europe and not in Australia, and for convenience of distributors, Europeans get this difficult. A Detail…

It’s a camera anyway, who cares about recording long videos with cameras?

Internal recording in Prores

And again, why waste so much space on the card (which to record in prores you have to use the new faster and more expensive cards) to use this ancient format, by now Prores is already more than 15 years old, when we can save space with a nice h265 (waiting for the 266 released in 2019)?

It’s a camera, it’s not like we can waste our time copying giant files, so who’s going to notice that they require less labor resources in computers, that they have fewer compression defects, more color accuracy, that we can postproduce them better…

Recording in 10bit 4:2:2 up to 60P up to 5.7k

Still pointing to these useless data recordings… do like others who record at 8bit, it’s 16 million colors, it’s always been enough, now it’s a numbers craze, if I make a video with a camera it’s because I don’t care to do color correction, waste space by recording in a non-standard format like 5.7k, no one has a 5.7k TV… maybe some imacs? and should I record for those few who have the 5k imac?

HFR and VFR recording at 10bit

And they insist on wasting space!!! Shooting at High Frame Rate (HFR) or Variable Frame Rate (VFR) at 10bit up to 300 frames per second, what’s the point of so much color fidelity, anyway already when you’re doing slow motion it’s cool, it’s not like you need to have accurate color … Surely panasonic aims to sell lots of expensive cards to fill with these features.

Revamped stabilized sensor v2

In a world where stabilized lenses have been around for thirty years still they point to the stabilized sensor, and they continue to improve it, making it easier to do the stable shots, and then .. move them in post, since now it is fashionable to blur the camera to give more “realism” to the shot … in fact it is since Cannibal Holocaust (1980) that they have been moving the camera in a rougher way to make a fiction product look more amateurish and real.

And we’ll stop here, because the other features have them too, nothing new in short, but it all serves to keep attention away from the biggest flaw, from that unacceptable original sin …

LUMIX DC-GH6 has it small, in fact the sensor is tiny, and all the videomakers and photographers cannot accept such things, it is almost offensive to propose a sensor of that size, you know well the limitations of certain things….

Are we sure?
Let’s start with a technical comparison, that is, let’s compare the size of the sensors starting with the mythological FullFrame, which is not big, in fact it has a very very large crop factor, as much as 2.4, but few people know that, I explain why in this other article by joking about it.

In this image we see how m4/3 is a tiny format for making video, and then if we compare it to fullframe there is no comparison… it’s obvious…smaller is only the sensors in the cameras that are surely amateur, if they have a 2/3-inch sensor or smaller still…maybe…or is that what the marketing would have you believe?

A few years ago a bearded engineer chose 2/3 inch cameras to make his new little film : Sony F23, Sony HDC-1500, Sony HDF-F950, chosen for their 2.2 million pixel sensor, which returned in HDCAM SR a 1080/24p image encoded in H264 base 6, 10 bit 4:2:2.

A compressed format-can you imagine?
a compressed format to even shoot a movie for the cinema!!!

After editing and post-producing his little film, he also had the courage to have it printed on film, both in 35m anamorphic and 70mm horizontal and Imax…
All from a sensor the size of a cat’s spit!!!

As an experienced engineer in the field, he knew that he was pushing those sensors to the limits, and although he could get FullFrames, the beautiful 5dMkIIs were available, he flatly refused, he was a bonehead and wanted to use the cameras even though they had that incredible handicap…

Rest assured that after that waste of energy and money, few went to the movies to see that little film, in fact to date he has earned

only $2.84 BILLION!!!

Avatar is still the highest grossing film in the history of cinema….

Think what it would have earned if it had shot in fullframe with a good camera?

I got the technical shooting information from the excellent IMDB.com site that has always been the reference for filmmaking, for which I cannot thank enough a friend, Giancarlo Cairella, one of the founding members.


I always like to mess around with new products, with ridiculous myths, both because if I took marketing and fan boys seriously, I would put them both to the stocks, and because although I am on the threshold of half a century, I like to approach life with the eyes of a child 😀

But let’s open our eyes to what is often just marketing, and quality, capability is far beyond sensor size and many other hissy fits, and try to understand what features really matter for the work we have to do.

Panasonic Lumix GH3 a camera for VideoMakers

After using its little sister the Lumix GH2 for two years, I tested Panasonic’s newest addition, the Lumix GH3, a digital camera hidden in the body of a mirrorless…

Since the birth of the Nikon d90, which made 1280 x 720 movies, filmmakers had realized that so much would change… Canon cleared the concept of shooting with HDSLRs, and Panasonic has learned many things, from the mistakes and shortcomings of the competition…

What does the new Lumix GH3 offer the filmmaker?

The camera was born with features geared toward professional shooting. After an almost muddled start with the GH2, Panasonic has adjusted its focus by optimizing the video compartment of the new camera.

  • Three different ways of handling video, encoding it in Mjpeg, Avchd and finally in MOV container with frame rates varying from 60 to 24 depending on shooting settings, all in FULLHD.
  • Native mov I-frame quality at both 50 and 72 mbits outstanding, no need currently to Hack (see GH2 with Flowmotion and the like) to extrapolate from the sensor the extraordinary quality of this machine. (Maybe for a raw…)
  • Robust and clean codec, no blocking or other junk in the shadows.
  • Slowmotion mode allows 24p footage shot at 60P so a true 40% slowmotion in fullHD in-camera.
  • Time code video running free or can be set manually
  • CLEAN 4:2:2 8 bit HDMI output for external video recording without moires shadow (slightly present in HighFreq recordings).
  • Zoom with 1:1 pixels for lumix lenses or manual focus that also works with external monitor connected via HDMI (which the GH2 did not)
  • Headphone output that can be used to monitor recorded audio (rec sound mode) or to externally record audio (realtime, pass-through mode without audio compression).
  • 3.5mm microphone input with internal adjustment of as many as 19 audio levels, a remote input for remote control.
  • Wi-fi connection with app for Iphone, Ipad, Android for remote control, remote viewing and more.
  • New bright and adjustable Oled monitor for shooting in complex conditions and angles.
  • Built-in Timer for creating Timelapses without the need for external products.
  • Good light and shadow sensitivity, with native sensitivity of 200 iso.
  • Full sensor utilization and format reduction to FULLHD using pixelbinning technique eliminating problems such as aliasing of cameras using line skipping.
  • On monitor you can view audio levels, grids, gyroscope that helps you see if the camera is on bubble, exposure histogram, Overexposure Indicators, and much more…
  • Heavy and sturdy body, tropicalized, battery pack provided with contacts below the camera (unfortunately with only one battery, but I await a battery pack compatible with multiple batteries).
  • Battery lasting me almost three hours in video, record-breaking (unstabilized manual lenses).
  • The body has several customizable buttons that allow us to optimize the use of the camera according to personal work habits and choices.
  • Zoom window system for touch focus control swivels on the LCD.
  • Much higher sensitivity for low light shooting with image setting adjustments to balance the ratio of noise reduction to final image quality.
  • Sensor scan optimization that features less rolling shutter than the gh2
  • Much faster autofocus than the GH2, and controllable (like GH2) via touch LCD by touching the element that needs to remain in focus.
  • Higher sensitivity and cleaner at high iso than gh2 without losing definition, you can use up to 1600iso without particular loss.
  • WI-Fi module gives the ability to download photos immediately after shooting, which would normally be of little use, but makes it more convenient to use gh3 for software-managed stopmotion.
  • Standard in-camera TimeLapse function and preview as a movie directly IN CAMERA.
  • Larger overall dynamic range and very close to a competitor costing twice the price (see below Dpreview’s dynamic range test between the MkIII and GH3), although all the MkIII admirers say there are monstrous differences between their camera and the others…but have they ever tested them systematically, and verified them instrumentally?
MkIII vs GH3

What’s not to like?

  • Iso 200 minimum in video, no way to emulate a lower iso…which means that in most outdoor shooting I have to be well equipped with neutral filters, because the minimum sensitivity is very very high.
    I would have liked some form of iso downsampling, such as the extended isos that are in the photo compartment for video as well, hopefully good Vitality can get a handle on that…
  • The different color presets differ little in tonal range, I expected more, used to the GH2 where the different profiles have different working ranges, but the richness offered is already very good.
  • With the 20mm 1.7 Lumix occasionally has focus uncertainties that I do not encounter with the 14-42 powerX. Panasonic will release a firmware update and fix it, as with the 12-35 which has already been updated.
  • Some setup items are present only in the photo menus and not in the video one from list, but they reappear in the quickmenu, for example if I want to disable the stabilizer, I have the menu item in the photo compartment, while in the video one I don’t, to disable it I have to go to photo mode, disable it and go back to video… but nothing that a firmware update can’t fix, however it is tedious.
  • The focus peak is missing, which had been talked about (video interview of a panasonic engineer),but mysteriously not present, on the gh3, however on the GF6 it is present as a feature…will it appear with an upcoming firmware?
  • It is inconceivable that you cannot set shutter and iris differently between photo and video departments.
  • In preview before pressing REC there is still a difference in quality (less than recorded) in the preview monitor as in the GH2. It is not understandable why–if the camera in recording (thus at maximum processor load) can have the preview correct as quality, why can’t it when there is no active recording?
  • the lumix app provides for starting recording remotely via WI-fi, but from that point on the machine is blind, so you can’t turn off recording and the video stream no longer arrives via wi-fi, so it’s basically good for a cell phone self-timer and little more.
  • the Lumix app provides for once connected to the camera to transfer only jpeg photos to the phone or tablet, there are no on-the-fly raw to jpeg conversion systems for transfer.
  • there is (to date) no SDK to develop support for wi-fi or USB connection, so you cannot hook external remote software (StopMotion, special timelapse, Motion Control, etc) to the camera.
    And/or one cannot develop waterproof housings for underwater filming with remote control, but one must be able to mechanically operate the buttons, which raises the cost of the housing and increases the risk of infiltration
  • The battery pack contains only one additional battery even though there was room for two batteries.

Moires on the GH3

On the net there is talk of moires on the GH3 and not on the GH2, yes, there is moires on the camera, particularly using Lumix lenses it is highlighted more, but we are talking about small things, that is when we go to shoot at very closed apertures images with high frequency detail, so very very fine.

To test the moires you can see what I did below, a movie (to be seen in the original fullHD) where the footage shot was thrown in sequence on an aftereffects timeline and scrolled with contrast and sharpness values from one extreme to the other without seeing any particular differences on the slight moires of the camera.

If you want to download the original file, you can do so from here, also because to judge the video file it must be viewed in FULLHD without going through Youtube compression.

I work with footage from different DSLRs, often with other brands I am used to seeing the “wriggling snakes” and “swarms of flies” on high frequency details.
Seeing these kinds of artifacts on the GH3 images for me is like saying that moires are nonexistent, especially because in practice then I didn’t find them on the movies, because you have to find that exact combination of frequency, camera distance and focus…

Curiosity:

The HDMI output is free of moires, so it occurs to me that it arises in the video compression, probably a future hack, or a slight variation on the bitrate by panasonic, or on the compression tables could eliminate the problem completely.

Conclusions:

A great camera for shooting video, for photography it is equal to the gh2, it suffers (theoretically) from an 8 bit raw, and a poor raw latitude when compared to the entrylevels of nikon and canon where for half the price they offer 12 and 14 bit raw, but you can’t have everything, I bought it to shoot not for photography, though still… it does well in that department as well.

Final notes: this quick review (there are many and more extensive ones, the best can be found on Dpreview, of the true DSLR review pros) is a series of practical and pragmatic observations from a videomaker, little talk and lots of substance. It will always be in working in progress, because as I use the camera I will update the review and be able to say more about this amazing working tool. Maybe in a month or so I can complete it and accompany it with a minimal reel of images shot all with the GH3, in light and shadow, day and night 😀

Update: I have posted a brief review of the photographic part of the Lumix GH3 here
