That's the thing with all the fixes needed in video, they could all be implemented at nearly Zero expense, as they're all about coding decent firmware in the first place, or writing better code in firmware releases.

Focus Peaking on the LCD during Recording - Coding in the display library. (same goes with overlays for waveform, etc)
Return of true IBIS in Video - Copying the code from the K-5, or the code from IBIS in Live View Stills on every body, and pasting it in to the video libraries, over the MovieSR code.
Clean Feed Recordable HDMI - Altering the settings in the HDMI controller to output the same frame rate and format as it written to the SD card.
Upping the Data Rate to minimum 50mBits in HD video - Coding new parameters for the image processor to compress less (this one will actually reduce processing overhead.)

This is why the anti-video attitude of many on this forum makes no sense to me, same goes with the "It will make my camera more expensive" argument. It's bullshit, always has been.

The only way that's going to change, is for Pentax to be getting feedback asking for changes to video features, on every dang peice of social media and press release they do.
I got sick of feeling like I was the only one saying what needed to be changed, and getting shouted down by the Still Only crowd.
if we want improvements in the video side of the firmware, we all need to be vocal.

What's that saying? - "You don't know, what you don't know."

Now you know that you didn't know something, found out by testing and observation.

You are now a Scientist. :)


Sidestepping - the use of SD-XC cards by Pentax, is also one of the reasons the data rate for video doesn't make sense - it's set at 19 to 21 mBits for most Pentax bodies, and about 24 for the KP, but SD-XC cards and controllers can support much higher data rates - the original BMD Pocket Camera recorded HD footage, running the same sort of card and controllers at over 80 Mega Bits, the same year the K-01 was released.

There is absolutely no reason why Pentax couldn't have set the data rate much higher, and preserved the quality of the colour science - Higher Data Rate is Less Compression, so less work for the onboard image processor.

K-01 issue after taking a shot

When you turn the camera on, before pressing the shutter button at all, do you see an image on the screen, or only black?

If black, shutter potentially damaged.

If image, shutter is open (it should open when turned on, because, mirrorless :) ) and there something else going on.

Check in the menus,..
Page C-3, item 16, is that set to 1 or 2 ? If set to 1, it may not work with full manual lenses.
Page C-2, item 10, if set to Focus Priority, the shutter may not open when the button is pressed.
Page C-2, item 12, may stop it from opening if the flash hasn't recharged.

The numbers on the bottom of the screen will flash Red if you're below the correct exposure levels.

Most decent Non Linear Editing applications for editing video, also include well featured audio editing tools.

If you use Resolve, Edius, or even Premiere, you can load in audio plugins that offer extra tools, such as for audio noise reduction, Compressor/Expanders, equalisation, and much more.

Those tools are aimed specifically at providing good audio in a Video production.

Not Canon, not Nikon, not Pentax,.... The SD Card Consortium solved it.

SD - Fat 16.
SD-HC - Fat 32
SD-XC - ExFat.

If you use an SD-XC card in ANY camera, the only reason to have short files, is the EU Taxation, where a 'Stills' camera and a 'Video' camera get taxed differently.

Canon, like a lot of video camera manufacturers, use region Specific firmware on many models, so those sold outside of the EU will be ignoring the EU limitation.
The easy way to do that, while making sure the user can't loose a whole card's worth of recording, is to split the files, so the camera writes video from the sensor to a buffer, and the buffer is big enough to soak up any stops and starts at the card.

---------- Post added 07-05-20 at 10:50 PM ----------



I only use SD-XC, the Pentax's have had SD-XC controllers as far back as the K-01 / K-30 release, and they format to ExFat.

Neither of those have the same impact as the difference in the data rate in the CoDec.

The K-70 has the same 19Mbits rate as the rest of Pentax family (when set to maximum quality)
The KP got a data rate of 24Mbits, which directly affects the way the CoDec deals with signal noise, especially in higher ISO's.


At 3200 in most Pentax bodies, the noise that's "film like" in a still image, becomes a blotch of nasty colour around any noisy pixel in the image. But the extra data rate in the KP means it's colour blotching at 3200 is similar to that of the rest of the bodies at 800 or 1600.

In good lighting, it means that at lower ISO's, the colour in the KP's image is going to be a lot more accurate then the K-70.

With my Cinematographer hat on, out of all the currently available bodies, for recording internally, the KP is the ONLY body I would buy.

For external recording, none are currently suitable (and we've been providing feed back on that for the last Seven Years), but a firmware fix would make everything from K-01 to K-1 and 645Z in to awesome production tools.

Recordable HDMI output, preferably at 10 bit for HD and 4K, is pretty much "minumum acceptable specification" for any brand of DSLR or Mirrorless in 2019-2020. If the new prototype showing one Pentax stands now doesn't include it, they should go back to making film cameras for the luddites, as they don't understand the digital market.

The main difference between the DR-60D Mk2, and the DR-70D, is height - the 70 is half the height, but is wider.

The main difference between the Mk1 and Mk2 versions of the DR-60D, is the tactile response from the input level knobs - on the Mk1 they 'click' into postions, and on the Mk2 they're just regular knobs that turn to any position - customers hated the Mk1 knobs.

Both versions of the DR-60D, and the DR-70D, are all excellent recorders, with the DR-701D being the next step beyond for four channel recorders.

If you do video, the KP is a better choice - the K-70 has the same data rate in the CoDec as the K-01, so no improvement there, plus the KP sensor is significantly more sensitive - adding both together means the KP video remains colour noise (the blotching that occurs in the CoDec) free at higher ISO settings then any other Pentax - ISO 800 is the useful limit for the K-01 and K-70, with 1250 at a push (1600 & 3200 are useful only in an emergency content situation - news-worthy where they'd take phone footage,...)
The KP will do 1600 and 3200 relatively noise free.

Look from underneath, the battery is half the depth of the grip - Shifting the (useless) HDMI and the USB/AV over to the other side, as it is on most bodies, would have enabled a more slender grip.

Could make the argument that it's still in Beta - they never finished any support for the GPS unit for astro-photography use.

If I only had those skills dept,..., I would love to see the Pentax firmware cracked and decoded, just for the K-01, max out the Data rate for the H.264, an all i-frame option, an Mjpeg option, cut n paste the IBIS from the K-5 in to replace the MovieSR, and make it so when you plug in a screen to the HDMI, that camera stays in Record Modes, rather then switching to Playback only.



They'd be a very small bunch. There's many more people who love the K-01 for what's on the inside, because it is a good camera inside, the design is just un-ergonomical.

Marantz is an odd company - some of the stuff they made has a, almost deliberately cheap n cheerful look to it, while the circuitry inside is pretty much always well designed and low-noise, yet wonderfully simple, especially in the days of analog recording.

There are several brands of mixer that function the same as the PMD-602, I'd add the Beachtek products to the same list, just do make sure you don't use the right channel jack input, as the main output, like one camera Op I worked with in November did - I still don't know how we were getting any audio out of that set up :D

If you want the same sort of PreAmp layout to mount under a camera on the Tripod, the Tascam DR-70D is no taller then the Pre Amp's, but is a four input device, that can swap between external mics and it's own high quality mics.

I wouldn't want to run anything powered by the camera outside of Phantom Power, there's too much possibility of drawing more power then non-professional cameras can provide, and at this level, most will add signal noise to the sound.

The Rode Video Mic is a safe choice for most DSLR/MILC uses, is powered by it's own battery, and has decent shock mounting, removing noise from the operator handling the camera.

For lapels, starting out, the Rode Smart-Lav, which plugs in to and records to a phone, is also a good choice, and the sound files are easily re-synced later.

Marc Newson made it fugly, and Pentax screwed up the video features, which are x1000 more important to Mirrorless buyers then they are to traditional Pentax "I Only Take Photos!" buyers.

I own two. One for video, one for occasional stills.,

Stick to the K-5 - it has Sensor based IBIS, everything after had it disabled.
And it has the superior Mjpeg CoDec, which doesn't require anywhere near as much PC processing power to edit compared to h.264.

Both K-01 and K-5 have 32kHz audio, so you'll need an external audio recorder, like a Tascam or Zoom - the DR-70D is a good choice.

K-mount speedbooster to m43
Posted By PiDicus Rex
Replies: 8

Been there, done that, here's the issues.
First, there is no 'Speedbooster' for K-mount - "Speedbooster" is a Brand Name, for product by the company Metabones, and that company refuses to make products for K-mount lenses - I have an email from them from about 4 years back stating "We will never make products for Pentax lenses".

So, they do C/Y mount, with identical FFD, but won't do K,... as we say DownUnder, "Slack ****ers".
(I'm an Aussie, my language is Culturally Appropriate, look up the song "I may a ****, but I'm not a ****ing **** " by T.I.S.M. if you'd like to understand more.)

The brand name is also why StarTroop's search results varied.



Okie, so a "Focal Reducer", as invented waaaay back in the 1930's or '40's, for use in Astronomy,.. there are Kipon and other brands that do K to m4/3, and there's EF to m4/3 that you can use a K-to-EF ring adapter on. Or you can grab a cheap mechanical K-to-m4/3 adapter, remove the mount, and attach it to a generic EF-to-m4/3 focal reducer.

I've used these sorts of combo's to film on GH4, G7, G9 and AF-100 - all work great with Mechanical adapter and Focal Reducer adapter.
I also use them on a custom machines mount on my AJA Cion Cinema Camera.

Pentax K, KM, KA and M42 lenses can all be regarded as "able to resolve 4K".
P67 and P645 can be regarded as 8K capable.
Adding a Focal Reducer improves the sharpness on ALL of these Film Era lenses.


Here's where you'll likely run in to the same issues I have - Manufacturing Tolerances and Quality Control.

A lot of them aren't great, certainly not up to the standards needed for cinema use, and really require re-machining if you want precise FFD. My current focal reducer and EF ring combination is about 0.4mm longer then it should be, leading to lack of Infinity focus on wide angle lenses.

Which becomes a real P.I.T.A. if you want to shoot with camera on the shoulder and lens set to infinity while actors work at beyond Hyperfocal distance,... as they're out of focus when they should be sharp.

Don't forget, all Focal Reducers require you to adjust the Back Focus - the optical element can be screwed closer or further from the sensor, and then locked down with a grub screw.

K-1 II/K-3 II or Sony a6000 for basic "studio" work

Right now, for 2000euro and under, there's a lot of choice in the Camcorder market, with some of the current Sony's having a 1 inch sensor behind a fixed lens.
Panasonic has some good units too, and both those companies are well ahead of everyone else, though there a couple of semi-pro Canon's catching up too.

What your filming should determine what sort of camera gets bought - for Webseries, sports TV, sport live streams, adverts, films, drama, music videos,... that's what I pull my Cion out for.
For Behind-Scenes, I still reach for my K-01's, and the DA35 and DA40XS are perfect for that use, and I still pull the JVC HD7 camcorder out when there's enough light to hook up to my HDMI-to-RTSP boxes for live streams, and several HikVision security cameras for streaming Drag Racing etc,. and the GoPros when the space is tight, like putting a camera on the dashboard of my '66 Valiant.


The Cion has a similar size sensor to the K-01, so the framing and DoF is similar.

I'd still love a Sony VG-900E for music videos and behind-scenes, and a Canon XL-H1 or H1s for live streams needing to zoom in on the action.

But it's all about matching the camera to the right job.

There are several Cion owners across the EU, but I don't think we have one in Finland. Germany is probably the closest.
4000 Euro does open a lot of options, but it can actually be gotten for about half that, direct from the manufacturer, if you know the right person to ask :)
It's real advantage, is to shoot on the shoulder properly, and to expose the same as shooting on 35mm Film stock like the Kodak 250D or 500T, where the film stock has slightly less dynamic range then the Cion - 10 stops for film, 12 for Cion.
When used properly, the only camera that looks more like 'Shot on film' is the Arri Alexa.

It has none of the downsides of all DSLR/Mirrorless cameras, which all suffer from Rolling Shutter and bad ergonomics for video/cinema work, and are limited by the internal h264 CoDec, which sucks badly for cinema and high end advertising work.

Most of the decent intermediate CoDec's for video - DNxHD, GV HQX and ProRes, depending on compression profile, they can all exceed the data rate for Raw Stills for any current maximum burst rates, from any APSc or FF camera.
Some of the medium format bodies can still out perform them, 50 and 100 megapixel sensors will do that :D

The 12 bit Raw from my Cion, at DCI 4K and 24fps, will fill a Gigabyte in just under 5 minutes.

It's a return to internal storage,.. The limit there becomes transfering the media off the device, and the number of write cycles before the memory cells erode.

I just don't think it'll ever happen in any device aimed at Consumers or Prosumers. Maybe in something like a 645Z replacement, or, maybe have the M.2 drive slot in a battery grip, in the same way Panasonic added SDI output to the GH4.

More I think about it, SD or XQD/CFExpress in the body and M.2 in a Battery Grip would be pretty awesome, especially if you can unscrew the grip and use USBc / Thunderbolt to connect it to a PC.

Thing is, for Video, it'd be ideal, but then all the 'Stills Only' mob will whine about it existing, then claim it's 'only meant for stills use' when the finally adapt to Live View after Pentax gets to 30fps Electronic Shutter stills,....... :D

The 120fps DCI 4K requires a fast PC, AJA Kona4 Quad PCIe card, NVMe Raid Array and a stack of spare hard drives to offload to.

I feel your pain,... ;)

Reading through, all three cameras are okay, having the lighting is fabulous, but for what you're trying to do, the solutions are a little different.

First up, most actors, once lit, just do self-tapes with their phone and let their agent deal with it.

If the agent does want it recorded properly, the camera and lighting is far less important then clear sound, and all three cameras mentioned will do the job.

Grab a Rode Lav and record the sound to their phone, then in post just sync the sound to that of the camera. I've used multiples of these on location on web series and feature film productions, and they're more then adequate for 90% of production.

https://www.adorama.com/rdslplus.html?

If you get more gigs, then think about adding a directional mic on a boom stand - Rode NTG-2 is very widely used - and an good external recorder - I use a Tascam DR-70D,.. the Zoom H4n is a good choice, as is the Tascam DR-100, or the Zoom H1 stuck on the end of a boom arm.

SECONDED !!

Good choices for "My First Pentax Video Lens Kit" - any of the SMC M/K/KA 50mm's, f 1.2 thru f 2.0, the 24mm f2.8 or 28mm, the 85mm f 2 or 135mm f 2.8.

They will all give you more then 180 degrees barrel rotation, making focus a lot easier to hit manually.

If you've only got DA or D-FA, use AF to get the shot focused, then turn off AF and press record. :)

All the above are pretty good choices, I'd add the option of a secondhand SmallHD DP4, it's a little smaller and older, but can be optioned with an eye piece, so it can function as an EVF when the camera is on a shoulder rig.

One thing Steve missed - the Pentax implementation of HDMI, when you press record on the camera, it changes the frame rate and frame size on the HDMI output.
I found it out testing a mates K-3 with my Atomos Shogun, finding the output is virtually un-useable for external recording. It's also only in NTSC frame rates, even when the camera is recording to 24 or 25 fps.
