Those are such a minority request. No camera these days is going to sell in numbers that have a financial return greater then the development cost if it doesn't have video and an LCD.

Monochrome is a stupid waste of resources, the Bayer Filter decoding can be switched off in software and a per-pixel biasing to account for the colour filter over the pixels applied to correct lumanance channel data. Doing it in hardware is stupid when it can be done in software and then everyone can enjoy it.

Classic Controls, yes, because we should be able to tell by feel where our settings are, and change them on the fly.

AF is for people that don't buy K/KM/KA glass :D

NEVER shoot a screen unless you're doing so with a Broadcast camera capable of syncing itself to the screens scan rate.

The Elgato option is good, J-5Create also do a USB based grabber that performs well.

So, having done wedding videos professionally, your BEST option, stick to Stills.

Out of the two cameras listed, and as a Song VG-900E owner (y'know, the Only Full Frame Camcoder ever made) and TV Broadcast Camera Operator, for most people, the colours of the Panasonic will look more natural, and closer to your Pentax's colours. The Panasonic will also take less time to learn, and do okay in full auto.

And all that said, if I was ever to allow myself to be sucked back in to do a friends wedding, I'd pull out my pair of K-01's, fast wide manual lenses, and some decent tripods - avoid shooting hand held for this, tripod or gimbal only.

Video noise reduction options?

Was this to get rid of the crosshatch pattern 'noise' in the night time footage?
If so, Resolve might not help there, as the de-noise options are for high-bitrate footage CoDecs and Raw - where you can see the noise individual pixels in the frames, and not the cross hatch blur that forms around them as the data rate drops.
You 'may' be able to get decent results with unsharp masks, or transcoding to cine level CoDecs and then applying a blur to even out the pattern in large solid colour areas of the frames.

Best option is External Recorder.

@Mooncatt - Watching your shadow in the first video - you're doing this Hand Held? Elbows in to the side of the ribs get more stability, combined with the right-hand-grip, left-hand-under-lens.

But if you really want to pick up the quality, a fast wide Manual lens, and a Zhiyun Crane gimbal are a big help with Drag Racing - forget zooming to the finish, it's a waste, and with the wide set to Infinity and wide open, the subject matter is out past the HyperFocal Distance of the lens, so everything in frame is acceptably sharp.


Speaking of the finishes,... you NEVER want to be at that end of the track when filming. I can not stress this enough - Do Not Ever stand near the wall at the finish line !

If a driver crashes, anyone near the wall down there is in deadly danger - cars come over walls, or through them, if the speeds are high enough.


Standing up in the grandstand with a long lens is wiser.


I put security type IP dome cameras on the walls when doing streams specifically so I do not have a crew member near the wall at the fast end.

Back to the tech - what folks see as noise in the low light sections, isn't noise, it's the compression artifacts, which is why when shooting nights with the vast majority of DSLR/MILC, one should use an external recorder and a codec like DNxHD or ProRes.
(And with that we're back to Pentax not doing true Clean Feed HDMI,...)

What frustrations have you faced trying to video with your Pentax DSLR?
Posted By PiDicus Rex

K-5 was the last body with IBIS up until the K-3iii - MovieSR should be deactivated on every camera that has it.
Every time someone from Pentax was asked about adjusting the firmware to bring back the sensor-shifting IBIS, they said it wasn't possible, however, if you put all the bodies from K-01/K-30 thru to K-1 in to Stills, mirror lock up live view, with the true IBIS turned on all the time in the settings, the rear screen displayed video with true IBIS.
It was ALWAYS there in the body, they just would not activate it in Video.

So to the OP's question, one of my two biggest frustrations, was how much the disregard the companies marketing and management has had for the video functionality, and the second biggest being how large swaths of the Pentaxian community dismissively treats anyone who does video with Pentax bodies - the latter is why I rarely post here any more.

Which non-Pentax DSLR body to use my Pentax lens for video?
Posted By PiDicus Rex
Replies: 16

Panasonic GH 4 &5

Sony A7s, a6200, NEX VG-900E
Blackmagic Cine Camera, Production camera, Original Pocket Camera.
AJA Cion

These are some of the camera's I've had Pentax lenses in front of.

K/KM/KA are just sharp enough to take the harsh edge off a lot of modern Cinema cameras.

FA* are sharp enough to look like high end cine lenses, while DFA* look better then most Cine glass.

Straight thru mechanical adapters are everywhere, Focal Reducer type adapters can be an issue, as a couple of the manufacturers of those will not make K-mount versions, even if they already make Contax-Yashica versions with the exact same Flange Focal Distance. Usually they make a focal reducer for EF lenses, they work okay, but I've found a lot can be just a little loose - a layer of Mylar tape with Evaporated Metal on the non-sticky side can be put over the adapter to take up that looseness on the lens side, with the metal making the same contact across the lenses electrical contacts the way using it on an old film body would.


Avoid trying K-mount glass on Full Frame Canon DSLR's, the mirror will slam in to the aperture lever guard, and then the lens becomes very hard to get off the EF bodies.

G-85, G-9 are a cheaper way to get decent video out of Pentax glass.

If the rolling shutter wobbles are an issue (they really shouldn't be on a Pentax body unless you're really swinging the camera about), there are a few Global Shutter bodies, but be aware they have a lower sensitivity to light.

Rolling shutter wobbles are made worse if you have the Stabilisation "on", for everything between the K-5 and the K-3-3. Turing it off and using a gimbal is a better choice.

At the opposite end of the light handling, the A7S is about the same MP as a K-5/K-01 era body, but FF sensor size, and with the faster 35, 50 and 80mm Pentax lenses you can take video and stills wide open using only one or two candles for illumination.

Pentax Limited on anamorphic adapter.

Reviewer is a bit of an idiot - stacking Anamorphics is daft, just causes a loss in resolution and multiple overlapped bokeh distortions. Might as well use a reflector lens for fashion photography.


52mm thread isn't the issue the reviewer makes it out to be, as you'd be using it on Manual Focus lenses anyway, K/KM/KA full frame lenses that suit are mostly 49mm front, from 24f2.8 through 50f2/1.7/1.4/1.2 and out to 135f2.8 or 200f4.

"At least in my opinion, you should be very careful using anamorphic adapters with old lenses, because you can end up with some very soft imagery depending on the lens."

What a moron,... that's WHY we use them, to take the harshness off that modern lenses have.

For someone with his claimed experience, Allard is a bit crap at reviews of things he doesn't understand.

Looking at the samples on Blazar's youtube, I might get one, it'd go well on my K lenses in front of my Pentax's, VG900 or Cion.

For vertical video, use a phone. As much for the direction of the rolling shutter across the sensor, as for the social media nature of vertical video.

To rotate your video without command line headaches, download the free version of DaVinci Resolve, create a social media acceptable project, load video in to timeline, click to Colours tab, use options to rotate video, export.

And that reminds me, I have to un-bury Dad's hit n miss motor, and set it up with an alternator, to augment the solar panels.

Looking for advise on video for wedding speeches
Posted By PiDicus Rex
Replies: 10

As someone who used to shoot wedding videos professionally, the single best peice of advise I can give you is,...


RUN !!!


Run now, as fast as you can, away from that industry!!!



Now that's out of the way, there's no Pentax body that shoots video that will overheat under normal conditions - I have seen the temperature warning once, and once only, on any of my Pentax bodies, and that was a K-01, standing in in direct sunlight, on a cloudless 40+ degree C day in Melbourne, after it had been recording for long enough to fill half of a 32Gb SD card.

Use two cameras, start one recording 5 or more minutes before the other, so that the recordings overlap, rather then having the 20-ish minute record limit leave you with nothing recording at the same time - put the second camera slightly off to the side on a tripod with a longer lens, it'll give you a nice cut-away in the edit.


With Manual lenses, a K-01, K-5, K-3 etc should get about Four Hours of record time per battery. AF lenses you can halve or quarter that time.


Use and external recorder - I will always recommend the Tascam DR-70D for this purpose. Paired with a Rode NTG-2 in to one channel, and some Rode Go's in to two channels - you can easily hide the Go in the Lapels of a Grooms jacket, or use them with a Lavalier mic and pop the transmitter in a pocket. The Go can also clip to the same podium etc the speeches are made from, or be used to relay the sound from the DJ's mic at the reception, or the priests mic if they use one (many now will)

Put that recorder on the camera that stays on a tripod, not one on a gimbal or hand-held. Use the uninterupted audio recording to sync the video in editing.

Lighting, done right, adds dramatic atmosphere, such as a well controlled spotlight with just enough diffusion to soften it - barn doors to shade everyone else, keep the light on the couple, but on them it MUST be soft.
Light bounced of the walls and filling the room, that's what kills mood and atmosphere.
Co-ordinate with DJ/Band etc for smoke and dry-ice effects during reception for dances.

Quoting Clackers

"That's just for JPGs, right? Don't think either apply for RAW or video."

Colour filters for Jpegs affect Video. Use Muted, you can tweak from there once practiced, and you can pull a couple of stops out of the highlights in Edius or Resolve.

Highlight and Shadow Correction, they do have an effect, you'll notice it most when grading.

Now, all that said. RUN!!!

At best, hire in a subcontractor that specializes in the video production, at worst, do it on a decent Samsung phone, S20 Ultra is a good choice, especially with the recent camera software updates.

If you can, and for HD only, buy a Sony VG-30 or VG-900 and get a Monster Adaptor for your Pentax lenses, they're the Only camcorders with S35 or FF sensor that will have the Bokeh to match your photos, every other Video Production Camera that will do so, is out of the price range of most people - BMD Ursa Mini G2 for example. And being Camcorders they don't have record limits.

Have you started running away yet?

Is CCD sensors are still good ?
Posted By PiDicus Rex
Replies: 13

Searched CCD after watching a Snappiness video, and came across this thread in the results, read through and decided to correct one inaccuracy.




And, Nooooope.
CMOS replace CCD for one single reason, CMOS is SUBSTANTIALLY cheaper to manufacture.


Exactly the same reason why Rolling Shutter replaced Global Shutter on many cameras.

And in fact, at the time of the first CMOS sensors, about 8 to 10 years before the first one appeared for Stills cameras, CMOS sensors were universally hated for TV and Film production because they were very noisy. Mostly they still are, but the colour science inside the bodies has gotten better able to reduce that noise without loosing detail - look up Panasonic 3D noise reduction for some side note sillyness.

Today, very few cameras have either CCD or Global Shutter because manufacturers like profit more then customers like paying for quality. The greater ISO now available came well after the impacts of money.

Oh, that's right, most folks shoot Autofocus,... where the K-01 has focus peaking and I has a collection of manual only lenses,... :D

I also have the practice of doing broadcast TV with focus peaking on manual ENG lenses.
I swear, my AF glass lives on my K-5's, they'd be the only cameras I use for Stills that I used AF on - I've got AF on my Canon XL-H1, and my Sony VG-900E, but the K-01's, IstD*, MZ-50, P30n and P30 and AJA Cion, it's MF all the way.

Well, for Pentaxians, absolutely! But don't forget, Canon and Nikon's DSLR offerings were much heavier on average, and their MILC models are closer to Pentax DSLR in mass, with Sony and Panasonic able to make lighter models.

Frankly, as someone who's used to putting 12+ Kilograms of Cine camera on my shoulder, the "DSLR so heavy" looks and sounds silly. Heck, a 645D is lightweight and easy to use compared to most Cine cameras when used handheld, and Cine bodies like Blackmagic Designs originals and Pocket Cameras used held out like a K-01, will tire the spindly little 'Stills!' shooters arms out faster then they would believe. :)

---------- Post added 12-12-22 at 04:54 PM ----------



Yeah, I can, come try my Cine camera, which is half the mass of an Alexa and 2/3rds the mass of a Red. Trust me on this, a Pentax APSc or FF DSLR is NOT heavy.

---------- Post added 12-12-22 at 05:00 PM ----------



You may have a solid point Norm. I'm a couple of decades younger then you, and some of the under '30's working on some of the same broadcast TV gigs seem unable to carry an ENG camera up several flights of ladder-like stairs in to a camera tower at sports arenas. They look at me doing laps with the camera in it's roadcase, then the second case with the lens and focus/zoom demands, and the matching tripod head, and I can see them going goggle eyed.

But, y'know, old camera ops / cinematographers / directors never retire, we just hire fitter assistants ;)

Why do people keep saying that? Gets this K-01 owner confused, EVERY Pentax from about 2010 onwards has a Mirrorless Mode that makes it shoot exactly like the K-01, it's called Mirror Lockup in Live View. Works perfectly fine, although the K-1 and a select few models with a moveable screen do make the best use of that mode.

Replace the GoPro suggested by those above with Insta360's Dual Lens kit, should leave you a couple of hundred spare for decent external mic.

If you need to zoom, shoot in 4K and output HD, then you can zoom in post. If you need to output 4K, you're back to a basic camcorder and spending more money.
