Firmware update for shake reduktion in videomode. K-1 and KP.

I quote myself and answer myself with a quote from todays initial review of K-3 Mark III in Dpreview. :cool:
Finally!

"Ricoh says the new IS system is quiet enough to be used during video capture, meaning the K-3 III is able to offer 3-axis (Roll, pitch and yaw) correction using mechanical stabilization, rather than the digital IS used in previous models."

Sony alpha-K-mount adapter with af!

I´ve been hoarding K-mount lenses through the years and I´ve been waiting for a Pentax with descent video, with ibis and advanced autofocus. So I only have to spend money for one camera. If Fujifilm can do it, why not Pentax? It doesn´t decrease quality for stills. I thought the new flagship aps-c would have theese videofunctions so I could sell my Panasonic GH5. It doesn´t seem so and the price is huge.

The adapter is first aimed at screwdrive and mechanical aperturecontrol. That seems logical cause thats not protected by licenses? The electronic steering is all about software and more suiteable for autofocus during video.

Still no firmware with sr in videmode or better hdmi for K-1 and KP and here comes K-1 II also without those functions.
So what do you think, guys. Will it just appear on the next high-end aps-c? Along with 1080p 60fps and even 4K? Aps-c/super 35 seems to be a more attractive format for video also.

Besides, I wasn´t asking. They throw it at us. It will be useful for many...I think. So why not? And if we get a good HDMI, it´s not so much more to ask for. Excellent camera for stills, and quite ok for video.

Thanks guys!
Your answers really shed light over the subject for me. I draw the conclusion that videoquality is probably going to evolve much more and faster than the iq for stills, due to faster processors that work on the data from sensors with more 40 mpix and more. 40 mpix gives 5 pixels to every singel 4K-pixel. Adding the data in the right way will improve dynamic and snr.
And due to better SR of course! To go back to the original topic..

Am I right?

Ok, I understand now. Stills and video ARE very different things when it comes to a cameras level of performance, as I suspected. And I hope that Pentax throw in some more improvements in firmware than the mechanical SR. April is soon now...

But I meant the low score for a7s II!
Low is bad.
a7s II has also only 12 mpix.

But the DxoMark-score which I refered to then? The sports/lowlight/ISO. I guess thats all about signal/noise.

The 36 mpix is not so much worse if you scale it down. And why do the a7s II has a lower score than both K-1 and a7s?

But isn´t it the bigger sensorarea (also) that gives FF a better signal/noise ratio? For the same angle of view you use more area for gathering the light, (at a longer focal length).

For stills I learned that it is 1-3 stops better, and that is if you compare the same pixel density. The Sony 16 mpix sensor (K-5) to the Sony 36 mpix sensor (K-1) f.ex.
If you see the points on Dxomarks, the K-1 has a BETTER low-light/ISO-value than a7s II! Btw, why is a7s so superior to the a7s II?

Thanks for your very useful answer PiDicus Rex.

Have Sony paid Dxomark something? Isn´t it a strange way to express that the newer and much more expensive camera actually is a step (several?) backwards? :P

Comparison 1: Sony A7S II versus Sony A7S versus Sony A7R II: Impressive high ISO DR - DxOMark

Comparison 1: Sony A7S II versus Sony A7S versus Sony A7R II: Impressive high ISO DR - DxOMark

Excellent? :hmm:

Measurements: Excellent low-light score - DxOMark

Thanks Steve. I remember that film.
Another question. Did the more uncompressed fileformat of K-7 and K-5 had more useful information for postprocessing than K-1´s mp4?

Why I´m asking for what the "videopeople" or "videonerds" say and think is only because I don´t see so much discussion about making video with K-1 or other Pentax cameras. This videosection of the forum doesn´t have so much activity as I expected. Then I also seen a lot of reviews where they are scornful to the K-1´s videomode.
I started a videocourse also and getting more and more into video. Was thinking if I had to change system just because I get higher demands for videofunctions. I want to avoid that cause I have invested in so many great pentaxlenses that render skintones so nice. With those lenses and a good camera to record, you could create great, artful video. Of course, you can use those lenses on the C100 with adapter, but then you cant use the fantastic pdaf.

I was very excited also when I heard ricoh will give us SR! The digital sr was a joke.

The Canon C100 was a dream and I havent compared K-1 with 5D MkIII. But it made me start thinking of the difference in hardware and software between dslr and more dedicated videocameras. The c100 has a fan that cools the sensor f.ex. Is it a problem with K-1, that it looses colours when filming longer periods?

So what you think Steve, is that the K-1 is on pair with Canon 5D MkIII, Canon 70-80D and Panasonic m4/3 when it comes to the eastethics of videofiles? (Up to 30 fps 1080p) And the critic is exaggarated?

Finally. When do you guys think that K-mount have a camera with pdaf while filming, and at least 60 fps 1080p? I hope I soon got one with great mechanical SR (K-1). The sound I record with external mic or a soundunit like Zoom, like most "videopeople". :)

Thanks Pidicus! I was writing my latest post while you answered.



---------- Post added 03-12-2017 at 03:01 PM ----------

Thanks again PiDicus Rex.
This was the kind of information and reasoning I was searching for. Now I understand more what the C100 is also. Makes me even more disappointed on the old hardware in K-1. But it´s relatively cheap, so..

But doesnt FF video compared to aps video gives the same big advantage when it comes to noise and iso as for stills? I mean, the a7s is used by pros in many situations. And the bigger sensor must give SOMETHING to the eastethic also, or???!

Yes, I think its very easy o set up, in manual mode. Also the sound when you use an external microphone. But I want to hear the videonerds say something about the aesthetics of the videoperformance of K-1. Maybe Ricoh will put some other videoformat in the firmware than the compressed mp4 also? Is that possible?
One thing that really sucks compared to tha Canon C100 is the autofocus while filming. The C100 seem to have the dualpixel PDAF that doesnt hunt. The K-1 have only contrastfocus and it´s impossible to use it while filming.

---------- Post added 03-11-2017 at 10:57 PM ----------



I hope it´s so simple.
But I think videocameras software is something slightly different. I still want to hear what the "videopeople" says. But maybe there arent any of them using Pentax... :(

Does anyone has a hint when the firmware update for K-1 an KP will come?
And how good will the shake-reduction in videomode be?

For stills I read somewhere that Pentax new SR-system is better then Canons in-lens SR. Does that goes for video also?

Since I used a Canon C100 with stabilized 24-105/f4, I have a reference there. I also read that the Canon stab. system wasnt so good for video and that new videocameras with IBIS are better. You agree? I have nothing else to compare with, but I think the Canon SR-system in lens and with C100 made a very good job.

What do you think about other qualities of the videofiles of K-1?
I must say that the files from Canon C100 has very nice colours and feeling. Can a dslr for stills compete with that? Is it also depending on the firmware or has the C100 completely different hardware compared to Canons dslr?

Yesterday I took out the battery without switching off power. I forgot, and I noticed the display went black. When I put in another battery the camera had lost all the changes I had done in the settings. The first thing I saw was default color in the the display. I had not saved any usersettings. Camera in Av only, so far.

Then I made some changes in settings and took out battery and put it in again (power on), just to see. Now nothing happened.

When you open the little "door" to the memorycards the camera seems to shut off some functions. That is not the case when the batterydoor is opened.
I wont do it again.

Any thoughts about this? Anyone else had experience of unintentional factoryreset?

Could a cropped videomode in new firmware make it possible to get at least 1080/60p?

Use, for example, an aps-c sized part of the sensor, which when it comes to filming is big enough for most purposes.
Is it the process to count down pixelinfo from every pixel in the full format to HD that steals processorpower and limits it to 1080/30p?

And same question for 4K. Could it be possible to get it if you just use that size of the sensor that gives exact amount of pixels for 4K? That will actually be a little smaller than aps-c. But Panasonic GH4 uses a much smaller sensorarea.
