Just another CP+ report [pics included]

This year I was again able to attend cp+ on its last day (Sunday). As I knew for me there were no exciting announcements this year I could enjoy it more casually and relaxed.



I queued to try the GR III but thats no camera for me so cannot comment on that much. The touch screen is a welcome addition because it tickles down to other cameras even though focus via touch feels laggy atm.
Then I was caught by a staff member which was presenting a new 2.5D printing technique by Ricoh. They use a 3D-printer technique to give depth to a picture, even make it look like a real painting. They said their biggest picture, which they printed yet, took about 4 hours to print. The actual printer is industrial size (3 meters) atm, it is still a prototype and no price for an actual print decided yet. The actual depth for printing the 2D photo is calculated partly by algorithm and partly manually adjusted.

There are other companies using a similar technique but Ricoh is better in providing a smoother surface on the printing. The pictures looked very good, I can imagine many people buying these kind of pictures.


I got to try the new 11-18mm DA* Zoom and surprisingly it nicely covers the FF circle at 18mm. On lower focal length the black edges start to occur and you need to crop that out, at 11mm it is pretty severe. I also tried the new 35mm, it is a nice lens but comes with all the drawbacks such old lenses have, longitudinal CA, hexagonal bokeh balls, AF not so fast, no WR.





Here the zoom at 18mm FF @F9:


Here on 11mm FF @F9:


Then like JPT I stumbled over the guys with the factory custom made KP. They really enjoyed there time there and we talked and laughed a lot (so I greatly enjoyed it too). So they are enhancing several points on the KP. They have a special black coating on the lens mount which is harder and smoother than the original coating and is used originally by a famous Japanese watchmaker (I think it was Seiko). They havedifferent body colors and a flash top which is attached via the hot shoe. If you want to use a flash on the hot shoe you have to remove it therefore. Then there are the custom grips. They showed me one which was walnut and said its the same material Lexus uses for their steering wheels.
They have also a collaboration with a famous Japanese photographer and will preprogram the user-settings on the camera with that photographers preferred settings. They can use Ricoh’sresources which helps them a lot , so you might also be able to order it from the official website later I guess.
No words on pricing yet because its still in development. They will over it first in Japan and later on overseas (I complained a little that overseas people are eager to get these options too and always are second in line ;)).
Interesting fact, there were two people presenting the custom KP, one is an engineer and the other a designer.The designer told me that he designed the K-30 and the custom flash cover for the KP also inherits this long shape of the flash housing of the K-30.
Here the two guys, the left one is the designer and the one on the right the engineer. They were very commited to their customizations and gladly discussing any comments I made.





Also I saw a new Pentax baseball cap (black with big grey stitched Pentax) at the booth, these were design samples and will be probably available later this year.
At 2pm there was a presentation on the future development on Pentax products hosted in an interview style. They said the 85mm will be available next year. In fact they said that on all lenses on the roadmap xD (the 70-200F4, the large aperture wide DA*, the DA wide zoom and DFA superzoom). The interview guy also noted that the release date of the 70-200mm F4 changed from “spring 2019” to “2019 or later“. It was confirmed there were issues delaying the release of this lens.
I think they also hinted on a new camera for the 100th year release which might be the K-3 successor.

Just to increase the painful wait on the 85mm:

"New" full frame prime without WR is disappointing. Should be really mandatory by now. Feels like the DA Limited rerelease some years ago.
So still waiting for the wide star lens on the roadmap, hopfully this release does not postpone it until 2020 or later ...

Short update on my issues:
Ok so I know now for sure that my problem is the mirror who got stuck occasionally.

I had it acting worse today, freezing the camera on the first shot while being black in the viewfinder. Removing battery, putting it back in and turning on the camera the first thing I heard was the mirror switching down.
Then the camera was working as usual.

I am almost half a year out of warranty. I will try to contact ricoh on this issue but not so much hope they will fix it for free...

My K-1 developed the same problem. It started occusionally producing a completly dark first picture after the camera was in sleep mode or turned off. Now it does it for every first shot after some time in sleep mode or being turned off.

It happens on two different batteries and two different SD-cards so I think I can rule this out.
It seems like the shutter somehow does not open in time for the first shot, after that every picture is ok. Its just damn annoying because in some instances at the second shot the moment I want to capture is gone...

I wonder if thats an electronic problem.

I bought my K-1 very early (probably first batches) and took alot of pictures since then.[COLOR="Silver"]

There is also another guy at the K-1 Facebook group who seems to have the same issues.

Rolling shutter effect when using electronic shutter

The thing is, you want to use ES to avoid shutter shock, which in my experience can occur below 1/400 shutter speeds and therefore you need to be extra carefull and should always shoot also without ES as backup, in case you did not notice any issues while reviewing on the camera.

I had problems with a 135mm lens handheld, thats when I learned that lesson ;).

Ok guys, I have to apologize!

I checked this today again and even though the camera makes this noise, which I always associated with aperture closing, it does not move the diaphragm.

I guess I got fooled by the noise from that motor or spring load or whatever.

Yes it does xD.
As already told, I have confirmed this with my K10D already.
When I press the green button there I hear and see the aperture closing temporarily for correct metering.
My K-1 on the other hand does not do this while using the same lens with same adapter.

FYI: The genuine pentax m42 to K adapters are still for sale in Japan, where I got mine.

I noticed my old m42 Takumar lenses will not set the correct aperture while having the lens switch on "auto" und pressing the green button for metering.
This works with my old K-10D and I was always wondering why it is not working with my K-1, anyone else noticed that? Is this maybe just a setting or ist the K-1 missing something here which the older cameras had?


I just recently tried this with my SMC Takumar 135mm F3.5 using the genuine Pentax m42 to K adapter.

PS removes moire has less noise on same ISO value and better colors.
I think these are all noticeable in larger prints.

Btw. you can shoot handheld PS with the K-1 at good light and steady hand, or just support on a wall etc. just like you would shoot pictures with long exposures without SR ;).

Yes it will.
Read the dpreview review of the KP on the high ISO performance.
They improve color and contrast in cost of slightly less details (saw only the comparison on ISO 25.600 live so can not comment much on lower ISOs).

If you are worried about this you should wait until the K-1 II reviews arrive.

I asked for 4) at CP+ and the answer was no I am pretty sure this applies to 5) also.

The accerator chip is just a unit before the CPU, as they did not change any of the other infrastructure I would not expect any changes on buffer rate.

Judging from the answers of the pentax interview it was confirmed that all the changes of the image data are made before the regulat picture pipeline on the very raw data.

Hope Adam has the opportunity to do some Astrotracer tests for example at ISO 1600 and compare the raw files if there are some stars eaten or not.

Thanks for the reply.

Makes sense and that is what I thought too but at least in manual mode there should be a way to force it off?

Usually one is expecting to see a darker exposure if that happens in manuel mode.

Hi, I have recently noticed a strange behavior in the video mode of my K-1 which I try to understand. Maybe someone here can help me with it.

I use my DA* 55 in manual focus in video mode in AV mode with fixed aperture of 2.0. When I focus in/out I hear an aperture change at one point, I think it happens everytime at the same focus distance. So I looked in front of the lens and indeed there is an aperture change.
Actually it happend in every mode, even in manual mode.

Is this a bug or do I have to check a special setting to disable this?

As I try to avoid any clicking sound, so its not recorded on the audio track, this is really annoying.

Thats actually a very nice description by you.
I was wondering where I would might want to use that mode and could not come up with an idea.
But that totally makes sense. The question is how good does it work under these conditions. And could it help like on a tripod during strong winds and when using a long tele lens (I can remember one scenario where it was almost inpossible for me to use PS under these circumstances).

To be honest regular handheld PS shift are not imossible with the K-1.
I did already handheld shots with the regular pixel shift mode which turned out ok (depends on exposure time and technique, pretty similiar to taking long exposures handheld). Even in the original K-1 presentations Haseo (one of the prof. photographers) mentioned he did it on one of his models and it worked.

The point is the K-1 is already that good, because they put everything in which was available that time, so that its hard for them to improve it without an complete overhaul.

Which they obviously can not do in 2 years.

When talking to the staff I think she knews that, because she showed sympathie for me when she had to admit the limits of the new features (like mechanical shutter at dynamic pixel shift / no speed improvements for UI or video).

Unfortunately I did not ask specifically but I would expect they are not showcasing JPEG performance in their top of the line professional camera, but you never know.

At least the camera output on the original K-1 was looking like raw output which I am used to.

To be honest, I was a little disappointed with what I was seeing. I was expecting the K-1 II to be better in every aspect, which might not be true.
I think my post is reflecting this.

Concerning high ISO, in my opinion you were trading better contrast and color for a little bit of details.

I know its hard to judge by the sample I provided but I was not allowed to take pictures on my SD-Cards.

As I said I only got a little glimpse on the camera so lets wait for the reviews how it turns out ;).

I visited CP+ today and had a touch and try with the new K-1 II with an english speaking staff.
After that I went to their small special booth where they show case the new high iso performance of the k-1 II with taking a picture simultaneously on the old and the new K-1 model and let you compare the results directly on the screen.

All the K-1 II new features are provided by the new accelerator unit, as we know, which only helps in faster processing the pictures and therefore allow new software tweaks / algorythms (like better tracking AF-C / better high ISO performance due to noise processing? [read below] and the new pixel shift mode).
The main processor or other parts have not changed though. Therefore there is no benefit to other processor intensive tasks like faster UI (which I hoped for :( ).
Also there is no benefit for video capturing because it does not use that unit (I specifically asked). Also they do not fokus on video and they had no information on a firmware update providing mechanical SR for video. They clearly stated that Pentax focuses not on video but picture taking.

The new pixelshift mode is taking pictures in interval mode with mechanical shutter and takes therefore longer than the real pixel shift. Which uses electronical shutter and is taking pictures faster in sequence (they confirmed this also).

The high ISO shots were compared at ISO 25.600.
The K-1 II had better colors with less false colors and more contrast.
But the edges were more smeared! It looked as if there is some mild noise reduction applied even if noise reduction is turned off.
One could easily see that the original K-1 picture had more defined edges and is less smeared. Like they had the number „4“ on a wine bottle and the inner space of the „4“ was smeared into yellowisch on the K-1 II whereas in the K-1 picture this was not the case.

But keep in mind that really was pixel peeping in max zoom, so I am sure nobody expects perfectly useable images at ISO 25.600 in 1:1 view. So due to better colors and higher contrast the overall picture will probably look better than on the original K-1.
Still I do not like that I have to give up details compared to the original K-1 picture. Especiallly if I am not able to turn these “improvements” of if I prefer more details instead.

Anyhow I can just advice anybody to think the hardware upgrade through and wait for reviews to make an informed decision.

Actually I wanted to update the hardware in my K-1 because I totally like what pentax is doing there. Especially from the environmental point of view.
But now I am not so sure if there is really a 500€ improvement in the K-1 II.
I will definitely wait for reviews until I decide.

Also please take these things with a grain of salt. Even if I wrote “they” I spoke only to one staff member so there might be some misinterpretations /-informations going on xD.

Here is a photo I took of the high ISO comparison shown on a big TV screen at the booth. You could even see the slight smearing there, take a look at the letters:

https://www.dropbox.com/s/r2ynvdykydzb5ro/IMGP6201.JPG?dl=1

I asked about the 50mm star lens release, they were only allowed to state spring but hinted on cherryblossom season (end of march / april).
They also had a flyer about a completly reworked ImageSync app in spring (fingers crossed).

I also asked Sigma about K-Mount lenses -> unfortunately there are no plans to release new lenses in K-Mount. Even if the person I asked understand our needs as she has a friend who also uses pentax cameras and is bugging here about this xD.
Same information on Zeiss lenses.

If interested I could upload some images from the exhibiton next week when I am back at at my laptop.

If they could easily negate the jelly effect like this it wouldnt be there in the first place.
Even though its possible they use a technical improved SR I believe this camera is more like a small upgrade with available ressources than introducing such a major novelty.

I think so too. Also in the German pxp-press kit was stated the dynamic pixel shift has 70% of the performance of traditional pixel shift.

I think I read somewhere before that the dynamic pixel shift might be applied during regular interval-shooting. So as rondec said, they just improved their picture mapping algorithm to match the pictures taken in the intervall shooting.

It does make sense, this way (using the regular mechanical shutter) they dont have the disadvantages of ES, like jelley effect while moving or led flickering or no SR. Of course they also lose the benefit of eliminating shutter shock in slower exposure times. This might be one reason why they did mention the 70%. In my experience ES during regular pixel shift is the main reason for a sharper picture.

The dynamic pixel shift might in this way only bring advantages for better ISO performance and eliminating moire, not so much for sharpness (compared to a single ES shot).

Anyhow, i hope they bring a substantial increase in operating speed which is worth the upgrade :).
