Samples of Pentax K-1 Pixel Shift Resolution system - pre-production firmware

Hi guys,

I just got my hands on a pre-production K-1, one of very few out of Tokyo. Just wanna share how impressive is the new Pixel Shift Resolution.

Color rendition and very fine details are what is being enhanced in the PSR mode. Colour become much more accurate . Also in my test PSR reveals very fine color details that are normally lost with single shot file, this is not visible in this test but I'll upload a few more soon.

Surprising it also seems to correct some colour cast, as you can see in the 2nd 100% crop, the reddish cast is gone. No adjustment to lighting condition or PP involved. These are all OOC JPEGs.

The usual limitation with PSR applies, the camera has to be very still and no flash/strobe possible.

Full image comparison:

The difference is subtle, but it's there. Thanks for sharing.

Are you SURE you have these labelled correctly. In both the full download and the zoomed corners, I see higher resolution in the right hand frames, which you label as "Without pixel shift".

In the famous flower arrangement still life released by Ricoh, the pixel shift effect was very apparent and impressive. Here it is more subtle, and negative if the labels are correct.

Pretty sure I had it correct, here's a few more fresh off the camera. Also include two modes of PSR (MC and non-MC).

I see no difference whatsoever between non-MC and MC. What is MC?

I'm guessing Motion Control or Motion Correction or whatever

Admittedly, I'm just viewing on a Surface Pro 3 right now but other than color rendition, I have a hard time seeing a difference in the photos.

That would explain it then; there is no motion!

I'm viewing on a very high resolution 3840x2160 Dell UP3214Q monitor.

I agree.

The left images has sharper edges in both examples imo

I cannot say for sure what is MC as this doesn't come with a manual, and the only people that can answer and explain is in Tokyo. My guess is motion correction also.

I have the camera with me permanently so if there's suggestion of what to shoot just let me know. Also another potential reason is this one is running on a pre-1.0 firmware, quite a few bugs around in terms of controls and customisability so can't guarantee PSR is working as it should.

I might be off here but i think it could be badly chosen texture to exemplify the benefits of PS and the difference, though present, is minimal.

Also, the color cast in the non PS image could be from the shutter synchronization with the frequency flicker of the artificial light.
These tests should be done with care and take into account all these variables.

thanks

stunning detail, with or without - to me the pixel-shifted images gain more in edge contrast and colour depth than in sharpness per se - as I believe they should - it's a a great thing to have available

Subtle is right, I could hardly tell the difference!

I see ... the images are correctly named. The pixel shifted image is not only sharper but also color corrected I think. And that it actually lightens up the colors on that pink and burlap book covers (true to life) in this case. I think this is great since now on the the red and pink colors in the image at least pixel shifted ones will stay in check.

For me, the difference on the red fabric is very clear. Maybe, those who use very high resolution monitors can't see it because pixels are to small
