K3 II pixel-shift samples on IR. I'm impressed

Imaging Resource have posted a number of pixel-shift samples from the K3 II.

Pentax K-3 II Review: First Shots - Tech2

Only JPEGs so far but they compare to the K3, D810 and Olympus OMD EM-5 II.

Anyone who doubted the difference that this feature could make to resolution should take a look (and everyone else!)

They look great! I wonder if they shot jpeg or, if raw, how they got them to work. The discussion here seems to point to raw format not working correctly with most programs.

I was mildly amused by the comments and the responses regarding PS in combination with SR and/or continuous shooting. While they were old comments made before the camera made its appearance, the answers are intuitively obvious. The recently released manual has a table with a compatibility matrix. In simplest terms, when PS is used, one is limited to a single exposure* with no SR or AA filter emulation.

Duh!

Don't forget the 645Z comparison shots!

I agree. I am disappointed that the RAW files cannot be properly read by non-Pentax software, but it may well be worth the tradeoff.

I wonder if, with a faster camera CPU perhaps, it will ever be possible to run pixel shift without the limitations on it at the moment - tripod, static target etc? To make it work in normal, everyday shooting.

From the IR samples, it looks like it could be very useful for low-light, low-noise shooting (eg of gigs, indoor events like weddings), but nothing stays static there.

It will be interesting to see how Pentax evolves this.

What impressed me most was the comparison shots between K-3 II and Nikon D810. in the Red and Yellow Fabric test.As Article says the difference isnt Night & Day but its very noticeable.

Me too. Red/yellow performance is an issue with many digital cameras and to see these clean results sort of sent shivers up my spine.

This camera is complicating things! I wasn't planning to upgrade from the K3 until the FF comes out, but this feature and the inbuilt GPS (Astro tracer) are making me think twice... Its about time Ricoh started announcing some details on the FF I think!

The pixel-shift K-3II images are quite impressive. If there were not a Pentax ff body expected soon, I would buy one. Imagine that body with pixel-shift versus the D810.


I would like to see some pixel-shift images with motion in the frame to gauge how the tech will work for landscapes with moving water or wind-driven foliage.

seems to be a "one use of the shake reduction system at a time" sort of thing. I wonder how it will get along with flash as well.

Yes there's something very satisfying about getting this level of pixel-level quality - reminds me of the satisfaction of seeing sharp details emerging through the grain of film. Trouble is, the difference between the pixel-shifted and normal exposures from the same camera is such that once used, I think many of us may not want to go back to the bad old days of bayer interpolation. Sigma may do well out of this! After this I'm expecting the DNGs to be phenomenal.

So if the DNG files are nearly 4x the size of normal DNGs, I take it we are looking at files which store all the luminance data from four captures, which is subsequently demosaiced in PP, rather than the demosaicing happening in-camera and a file output with full colour data at each pixel? I was hoping for the latter, but I'm not complaining.
