Dpreview: “Pentax K-1’s Pixel Shift challenges medium-format dynamic range”

Today Dpreview published an interesting article called “Pentax K-1’s Pixel Shift challenges medium-format dynamic range“:

Pentax K-1 vs Nikon D810 comparison

“In conclusion, the K-1 gives one of the best Raw dynamic range results we’ve ever seen, when shooting in single shot mode and absolutely outstanding results in circumstances where you can use the pixel shift mode. The multiple sampling of the same scene effectively gives a 2EV dynamic range boost, meaning it out-performs both the D810 and the 645Z by a comfortable margin. Less noise (though multiple captures) and multiple 14-bit values at every pixel mean it can give outstanding levels of DR for static scenes where you can use the Pixel Shift mode.”

    This is impressive. Pentax did a great job with this camera.

  • damn i wish nikon and pentax worked together to bring pixel shift and af fine tune combined. it would be a dream

      While this is a great thing built into the K-1 you can do this on your own. If you manually stack a series of images you’ll get more dynamic range and less noise.

      Heres a Thom Hogan article on the subject:

        Yes, but if you stack four single images from Nikon, and four single ‘pixel-shifted’ photographs from Pentax, results from the K-1 will be better anyway: more data in, more data out, and any given ‘pixel-shifted’ image already contains 4 times more information about colour than single frame from Nikon… In other words – you can do extra job to get similar results from Nikon, but if you’ll do the same extra job with Pentax RAWs, you get better results again…

    Really impressive results, but then again this trick works on stationary subjects only.

    Nonetheless, hopefully multi-sampling technology would make it to just every DLSR in the future.

    • Aspa

      Yeah, but ‘stationary subjects only’ means great numbers of photographic scenarios which now are executed with expensive medium formats: products, pro-grade food photography, hi-detail archives, science, some macro and so on. I can even imagine some landscape photographs possible to be done with pixel shift, architecture in certain conditions etc. Even better – a portraits! Isn’t the Branizer method even more demanding in terms of ‘stationary subject’ than pixel shifting? Ok, the ‘large medium look’ is not the goal here in terms of DOF, but in terms of tonal range – yes, is possible I think.
