Thanks Vitaliy. Someday when I have more lighting for cinematography I'll think about it as well. Money has to go where most needed!

I picked up a barely used in box g6 and I'm super happy!

The K-1's Pixel Shift Resolution mode takes four consecutive shots and moves the sensor by a single pixel each time. This means that each of the original pixel positions gets sampled by a red, a blue and two green pixels. This has a few major benefits. First, it removes the need to demosaic: you don’t have to interpolate data from the surrounding area to build up color information, which leads to less color aliasing. It also brings a modest increase in resolution because you're sampling luminance (green) information at every pixel position and not effectively blurring it by borrowing it from surrounding pixels. The increased resolution can easily be seen by looking at the color resolution targets, or looking at the text in the center of the studio scene, which shows no aliasing and can be read down to the very last line.

We have found that some SIGMA interchangeable lenses for Pentax mount could leave a small scratch on part of the camera body when they are attached to the PENTAX K-1, released by RICOH IMAGING COMPANY, LTD. on April 28th, 2016. In this circumstance, please do not use the following lenses for Pentax mount on the PENTAX K-1.

We are planning to provide a repair service to replace a part of the lens for this issue. We will make a further announcement on our website when specific details, such as the service period, are finalized.

K-1 is good value for money. It's well built, offers plenty of user-adjustable controls (most of them genuinely useful) and comes with a relatively 'affordable' price tag, when compared with similar cameras in its category. In addition, our tests show it to be a competent performer when shooting still photos.

Not good in video except one mode in FF

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.
