Which Pixel Shift mode do you use? With or without motion correction?
Just to expound a little more, these are the different Pixel Shift options:

(1) Pixel Shift (motion correction off) -- this requires tripod support and a completely still scene. Any areas of motion will show as artifacts. If you are shooting RAW you can motion correct with post processing, even if you don't have MC turned on in camera.

(2) Pixel Shift with motion correction -- motion correction can be done in camera or in post, but basically, with motion correction you replace any areas of motion with masked in areas from a single one of the four images you shot. Pentax's DCU uses the first image, but Raw Therapee will allow you to choose any of the four. I think it is important to note two things. First, any scene with lots of motion will require masking of the whole image and you are better off shooting a single image. Two, hand held simply won't work. Pixel shift requires a pixel level adjustment and that is not possible hand held. Having motion correction turned on in the camera simply means that the jpeg will have motion correction applied to it. If you are shooting RAW it won't make a difference one way or the other.

(3) Dynamic Pixel Shift -- this is a hand held pixel shift that is only available on the K-1 II. It isn't terribly useful -- it can only be processed in camera and doesn't allow for RAW image shooting. It takes a long time to process per image, but does reduce noise and improve sharpness for a jpeg image.

My personal rules of thumb are that you should use a tripod and have a still scene and use either the self timer or a remote to trigger the camera for best results. I do typically shoot RAW, process in Raw Therapee and generate a TIFF image that I use as my baseline image for further editing. Raw Therapee has a feature where you can see the motion mask and it lets you know how much movement occurred in a scene. If more than 60 or 70 percent of an image shows motion, then there is probably very little benefit to processing it as a pixel shift and you should just take the best of the four images to work with.

I think the issue of moving subjects is generally over stated if Rawtherapee is used to develop raws.

Motion won't negatively affect the image at all compared to normal single shot.

However those parts with motion won't benefit from pixelshift either. Thing is that even if you shoot a cycle race there might be static parts of the frame benefitting from pixelshift. Wether it's worth it is another question.

Thanks for continuing this thread Rondec. I'm going to make it a plan to give PixelShift a go when out on one of my wildlife hikes, if not this weekend then next. Great images sir.
