DIY pixel shift
1

As most here know, the pixel shift technologies of Pentax and Olympus cancel out the moire caused by the bayer sensor and increase the resolution (and probably the low light performance as well).

I mainly take photographs of completely non-moving subjects. I was wondering, is it possible to mimic pixel shift with a 'normal' bayer sensor camera?

This is what I was thinking:

Stage 1: Custom rig consisting of a very solid base (against tremors), with a camera mount that has micrometers attached that can move the camera along the y and z axis. The micrometers will move the camera a pixel in each direction, taking 4 or 6 photographs in total, depending on whether you want to do it like olympus or pentax.

Stage 2: Photoshop the images. I am not a photoshop wizard so I am not sure how best to tackle this. Input is welcome.

Potential problems:

Shutter/mirror shake could misalign the camera after a shot. To cirumvent this, would a mirrorless with electronic shutter be more advisable?

Manually adjusting the micrometers could misalign the camera. This could be resolved by a heavy base where the camera is attached to, or remotely operated micrometers.

PS: I understand that to gain increased resolution with the same camera, you could also use a longer focal length to take panorama shots which are then stitched together in photoshop. But, you should look at this DIY pixel shift as a' technology demonstrator' instead.
