Test frame taken with the Schneider-Kreuznach Xenon-Zirconia line scan lens described here at the optimal f-stop of f/4.8, Pentax K-1 in Pixelshift mode. No CA or vignetting correction, no noise reduction, just minimal sharpening to counter the effect of jpeg compression.
Just a test between the affects of the unique Aperture Blades on the Sol 45, here's a pixelshifed shot with them over the front element.

Focus Shift + Pixel Shift
When Nikon approached me to test out the newest and most nerdy thing ever, I was very excited to see what they had come up with!
Pixel Shift is an option where the camera moves the sensor during a series of captures. This series is then merged in the Nikon NX Studio software. In this case, the pixel shift option was set to the maximum capture option of 32 images. The camera exposed an image then moved the sensor… about half the width of a single pixel… and exposed the next one. For 32 images. Those 32 NEF (RAW) files were merged into one massive NEFX raw file that now has a resolution of about 180,000,000 pixels.
Focus Shift Shooting is an option where the camera makes an exposure then shifts focus to a different plane and makes another exposure. The cool part is that the camera is automatically setting the shift movement so that a series of images can be stacked on post in such a way to increase the depth of the PLANE of focus. This results in a subject the can have a nearly unlimited amount of the subject focus. Not just more depth of field, but depth of actual in focus.
The Z8 FW 3.0 is the first time anyone has offered both at the same time on a full frame professional camera.
This version, like the pink ranunculus Japan chose to use for the launch of FW 3.0 was created by the careful merging and stacking of about 1,600 separate RAW images.
50 Focus Shift Images each with a 32-image pixel shift were captured in camera. Each of the pixel-shift images were combined and then exported as a 16-bit TIF (1.09GB) each of the 50 TIFs were then brought onto Helicon Soft stacking software. The software automatically stacked the TIFs into a single file that had the desired part of the frame in focus. That stacked image was brought into Photoshop for resizing and final adjustments.
