Pixel Shift and Astrotracer were why I got the Pentax. I currently have only one lens for it, the Sigma 17-70 mm Contemporary.
Here’s some Fall ground cover (no motion). First a thumb-nail image:
Expanded views, with non-pixel-shift on left, ps thru DCU 5.6 in center, and RT 5.2 pixel shift on right. I used the profile Ingo supplied for the RT image, and to the DCU images I applied 0.4 px of Gaussian sharpening. This first comparison is at 200%:
And this is at 400%
If I’m using a tripod, I’m pretty much always shooting pixel-shift. (unless it’s Astrotracer mode…)
