I have attached two pictures, one by her and one by me, from our recent Fall Colors shoot. They were both taken of distant landscapes in the same area. She was using an Olympus E-PL1 with only a rear LCD, and I was using an Olympus E-M10 with a viewfinder.
She was relying on the camera stabilization system, and I had it on but never trust it. So, I was trying to be a human tripod, but she was not. And then that arch enemy, the shaking gremlin, brings his unsettling ways.
In her photo, though well composed, the softness is evident. In mine, I think a higher degree of clarity seems to be apparent. I doubt the difference in megapixels is relevant (only a difference of 4 mp). So, I assume it is the Gremlin.
How have you managed to solve stability issues when hand holding?

I don't see much evidence of camera shake. What I DO see looks like very slight diffraction limiting of sharpness combined with a different Anti-Aliasing filter on the sensor, and around 25% lower megapixel count.
The sharpening character of these images is also very different. Was there any post-processing involving multiple saves as a JPEG? What was the file quality setting... on the camera and in post-processing if there was any?
I also see a big difference in focal length and lens. You were using a 12-32mm Lumix at 14mm (close to its optimal performance), at 1/800 second and f/8, ISO 400. She was using a 42mm focal length (indeterminate lens, probably the long end of a short kit zoom) at f/7.1 and 1/125, ISO 200. The E-PL1 has three stops of anti-shake IBIS, so I really don't think the shutter speed or hand-held situation is the issue. It COULD be the lens. If it's a typical or early 14-42mm Micro 4/3 zoom, the 42mm end usually is not very sharp. Also, is her lens CLEAN on both front and back elements?
Many older photographers are not aware of the diffraction limiting of sharpness phenomenon. But here it is: As you stop down any lens, at SOME POINT, it starts to introduce diffraction (scattering of light rays coming across the edges of the aperture). As you stop down, diffraction doubles with each f/stop.
Many older photographers who grew up with medium format and large format film cameras also think they need to use small apertures on their Micro 4/3 and APS-C cameras to achieve sufficient depth of field in scenes such as you show here. That is false! Because the lenses are much shorter, depth of field is much greater at wider apertures. I wouldn't use an aperture smaller than f/5.6 for scenes such as you posted.
On Micro 4/3 cameras, diffraction happens at an aperture about TWO STOPS WIDER than on full frame cameras of the same megapixel count. So if you were to plot the MTF curve (sharpness) of a Micro 4/3 lens, it would be sharpest at apertures of f/5.6 and wider. I have three f/2.8 Lumix lenses, and all of them are sharp from f/2.8 to f/5.6, sharpest at f/4, and so soft as to be useless at f/16 to f/22.
One of my favorite tools to use on my Lumix GH4/Lumix lenses is a neutral density filter. It allows me to work at slow shutter speeds needed for video (1/25 for 24 fps "film," 1/30 or 1/60 for HD and 4K "TV" video). It also allows me to use wider apertures for still photography when I want less depth of field.
I would probably do a controlled comparison test of these cameras, using a tripod. Turn off IBIS, use the same lens on both cameras, and photograph the same stationary subject in the same light. Use every aperture on the lens. Then swap lenses and do it again. Compare unadjusted images...
