These are complex devices, but in terms of the body
mechanics and electronics, problems are comparatively
rare. Lenses on the other hand, often have defects
(mostly acquired during the manufacturing process).
Lens sample variation is an unfortunate reality...

There is much nonsense on the 'net; all of my AF lenses
can be heard while focusing if I'm near enoug, but the
relevant test is whether or not the camera can be heard
beyond a foot or two - and for video, if the camera noises
can be heard on the audio track with the gain set at
normal levels...

My experience was similar: indoors, the video was good;
outdoors, well.........., NO!;-) Boosting the saturation
some and the sharpening a bit often improved things some,
but the G5/G6 video is FAR better, even though most of the
specs but for sensor size are the same.

Its controls, etc. are similar to those of the GH4, but
the sensor is smaller and the lens zoom range is FAR
larger, both of which would contribute some to the results
not being as good (among other possibilities...). BTW,
"better" to me when referring to lenses describes image
quality, not zoom range. There is generally an inverse
relationship between range and image quality, which
partly explains why the LX100 has a very limited zoom
range...;-) Both the LX7 and LX100 juggle the features
and compromises to favor image quality and lens speed,
although the results are different. The LX7 favors
greater DOF for a given lens stop (all else being equal);
the LX100 favors less DOF, which is desired by some
photographers, but not by me...;-)

There *IS*!!!;-) In good light (and with a good lens used
at its optimum stop[s]), my 1/4th-the-area-of-FF-35mm MFT
cameras can produce still images that put many FF sensor
cameras to shame - and the video image-quality surpasses
that of many VERY expensive pro video cameras - BUT, the
lack of good zooming ability is a distinct disadvantage
with my current cameras for video use...! BTW, sensor
resolution can effect video results strongly, with higher
resolution sensors being more difficult to make look good
shooting video (and stills in low light can also suffer
with using higher resolution sensors). Guess why Sony's
newest ($2500) FF-sensor still camera has "only" 12MP?;-)

Downsizing 4K to 1080 works very well, and it provides the
opportunity to zoom/pan/stabilize in post, etc., and this
can reduce some other issues, too - BUT, at this point,
the frame rate of cameras that shoot 4K are limited to
what I consider to be the very awkwardly slow 24p and 30p
rates. Motion shot at 60p looks FAR better, and this frame
rate limits acceptable shutter speeds FAR less than do the
slower rates, improving sharpness. I've experimented with
synthesizing the extra frames to get 4K to 60p, and this
can work well and look good with some clips and subjects,
but it can risk everything if serious visual artifacts are
introduced during the processing (which is also VERY slow...).
Fun stuff, though!;-)

I've recently updated the MFT-lens reviews here:
http://www.david-ruether-photography.com/MFT-Lenses.htm
I have not yet added two more lenses, one of which is
surprisingly good, the tiny Panasonic 12-32mm. The other
was the 12mm f2 Samyang/Rokinon, returned as unacceptable
after trying three samples (sharp with one of the three,
but all had high levels of CA...).
