To add to other reviews here, let me highlight
the differences between the GM1 and the larger Lumix GX7 introduced this
year which has the identical, excellent, image sensor. General comments
on why I chose the GM1 over other µ4/3 cameras at the end. I'll borrow
liberally from information available in several online reviews.
First, although the sensor is identical (and available image quality identical to the very well reviewed GX7), there are a few differences in capabilities (both better and worse):
1. The GM1 can achieve 1/16,000 maximum shutter speed. The GX7 can do 1/8,000. Although not useful in most shots, it is equivalent to having an extra stop of built-in ND filter for wide open aperture shots in bright light. (There is not built-in ND filter, but such a fast maximum shutter speed achieves the same benefit).
2. The flash sync is 1/50 on the GM1. (In my view this is just not a concern. Anyone looking for flexibility and
performance in flash photography is not interested in a compact camera without a flash hotshoe like the GM1. However, the pop up flash can be held tilted up towards the ceiling, so the most useful application of a flash as bounce fill, in my view, is built right in conveniently.)
3. There is no bulb exposure available (e.g. shutter open for as long as you need). This is because the sensor needs to dissipate heat, and in a small camera body it's hard for the CMOS chip to dissipate heat for more than a minute. How often do you use exposures >one minute?
4. There is only 1080/60i video, not 60p. Same reason as above--60p generates more heat than the small camera body can effectively dissipate. With that said, you can choose H.264 as a codec and 24p for very easily editable, movie like HD video.
