Hi Tupp
That's a beautiful video. The only thing that interests me is the beauty of the footage I can get. I think the Panasonic is truly impressive, but the EOS M is a fantastic tool in its own way. From what I've seen the Fujian lens is also great when you play to its strengths.
I don't regard 4K as particularly important in my own work at this stage, but flexibility is a different matter. In order to be able to use old C-Mount lenses that will only cover a tiny sensor, I bought a GoPro 4 with the intention of doing the Backbone mod, so 4K might be a factor then, as it can be turned into lovely 1080p footage -the trade-off is the the ProTune settings are still pretty inflexible.
Another great thing about the Canon is that I can shoot long scenes without it overheating, which is very important for the type of filming that interests me.

Your EOSM is a great camera, and you can significantly extend its capabilities by loading Tragic Lantern onto it.
 
I use TL on my EOSM to boost the bit rate and to shoot all "I" frames with H264.  Here is an extreme test I did with the EOSM, TL and, mostly, the quirky Fujian 35mm f1.7 CCTV lens.  Although I pushed the EOSM past it's DR limits (obvious FPN and just plain old noise), note that there is significantly reduced compression artifacting.
 
Also, the strange focal plane of that c-mount Fujian 35mm really "pops" with an APS-C camera, such as the EOSM.  Here is a better example of the Fujian's wonkiness on an EOSM (shot by maxotics).
 
Other great things about the EOSM line, is that there is a focal reducer for it that gives almost a 1:1 crop factor (in addition to extra brightness) and that there are tilt and tilt-shift adapters for it, if one desires interesting focus effects or if one merely wants to Scheimpflug.  Of course, with the shallow flange-focal distance of the EF-M mount, there are zillions of lenses that can be adapted to the EOSM.
 
To me, it is sometimes more valuable than 4K and high dynamic range to have the TL build combined with the ability to use these special attachments and a huge variety of lenses.
 

Hi everybody, my first comment on this forum, very nice to meet you.
I like Andrew's review for EOS M3, and I find it to the point and I find very useful the videos "Japanese Garden" and the "Studio Test Scene".
Well I am from the first who bought EOS M3 body from Amazon Japan at under $500 with free EVF included.
I already have a Nikon D800 and when I compared it with EOS M3 in movie mode side by side, I was impressed to see that the EOS M3 video is much more clear and full of details than this of D800.
After I liked the freedom that M3 gives me: small size, tilting screen, standard external microphone port, focus peaking that make manual focus quick, and a variety of lenses to choose from Canon, or Nikon, or legacy Pentax, Tamron etc.
You cannot find all these at this price.  Not even an external microphone port unless you go more over $1.000.
I also want to inform other M3 users that if you search the settings in "Picture Style" you will get a movie output much more rich in details: not only remove sharpness but remove contrast as well.
But I was really surprised to see that magnification assist for MF doesn’t work in movie mode, while it offers focus peaking, which is related and has to work together with MF assist. I hope that they fix this, it is crazy: every time i want to fine focus or to check the accuracy of the focus peaking, I have to: rotate the selector from movie to photo mode> fine focus>rotate again the selector to movie mode.
In general am happy with this camera and for this I made a short "Low Light High ISO Movie Test" which i can share with you:
 
 
Chipped and unchipped lenses were used for shooting the samples of this movie, which are:
1. Nikkor 50mm f/1.4 non-Ai (adapter used).
2. Tamron Adaptall-2 SP 60-300mm f/3.8-5.4 (23A).
3. Tokina 12-24mm f/4 AT-X 124AF Pro DX II for Nikon (adapter used).
4. Tamron SP AF 17-50mm f/2.8 XR Di II LD IF for Canon.
And here is a picture of EOS M3 with the lens: Tamron Adaptall-2 SP 60-300mm f/3.8-5.4 (23A).  With this long lens, the first clips of the movie test were shot:

Best Regards!
