Sure :)and the rest were Canon and Nikon
I have different uses for cameras, especially the mirrorless type, than what's mentioned in this video
Our use is nearly always a combination of stills and video.
Since video requires more accessories, like a cage, a preamp, sometimes external power, using a camera like the gh4 vs. the 70d the size/weight advantage for me is not that much different.
In fact, after using our RED 1's and scarlet so often now anything under 12 pounds feels lightweight.
I went with the gh3's because they offered decent video and for some scenes in video good autofocus tracking, pretty good for stills.
Later bought the olympus omd em5 and em1, just because I wanted to. The em5 producing a better still file but the em-1 a much better camera.
But the kicker on the smaller 4/3 cameras is the small sensor. I don't want 100% blurred background focus, but do want to be able to control the look and separate the main subject and the 4/3 cameras are difficult to do that with.
So for our current project we are shooting with the 70d for motion imagery, my 1dx for stills as it uses the same lens set and our RED scarlet with a Canon mount once again to use the same lens set.
Bottom line the 4/3's stay in the case and so far I've only used them for scenes with car mounts.
I wanted very much to go wit the Sony A series, the 7s and 7R as I felt they would give me the best of both worlds, high quality stills and decent video but passed due to the lack of tracking focuses on both cameras and the fact the 7s in video will skew with jello effect way too easily.
Personally, the best camera of the lot, which is more of a hybrid than mirrorless is the 70d because with an apsc format the skew is less than full frame, the video follow focus is good, high iso to around 1200 or 1600 in a pinch is fine as long as I grade in Resolve.
What made the 70d come alive is the technicolor profile which gets very close to matching my set up with the RED's.
The only issue of the 70d is not skewing or detail at 2k, but the line skipping shows alassing on background subjects like fence rails that have strong horizontal or vertical lines. That's the beauty of shooting the 4k reds or anything at 2.5k and above, is that alassing disappears.
Granted it's not fair to compare a $900 70d to a $18,000 RED but since 2.5 k would not be much of a leap it doesn't make any sense that they don't use more of the sensor to cut down on alassing.
Given all of this, I find mirrorless to be in the early stages. The olympus em-1 is probably one of the finest cameras I've ever used and has a wonderful feel in the hand, beautiful stabilization, awful track focusing and no controls over the video settings.
The gh3 is good with track focus in stills and video, but anything over 800 iso is a snow storm, plus the fact that the lenses really need to be f1.2 at maximum to get a cinematic focus throw.
I really don't think mirrorless is at the professional level yet though the possibilities are there.
If only you could combine the attributes of all the cameras you'd have something special.
The build quality, tactile feel and in body stabilization of the olympus, the track focus of the panasonic gh3/4, the high iso of the Sony a7s, the menu and ease of use of the 70d along with an apsc sensor.
That and good preamps, a touch screen lcd , . . even a port to add a second larger lcd with all functions would be great for a second assistant to hold and perform touch screen focus while you worked.
Personally I think on a professional level, Canon is deeply in the game. The 70d is lightweight and the video intercuts well with the RED footage, the stills are more than acceptable or professional work.
Canon lens lineup is huge and you can find and buy or rent Canon lenses anyplace in the world.
My only complaint with Canon is I would like them to employ the dual pixel setup on a camera with 2.5 to 4k in a super 35mm or apsc format, to kill the alassing.
The 1dc for it's feature set is too high priced, the c series get's into RED territory to go to 4k, but given that Canon's lineup and user base is so large, that I don't think any smaller 4/3 is going to greatly effect them.
The interesting thing is our 4'3 camera case and Canon case weigh virtually the same, as both are identical think tanks. Sure the Canons are larger but as I mentioned fully kitted out, not that much difference.
The only issue I have with Canons of all stripes is the manual focus lens rotation. My brain is hardwired for Nikon and I can pick up a ZF lens and manually track focus immediately, with the Canons I always have to do a run through.
The one thing I've known since digital replaced film was if I could only carry one case, stills and motion, there is nothing in our portfolio I couldn't shoot with our Canons. The 1dx autofocus in stills, especially tracking borders on amazing, the fact that a 5d2/3 or 1dx can shoot video in a pinch is just an added bonus.
IMO
