I did finally edit a first version of the SA video.

Canon R5c, DJI RS3 Pro, RF 70-200 2.8, RF 100-500, RF 400 2.8, EF 24-70 2.8. All shoot 8K RAW 50fps other than the Cheetahs running that are at 4k 100fps.
 
 

25 fps, only lens IS, lens Canon RF 400 2.8 IS (rented). I don't use EIS as I'm RAW only other than when I need 120fps that I need to use 10bit log. 

On long lenses 70-200, 100-500 and 400 in my experience IS works better than IS+IBIS, and as you cannot turn off IBIS and keep IS on the R5 I always use the R5c for long lens work especially handled. 

Only the leopard at iso 16'000 has NR applied, mostly chroma noise reduction. All the others have zero NR applied. 

RAW is more noisy and rightly so as most camera apply NR to 10bit Log, RAW should have none (I think a bit is there anyway but not sure). Imo this is great as you can fine tune the NR that you need, you can even go fancy and apply NR to only specific area or color range. 
If you open a R5 RAW picture in LR you will see that by default it apply color noise reduction, so some NR on RAW is needed even for photos. Although imo a well exposed ISO 800 (base iso) RAW video does not need any NR.

Not knowing the settings and what was done in post out of the RAW of the video that you posted is impossible to judge imo.

In general I find it better to expose to the right with Canon RAW and lower the black in post than raising the shadow.    
 

OIS is always on and it helps on the gimbal with the mini vibration of the jeep
One more with a more complex movement with the jeep this one with pre-focusd and then AF locked, 8K 50 RAW 1/100 slow down  2x, gimbal 70-200 
 
 

I was also very surprised how well it managed this tricky situation. Overall AF is quite reliable but is not always perfect. This is example when it lost it in the easiest phase but the condition where really challenging.

R5c 8K RAW 1/50 ISO 16'000 (yes not a typo ISO 16k) 400mm 2.8, AF tracking, on a bean bag, it was basically night and my driver did not believe I could film in that light. The beginning is out of focus until I could select the young leopard face, at 0.19 is when the camera loses him. 
 

Digital IS is available in all modes other than RAW. 8k 50/60 is RAW only. 8k 24-30 MP4 supports Digital IS, 4k 100/120 also.

One simpler scenario for AF, R5c on gimbal handheld on the vehicle moving, 70-200 at 2.8, 8K RAW 50fps slowed down 2x.  
 
 

25 fps, only lens IS, lens Canon RF 400 2.8 IS (rented). I don't use EIS as I'm RAW only other than when I need 120fps that I need to use 10bit log.

R5c RF 100-500 handled, Center area AF (large) max speed and responsiveness, 4k 100 fps (conformed to 25fps), Log3, unedited just Canon LUT applied.

I used in mine on snow, rain and Africa outside on a jeep in a very sandy  environment never had any issue.
The battery I fully agree is pita. 

Did a shoot with my friend today.. yeah the R5C is perm fixed to the tripod lol.
Originally he was thinking of using R5C for mobile and C70 on tripod, but the usability of C70 is just make it much better overall.  I had the same feeling too.
I guess spec on paper is one thing and overall user experience is another, if you use camera everyday then usability wins hands down as you will want to use the camera that in sync with you than try to fight you each time.
 

R5 and R5c have exactly the same weather sealing and same rating.

around 15ms same as 24-30p, 8ms 120p
 
the above chart is misleading as it seems for photo not video, r3 is 9.9 in ff 24-60

I used the R5c with the full cage and the FxLion One Battery on top of the cage on a Ronin S quite a bit and depending on the lens is a bit at the limit with the clearance. The EVF of the R5c is stick out quite a bit and the cage need some more space on the motor side.

Sold the S and now I use a RS3 Pro and due to stronger motors and longer harms I can mount whatever with no issue. For my Africa project I did use a lot with the 70-200 and no problem at all to balance and still have enough clearance to go underslung.

Although Smallrig claims the cage to be compatible with the DJI arca plate ,mine is not and I tested with RSC2 (too small for this camera anyway) and RS3 Pro plates and due to the security pin both cannot take the cage directly. I have the R5 full cage so maybe.
Bottomline either you mount the DJI arca adapter (that comes with the gimbal) on the tripod hole of the cage or if you want something more solid you need to buy this: SMALLRIG Quick Release Plate for Arca-Type Standard Compatible with DJI RS 2 / RSC 2 / RS 3 / RS 3 Pro Gimbal - 3154  or this SMALLRIG Camera Quick Release Plate Adapter with Arca-Swiss for DJI RS 2/RSC 2/RS 3/RS 3 Pro & for Ronin-S Gimbal - 3061.

I use the gimbal on high vibration environment quite a bit, on MTB, Motorbike, Jeep, Skii, Heli so the stronger motor of the RS3 Pro is a no brainer for my usage. For only 200g more is imo worth. The new auto locking of the RS3 and RS3 Pro seems a small thing but it makes life so much easier.

R5 and R5c have the same weather resistance.  Both not at the same level as 1Dx.
Used my R5 and R5c in sandy, light raining and light snow with no issue so far but they are insured so I take more risks without worrying. 

Is not a picture is a frame grab at 1/100 from 50fps video...... is normal that is soft as there is motion blur....... it was to demonstrate AF at 2.8 while an animal sprinting at 50+ mph.....

This is a picture at 1/1600

I have one button to cycle through the AF frame, one to enable / disable face tracking, one to pause AF while pressing, and one as suggested above to toggle AF on/off.

One thing that I find super useful is peaking with AF..... on the R5 peaking does not work while in AF but on the R5c it works and I find a realy life saver as even is super bright sun or strange angle on the LCD I can always monitor if the AF is spot on or not. 

 Cheetah hunting R5c 8k 50, 1/100, F2.8 400mm with AF

From the official spec it was always clear that 8K 50/60 works with internal battery only without AF and IS, with external power AF IS works as normal including EF lenses.
If I recall correctly that Gordon got it working on internal battery 8k 50p (not 60) with AF and IS but it was a pre release camera. This could even be lens dependent as I can imagine that you need less power for a 35 1.8 IS than for a 400 2.8 IS lens or could be that the final firmware simply does not allow it anymore as it may not be reliable. 

So I did many test and the face tracking the R5c thanks to the Face Only mode is more reliable/usable for video than the R5. I did shoot a school theater (not my usual stuff) and with a 70-200 at 2.8 with even changing lights etc the Face AF worked almost perfectly and when it loses the Face the fact that it does not jump focus it does not ruin the shoot.






In pure speed R5 and R5c with the AF settings to the max speed/reactive they are exactly the same, I tested side by side with the same lens.
Now here is where my problem was the "large AF area" of the R5c is similar to the second smaller AF area of the R5 the one that I use the most for action and it turns out that R5c tend to stick to the BG and not refocus on the subject but surprisingly when using the smaller AF area the R5c works like the R5 in the second smaller area. Bottomline this seems to fix my issue.

Still it would be cool to have R5 AF engine animal, vehicle and all the other AF area at disposal but with this setup it seems to work for my stuff as I normal use either Face or the small area AF. 










Bottomline the camera is growing on me, but it could be just amazing if they would really share more between the two systems.
 
 

Really not sure why you cannot do it with an EVF..... but people are different so fair enough. Then you should buy a used 1Dx III until you find one. 

I'm still a bit puzzled as is mentioned the strobe example, where you are in single shoot mode so in the right settings R3 and R5 both runs at 120 fps refresh, now the R3 can maintain this even at 30 fps making is blackout free but the lag is the same so in a single shoot there are no difference.
Btw there is another lag that is a shutter lag that is a different story, and this is 83ms in machinal and 50ms in ES for the R5, 5IV is 58ms (plus 86ms blackout) and R3 is 20ms in ES.

Some more examples where timing is key with strobes but if you do it a lot you will notice as your brain will start to anticipate the "lag"

At this point cinematic = is not a still picture 😂😂 

I mean the R5C is a cinema camera and has all those things if you include the ND adapter and Tascam shoe mount. But I agree, 'small' is subjective. Personally I appreciate the R5C for giving you the option to build it up to about the size/weight of a 1DX line cam or strip it down to essentially an R5.

At the moment it seems a huge list 🙂: https://cam.start.canon/en/H001/supplement_0160.html
