Artistic Foto & Video says:

But Canon R have 480bitrate, A7R III 1000 bitrate. Canon R have 10bit c log mod, A7R III 8bit. But the big problem is that crop in 4K witf Canon R.

Kai S says:

Why are you comparing these to the A7Riii not the similar level which is A7iii ??? The sony has the best dynamic range I dont know what you doing with your testing lol.You guys have the worst test I have ever seen

Ravencroft says:

Great review. Bought the Eos R for the stills and the future proof mount. Bodies come and go, lenses stay.

8mal100roller says:

How many hours are between these photos at 1:21 ? What kind of a test is this?

Sergio Serra says:

The lens on the Canon is on another level though

Sameer Sheikh says:

Very much partial review. 👎
Only Nikon used with adaptor and the rest of them uses native lenses.
I saw first time on this channel Eos R better than Nikon z7 in every aspect. Thats very very partial.
Nikon Z7 has better ability
Check out Max Yuvrev review. U will know very well
Thumbs down for this video.👎
U both Canon Guys…👎👎

Spec 7-9D says:

Two high resolution camera against a lower resolution and a broken nikon exemplar. Why did you even publish this test? Not really reliable is it?

Richard Cai says:

Incompetent and near pointless comparison. Back to the drawing board.

Satya Buddhavarapu says:

You folks are bad photographers. Wow, and this is really bad testing. I guess you folks should stop doing these tests. Also guys, this video is just so biased. Its darn obvious from every statement you say. The XQD really.. Its what Nikon has gone for. The future is CF Express. Thats the best decision they took. Imagine using a slow SD card on a camera that shoots > 42 mp raw images. The buffer can never take that load. Isn’t that the problem with the R3. Also you had a poor selection of lenses. Couldn’t you even use native lenses. Please compare apples to apples. Oh btw- Canon EOS R has lower resolution than both the other cameras. Btw- its not the camera. Its the photographer’s problem. Haven’t you heard- Nikon Z7 is an unforgiving camera that can provide amazing stills, provided the photographer is worth it. Same goes with R3. The video test – Another disaster.
Btw- i shoot with both Sony a73 and Nikon d850 and just recently bought the z6 for video. Thats doesn’t mean i am against Canon. It has its own strengths. All my friends shoot Canon and they love their cameras.

For the public- go with which ever camera you like. Do not make a decision based on videos like these. Make it based on your current gear and what goes best with it. This is Falsified and biased information.

Saud Kazi says:

This review is [email protected]#*d up on so many level, I don’t even know where to begin. Why would you waste your loyal viewers time to review camera if you know from beginning that one of the camera is not performing right. Just to get a click?
It not even fair comparison on many level… it would be fair to compare with Nikon Z6 with native lens…not an old 50 mm lens.
Please study each camera & it’s features before you put your next review. Thank you!

Marko Nara says:

Im impressed by canon…. no one saw that coming…

willie cheng says:

Very useful comparison. Do you have a test with Leica Q?

CARLOS B says:

I have not read all the comments but I guess I am not the only one commenting on the validity of this test. I am not sure how you can compare the Canon vs Sony/Nikon. The Canon has almost 50% less megapixels than its counterparts, therefore it seats in another league. It would have been more accurate to compare against A7III and Z6. This has a lot to do with the results you got, specially on dynamic range department. I do like to watch your videos but sometimes just throwing something to get views might actually hurt than benefit your channel.

Luke Caldwell says:

Did anyone bother to use the cameras with external recorders? 4K 4:2:2 instead of 4:2:0 and especially in a record format like ProRes would have been a better test of video.

Stefano Menegus says:

Of course, Canon is doing better in ISO test. I mean: it's 30 mpx vs 42/46. Different size of the pixels on the sensor. They're not comparable.

Geoffrey Byers says:

How can you do a test with a malfunctioning camera? YouTube I guess. Furthermore your testing protocols are very lax. If you compare noise between sensors you have to standardise the image size first.

Sevak Dilanchian says:

Enjoyed the video but as some others have said, you should be comparing the EOS-R to the A7III and Z6

Aperture says:

Who would of thought that Sony with pretty much no camera experience, heritage and prestige can compete with the big dogs like Canon and Nikon with decades worth of experience and loyal users, but here we are today and Sony is coming very close.

branislavpetkovic says:

Stopped watching this BS at 4:55 cos Canon felt apart already at +/-2 with much lower sensor resolution. Much better non-Canon biased comparison is A73 vs Z6 vs R.

muviewsic says:

LENS CHOICE! Huge bias comparison. How much money Canon pay you? You use native mount Pro lens for Canon and Sony, and you choose a low end kit non-native lens for Nikon. Other problems also prevail in the video.

Stefanie Daniella says:

Canon EOS R FF ExpSimLV AF 30mp (60mdp: Mega-Dual-Pixel) 1:1 straight read 4k uhd @ max 480Mbps video image data rate
(hint: folks, use the right lens for best IQ):
▪why use a 50mm FL to shoot 1.75x 4k uhd, when a superb 28mm F2 FL is available precisely for 1.75x "best 1:1 straight read 4k uhd 50mm FF FoV"!? (if one wishes to compare 4k uhd 87.5mm F1.2 FF FoV with the 50/1.2, then obviously, the subject scene is very different)
▪yes, folks, serious Cinematographers think exactly that way (all EOS Cinema cameras have their unique "crop")
▪(not "videographers" stuck with "whatever lens they got"): who whine about "crop"
EOS R ExpSimLV AF works fine (live exposure preview effects: ON or OFF) = simulates "aperture exposure effect" f1 to f90 using optimal f-proprietary for AF, no matter what. ExpSimLV APERTURE SIMULATION does not need to restrict itself to "either wide-open or aperture stop-down only" as chosen by user for LV AF.
Canon ExpSimLV arrived in EOS LV dSLRs in 2005, and it revolutionized WYSIWYG-LV and Optimal f-value AF "simultaneously" (together).

Sony A7RIII 42mp (Aperture Stop-Down (ASD) type WYSIWYG-LV Only):
Sony's LV AF works better with Live View Display: (Camera Exposure) Setting Effect = OFF (= No WYSIWYG Live-View)
A7RIII/A9/A7III: Max video 100Mbps image data rate
Most of Sony's video 100Mbps is wasted on excessive downsizing oversampling "full-sensor-width" 7.7k A7RIII (or 6k on A7III/A9) down to 3.84k or 1.92k (Superior 1:1 straight read "crop" is UNAVAILABLE; except 1.2x on A9 3.84k24p 100Mbps): 100Mbps simply cannot convey enough color data for grading in post without falling apart.
Any 1.5x crop mode video is unfortunately only downsizing oversampling "crop sensor width", and not true superior 1:1 straight read video.

Nikon Z7 45.7mp (Aperture Stop-Down (ASD) type WYSIWYG-LV Only):
Nikon's LV AF works better with with "d8" option (Apply Settings to Live View) = OFF (= No WYSIWYG Live-View)
Nikon Z's will vary megapixels depending on degree of lens distortion, as it has a built-in Auto-Distortion Control ADC (=forced):
so this comparison with new Nikkor Z 24-70mm F4 S (suffers high distortion) is "unfair", because the ADC "correction" is so drastic
▪on a Z7, uses a tighter subcrop as low as 40.1mp out of FF 45.7mp, and re-inflates it up to 45.44mp for "live-view corrected"
▪on a Z6, uses a tighter subcrop as low as 20.1mp out of FF 24.5mp, and re-inflates it up to 24.34mp for "live-view corrected"
thus, for either Z7 or Z6, using a new Nikkor Z 50mm S prime (negligible lens distortion) would result in less severe ADC "correction" (=less extreme subcrop; more original resolution used; and minimal re-inflation; and less ugly digital artefacts) and offer better IQ (for fair comparison, where higher mp should offer more resolution). heavily corrected, subcrop, and re-stretched images should not be used.
Z7+Z6: Max video 144Mbps image data rate
Most of Nikon's video 144Mbps is also wasted on excessive downsizing oversampling "full-sensor-width" 8.29k Z7 (or 6k on Z6) down to 3.84k or 1.92k (Superior 1:1 straight read "crop" is UNAVAILABLE, period): 144Mbps also simply cannot convey enough color data for grading in post without falling apart. Any 1.5x crop mode video is unfortunately only downsizing oversampling "crop sensor width", and not true superior 1:1 straight read video.

ASD-WYSIWYG-LV: Aperture Stop-Down type WYSIWYG-LV, is the kind of LV already available on Canon Powershots back in 1999/2000, which was derived from Canon (analog + digital) prosumer videocamera technology (=mirrorless interchangeable lens+mount + EOS (AF EOS SLR based) Lenses) long before that.
… Sony had videocams, too … but back then, they lacked extensive interchangeable mounts + AF Lenses like Canon.
Either way, ASD-WYSIWYG-LV has limitations for AF for stills, because it was meant originally for ASD mode video, as it lacks optimal f-apertures during simultaneous "WYSIWYG-LV" of "simulated f1-f90" chosen by stills shooters.

Imagine the absurdity of buying into a live-view oriented camera with EVF and WYSIWYG-LV capabilities, only to discover AF works horrible with ONLY ASD type WYSIWYG-LV!? (Sony+Nikon+other non-canons, face this predicament) … and turning ASD-WYSIWYG-LV OFF just for "better AF"!?

Canon has ExpSimLV AF for WYSIWYG-LV for stills, with no ASD-WYSIWYG-LV restrictions typical of ASD mode of video AF.

Mike Derbish says:

Good job on this one guys! Thanks!

Steve Miller says:

Let me preface my response. I have used the 5D III and IV and the EOS R, I have used the Z7 and I have used the A7R III so none of these cameras or their capabilities are at all foreign to me.

The stated results do not at all reflect my and others real world testing. The dynamic range of the Canon is significantly less than the Sony and Nikon for both underexposure and overexposure.

The Canon sensor is not ISO invariant and when underexposed it suffers from significantly more false color noise, and more luminance noise compared to the Z7 or A7R III. I believe you have switched the files or or perhaps shot the cameras in 12 bit to limit the Sony and Nikon's dynamic range. I can provide examples of side by side shots at base ISO and higher ISO if necessary to back up my findings. DPreview's studio comparison tool will show this too.

Why show out of camera jpegs you throw away 60% or more the detail the camera captured? Who would buy these to see what jpegs can do?

For the tracking comparison why penalize the sony and not use eye AF? This is the most consistent way to focus on a moving person and the A7R III attains an even better hit rate than the 5/6 you got.

Why put the very best RF 50 1.2 on the Canon and 85 1.4 GM on the Sony but use an adapted F mount 50 1.4 Nikon Lens the new Z mount 50 1.8 is better?

For high ISO the canon is not the "cleanest by far" the Sony is significantly cleaner as a processed 14 bit raw file, the Z7 although not as good as the D850 is still better than the EOS R. How did you obtain a result where the Canon is the cleanest by far?

Can you please make the original files available for all of us to download to see the comparisons ourselves?

Richard Reed says:

Why continue with the test after admitting issues with one of the cameras??? This should really be re-done.

kaczorefx says:

I don't mind the comparison even though you seem to have reached a result that is opposite to all other sites and comparisons. My problem with this video is that most of the photos you showed from the Z7 are practically unusable for any professional. In some of these situations a smart phone photo would look better. You are literally the only source I've seen that got these results from this camera. People are complaining about banding when compared to d850, people say the AF could be better especially compared to nikons own 3D focus mode, but I don't think I've ever heard anyone saying the the contrast /dynamic range in this camera is anything less then superb. And here you come, get these results and just post them. Did you consult them with other reviewers? I'd be scared sh&#@less to publish these results because there is something seriously fishy about them. I can't stress enough, you are probably the only source that shows the Z7 performing this bad and this fact alone puts your reliability in question 🤔

Mark Davidson says:

Thanks for this real world evaluation. 
Too frequently we rely on the "popular wisdom" of specifications, charts and invested opinion that can lead us down the garden path. The real fact is that all these cameras are excellent tools (the Nikon AF woes notwithstanding) and will make their respective owners happy.
As a Canon owner I was surprised by the Canon performance proving that I had subscribed to the narrative of Canon weakness in IQ. This despite the fact that the only shortcomings in my work with my Canons have come from user error/foolishness and impossibly lit scenes.

Milan Dzunda says:

Very happy with my A7R3. Don't think my images would be any better or worse if i had used R or Z7 instead. The only real benefit of Sony is that R or Z7 currently offer natively only 3 lenses which is not great.

Daniel Camacho says:

Isn't the Nikon native lens made for the mirrorless cameras have a 1.8 apperture? So even if the mount does allow more light in would it still be comparable to a lens at an apperture of 1.4?
