Canon EOS R vs Nikon Z6 & Z7 vs Sony a7R III



Nikon is known to have better resoution than sony and canon while Sony is know to have less weight than Nikon an canon and its also smaller in size and physical appearance one can easily call SONY a pocket camera.... dont mind me njust joking but SONY appears to be smaller than NIKON and CANON.....
Autofocus: Canon overcomes all at it's focus point cause it is 10 times the focus point of NIKON and CANON.
For video my guess is Nikon but CANON may up video specs on pro level cameras..
For burst shooting SONY recommended...and sony has a stronger battery life ....








READY GO!


Camera challenge and competition never really cease, they just get more and more involved as camera revolution and evolution continues. In full-frame mirrorless interchangeable lens cameras (ILCs), Sony came out early with a fantastic line of cameras, including the Sony a7R III with great performance and potential.


Many photographers wondered when the other major players in the full-frame 35mm camera format would create competition. Well, it’s happened. Nikon recently announcedtwo new cameras with a new lens mount, the Z series of cameras. The Z6 and Z7, with the Nikon Z7 being the top of the line so far.


And now, Canon has just announced their own full-frame mirrorless camera line, the Canon EOS R. The first from Canon comes in as what many will see as a consumer level model. What else Canon will release remains to be seen.
Let’s Compare What We Have:











Resolution


Both Nikon and Sony use back-illuminated sensors, with the Z7 having 45.7MP compared to the a7R III with 42.2MP. If you are looking at the pixels, the Z7 is very much the same as the Nikon D850 DSLR.


The Canon EOS R looks to be coming in with a 30.3MP sensor, so it should prove to be more of a competitor with the $1999 Nikon Z6 (24.5MP) than the Nikon Z7 or Sony a7R III. Some may consider this Canon full-frame mirrorless to be most closely matching their EOS 5D Mark IV
Size and Weight


With regards to weight, all three are nearly the same with the a7R III coming in at 657 grams (1.44lbs), the Z7 at 675 grams (1.48lbs), and the EOS R at 660 grams (1.45lbs).


The body on the Sony is smaller (126.9 x 73.7 x 95.6mm) vs the Z7 (134 x 67.5 x 100.5mm) and the EOS R (135.8 x 98.3 x 84.4 mm), but the Nikon and Canon both have larger hand grips. Larger grips are nice to see because the Sony seems somewhat awkward at times with larger lenses attached.
Burst Shooting


The Sony a7R III comes offers 10fps, beating the Nikon Z7 at 9fps and Canon EOS R at 8fps. The lower resolution Nikon Z6 has 12fps.
ISO Range


Very slight edge to Canon on this one at 100-40,000 (50-102,400 extended) compared to the Nikon at 64-25,600 (32-102,400 extended). Sony is second to Canon with ISO topping out at 32,000 (50-102,400 extended).


One thing we sometimes forget to look at is the lowest ISO. Nikon has ISO 64, 32 extended. Reminds me of the low ASA of early Kodachrome and Pan-X. Yes, I’m old.
Autofocus


Okay, this is the really big difference that Canon has over both Nikon and Sony. 5655 focus points! How that will actually work in real life remains to be seen, but rumor sites have the EOS R being well received by early testers.


Canons have always been absolute beasts where AF is concerned, ever since the first EOS 650 and 620 35m cameras came out in the 1980s.


Concerning Nikon and Sony, while both cameras boast hybrid on the chip phase detection and contrast AF, the Nikon Z7 has 493 phase detection AF points and Sony’s a7R III has 399 phase detection points.


One key point to remember is that Sony has the Eye-AF feature, which many portrait and event photographers love for its eye detection. Canon and Nikon mirrorless are lacking this feature.
Electronic Viewfinder (EVF)


Pretty much tied here. A high-end or pro mirrorless camera better have a good one. All three of these have close to the same magnification. Hard to spot much of a difference.
4K Video


You can shoot UHD 4K video on all three, but the Z7 has a nifty new feature.


The Nikon shoots UHD 4K in full-frame area or DX crop area at 30p, 25p, or 24p frame rates. It can do 1080 HD at 120p for slow motion as well. The Z7 adds a fun new-lapse movies in both 4K and 8K, up to a total of 9,999 frames.


The Sony and Canon specs are very close to each other and to the Nikon, which some early commenters on social media have seen as a minus mark for the Canon. Canon is definitely one of the leaders in DSLR video, but this new mirrorless of theirs seems to be aiming at higher end, but definitely non-professional, photographers. Will users see much of a difference? I’m sure some will.


Canon and Sony both have full lines of extremely high-end professional video cameras with specs that are absolutely insane. Perhaps Canon is holding back video specs from non-professional level cameras, for whatever reasons they have.
Storage / Memory Cards


The Nikon Z7 and Z6 use a single XQD card slot. XQD is an extremely fast, very high-capacity storage format currently only manufactured by Sony and soon by Nikon as well.


For now, Sony will continue to use dual SD cards for the a7 line, but many of us think that is going to change. There are rumors that Nikon may be able to support the CFexpress in the future with new cameras and firmware updates for current cameras.


The Canon mirrorless uses one, yes ONE! SD card. SD is a fine format of card, but putting SD cards into the EOS R pretty much tells us where Canon is anticipating this new camera to land. Firmly in higher-end consumer, possibly prosumer, level.
Battery Performance


The Nikon Z7 and Z6 can share the same battery at as the Nikon D850, but a slightly newer version has been released labeled the EN-EL15b. The charge lasts for only 330 exposures, which is significantly lower than the Sony a7R III estimate of 530 exposures per battery charge.


Canon EOS R comes in right in between the two at the 430 shot range. It also depends on what viewing and shooting modes one is in, but there will probably be auxiliary battery packs coming soon for Nikon and Canon.

Lenses


Sony obviously has a full line of lenses already available, and many high-quality third-party offerings come to market all the time.


Nikon has the new Z mount lenses, a select few announced with the cameras. Importantly to many, Nikon also made the FtZ adapter to let literally scores of F mount Nikon brand lenses be used on the new Z series. Obviously, there are also many third-party lenses for Nikon F mount that have been made in the last 60 years or so.


Canon has announced some cool new lenses for the R mirrorless, including a compact lens and an awesome 28-70 f/2.0! There is also an EF to R adapter – three actually. One of them appears to have a focusing ring, another with a drop in filter slot, and a basic one. Status of M to R or FD to R adapters aren’t known. If I go back to 1959, I suppose I could wonder about an R to R adapter.


Will there be third-party lenses for Nikon Z or Canon R mounts? It depends on whether the two camera brands release the mount secrets or if third-party designers have to reverse engineer the compatibilities. If the past bears on the future, we will see some third-party lenses, but maybe not any time soon.
This War Will Have Good Results


In the camera market, competition has always been a good thing. As brands jockey for position, the users end up with more and better features and higher quality.


It has happened before. Nikon and Canon battled it out in previous decades with their 35mm film cameras, both professional and consumer models. Other brands such as Minolta, Pentax, and Olympus also created spectacular camera models and systems, several with innovations that are still standards for cameras today.


From those earlier brand competitions came such features and improvements as ergonomic design, off the film plane through the lens flash metering, multi-zone metering, high-speed shutters, and fast, accurate autofocus.


In the full-frame digital camera market, we have had Sony, Nikon, Canon, Pentax, Leica all making great cameras for some time. Now, several of the brands are in the full-frame mirrorless battle. Will another manufacturer join soon? Perhaps. I love reading the rumor websites. A full-frame surprise entry may come from Panasonic.


What this all should mean for the photographer as a consumer is that innovation and refinements will keep on coming. In the battle of the camera brands, the winners are us. It’s a very good time to be a photographer.
