Good morning
I am passionate and I wanted advice from the most experienced
I have a Canon 6d and I wanted to switch to the SONY A7R3 or the Canon 5d mark IV
I'm interested only in quality image
Someone can help me
 
How is your 6D limiting you? What lenses do you currently have?
 
In image quality, DPReview says the Sony is better.

Mark,

I love shooting with my Canon and I wouldn't trade it for a Sony. But if all he wants to know is image quality, then that particular Sony camera beats that particular Canon. I don't know why someone would select a camera based on a single attribute, but that's what he wanted to know.
 
Comparing the bodies only the Sony will have better IQ, but IQ depends on lenses as well as bodies. If you can't afford the latest GM lenses for the Sony then the Canon may be capable of equal or better image quality within the constraints of your budget.

But a lot of factors go into a quality image.

On a gear side, quality of the image will be decided by the camera AND the lens.

On the photographer side, the quality will go mostly to the skill of the photographer.... and straight out image quality will depend on focus. If an image is out of focus, the quality is going to stink.

So on a purely technical level, the Sony A7riii has greater resolution than the Canon models, as well as better dynamic range and other technical factors. So looking purely at camera sensors, the A7riii "wins" for image quality.

But that's only a fraction of the equation. Next question is what lens would you be using on each camera.

I think laypeople incorrectly throw around terms like image quality. From a scientific standpoint, the Sony is capable of higher image quality than Canon... in the sense of more dynamic range. In the sense of the A7riii having more resolution than a Canon.

But I think many lay people confuse technical image quality just with "which camera will make my photos look better"

And the reality is, except for slightly different color handling, a Canon photo will look nearly identical to a Sony photo and nearly identical to a Nikon photo.

I see beginners say things like, "a lot of my photos are blurry when I try to take pictures of people moving, which camera will fix that?" I've see, "my $100 point and shoot takes great pictures during the daytime, but when the light is low, the pictures are all grainy... which $100 point and shoot will be better for that?"

No. I’m assuming you are referring to which has the best image quality but the problem lies in that image quality is 100% subjective.

I have friends who shoot Canon and some of them shoot weddings and say that Canon produces the most pleasing skin tones. Therefore Canon must best. I have other friends that shoot NIkon who also do event photography that appreciate the great vivid colors colors and dead accurate Metering system. So maybe NIkon is really the best.

In reality there is no such thing as best. Only things with compromises that can still be good enough for what you do. But what concerns me is it sounds like you want the best but haven’t mentioned two things vastly more important than Camera A or Camera B.

I’d focus more on mastering composition and lighting then master editing. After that simply pick the system that has the lenses you need and the specific camera features you also need. Worry less about Camera A vs Camera B.

Hands down, the A7R3 will deliver higher IQ than the 5D4. The questions you need to answer for yourself are:
  • Will anyone notice the differences in IQ?
  • Given that there is a noticeable difference in IQ, will anyone care? That is, will whatever differences in IQ that there may be make a difference in the "success" of your photos?
  • Given that all the above is satisfied, are the differences worth the differences in price between the systems?
  • Lastly, will you enjoy using the A7R3 as much as the 6D or 5D4? You may enjoy it a lot more, but it's something worth considering.
Money no object, I'd definitely get the A7R3. In fact, on paper, that has everything I want in a camera.

Many times folks think that their smartphone takes better photos than their DSLR or Mirrorless cameras. Very often it turns out that the smartphone, by default, adds more sharpness, contrast, and saturation than the more advanced cameras. Of course, those cameras have adjustable settings for these, but advanced cameras are so overwhelming that it's understandable that beginners wouldn't even know where to start.

And then there are eager beginners who think that they must change every camera setting, and then get overwhelmed by the process, and may even end up making a mess of their images.

Hello!
Thanks for the reply !
The first thing I have lenses Canon 24-70 f2.8 L II and 70-300 L + Sigma 85mm art (I take it by reading the reviews and I'm overcooked)
But everyone considers the Sigma 85mm art as one of the most performing lenses but I read the comparisons and the best reflexes give a completely different vote ..... that is, the fortographic machine centers a lot and my question is in that sense
The dxomark evaluates with a score of 100 the new Sony A7R3 which is the maximum score but I pre-order the manual and the complex system
Thank you

Canon lenses work well on the Sony with the right adapter.

Of course there are other considerations when purchasing a camera other than sharpness. But if image quality is your only concern and would like to stick with Canon, then the 5DSR is your answer. Since you like DXO Mark, the Sony 24-70 f2.8 on the A7R2 (they do not have the A7R3) gives you a shaprness score of 28. (It should be roughly the same with the R3) The canon 24-70 f2.8 gives you a sharpness score of 32 on the 5DSR. On the other hand, the 5DSR lacks many other features.

The scores wouldn’t be roughly the same as the maximum sharpness score for the a7rii is 42 (it’s a measure of perceptual megapixels... which maxes out at 42 on the Sony) vs 50 for the Canon 5dsr.

So the Sony is getting 28/42 — or 67%

The Canon is getting 32/50— or 64%

The Sony is actually doing modestly better at maximizing the sensor with 24-70 lens.

Of course, the Canon is ultimately getting slightly more resolution with that combination. And resolution is one aspect of image quality. But the Sony is greatly exceeding the 5dsr in dynamic range, ISO performance and the other aspects of pure IQ.

There are several reasons the 5dsr doesn’t generate the positive reviews and buzz of the D850 and A7riii despite having even more resolution.

Unfortunately, it's an open-ended scale; 100 is not the maximum. There are Hasselblad and Pentax medium format cameras which both have scores that exceed 100.

But understand that there is a lot more to technical image quality than the few metrics that DxOMark reports, including your own technique, and technical image quality may have little to do with what makes a good overall image.

Also, some cameras are simply more pleasant to use than others, are more reliable, require less fussing with, and are better supported by the manufacturer.

I don’t think it’s a good idea to buy a $3,000 USD camera based on only one score. Personally, I love shooting with the 5D.

Think of it like this: Van Gogh sometimes painted with a putty knife. Ansel Adams almost never shot color. Your camera let’s you make art. There’s more to the art than noise levels. I love Canon ergonomics. Many love the skin tones of Canon. And their professional support is fantastic.

I’m not trying to make your decision, but I think you should hold these two cameras first.
