5DS scores at DXO **now posted**
- Thread starter ahsanford

I totally missed this in the DXO writeup:
"What’s more, our industry standard tests have shown these are the best sensor results yet for a Canon chip, with the 5DS cameras offering a small step up for image quality against other full-frame semi-pro models such as the EOS 6D and EOS 5D Mark III."
I thought that was just a fun/clumsy set-theory dig on the 5D3, but a few clicks later... Wow. See attached.
To DXO: [a kiss to my fingers for the masterpiece move]

Just one question to let me know if I understood DXO Metrics correctly.
1) DXO evaluates separately Lenses [features] and Sensors [features]
2) DXO downnsamples the images captured by each sensors to their "standard" 8MPixels size so, even if our eyes sees more noise-per-pixel in a 100Mpixels image than in a 10Mpixels one, DXO will rank the ISO performance at the same level (provided the inherent technology is the same or "ceteris paribus")
3) So, it seems that DXO evaluates the technology level of the sensor regardless its resolution, even if most of us think that resolution is one of the features of a sensor
4) On the other hand, if a potential customer wants to know from DXO the performance in terms of sharpness of a Lens, the sensor's resolution matters in DXO tests.
I don't care about resolution and I think that a 16 Mpx Full Frame would be more than enough for my needs, but I would like to ask to my fellow CanonRumorsFriends whether my understanding is correct: is it true that DXO Metrics states that a change in a sensor's resolution
1) has no impact the Sensor performance
2) has a positive impact on the Lens + Camera performance?
If so, it could seem a bit misleading.

Dear friend Surapon. The measure "overall score" of DXO Mark is totally random and useless.surapon said:
On the other hand, the following individual measures:
COLOR DEPTH
DYNAMIC RANGE
and LOW-LIGHT ISO
They are useful when comparing cameras with the same type of RAW file, the same processing software, and the same resolution.
According to DXO, the only difference is the performance at high ISO settings, because everything else is a technical draw. I'd rather not have concerns with moiré and aliasing, and choose Canon 5DS when they can add sharpness on the computer but can not totally eliminate the moiré that is already in the image.

Yes and yes.
From DXO: "Sensor Overall Score does not show a camera’s: Resolution, i.e., its ability to render fine details."
And the lens scores are heavily weighted by sensor resolution. The same lens on two different cameras gets very different scores.
This might explain why the EF 70-200 f/2.8L IS II USM is ranked 1,064th of all lenses tested.

DXO tells clearly that one should first pick the resolution needed, and compare only similar models to each other. Otherwise, this test would crash the camera, if one would look only at the score. With 101 points given at max currently to a 19MP camera ;o) -- my favorite one.
However, most of the time my "old" 5dm2 has enough dynamic range for the material I need to shoot. Having said that, two stop more and I would be excited. To lift my exposure only about one stop would eliminate a lot of noise from the start.
My excitement for the 5ds is not broken, but cooled off a little bit, after the test.
As a side note: I enjoy that the Canon has a low ISO range, which is honest. No messed up raw -- not so much as other cameras. The comparison to Sony and Nikon shows clearly that all that "beginner" ISO talk is not a quality talk, which proofs the point I make since long. Nearly 10bit color around the top ISO end, that's not even point and shoot quality.

None, but does it pass the giggle test that the D3300 is a better camera?
Maybe it depends on how you personally define "general-purpose."
Their description of the composite score: "Measures camera performance for a general-purpose use camera based on a combination of three use case scores."
If someone said "grab either a D3300 or a 1DX, but I'm not going to tell you what you're going to be shooting or in what environment," I would personally grab the 1DX, because it would be better in general. For a known case, like I'm shooting portraits in controlled light, I may grab the D3300.
Joe Sixpack's definition of "general-purpose" may differ.
I don't believe cost plays a roll in DxO's scoring.

Well thank God for DxO. All this time I was falsely laboring under the assumption my 5D Mk III was a full professional grade camera. Now I know the D810 assuredly is and my 5D III assuredly is NOT. Thanks to DxO crew for clearing that up. (See? It's not anger. We're laughing at them. That's all)

I really wish there was a way to unsubscribe from a thread you've participated in. The only way to stop getting notified when a thread drops off the cliff is to delete all your posts...which is annoying.

Nope. Although it varies by geography, Canon Europe lists the 5-series as "EOS dSLRs for Professionals" (and last I checked, DxO is in France and France is in Europe).

Canon USA doesn't categorize the bodies, and at Canon Australia only the 1D X is listed as Professional.

Weird, I never get any notifications unless I click notify at the bottom. Is unnotify not working?

Hmmn, you appear correct. I could swear I remember seeing the 5D3 described as semi-professional on Canon's own website (either Canon USA or CPS USA) in the past though.
