5DS scores at DXO **now posted**

[jrista]

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.

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

I mean in the "Snow new replies to your posts" section of the forums. I've got a bunch of threads that keep popping up in there that I just don't want to be notified about anymore...but they just keep cropping up. There is no way to remove a thread from showing up in that list. I never actually subscribe to email notifications for anything, so the notify thing doesn't apply here.

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)

You don't even get a pop up flash on the 5DIII

Pop up flash.....

What a useless feature......

I haven't used that feature since... well.... five minutes ago.....

Bet you weren't using it 'professionally' ;D

Was playing around with DxOs comparison tool, and saw this:

Not terribly surprised, but good god... at least Canon's effort is keeping up with 1" sensors! ;D

Actually Canon USA does, well sort of, classify bodies, actually CPS does. Some bodies count more than others for status points and some bodies can not be included in the list.

Oh, ok. Since the 5DIII, 5Ds and 5DsR are worth more points than the 1DsIII and 1DIV, I guess that makes the 5-series more professional than the 1-series.

I was

easier to use the pop-up than to walk 2K over to the main building and then come back with a "real" flash.....

I suppose I could have used my phone.......

'Phone's the answer. Add a DxO One to it and you won't need a 5Ds :-X

I respect the french for fine inventions like red wine and rectrum love, but DxO is dangerous for photography

That's true for DXO, but is it also true for DXO's partners?

I don't understand the methodology. I remember seeing many people remarking that if the 5DIII had as many megapixels as the Nikon D8xx, it would score similarly, yet the 5DS has more MP and still got a lower score.

So I'm very confused about how they generate their scores.

For lenses, absolutely. Their methodology strongly weights the resolution numbers. Expect to see great L lenses' scores go from ordinary on a 5D3 to stellar on a 5DS with all those pixels. It's the same lens, but in their weird minds, the 'potential of that lens is more fulfilled' on a higher resolving sensor.

(I actually don't mind ranking body+lens performance like that, but then only showing the lens in their summaries with a ranking based on a body+lens test is nuts. A great lens is effectively punished for having the misfortune of being mounted on a lower res body. It's misleading at best.)

For sensors, they claim resolution doesn't drive their ratings.

Of course you are, because it's an undisclosed 'black box' calculation. I have seen some approximations and guesses for their formula:

1) DxOMark_Sensor_Score = 59 + 4.3*(ColorDepth-21.1) + 3.4*(DynamicRange-11.3) + 4.4*log2(ISO/663) -0.2

2) DxOMark_Sensor_Score = 4*(ColorDepth) + 5*(DynamicRange) + 2*log2(ISO) + 2*(SONIKcoeff) – 4*(CANcoeff)

I have my suspicions as to which is closer to the truth.

2) needs new logic to be fully functional.

IF sensor = sony ANDIF body = DXOONE ANDIF filetype = superrawplus, SONIKcoeff=1.8, ELSE SONIKcoeff=1

what about the 1Dx? Top score. Remember I said "sort of", not precise scoring.

In the USA, CPS appears to be a money-making device for Canon. The points seem to correlate best (within a category) with approximate market value, or depreciated original MSRP. No other reason the 5DsR is worth 1 point more than the 5Ds.

I am not saying that the CPS are precise. Only having fun pointing out that CPS is back door, granted not accurate but never-the-less a way that Canon separates cameras and lenses into more vs less valuable.

Looking at bodies produced about the same you get some idea ranking - as you say by price.

Given that it's Canon Professional Services, one could argue that anything on their list constitutes Pro gear, including the 7D and 40/2.8. 8)

I have a bowl of popcorn, a fully charged iPad, a laser pointer, and a kitten.... I'm set for entertainment and waiting for someone to post squirrel pictures with 15 stops of DR.....

This has my vote for best comment yet!

I thought it was random number + 30 points if Nikon and 5 points if Canon ;D

dpreview is not that bad...just lightly sponsored by Nikon

Sure, but didn't they strike a deal to use DXO's data in their reviews?

"World-leading photography website dpreview.com has adopted DxOMark, powered with DxO Analyzer image quality evaluation engine, for its photo gear reviews. This partnership confirms DxOMark's unique position as an independent camera and lens testing laboratory for leading photography press publications and websites."

http://www.dxo.com/us/image-quality-evaluation/partners

I don't know how much that marries them to their results, but it's pretty easy to correlate DPR's sensor scores to DXO's if one wanted to.

[Loswr]

Hmmmm...and DPR reviews are incorporated into Amazon's product pages...because Amazon owns DPR. Manufacturers can certainly offer large retailers whatever terms they choose, with obvious implications for that retailer's profits. I'm sure DPR wants you to think they're impartial...just as DxO wants you to think they're doing good science. I know one of those isn't true, I'm not sure about the other.
