When you put a d600 on the nikon 500,

Also the 600's

I guess the 'tests' kind of back up what was already reported.
The difference looks quite substantial, nikon must be close to updating some of their lenses (400/500/600)

This is why DxOmark sucks:

Although the two lenses are extraordinary performers, the Nikon can’t quite match the new $11,999 triple fluorite Canon in sharpness or in lateral chromatic aberration, however overall the two perform very similarly. Both have homogenous sharpness at maximum aperture and possess low distortion and vignetting and excellent transmission, but reason why the DxOMark scores are the same is due to the excellent noise and dynamic range of the Nikon D800 sensor.

The LENS tied the Canon lens because of the CAMERA used!!! HAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHA.

Well , I just put in the d600 in the comparison to get something which is closer to reflecting the lenses?
But it's indeed funny they tie the lenses due to the sensor behind it outperforming the other sensor


Also when you look at

I wonder how they conclude 24 for the nikon, if you compare it to the sony(also on 24 mp?)
The sony has better t-value, sharpness, lower CA, yet it scores only 22?

There the canon has 19mpix, the nikon 15
0% distortion vs 0.2%
3µm vs 7

I don't know if their tests are really scientific, if so it's easy enough to draw your own conclusions based on their values ( just forget the overall score and compare per lens/body).
And ignore the conclusion of them i guess

Better hold on to those lenses and wait for better bodies , Those cycles are much shorter and less expensive to replace. Imagine what those nikon sensor would be like on the canon lenses!

I guarantee you that and shot I take handholding my 600 II with the 1D X would be sharper than an equivalent shot if I handheld the Nikon 600/4 with the D800.

Ah yes, but that could say more about your physical state than the quality of camera/lens ( sorry hehe )

The 600 IS II , for me at the moment is still something to work hard for and hopefully own in the future !

This comparison of DXO's results is what makes me EXTREMELY SUSPICIOUS of them. The Nikkor 500mm scores 25, when every single trait that factors into that score is worse than the Canon 500mm...which also scores 25. That is just plain wrong. The Canon has zero distortion, higher sharpness, less vignetting, less CA, and the same transmission...on a LOWER RESOLUTION BODY! It should have a higher score than the Nikon.

I have been critical of DxOMark's Scores, but this takes the cake for the BS factor. Even the Sony 500/4 bests the Nikon on every measurement, but the Nikon lens outscores the Sony.

However, while the Canon 500mm mounted on 5D Mark III is sharper optically than the Nikon model mounted on D800, at the light levels used for DxOMark score (1/60, 150 Lux), the excellent dynamic range of the Nikon D800 sensor helps it improve the DxO Mark Score and accounts for the level-pegging.

Sorry, but what the heck does sensor-based DR have to do with scoring a lens?!? Nothing. This smells stinks to high heaven of bias.

At least this time, they have apparently come right out and said that the "DxOMark Score" is utterly meaningless.

Aye! Smells like a beached whale that just deathfarted.

About time they ousted themselves for their insane bias. What a ridiculous joke. It is more than clear that these tests are most definitely not "lens" tests...they are camera tests, and throwing the D800 into the mix with its extremely high resolution sensor completely invalidates any scalar score DXO tries to push as a means of comparing lenses against each other.

If you look at the test results they are measuring the combination of lens and body. Hard to do otherwise. Makes comparison between manufactures difficult and less than meaningful.

Oh, I know. I've long stated that DXO's "lens tests" are really "camera system tests". That doesn't change the fact that lenses can be compared on camera bodies with similar or identical pixel densities in order to provide a more meaningful basis for comparison.

As it stands, in the example above, one can only assume their Nikkor 500mm f/4 lens will score 25 IF used on a D800 body. I know they test against multiple bodies, but usually the spread isn't broad enough to support useful cross-brand comparisons.

Yes, and sorry, but I think you are missing the point. For every measurement, all generated with a body attached, the Canon lens comes out on top, in some cases by a significant margin. Yet, the Score is a tie. So...the score is fabricated, pulled from their nether orifices, etc.

The hidden row (see my attachment) includes a technical parameter which determines the overall score.

So far, this thread's remained relatively mild

My apologies to all animal lovers but the expression "a beached whale that just deathfarted" just got me LOL ;D ;D ;D ... "deathfarted"? LMAO ;D ;D ;D

 

[Rienzphotoz]

I read Nikon rumors every day (coz I also use Nikor gear) and when I read this article two days ago, the first thought that came to my mind was "what a load of chicken 5h!t"

Haha. Sadly, I've had the unpleasant experience...one of the few memories from my childhood that will never go away...when we had a beached whale in California let a big one go.

It can be a lot worse, though! THIS is a Deathfart (timeindex 4:55):

Oh, and for an even worse experience...time index 3:10. I think my favorite quote is 5:35: "It's the whale fart symphony!"

 

[ahab1372]

And then there is the story of the guy who wanted to remove a beached whale from the beach by blowing it up ...

 

[dtaylor]

Sorry, but what the heck does sensor-based DR have to do with scoring a lens?!?

What the heck does DxO have to do with scoring DR or a lens?!? ;D

The hilarity that is DxO continues.

Give it up Neuro.... Give it up jrista....

You are just jealous that my 50 F1.8 that I paid $100 for outscores your $10,000 lenses and try to justify it by attacking DXO. Everyone knows how impartial and accurate DXO scoring is just like how all birders would rather use a 50F1.8 than a 500 or 600F4.
