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"

Aye! Smells like a beached whale that just deathfarted.
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

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. :P

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. :D I think my favorite quote is 5:35: "It's the whale fart symphony!"

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

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.

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.
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.
The best camera is the one in your hands

Damn. If there was only a "for" after each of those "up"'s. ;P

The irony here is so thick you could swim in it, though! :D That a 50/1.8 outscores a Canon Great White is about the perfect testimony as to how overweighted and invalid transmission is on DXO's score, and how ludicrous the scores therefor are.

I always found there sensor scores pretty accurate. But this is??? These guys are smoking some pretty potent stuff. I shoot with a guy that has a Nikon 500 VR II and it is scary good, the VR is un real on that thing. But! He constantly comments on how sharp the pics from a 500 II are. Like every time we shoot together. I damn sure would not trade.
Another fellow I shoot with every once in a while has the Nikon 600. That thing is not even close to the new Canon 600 II IMO.

The Canon 500 mm lens mounted on a 22 MP FF sensor OUTRESOLVES the Nikon 500 mm lens mounted on a 36 MP FF sensor? And they are scored equally? Incredible

The Nikon 500mm rules @ f/32 in terms of actuance:
http://www.dxomark.com/index.php/Lenses/Compare-Camera-Lenses/Compare-lenses/%28lens1%29/1174/%28lens2%29/393/%28lens3%29/891/%28brand1%29/Nikkor/%28camera1%29/792/%28brand2%29/Canon/%28camera2%29/795/%28brand3%29/Sony/%28camera3%29/831

This might lead to a higher summed up score because DxO produces the score from data over the whole range. If this is NOT WEIGHTED with typical use scenarios ... this gives misleading scores while the measurements are correct AND helpful.

This might explain why Canons and Nikons 4/500 have the same scores - I would choose Canon's lens because it should deliver cleaner results @ f/4-f/8 - the typical f-stops I would use.
TOOLS: EF-S 10-22 | 60 || EF 2.8/24 | 2.8/40* | 2.8 100 Macro* |2.0/100 | 4.0/70-200* | 5.6/400* || 2 x 40D | 600D | EOS M  [* most used lenses]

I'd like to ask where DxOMark states the Score is summed over the whole range...because instead, I read: "DxOMark Score corresponds to an optimal focal length/aperture combination. The score corresponds to the quantity of information that can be captured by the camera. Each focal length/aperture combination provides a numerical value. The highest value is the DxOMark Score.". They're saying the score is based on the one best focal length/aperture combo. They indicate that right next to their Score, and for all three lenses that optimum is 500mm f/4.

Sorry, but I believe actuance at f/32 is irrelevant to the Scores, which are still BS...

That is interesting considering the Nikon has a minimum aperture of f/22  ;D

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".

DXO never said that they were "lens tests" only, so I do not see he problem.
