It would be very interesting to review the Nokia Lumia 930
At first place? second? ...fifth?
Many thanks in advance.
Comments on cameras / Re: are the dxo lens score sensor size specific?
« Last post by nhojuhc on Yesterday at 08:40:41 pm »
I compared the panasonic leica 25mm f/1.4 on the olympus omd em1 mII vs the sigma 35mm f/1.4 art on the pentax k-3. The sigma was sharper, had lower chromatic aberration, vignetting and distortion, both had transmission of 1.8, and yet both had a dxo lens score of 27. Please enlighten us. thanks.

I don't think DXO needs to enlighten you for this. Consider this:  Lenses are some of the demanding precision manufactured products out there.  No two lenses are exactly alike, not even the ones that come off the same conveyer belt.  There is always going to be some sort of statistical deviation from the norm. Just like in computer microprocessors ,there is a tolerance allowed.  So what does that mean?  Give me a Sigma 35mm f1/.4 and I will find you a Panasonic Leica 25 f/1.4 that 's sharper and Vice versa.  Don't believe me?  Go look at the blogs where they test 5 of the exact same lenses for sharpness.

I really don't get it. As an end user i pay for the best possible picture. So if i get 40 MP resolution with the Canon-Sigma combination and 37 with a Nikon-Sigma combination (assuming Vignetting etc. is comparable) i would expect a higher rating for the Canon-Sigma combination.

How the reolution is achieved is secondary. If Canon uses a radically "overpixeled" Sensor or Nikon uses a better geometry (or whatever) is part of their strategy. In my personal opinion the Dxomark rating is misleading in this way. If i search for the best possible combination i have to go down to place 9?! If i compare it with CPU benchmarks i'am also not interested, how a good performance is achieved (MHz or architecture), in a Single or Multi-core benchmark i'am interested in the absolute performance.

I know this subject is a matter of opinion but i understand when people are confused about it.

Hi guys at DxOMark, you do a wonderful job, Thank you to all.

Is this lens in for testing ?, if not, when could we expect test results.

Like seemingly everyone else on dxomark, you don't get it.

The overall score isn't a "lens score", it's a "lens+sensor combination" score.
That's why the score changes every time you choose a different camera from the "mounted on" dropdown.

So why is the Canon 5DSR version rated lower? Because you're paying for 50 megapixels, but despite excellent glass you're only getting 40 megapixels worth of sharpness / detail. And that loss happens with every Canon sensor - Attach it to a 24 megapixel 760D, and you only get 18 megapixels of detail. Put it on a 7DmkII, and you only see 14 megapixels of detail on a 20 megapixel sensor.

But if you get this lens for virtually any nikon camera, you get the absolute maximum level of detail that the camera is capable of. Use a d800 and you get 36 megapixels. Use a d500 and you get 19 out of 20. Use a D4 and you get the full 20 megapixels from its sensor.

Basically, the lens is being held back by Canon's sensors, which lag behind Sony and Nikon. That's not Sigma's fault, but the point is to pass info to the consumer so they can make an educated decision. If I have an older D800E and a brand new 5DmkIV with virtually identical megapixel count, I need to know that I'm losing about 7 megapixels of detail if I choose the canon mount of this lens.

Nubia Z11 = Nokia 808 Pureview or Nubia Z11 > Nokia Lumia 1020

Very strange indeed.
Perhaps someone can donate a proper calculator to the poor fellas at DxOmark?
Or maybe they're still using a an old Adobe Photoshop Express (or DXO Product) with that arithmetic bug. Oh dear! :-)

It would be nice to see some tests of Pentax lenses on FF (K1) too. Especially the current FF lenses like DFA*70-200, DFA 100 macro, ...

DXO optics says it's supported but are not the tests done for DxO optics providing the data for DxO mark ?

it's becoming quite septical if a test would come through, they might just wait for the iPhone 8 / X
