D7000 can't catch K-5 at DXO mark

ogl · 11-08-2010, 06:24 AM

DxOMark - Compare sensors

The results are very-very close...but

real - measured ISO of Nikon D7000 is lower than K-5 has

D7000 has overrated ISO

for example,
ISO100 = measured 83 vs 91 (K-5)
ISO200 = 167 vs 183
ISO400 = 328 vs 363
ISO800 = 658 vs 717
ISO1600 = 1269 vs 1417
ISO3200 = 2627 vs 2864
ISO6400 = 5197 vs 5873

DR (measured ISO)
K-5 has 14.12 Ev at ISO80 (70)
K-5 has 13.7 Ev at ISO100 (91)
D7000 has 13.87 at ISO100 (83)

K-5 has 12.82 Ev at ISO200 (183)
D7000 has 12.91 Ev at ISO200 (167)

K-5 has 12.05 Ev at ISO400 (363)
D7000 has 11.97 Ev at ISO400 (328)

K-5 has 11.14 Ev at ISO800 (717)
D7000 has 10.96 Ev at ISO800 (658)

K-5 has 10.36 Ev at ISO1600 (1417)
D7000 has 10.1 Ev at ISO1600 (1269)

e.t.c.

what I find most interesting is the linearity of the DR um.. curve. Curious....

Very close indeed. But all the numbers aside, for all practical applications K-5 and D7000 would perform equally well. Both cameras are very fine pieces of equipment capable of producing exceptional results in the hands of skilled photographers. So I would call this a tie.

Big G · 11-08-2010, 06:48 AM

Interesting; you would never notice the difference in image samples.

Top work by both cameras.

That would be a fair assessment. Congratulations to Nikon! It's not looking good at all for Canon at this moment.

I don't want to risk repeating myself on every thread regarding this remark, but there is much more to a camera system than what it scores in DxO. Given that the these are brand new sensors in brand new cameras, then it would worry me greatly if they weren't at least as good as technology that's in DSLRs that are over 1 year old.

Nikon and Pentax would have had their names dragged through mud if they released brand new cameras that offered absolutely no step up in technology.

yeah, NOW you wont, took them awhile.

Hell the new high-iso king.

It isn't, and the dumbed-down 60D doesn't help (yes, I know it's good for video, but it's no longer of the same class as the 50D, so if I were to buy a Canon and wanted something less expensive than the 7D, I think I'd look to the 550D instead).

But that 18mp sensor is already more than a year old, I would be surprised if they're not already testing something better in their labs. I wonder when a replacement for the 7D is due?

K-5? D7000 has overrated ISO. 1162 vs 1167 = it's inside the limit of measuring accuracy

End of next year most likely. Or it may be on a three year cycle like the 5D mark 2 but who knows.

Here is a question. What does the smoothed part of the curve mean? I noticed this on a few of the other Pentax cameras too, but on none of the other ones.

too bad the A55 didn't do as good. wonder if they have a regular mirror SLR on the way to get things right

Smoothed part of the curve is to show the range where NR is applied to the sensor raw images - and that is after 1600 ISO...
