Web Analytics RiceHigh's Pentax Blog: K-5 Scores the Same DxOMark as the 645D!

K-5 Scores the Same DxOMark as the 645D!

See:-

645D Vs K-5 Vs K-7

So, now I know that why "the K-5 is what everyone needs" and that hence there is simply no meaning of the 645D at all, as the RAW IQ is just the "same"! ;-D

And, just not to waste the remaining choice for the comparison, I selected also the K-7, which is the Pentax DSLR that scored the lowest mark as tested by the DxOLabs. The poor little K-7 really looks rather bad for this head-to-head direct comparison! :-(

Still waiting for the D7000 result, though. It would be interesting to see if the results would be more or less the same when the same sensor is used but without something in front of it that causes light loss. In the meantime, we can compare this:-

NEX-5 Vs K-5 Vs A55

Btw, just Welcome to the New King of APS-C DSLRs of the DxO BenchMark! :->

Still, for critical thinking for both sides of anything, do read this:-

Ten Reasons for Thinking Twice before Decided on a K-5..

Update (11-8): D7000's DxOMark is Out! I think the following would be the hottest comparison!

D7000 Vs K-5 Vs 60D

Well, as we can see, the results of the D7000 and K-5 are indeed very close. So, in fact, the "super IQ performance" of the K-5 is indeed a Sony achievement, but not particularly a Pentax one!

Monk, what exactly must happen before you get enthusiastic about something? Enjoy the news and party with good friends :)

645D = medium format = completely different application. If you buy medium format for the dynamic range of the sensor, you are a fool. Rice, you have made a foolish comparison.

WOW.
RH, you have managed to transform an extremely positive achievement of a Pentax camera in a rather negative entry in your blog...congratulations to you too !!!
You may not be aware but 39mp is more than 16mp.
Looking further on the DxO site, the K5 has the same dynamic range as the Nikon D700 and the canon 5D Mk 2.
Pretty awesome achievement for Pentax. Well done.

The K5 only scores this high thanks to the 14bit dynamic range. But still this is the best sensor in it's class. It's almost as good as the Canon 1D4 sensor which is a lot bigger en comes close to FF quality, but saying it's better the a 645D is cutting the corner. It is for a A4 (10") print but not on A2 (20") and above.
But still, this is the camera that will replace my Ist*D and makes me thinking about selling my Canon 1D3.
I think Pentax made the right decision dropping the Samsung sensor. I think this camera can be a winner if the can solve the some minor inconveniences through firmware. And they already fixed the RAW-buffer....hmmm.

what will also be interesting is if they continue to mirror the sensor choice by nikon semi pro camera. Wasnt a lot of the angst due to be able to diretly compare features/price with nikon this round? I thought that was one of the reasons for choosing the samsung sensor, individuality against the canikon crowd.
J J Abrams, Individuality in pentax comes from the fact thet the philosophy of the photo machine itself is different, I see it this way: canikon have very good but chuncky cameras, very good but chunky lenses and are offered at a wide range of variety and prices.
Pentax offers few choices, of an unimpresive size but (at least to my taste) of great quality and ergonomics. It seems to me as if canikon where the equivalent to american cars, and pentax would be a citröen, odd, unasuming but surprisingly well thought.
I love my K10, Love my k7 (with it's no so good sensor and everything, anyway that's why my slowest lens is 2.8 and shoot in mostly good light), of course, I will get a K5 as soon as I can, hopefuly before the end of year, and it will bring me a new world of night photography with my beloved, fast and compact lenses...
That's what I call individuality...
Rice, by the way, I know you are secretly exited and saving for your own K5 and will ditch that 5D you used to love...
Awesome, especially in dynamic range part!
D7000, what D7000? there are a damn bug found in it, Nikon needs to fix that sh$t, the damn AF is crap and none existence for a lot of users...

By the way, did you see the K-5 up against 7D and D300s comparison?
Ok there is good news to pixel measurbaters, but still sir RiceHigh manges to slash of the 645 and is waiting for the nikon 7000 results?

When the K7 had bad dxomarks he was fond of it: http://ricehigh.blogspot.com/2009/12/dxo-scores-c...

Please ricehigh post a new comparison if you dare :)

Got one, 14 stops is there. Shooted couple of images at iso 2500 against light, excellent nothing burned in like normally. Handheld HDR is good also but IQ is not the best, I like PP version of HDR more. HDR is finally handheld and with SR. AF was very sensitive also. ISO 6400 is remarkable also. Tested also iso 20000 hadnheld HDR, remarkable also in total.
Guys,

Do not forget that dynamic range published on DxO vebsite is normalized for 8mp. Therefore any camera having less that 8mp will show less dynamic range than similar same camera with the same DR per megapixel, but having 8 or more megapixels.

K5 has bigger DR than K-x based on these tests, but lets not forget that K5 has 16.3 effective MP while k-x has only 12.4mp.
It would be interesting to know how they compare in DR per megapixel!

On other side this shows that consumer level Canon DSLR's DR is not very high, as for example 550D has 18.7 mp resolution, but in DR is behind some lower resolution cameras (like Nikon D90, D5000, Pentax k-r, k-x).

The Pentax K-5 had a stellar DXOmaRk performance, based on its overall score it is currently ranked as #5 among ALL Camera sensors tested at DxoMark. That's right, it beats ALL Canon DSLRs, and it is only surpassed by the Nikon D3X/D3S (FF cameras)
I never knew this outcome why i bought my Pentax K-5 last month , but all i remember was couple of years ago about the exmor being in a pocket camera. Just a thought in my mind that already happens today (how about this exmor in an aps-c format). Gotta be real awesome since the picture sample from pocket camera being that small produce a well defined subjects, so i did not hesitate when it shows up on the shelf.
Check it out , i did a little test using ISO-25,600 in dim ligthing of star ferry (TST). Am really excited to got out more, but am still busy that's why my photos are quite that few.

...buaobao
most stupid blog entry ever

"K5 has a stellar DXOmaRk performance" !!! Much better then 7D actually, higher scores for "Landscape (Dynamic range)" and Sports
(Low-Light ISO), whatever that means. So what? Does it translates into better IQ? Or handling? Or performance? Do you really believe you can get better technical IQ or more usable images shooting sports with K5 as with 7D? Or that K5 that better then 7D shooting landscapes?
The high ISO performance of K5 remains to be seen in systematic reviews. I have played a couple of days with Alpha 55V (same sensor as K5) and in real life in low light scenes i saw a lot of noise in shadows/blacks up 400 ISO. The keeper rate after shooting my 1 y.o. daughter in low light was considerably higher with my old 40D then with A55, so A55 goes back to the store...

And IQ for a nikon dslr this is also solely due to the used sony sensor? c'mon ..
