well well well, where is ET2? i think his world is going to come crashing down when he hears this.

"Fortunately, the K-5 gives you the ability to turn off noise reduction entirely, ridding your images of any sort of detail smearing. The result is immediately noticeable, as you retain sharp details all the way up to the native ISO cap of 12,800".

oh but thats not all.

"While the Sony A77 pulled off fairly respectable results up to ISO 1600, it really starts to fall apart quickly at ISO 3200. It has two things working against it in these tests, I believe. First is the fact that the sensor has a significantly higher megapixel count than the Pentax K-5, and cramming more pixels onto an APS-C sensor will generally add to the noise. The other issue I noticed though, is the inability to be able to turn off noise reduction. Sony’s noise reduction smears the details quite severely, even at the “low” setting, and renders the image pretty much unusable".

hmm, so it seems sony have been the poor joke of a pro dslr, not even able to turn off NR. what a shame, ET2 your flagship camera has cooked raws and it sucks. haha. omg this is so funny.

rofl, so i guess the k5 doesnt have to have "cooked" raws, and we just saw what NR turned off looks like compared to the a77, an obvious win. let me repeat that, the k5 with no NR wins against the a77 WITH NR and it also wins with no NR against the D7k as this review also states. so i guess theres no arguing now, pentax are the kings

of apsc iso performance. sorry sony guys, just keep shooting at 100 and u will b fine

Thanks - I wonder if the new K3? will have this 24 mp sensor - I hope not.

dont worry if they do, think about how much better the k5 and k-01 are than the a55, a57, a37 ect and its the same sensor. pentax will take that 24mp cmos and make it work some magic. i actually hope they do use it, bc it will show how much better the a77 really could b.

i actually like sony as a company, but making subpar cameras is something i cant support. sometimes u need to prod the cow to get the milk.

I sure hope Sony stays in the sensor design/building business and continues to make sensors available to other manufacturers. The sensor is foundational to the IQ success of the K-5 and K-01.

i agree, i think everybody but canon would b much worse off without sony's sensors. and just so no fanboys try to talk trash, my first post said "raw" and was supposed to b "jpeg" as the review says, sorry for the typo

Why rub it in? it's a jpeg test and the K-5 did well. Ok.

But calling et2 up for more, is like walking about in a lightning storm wearing gold plated-aluminum jocky shorts.

At any given moment, there is a sort of all pervading orthodoxy, a general tacit
agreement not to discuss large and uncomfortable facts… Anyone who
challenges the prevailing orthodoxy finds himself silenced with surprising
effectiveness. - George Orwell

“It's not a matter of whether the war is not real, or if it is, Victory is not possible. The war is not meant to be won, it is meant to be continuous. … The war is waged by the ruling group against its own subjects and its object is not the victory over [the purported enemy], but to keep the very structure of society intact.” George Orwell, 1984

I think this is JPEG only. What he keeps banging on about is the high ISO NR which is applied to raw data.

Take a look at dxomark.com and see how much they like canon sensors - not so much.

Dean, I'm thinking the iteration of the 24MP sensor that Pentax gets is probably going to be more than fine - that A77 is an SLT design, which robs light, requiring more gain to make up for it which increases noise. Sony's method of dealing with that noise is apparently mandatory, crudely-implemented NR.

Anyway, Pentax will probably do with that sensor that they did with the 16MP Exmor in the K-5 - take it right to the top of the class.

I'm excited to see the next Pentax flagship. (I'm just hoping it's a DSLR. )

Funny now you like jpeg comparisons?

So now we have it settled. 5N has superior IQ than both K-5 and K01, according to DPR and IR studio tests. End of of this discussion.

Thanks for confirmation.

By the way, K-5 is supposed to be better at high ISO than A77, even when A77 is down-sampled to 16 MP. That's due to "translucent" mirror in all SLT cameras. It's a design compromise that has some advantages too (1) 12 fps with AF, (2) PDAF AF in video (3) no mirror related blur, (4) no shutter related blur, as all images can be taken with electronic first shutter curtain .. but on the negative side, the camera will be 1/2 noisier at eqv ISO.

By the way, I don't have A77, nor do want one, because I just don't like big black cameras ... give me a small camera with all A77 features, and I might consider it

as u can see in the review, the a77 (along with other sony sensors) cooks their jpegs to death with NR and it cant b turned off. this creates as unfair comparison as u claim with the 200+k5 raws. any comparison, including the 5n, is void as it is an unfair comparison. as u read, the k5 can turn off jpeg NR and was tested as such. u cannot call jpegs customizable in camera when u cant even turn off NR. looks like all those sony jpeg comparisons are worthless.

LOL good for Sony, finally they've managed to make good use of their own sensors, instead of letting others make better use of their sensors than themselves.

Good job Sony. Haha.

Except for D3x vs A900, which was $5000 extra, I believe that claim is a myth..

except its not, all u have to do is look at all the 16mp cameras out there. k-01, k5, D7k, all fair much better in comparisons than sony models like the a37, a55, a57, 5n. even dxomark scores them higher than the sony models. sony's best 16mp camera was the a580 and they scrapped it for these slt junkers. a shame.

The first three cameras that you listed should score 1/2 stop lower on Dxomark due to translucent mirror (remeber 5 pints on dxomark equal 1/3 stops).

The difference between 5N and K01 is like 2 points? That's not even 1/3 stops .. that's like 1/6 stop or something so within margin of errror. And the difference between A580 and K-5 was 2 points too.

So I was correct and you were wrong.

Try again

You can repeat that all day if you want till you turn blue, but K01 isn't better ISO 6400. It's just applying more RAW NR.
