horrible comparison/review. absolutely incompetent, obviously not a photographer but a kid who read a little tech data on the internet, who apparently doesn't even understand what raw files are, plus without any original content. shameful

The real reason that the Pentax has better images (or potentially better) is because it has bigger pixels... First of all, 24 megapixels vs 16 megapixels, only dictates the print size... The pixel size of the Nikon 5200 is 15.3 um(squared), while the Pentax K-30 has a pixel size of 22.9 um(squared)... Which is actually close to the size of a full frame pixel. The Nikon D810 has a pixel size of around 23.7 um(squared)... This means that the Pentax pixel size is 1.5 times greater or 33% larger or the Nikon is only 66% the size of the Pentax. Point and shoot pixel size are around 1.5-2.5 um(squared)... The larger the pixel the more data it can acquire, store, process... in terms of detail, color depth, dynamic range etc., etc... Once the sensor has the data it is up to the software to process it, the better the software the better the final picture. Sometimes gains can be made by shooting RAW and having a full fledged computer with excellent software process the data instead of the camera's software... The largest pixel size is 53.5 um(squared)... so as you can see even a full framed sensor as with the Nikon D810 is about average size for a Full frame... This would indicate that the Pentax APS-C, being a smaller sensor would be above average size for this sensor and actually be in the same league as an average full frame sensor... The number of pixels only refers to the size of the picture and not the quality or detail while the size of the pixel determines the quality of the picture (subject to software processing)... Crop factor and quality of the lens also play into the final quality of the picture... The Pentax K-30 and K-50 are just about identical with the K-50 having a slight advantage of 51,600 iso vs K-30's 12,800 iso... Most everyone would probably opt to stop around 6400 iso and turn a flash on or increase the exposure time... That being said, the K-30, if being blown out the door at bargain prices is essentially the same as the K-50 (software mod - changed a number in the software from 12,800 to 51,600)... A hack could have done that... hahahaha...

240p for a image comparisson video. Great...

oooh 25000 iso is Disgusting

For a while now Pentax lenses have been kicking everyone's ass

Good intent, but too long!

Well, this reviewer loves to hear himself talk. The problem is that he says very little that is intelligible. The review could have been done in less than 10 mins. It's shocking how poor the images shot with the Nikon are. Plus, you can get the Pentax K-30 with the 18-55mm lens for $549 from Amazon. I can't see how anyone would choose the Nikon D5200. The Pentax K-30 body can be had for $499. Get a superior lens and you're in business. The K-30 seems to be the best entry-level DSLR around.

I have a Nikon D5100, and just ordered a Pentax K30. It seems to outclass the Nikon in many respects, but, there are 2 things that the Nikon might have over the Pentax: predictive autofocus and the D5100 14-bit RAW files vs. the K30's 12-bit. I doubt this translate to too much in all but the most demanding situations, I hear, however, the K30 gets astounding performance out of its sensor. I also think that the AA filter on the K30 might be thinner rendering the possibility of sharper images.

The Pentax K30 has less noise in the higher ISO range. This difference however is very small and i prefer the sensor of the D5200 becouse of the extra detail. However i do prefer K30/K50 body. 100% viewfinder more controls and weathersealing making it a more bang for buck camera.

Lol, how much do you want to bet this guy has a Nikon

Man, this video show only your lack of knowledge about Nikon cameras. Nikon has the worst (unusable for any serious work) JPEG compression amongst all of the DSLR makers, you should test only RAW vs RAW...then you'll see how exactly is the Nikon far far ahead of Pentax and Canon.

K30 should be compared to 7000d, it's so much better than d5200 or the over hype 650d or 700d in term of image quality
Написал: geofftuba, 07.10.2013, 18:14

I question the author's objectivity. Based on the images he displays, I cannot find an example where the Nikon approaches the Pentax in dynamic range, clarity, or detail. The "noise suppression" of the Nikon is simply lost detail in the digital negative.
Написал: Ivan Powers, 26.06.2013, 04:42

What if I engineer some tests and make the pentax look exactly like you're making the nikon look?
Написал: will db, 13.07.2013, 00:11

Bla bla bla... the Pentax is so obviously better, it's staring us in the face from the images! Sharper, cleaner, less luminance noise - there's more colour speckling at ISO3200 but that's easy to get rid of in a nondestructive way.
Написал: terosyva, 23.06.2013, 18:22

Ok.. Xplain it to me.. How the hell 16mpx camera is sharper than 24 mpx ?? "With an overall sensor score of 84, the new Toshiba sourced CMOS imaging chip in the Nikon D5200 achieves the no.1 spot for APS-C sized sensors" DxOMark...
Написал: BernhardRottweiler, 23.09.2013, 19:21

Cit: "...there's more colour speckling at ISO3200..." - it could be related to the K-30 image being interpolated to 24MP.

Oh my god, how dull of a review.
Написал: Shane Urbanavicius, 30.04.2013, 13:08

I'm in the market for buying my first DSLR camera, I'm 17 and in highschool, and I want a camera that will allow me to take the best depth of feild photos possible, superior video would be a secondary benefit for me; not as desired. I've narrowed my choices down to either the Pentax K-30 or the Nikon D5100 (and now the more expensive D5200), I want to believe what you guys are saying about Pentax, but the image/video quality of the Nikon's I'm seeing on youtube visibly seems much more superior.

how do you increase the MP in the pentax k-30 files?

the k30 kills the nikon bllodyhell its obvious
