Originally posted by Jasvox I compared the the D3200 to the K-7, k-5 and NEX-5n and found the K-5 and NEX-5n to have much better quality at 1600 and 3200 when viewing raw files.

Originally posted by causey I had the same impression for ISO 3200, and I assumed the same conclusion applied to higher ISO, but now I think even at 3200 the D3200 is better. Much more detail...
Originally posted by JinDesu Are we looking at JPEG comparisons, or RAW? Because in RAW, the k-5 is trumping the D3200 once you reach 1600 ISO.
Even in RAW, the k-x is beating the D3200 at ISO 3200+. At 12,800, it's laughable - I can do noise reduction on the k-x file (some luminance, barely any color) and recover it nicely. The D3200 file looks like it needs a lot more color denoising.
I wanted to play with the RAW files for denoising, but my Photoshop and Lightroom doesn't recognize the D3200 files =\
Originally posted by Deimos I see a lot more noise (and chroma noise) in the d3200 files (RAW or jpeg). there seems to be a touch more detail in some areas, but most look noisier, less contrasty and with worse colour than the K-5.
I still prefer the K-5 output myself. But clearly a nice sensor for an entry level camera!
Originally posted by JinDesu Comparing the JPEG high ISO shots is straight from camera, and the k-5 version has NR turned on. My understanding is that the k-5's jpeg output at high ISO isn't so great - and a lot of review sites gave it flak because they never bothered to look at the RAW.
In fact, if you look at the RAW processed ISO 3200 shot of the k-x, it beats the out-of-body jpeg from the k-5. But once we talk about RAW files, the k-5 is king of this bunch (of course), and the k-x still beats the D3200. The D3200 just has a larger resolution - it has so much more noise than the k-x.
At ISO 100, the D3200 looks lovely. So yes - it's a great sensor. But even at ISO 800, you are getting quite a bit more chroma noise. And chroma always looks uglier than luminance noise.
Originally posted by ihasa Chroma noise is readily dealt with. The D3200 is resolving a LOT more detail - look at the hour makings on the clock! Downsample the images to K5 resolution, and I reckon they'll be decisively better. The question for me is, is such high image quality really necessary? Probably not, but it's still nice to have!
Originally posted by causey It surprising how good the K-x is compared to both K-5 and D3200 at ISO 800; but I still think the D3200 has enough detail to make up for the noise. Another thing: Canon T3i doesn't look bad at all. All these cameras are great. They aren't going to make a definitive photographic difference.
I took the liberty of processing RAW files from the D3200 and D3200 in LR4 RC2 then downsampled to match. And the obvious thing is where the added resolution from the D3200 easilly makes-up for the added chroma noise against the K-5, however... what I found particularly interesting is how much detail I was able to retain at ISO6400 using Topaz denoise with the D3200 at 1:1 - (very impressive imo).
Having said that, I think this model gives us a very good preview of what's to come. And though the D3200 doesn't exceed the NEX-7 at base ISO, it does however get the edge at higher ISO by suffering slightly less noise destruction. Though I wouldn't spend much time obsessing on anything passed ISO6400 myself.
Hope this helps.
