Iso25600

You bet it is grainy, but otherwise this is a useful image. Song Sparrow buried in the shadows, DA*300, TAv mode, 1/500s, f8.0, +2EV then pulled down -1.0EV in post, ISO25600, maximum luma NR with lightness blending in post and some chroma NR. - Jack

From a few shots between my K5 and K3, the K3 shots were as good if not better.

Regarding the K3 against other cameras, I'll create a more detailed thread on the two cameras later, but here is a shot at ISO 12,800 from the K3 and the Nikon Df which currently has the cleanest high ISO available on the market at more than twice the cost of the K3.

Shots saved from RAW to JPG with no other PP........

The K3....ISO 12,800



The Nikon Df.....ISO 12,800



The K3 is no slouch....

The Nikon colours are more pleasing in this shot.

I've found some 'noise control' setting suggestions offered by another K-3 user to be very useful.

If your scene and subject are settled in place, simply use "Sv" mode. Let the camera apply the rest of your settings. For me, the image starts to become difficult to pp with NIK Define at about iso 12,800 (you might be able to push it higher). Other suggestions for reasonable OOC jpg results include: Custom iso NR set 100-800 (off), 800-1600 (low), 3200+ (medium). And Vibrant color profile with sharpness set to Fine +1.

Cheers... M

Just going by the wonderful sample pics from you all that are now plentiful with the K3, I really like its noise levels and how it renders it. I think it seems to be what I will call a "mood" camera. Much like I feel about the K10. I don't think I want super-clean images at high ISO, in many scenes I think a bit of grain often conveys the feel and vibe of the location at time of shot. I've been leaning towards a k5iis for several reasons, but the style of the K3 images is appealing to me increasingly. To the point that I'm not sure what my upgrade path should be. Of course these are entirely subjective opinions on my part. All that is clear to me atm is that Pentax continues to build great cameras for its users.

Based on what I've seen here on the forum and on some early, low-light "test" shots (i.e., taken on the night my K-3 arrived), my sense is that my K-3's output is noisier than that of my K-5. However, as I continue to play with my K-3 and evolve from "testing" to "using", I'm finding that - for the kind of photos I shoot - the practical difference between the performance of the two cameras at ISO 3200 is pretty small. Here is an on-the-fly pic taken during the bedlam of Christmas morning with my K-3 attached to my just-unwrapped FA 31 () at ISO 3200, 1/80s @ f/2.8. I processed the shot more-or-less as I would do with K-5 files, although - since Apple has yet to update Aperture with the K-3 PEF profile - I've necessarily added the step of converting PEF files to Aperture-digestable DNGs with Adobe's DNG converter prior to importing into Aperture. In this instance, I cropped the pic to about 60% of its original area, applied a bit of NR (but not much to preserve detail), adjusted white balance, bumped exposure around +0.5EV, tweaked contrast, sharpened and converted to a JPEG, which was further sharpened very slightly prior to uploading to Photobucket and copying to the Forum. Throughout the processing, I didn't see anything remarkably different than I would have were this pic shot with a K-5 (except perhaps a bit more detail was retained after cropping).

This pic was posted a few days ago in the Post Your Photos section.

This shot is at ISO 3200. It needed a bit of NR in LR4.

So many schools have been closed due to declining enrolment, many turned into community centres…

K-3 at 3200 ISO…, noisey, but better than not having the image.
I shot my rental K-3 at ISO 3200 (raw) then processed those images in DxO Optics Pro using their PRIME demosaicing algorithm (warning: takes twice as long as their "normal" algorithm). The result was essentially nearly noise-free images without any blurry effect that you get using post-conversion de-noise tools like Topaz DeNoise or NoiseNinja. In short, the combination of DxO and high ISO is unsurpassed IMHO. (I regularly shoot ISO 6400 on my D800 and DxO has made all the difference). If I end up purchasing a K-3 rest assured I will be using DxO on its raw files.

Thank you for your notes and comparisons. I currently use LR3 which I find fairly straight forward. I am an amateur photog who does a fair amount of low light pics. Is DxO Optics Pro fairly straight forward compared to LR3?
