It is true that shots taken with my K5 seldom need any sort of "denoising" at up to ISO 1600 and at times even at ISO 3200 (given that there was no exposure problems during the shot). I'm sure the noise is related to the number of pixels on the APS-C sensor, as well as the newness of the camera (no raw profiles), and also to what Pentax engineers wanted to achieve (they tend to allow noise to preserve detail).
So here is another post about the K-3 noise (at least as of Nov. 1, 2013 - with no mass-market processing software recognizing or profiling the PEFs).
And since this is a "post your K-3 images" thread, here is the full image I talk about in that NR post (note that the splotchy neutrals are due to jpeg compression and sRGB colorspace - I shoot in AdobeRGB and process in 16-bit):
Thanks for the info !
I wonder what that will involve when people start going out (with the K3) for some wildlife shots (with 300mm + lenses) and have to shoot in less-than-ideal lighting conditions, and having to still use a high shutter speed ?
My sole trick with the K5 at the moment is to use TAv and let the ISO floats ... sometimes it gets me right up there in ISO, although not too bad as long as the eposure is right.
I suppose it will be a bit tricky to manage the K3 RAW files (I use DNG with the K5) with CS5 and/or with the supplied Pentax utilities coming with the K3.
I am just about ready to place the order for the K3 but .... I am still unsure.
Thanks again for the feedback.
