First let me say there are some really good photos here. I looked thorugh quite a few pages and the K7 pictures seem to have a little less "grain" (is that what is now called noise?) than the KX offerings.
Is this just because the K7 is the bigger and better, or am I seeing things that may not even be there? I will probably start with a KX mostly for budget reasons at this point.
I do like to shoot available light as much as possible.
It probably has more to do with web compression and different levels of NR used in post (or set in the camera, for that matter). It's pretty well established that the K-7 is a bit noisier in RAW (and equivalent jpeg settings). Shooting situations matter too; shoot at high ISO in good light and it won't look that bad at all, whereas shooting at high ISO in poor light is going to produce a lot of noise.

While some may be posting images with no NR, I would assume that the majority have at least the default in camera NR, and quite a few - especially those shot RAW - definitely have NR done in PP.

I also am confused as to which pictures someone could be looking at to get the impression the K-7 has *less* "grain" (noise is the correct term) than the K-x. It's important to comapre apples to apples, though - an ISO 800 K-7 picture will have less noise than an ISO 6400 K-x picture, and different amounts and types of NR will affect the results, as will the nature of the scene itself. But the evidence should be pretty overwhelming at this point that the K7 is not better than K-x in this respect, but that rather, it's the other way around. The only open question in anyone's mind should be how *big* the K-x advantage is. My impression is that it looks pretty big if you shoot JPEG using default settings; less so if you shoot RAW and try to optimzie your NR in PP for each camera accordingly.

A couple of shots of a pair of beautiful juvenile mourning doves that were in our garden this evening. It was dusk so I had to shoot with high ISO to be able to use an aperture to get decent DOF. I can't believe what the budget combination of the K-x and 55-300 can do. PP with aperture and Nik DFine.
ISO 6400
ISO 5000
I know I'm a bit late -
but those are amazing shots on the K-x VaughnA -
really, really good.
The results look as good as most other cameras' ISO1600.

er1kksen: The mosquitoes were the worst part about holding still. Much more difficult was hitting the shutter and then finding my way over to the tree and getting in position on it (it's hanging over a nice deep gorge in near-complete darkness before the exposure started 12 seconds later, and then getting back up off the tree and back to the camera in the dark once again. Without falling into the gorge.

I really need a remote. Really really.
LOL I am with you: mosquitoes accompany me on my hiking adventures too. BTW, I bought a remote, though I do not remember the sellers' name for less than $4 on Ebay--shipped. Here is a for example--you may want to search out Ebay more:

Thanks, I've been looking at those recently. Just haven't got around to a purchase yet. No money in the bank but I'm getting paid for a print order soon, which should cover a $4 remote with no trouble if I want it to.

Well, see now this is why I am asking these questions. I am new to the DSLR. Certainly puts my mind at ease about the KX.
Marc, I figured noise was the correct term, but it still looks like grain....

Wow, after looking at the latest pages in this thread I really want the K-x! But I guess I'll just wait till Photokina and see if they release a K-7 super or an entirely new model at the same price range as K-7 was.

Remnance of a lens modification...

Another just for fun ISO6400 snap.

I was bored after I found out I couldn't remove the actuation lever on my K 35mm 3.5, so I decided to take a low light picture and see how it would come out in ACR6. The short story is: the image has very little PP done to it(quick pass of NR is about it), it needed a slight push(.5 eV) in order to balance out the shadow detail on the lens mount. However ACR and Denoise made it possible to keep things under control.

K20D, ISO6400, 1/80 with HELIOS-44M-7 f/3.2


As always, can be viewed original size here(highly compressed). What's the point of shooting if you can't use the full size images?

Okay one more boring desk shot. Except this one didn't make it into Photoshop(ACR6 only).

K20D, ISO6400, 1/80, w/HELIOS-44M-7 f/3.2

click image for actual size

No debanding, masking or Topaz Denoise applied... Not to shabby
PS. I think I really like the HELIOS-44M-7, seems like one helofa' sharp lens!

Helios lenses have reached cult status---so sharp in the center with some special bokeh too.

John, please keep those awesome high ISO shots coming--nothing boring about them.

I agree and that K20D continues to amaze me. Here is a K20D image at ISO 4000 with O, NOTHING, NADA, PP done except for cropping and resizing. Turned Out I liked it as is. I know this one would clean up nice with some pp, but I liked it.
