I'm having decent success with high ISO and Lightroom 3 with my K-7, this was taken as a JPEG with high noise reduction then noise reduction applied in Lightroom.

This was taken handheld at the very end of official twilight, it was almost to dark to use the viewfinder.

Camera PENTAX K-7
Exposure 0.077 sec (1/13)
Aperture f/2.8
Focal Length 16 mm
ISO Speed 3200
Exposure Bias 0 EV

Here's a shot from my K-7 taken with the FA 31mm Ltd. Taken at 3200 as a DNG file, and no NR used at all. The only noise that I would consider unattractive is in the darkest areas of the shot. Otherwise I think the noise is quite acceptable.

Coming from the K10D I was blown away by the high ISO capabilities of the K-7.

K-x high-ISO ladder

A few more K-x high ISO example JPG's, stepping through 6400 ISO to 12800 ISO. Very useful for night time parades and museums.

6400 ISO (DA40, 1/60sec f3.2)


9000 ISO (18-55 kit, 1/45 sec, f4.5)


12800 ISO (18-55 kit, 1/30 sec f4.5)

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

Very impressive bird shots with excellent detail retention for the ISO's in question. Please tell me you used a tripod, or a very fast shutter speed, otherwise you put my hand-holding abilities with the K-x/ DAL 55-300 to shame.

Thanks, they were hand held, 1/200-250. The K-x /55-300 combo is an unbelievable pair.

er1kksen: Just messing around after I saw the cool light coming through the trees above my head (it's actually from car headlights on the opposite side of a gorge, about a mile away). In the LR3 beta I tweaked the exposure and colors, NRed it to near-smoothness, and then added in a whole bunch of grain (because I like LR grain). Also added a slight purple tint to some of the foliage with the adjustment brush so there would be more interesting gradations. It certainly isn't anything you would call detailed, but I kinda like it.
Some extraordinary conditions, for sure, under which to obtain such nice results--good for you. Given that I practice meditation, some recognition, IMO, needs to go to the model who held that steadfast post for 30 seconds.

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.

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.
