Was it with the flash? K-x doesn't have focus beam.

heh, sounds like a attached flash's focus beam. The sigma DG500 super I borrowed has a very dim gridded red flash beam like that and it worked surprisingly well

Oh duh, I guess it was... went back and looked at the photo, it was with my 360 flash attached. Sorry.... I never noticed that before now. I haven't been taking many pictures in complete darkness!

I believe the small hole at 13 o'clock from mount is a microphone opening:

Yes, an external flash unit. Sorry for the confusion.

i was wondering the same thing.

is there a hidden latch somewhere on the k-x that opens up a secret AF assist ?

please elaborate.

oh, i see your clarification now. tnx

Thanks for the post. Did you do anything else besides noise ninja? I actually like the colors better in the before shots (note the pumpkin in the porch pic, for example). Exposure, too, on several of the after shots seems to have gone up. A few look overexposed.

12,800 looks useable for web viewing - looks uncomfortably noisy for print even with NR IMO.
But this is great - the K-x is a little workhorse.
Pentax's next flagship's gotta be a real winner when it comes out!

Ash, I thought print tolerates more noise than web viewing ?

If you are referring to the last two, I totally agree. I like the originals better.

The only change was "auto profiled" noise ninja....

Depends on the size of your print.

Can you tell me what settings you used in Noiseninja?, thank you.

you are talking about software power there.

I've yet to see a noise reduction program that actually improves the image.

The main problem of K-x is COLOUR. IMO.

I've played with RAW from K-x. It seems to me - K-x has strange yellow, red and green.
To correct the colour of each photo in convertor is rather lazy for me.

Yellow has green cast, red is with raspberry pink cast, green is a bit acid green.

The colour are not well-balanced and I can say it's rather pops colours.
With higher ISO - more acid. The jpeg from Raw and in-camera jpeg are rather similiar.

No way to set good colours with WB level in RAW-converter. Need to work under all colours separately.

As for JPEG - either pale, or too "acid".

Of course, there are a lof of pops colour-lovers...

Nothing at all is wrong with the K-x colours. Why do you even bother posting such foolishness. Get ahold of one and see for yourself.
