The raw files are one their way to you as I type... now they will be in (much) more capable post-processing hands
After uploading these, dgaies suggested that we host the DNG's for the rest of the community. Which I agreed was a good idea. However, to help protect bandwidth, I decided to password the files to help curb abuse from external sources.

Hey, even the ISO 51,200 shot would be useful at the kind of sizes people post photos in Blogspot or Flickr.
We've got a Pentax Night Vision camera now...

51200 doesn't always turn out decent... If the exposure isn't right it can turn bad pretty quickly.

So does 6400 on K20D and K-7 (more so K-7)

Here is my take on 25600ISO, with some masking and NR in Photoshop. I left some grain in.

I thinkby looking at what I came up with its easy for me to say 2.5 stops over K20D and possibly 3 over K-7. I feel that 51200 is comparable to 6400 on them both. and 25600 is better than them both.

I like it!
Great job on that one!
I was quite happy to find that 51200 was not purely a novelty.
Also... I can't comment enough on the quality of the noise patterns with this Pentax system(very impressive).

PS. here's a link to an early first batch on my end: https://www.pentaxforums.com/forums/pentax-dslr-discussion/118728-k-5-dng-raw...0-51200-a.html

Not perfect by any means, but it does seem to hold promise as things mature.

Oh....THANK YOU...I've download files - open in UFRAW by default without NR.
Even without any sharp - good result.

BIG FILES!!!
http://fotkidepo.ru/photo/132601/31729lmlRCfE6im/iZiFHuHhYx/556032.jpg

It's from LR 3.2 without NR and with shapness 40@0.8

Cool IMO.


ISO1600
Lightroom 3.2 without NR - good IMO.

ISO400
http://fotkidepo.ru/?id=photo:556036

VERY_VERY GOOD from 80 till 800 without any NR in converter. 1600 is fine for me.
3200 and above are good with small NR in LR.

So what do you think of the ISO1600 output?
Have they made you a believer yet?

I think it would be usable in the studio.
I'd love to see some super resolution output from this system too!

PS. have you noticed that the ISO200 file retains more detail than the ISO100 and 80 variants? I think under the conditions, it might be better to aim for nominal if one is looking to squeeze every once of IQ out of this system. Which isn't at all bad when you think about it since the ISO200 file are so clean...


Also... there is good reason to beleive that ISO1600 is the maximum threshold prior to low level NR on the K-5.
Not really imperical, but definitely handy for the purists

I've put ALL Noise Reduction setting to ZERO in Light room 3.2.
just add COLOUR to 13.
Cool

ISO1600 and 3200 are working with very slight NR.

It's very good. I'm impressed that IQ has no any traces of softness and "soapy" like 7D.

It's plastic toy at the photo, but IQ is really good. Film like.

I can't say that K-5 is noiseless camera, but noise is well-controlled and easy to remove just only with COLOUR NR in LR.
I used 6 for ISO800, 10 for ISO1600 and 13 for ISO3200.

It's rather scanty settings

Very nice!

By taking note of the fibers throughout the scene, we get a great way to judge the overall IQ of the images. In this case, I would rate them both very every good.

And lets not forget... these are early samples too.
I expect a slight gain in IQ as we become better acquainted with the system.

My modest verdict - very good IQ for 16 MP APS-C camera.

"pretty good IQ for a 16mb APSc camera"

I know there is much more to learn about the new Pentax DSLRs BUT the early evidence is absolutely pointing to stellar image quality

I would ask - drop all qualifiers ("for an apsc", "for the money", etc) - and how closely to full frame IQ CAN this camera approach?

Frankly it is looking close - and I imagine that with good glass and a good photographer the gap will turn out to be very small

of course, the next generation of FF's are due out over the next 6 to 12 months

Good news - no any NR in RAW from ISO 80 till 1600 AT ALL.
