Awww nuts.

From one of the other threads, it looks like the sensor in the K10D is the sony 10meg sensor. The same one as in the Alpha.

Does that mean we are going to be getting the same crappy high ISO images that the Alpha is seeing? Or can Pentax fix that in it's PRIME engine?

I didn't buy the Alpha because of this issue. I've already ordered the K10D, but now, hell, I don't know what I'm going to do.

Ouch out

almost as good as the xti. Same thing. Not everything is based on
the sensor.

Yup, been looking at the posts in the D80 forum and people seem to like the camera. Also the pictures so far look like they have a handle on colour/noise. I think N*kon just made themselves a nice upgrade for the D50.
 
It's a Sony sensor, similar to Nikon D80.
But internal image processing is different with 22 Bit A/D converter.

So K10D is not going to be a "noise wonder" (otherwise ISO 3200 would be possible) but I'm sure it won't be that bad.

best,
Christian

Except that those noise-controlled images are pretty soft.

And out-of-camera JPEGs to boot.

I wonder if we'll see a real noise comparison based on an ACR RAW conversion with all the same settings, similar lenses and identical subjects. Probably not.

Disappointing really, as JPEG performance doesn't concern me all that much and RAW comparisons seem rare.

Pentax are well aware of the noise issue. Low noise at high ISO was one of the key selling points for previous Pentax DSLR's when compared to other brands. Pentax do understands the importance of this issue for it's customers. That's why Pentax with the K10D introduce new technology, choosen to give as low noise as possible. Pentax goal and expectation is to deliver the lowest noise among the 10Mp competition.

Take care

10MP sensors are a step back in regards to sensitivity, D80 and 400D look more pleasing then A100, but toss away more detail, but people prefer this. Also the sony is very sensitive in regards to underexposing, and hence the noise is more visible.

The Sony sensor is very capable even in the A100, look at some of the entry's in the sony forum;
Nice comparison of different iso's and exposures

So the sensor and the A100 are as good as D80 or 400D, but that is just my opinion.
 
Don't you remember when shooting ISO 64 or 100, or maybe 400 on print film if you was brave enough. I remember shooting Kodachrome 25 for several years of my photography life. And you are scared because your pictures might be a bit noisy at ISO 800? Come on.

Remember with the K10D you'll have 3 or maybe 4 stops of room to play, so even if is the worse noise of the 10MP cameras (something that I doubt) you still can shoot in low light with please.

Really I don't think Pentax will come out with a sensor with noise pattern worse than all the current 10MP cameras around. They have learned from everyone else's mistakes.

I hope the K10D will give good image quality at high ISO. I use high ISO a lot.

But looking at unsharpened images is not meaningful. I usually find some degree of sharpening necessary, and sharpening will make the noise more noticeable.

My introduction to 35mm photography was with a Konica-made rangefinder. Most of my color photographs using the camera was with Kodachrome II and X (iso 25 and 64 respectively). Looking back I sometime wonder how I took so many decent slides. I was more careful about how I took photos in those days. One thing was learning how to hand hold the camera in order to use shutter speeds of 1/30 second and longer. Image stablization was something of science fiction.

Current Pentax cameras also tend to underexpose at the slightest hint of a burned-out highlight. I love this when using a low ISO setting, but really hate it when I need high ISO. I've often wished my camera could be more intelligent in this area.

Roland,

In my readings here I have come to trust your instincts and information.

I confess I am worried for the image quality at high ISO myself... and morso when I found out it was indeed the sony sensor.
However, with you leading the chorus of hope, I feel somewhat better about it.
I am keeping the faith, the best I can.

Though the lack of samples makes me more and more worried about it every day. :-)
I hope your right about it all....
I really do.

It's what the RAW button is for - try your best at the exposure, and if you believe there might be a highlight that affects the exposure, hold RAW and develop in-camera :-)

Reality is that 10MP sensors are more noisy then 6MP, Nikon and Canon have more "pleasing" NR then Sony, but if you take the raw image, the quality of all those 10MP's are very close. People debate about better wiring and better filters in the Pentax, Nikon or Canon, but I believe they are all on par, the difference is the NR algorithm's ...
