K20D VS Canon 40D High ISO (Not 56K Friendly)

[Rickster]

In the images I posted above the orientation is ...

K20D - D40
K20D - D40
D40 - K20D

In each case the K20D out performs the D40 IMHO.

I am very impressed with the K20D's noise performance and will be adding this tool to my kit as funds allow.

I processed the 3200 ISO image ... it looks like the light source was flourescent as I had to tweak the red channel a bit for hue and saturation. Maybe that is why the 40D images have the red shift.

Here is the K20D 3200 ISO -> Noiseware Pro - Resize 50% - Resize 50% - Hue and Saturation - Smart Sharpening .5 50%



This should give a good idea of what a print should look like. I like it!

Thank you Chris for the images! By the way, was the lighting fluorescent?

Which images above have the least noise and highest detail?

They are focused differently - you can't compare them.

Excuse me? Just what does focus have to do with noise?

As far the detail goes, in all 6 images the mirror box appears to be well within the DOF.

I was takling about details - focus point was different, so even if the mirror box was *within* DOF, Canon would have less detail.
The problem with K20D image is different WB - the blue channel is working much harder, so I don't think you can compare noise either...
Overally, I think those samples are very poor if we are talking about fair comparison.

I find the Pentax looks like the nicer High ISO picture, but I'm not surprised.

I also feel that the real test is the actual print quality, on poster sized paper of course. But I would think that the Pentax would win here as well

I think prints from both cameras will be excellent with an edge to the K20D for resolution. They are both excellent cameras.

By the way, I'm not a Pentax fanboy. I've shot with Pentax, Nikon, Canon, Bronica and Hasselblad over my 35 year career in photography.

I think what this test (and the one with A700) really shows is that there is very little separating these cameras, and the difference is marginal and requires pixel peeping. What is more important is the how the camera feels in your hand, the user interface, the speed/responsiveness, the AF accuracy, and the lenses.

Now what i see and interprid as (pls. correct me if i am wrong) the k20d being more noisy and less colour accurate. reds seem fine, but what about the yellows on the left of the pic, and the wood colour tone. somehow it doesnt look like wb, but i could be wrong...

After handling the d300 last weekend at a studioshoot in not too bright lights, i was so impressed by it ,and had so much trouble handling my k10d da* 50-135 ,couse it hunted for focus all the time, i just coudn't keep up with the model, with the d300 (wich is not mine) i could! I was the only pentax user at the workshop shoot, and proud, but i was not so sure why anymore.

I was hoping for a upgrade, but i guess i might have to sit it out and wait for the next pentax. This is really the first time since i follow the intro of the k20d that i begin to feel a bit disappointed with the pentax system.

Can somebody please bring back my pentax proudness,and hope?!

thanks in advance

Nikon D300: € 1575.00

Pentax K10D: € 615.00

Pentax K20D: € 995.00

For almost €1000 difference with the K10D, the D300 better be better...
The fact that the 2 are even being compared is a compliment to Pentax

I have no doubt the K20D will be able to hold its ground next to the big guns.

this is what i'm seeing:

more noise in the K20D, but much better detail,

and its better to take something out (noise reduction post processing with loss of detail) vs not having any detail to work with at all.

No offense, but in 2008, who's still using dial-up, lol?

Thanks for the side by side comparison shots. Always fun to see how product A stacks up against product B; no matter what the circumstances.

my mom has dial up in russia...

Even though I'm not planning on getting this camera (this year at least) - I have to say that just looking at the ISO1600 images, wow. The Canon has what you think of as noise - different color speckles showing up. The K20D noise looks more like grain than noise - specifically looking at the black area around the "Pop Up Shade" text on top, and the shadow areas to the left of the canned air.

Thanks for making me drool Chris - though if overtime keeps up the way it has been, I might save enough for it in a few weeks!

I still want to know which camera posted the most accurate colors?

I have no way of measuring it besides looking at my laptop monitor. I would say none of them were that accurate, but the K20D was the closest to what the actual item looked like if I held it up to the screen. It's a personal opinion plus the K20D was on bright mode which boosts the color channels a bit.
