I might be totally off track with my understanding of ISO, but what is the point of taking shots in good light at high ISO's to check for ISO performance?? (this is not related to the last post, but to several others in this thread)
I'd rather see pics in very low light at high ISO, as that is where I'd actually like to have good high ISO performance..

Although you wouldn't be as plagued by visible shadow noise at a sports event, a dark jersey, the distant darker background can still look pretty bad based on how much noise there is in a picture.

A lot of great work in the thread

As I find myself shooting at higher Iso, without flash, the K20 is really tempting over my K10

Got chance to shoot a Internation Badminton Open a couple weeks ago. Here are some of what I got. All shots are straight out of the camera in JPG, AFC w/ K20D+FA*80-200, only resize and applied abit USM.

ISO1600 ones:











Frank what aperture did you take the badminton shots at ?
I see that a lot of our Danish champions were at the event

Very good real-world examples.

If this quality is acceptable to you, that's is what matters most.

BTW, I am quite certain that your examples demonstrate that ISO 1600 is better than what film could do at ISO 800. I have no film examples with me but I'm pretty certain about this.

I'm going to go out and try the high ISOs for myself. I'll be back later.

I have seen some really nice pictures from people here using high-iso on the k20d. There is still some thought that the k20d does not perform well at ISO above 1600 (in part due to a popphoto review that characterized the k20d as "unacceptable" above iso 1600)

Well I thought I would start a thread for people considering buying this camera to view, and see just how wrong this assessment is. The idea being that we pool the best of these example shots in one thread.

Only above ISO1600 please. The idea is good examples of performance, and no extreme crops. (People that want to agree with "unnacceptable" can start thier own thread ) Just good useable everyday pictures like most people take or would like to take.

I'll start off:

ISO 2200


ISO 4500


ISO 6400
ISO 2200, 4500 & 6400, I'm guessing your using the TAv mode? My K20D tops out at ISO 1600 whenever I use the TAv mode, where do you set to a higher ISO? (newbie question)

Here's one I took at ISO 1600.

No, none are in TAv mode. Some are in Tv and some are in P. You can set a fixed ISO by pressing the OK button and spinning the back wheel. Also, I think Auto ISO default tops out at 1600. You can change that by using the fn button and then set it to whatever you want.

Just a reminder everyone that we would like to focus this thread on shots taken above 1600 iso.
I have the OK button with the front dial set to change the ISO settings, but they are 100, 200, 400, 800, 1600, 3200 & 6400. The only other setting I can get different ISO numbers are in TAv mode i.e 560 and 1100. I just tried the P and Tv modes and I never got any ISO numbers other than the above ISOs.

Never mind. I think I've figured it out.

Jewelltrail: You are, of course, correct: decrease the shutter speed. Thank you.
I've also wondered about this. Instead of taking multiple exposures, why not just take one with lower shutter speed and lower ISO?

Also, if you "expose to the right", you basically have to reduce your shutter speed, so why don't just reduce ISO instead?
