I did not find the tag for K-m, so I made one by myself based on the first post.

Thanks for all you guys' reply. Sorry I do not have any experience of slr before, now I know this "patterned dots or ridges" on focus screen are intentionaly made to deliver better optical images. And I forgot to mention the canon 400d uses a macro lens which might have larger aperture compared to k-m's kit lens, which could allievate the patterns.
Here I find some good information on the focus screen, some of the picture show clearly the patterns.

I hope so :)
but they are in gray. you can not even notice them when point to general objects. they only show up when shoot very bright objects, like lamp or light.

Got my K-m from prodigital2000@ebay this week. The camera is brand new in box. I checked the shutter actuation is around 200.
When I mount the kit lens and tried to take some samples, I found the viewfinder was generally good. But when I shot at the lamp, the viewfinder show patterned dots in the whole screen, especially zoomed in with tele focal length. I switch to another lens, the same prob. Then I tried dust remove function and took a picture of white paper. There was no dust alerted, though.
Now I think the dots should come from the optics in viewfinder not the ccd and lens. Does anyone encounter the similar problems or have any suggestion? If this is a defect, I may return this and get a exchange in 14 days. I check a canon 400d from my friend and it's clear all the time (including shot at the lamp).
Thanks,
Ping

Just see this thread after I start a biding of A 50/1.7 on ebay.
From the OP's profile, I see you also own the f1.7 before. Since this will be my first prime lens, could you give me a comparison with this f2.0?
Thanks :)
