Dirty Viefinder on new K-30?

Hi, I just received my new K-30 in the mail yesterday and so far I like it a lot. However, I noticed today while taking some landscape photos that the viewfinder seems to have a sort of dirty speckled look to it. It reminds me of a matte computer screen almost. I'm not sure if this is normal or intentional for framing reasons or if I got a defective body. The dirty pattern doesn't show up on my images and I don't see anything on the mirror. I've cleaned the viewfinder and the lens but I still see it. Would love to know if others have clear viewfinders so that I know whether I should try to get a replacement from Pentax

Are you using a slow lens (F5.6 and below) in low light? If so, it's normal to see fingerprint looking patterns in the VF. If not, try using a blower on the focusing screen to eliminate any dust.

That's why I love my S-type replacement screen, no fingerprint look and much better focusing with fast lenses. https://www.pentaxforums.com/forums/pentax-k-5/194148-best-90-bux-i-have-ever-spent.html

I'm just using the kit 18-55 zoom lens WR that came with the camera. I tried different apertures but it didn't seem to matter. The pattern isn't a fingerprint so much as a very fine black sandy pattern. Its most noticeable when imaging a large uniform color like the sky. the pattern is so uniform that I think it may just be an aspect of the focus screen. Perhaps because this is the entry model Pentax skimped a little on the screen and it isn't crystal clear as I'd expect. Or if could be a Pentax thing as I've only ever shot Canon before.

The viewfinders of the K30 are dirty because of the dust which is from the factory. When you use the camera the dust is moving... There are many users complaining from dust inside of new cameras so my guess is that the quality control is ... almost none .

That's how the screen looks so nothing "wrong" with your camera. Change the screen to another if you want a different kind.

I just talked to the Technical Service at Pentax online and they said that what I'm seeing is not dirt but that the focusing screen is "textured". He didn't have an explanation as to what advantages this provides but he said that most cameras have a textured focus screen. I'm satisfied with his answer but I'm curious if the screens at focusingscreen.com are also textured.

OK, thanks VisualDarkness. Guess I'm just overly critical / paranoid.

It's normal for Pentax, my K100D was the same. I believe there are sound technical reasons for it to have this grain - it's good for something
