k-r viewfinder problem

Product: K-R
On the viewfinder pointing at the image for shooting we see concentric, overlapping signs like leaves of a flower.
- It's not disappearing changing the lens.
- It's not appearing on the photograph taken.
Is that a mirror/prizma problem?
Thank you!

Most likely this is just the minute size pattern on the focus screen combined with sharp eyesight.

They're simply Fresnel's lines, imho... you should see that pattern when your viewfinder is well calibrated..

Ovim...

Yes, you are right. I simply did not look at this... funny that.

Well, the OP has his answer. Twice.
