A few minor issues with open box K-r

Greetings everyone - I'm so happy to have joined the world of DSLRs! I had 35mm film SLRs (including a K-1000), but my digital cameras have always been bridge cameras. I finally decided bridge cameras weren't living up to my expectations and saved my pennies for a new K-r. I bought it with the 18-55 and 55-300 kit lenses for a reasonable price from the Amazon Warehouse to save money. They claim that warehouse items may be new or may be gently used, but that they are all thoroughly inspected before being resold.

Generally speaking, the camera works great. I love the K-r and have already taken several "keeper" shots in just the first few days I've had it. However, there are a couple minor issues with it that I'd like to get your opinions on.

1) I can see fingerprints through the viewfinder. I have checked, and the fingerprint is not on either of the lenses, nor on the mirror, nor on the viewfinder itself. I can only assume the fingerprint is on the white plate (or chip or pad or whatever you call it) that sits directly above the mirror. Is it safe to clean this plate (or whatever it's called)? And if so, how do I go about doing so?

2) Inside the body is a thin foam gasket (I don't have the camera in front of me at the moment, but if memory serves, this gasket is only on the top of the interior of the body). I don't know what this gasket does, but I'm guessing weatherstripping or something. Anyway, that gasket is a little bit frayed. Is this something I should be concerned about?

Functionally, I have not had any problems with the camera, but these two little issues are bugging me, so I'm wondering if I should send it back and try for another one, or if these things are fixable/ignorable.

Any advice appreciated.

Thanks!

That would be the focusing screen. They're made from very soft, easily scratched material and I haven't a clue how to safely clean one. Maybe a sensor swab? Doing anything to it would be a risk of scratches. Hopefully someone else here will jump in with the proper method of doing this. I do know that quite often people accidentally scratch their screens just removing or inserting them, like when they buy a Katzeye screen.

Your second issue isn't familiar, I'll take a look at mine and edit this if I have anything to add.

The focusing screen will display concentric circles that look like fingerprints but are actually due to the fresnel design.
They are normal.
I can't answer the frayed gasket question as I have a K-x and am not near it sorry.

The focusing screen will only look like that at small apertures- above F4 you should never notice it.

OK, thank you folks. I pulled the lenses off and stared through the viewfinder for a while last night and I see what you mean about the concentric circles on the focusing screen. So I guess they are not fingerprints after all. That makes me feel better! Not sure what, if anything, to do about the frayed gasket. I could put a tiny micro-dab of superglue in there to hold it together, but I'm not sure that's necessary, as it doesn't seem to be getting any worse, nor affecting picture quality as far as I can tell. It bugs me that my "new" camera is less than perfect right out of the box, but if the only thing wrong with it is the frayed gasket and it's not causing any problems, then I guess I should be happy because I got a pretty good deal and it seems perfect in every other way.

I'm loving my K-r! I just wish I hadn't sold my K-1000 (and all the lenses I had accumulated with it) many years ago. Who knew I could have used them now!

Any chance you could post a picture of this gasket, showing the damage? I'm genuinely curious.

The gasket is the landing zone for the mirror when it flips up its not meant to be air tight, only light tight.

I wouldnt use super glue near a camera. The emissions as it is drying tend to fog up glass with a white residue that cannot be removed.

Also it will also make the gasket hard as a rock which will affect the mirror as it hits it, with the very least being a change in sound, worse being a broken mirror.

Post a picture.
