Just wanting to vent a little bit here as this will be my first time with a decision like this. Sorry if this is in the wrong section and if I bore you all to death.
Never had a problem with any of my Pentax cameras before from the K100d Super to my K-5. I have a K-3 that I bought last April and around December had a piece rubber foam break off leaving black "strands" of dirt BEHIND the focus screen that just won't stop coming. Almost every week now I'm having to blow it out. I'm nearly tempted to just remove the rubber foam completely!
I also have this tiny little speck that won't come off the sensor. Not sure what it is but it just won't come off. When I do dust alert it doesn't see it and my sensor shows up as clean but I see it (although barely visible and you'd have to really look for it) in all the F22 tests I shoot. I do sometimes shoot at F16 and I can barely see it under the same test against a green screen or something. If it wasn't the Prestige edition I'd almost certainly just sell the camera, cut my losses, and just buy another one but I'm one for unnecessary sentimental value.
So one thing I wonder is would it void my warranty if I used a sensor cleaner to try and remove this one little speck? For reference, I used Visible Dust and other than this one tiny speck not going away this product is awesome.
Hopefully the viewfinder assembly is covered as the foam rubber should not have randomly broken up the way it did!
I don't have any photoshoots until March so I figured I'll send it it now and hope to get it back before then. And hopefully don't have to pay much or anything...
