Jon,

Try a Pec-Pad on a popsicle stick and gently start from the rear of the screen and pull front. If the dust is between the screen, and If you're very careful you could open the focusing screen compartment and remove the screen for cleaning, but I don't recommend this unless you have done it before. If there is a camera shop in your area you could ask them to do it for a small charge. I tried to clean mine once and ended up replacing the screen because I touched it with my fingers and the oil from the skin ruined the screen. I know the screen can be replaced rather cheaply by Pentax ($11.95 is the cost of a new screen) but I would rather pay a small fee for the cleaning then to have to wait a few days for a new screen.

Hi, guys!

I'd love to clean my K100D's Focusing Screen but I'm afraid to damage my camera. I've tried and tried to no avail.

At the risk of sounding awfully dumb, just how is that tab pushed? Up? In?

If you have time, would you post images of the Focusing Screen and Clip outside the camera?

Thanks! I appreciate your help and the information in this post!

I managed to remove the focusing screen and clean the material from behind it with VisibleDust's Sensor Brush.

Unfortunately, as soon as I took a picture, more material reappeared.

Talk about frustrating. I'm debating whether to try it again or have the cleaning done professionally.

I had replaced the focusing screen of my K10D with a Katzeye screen, and upon reassembly I had a piece of black lint perpendicular to the split of the split prism circle, practically the diameter of the circle. Any other part of the screen, I probably would have left it alone, but here it was totally unacceptable.

So I took the screen out a second time, blew it off, and reassembled. The lint was still there. Took the screen out a third time, blew it more (and on both sides), reassembled, and everything was now AOK.

Glad I did it, and seems to be not particularly risky if you're careful.

I had a piece of lint on my focusing screen that bugged me. I put my camera into Sensor Cleaning Mode but I never could blow it out. Then it occurred to me to just take the lens off and blow with out putting it into Sensor Cleaning Mode (leave the mirror down). That did the trick.

I probably just got lucky, but if you're blowing it out, try it first w/out locking up the mirror.

Ugh finally! I got the crap off my focusing screen. but I think I slightly scratched the screen a bit. I went from a half a dozen bits of dust to one + a thing mark in the corner.

Oh man, my fingers where trembling so bad. Halfway into the procedure, I blew out the dust and then forget which way to put the viewfinder back. There's a matte and glossy side and I thought the glossy part was facing inside as to not get scratched, right. But then I checked the photo and realized at the glossy bit was facing out...omg...not doing that again!

That will be annoying, but at least you didn't break or drop it. You would be a little more broke.

FWIW, Pentax makes a "pincette" tool which it includes with all of its optional focusing screens. It appears to be a combination tool to spring the retaining clip and hold the screen by its tab.

AFAIK, Pentax does not sell it separately. So this past weekend I ordered an old PZ-1P screen from Cameta for $9.95 to get this tool (plus a nice included case for storing either my Katzeye or original screen). I'll be discarding the PZ-1P screen unless someone wants it.

Hopefully, this pincette should make removal, exchange and cleaning of the focusing screen a lot easier.

The focusing screen attracts fingerprints much too easily, too.

Touch it once and you see them forever looking through the viewfinder.

Who knew having a digital SLR was going to be so much fun?
