I have asked some of these questions earlier and there never was any consensus. I have the Nikon equvalent right now and it is good, the 1.2x magnification helps with manual focusing but the contrast is affected. It is not easy to clean and it seems as uncoated plastic to me. Is the Pentax version better?
I'm lookin' right at it, and I THINK it's glass, but I can't say for sure.
Yes, I can easily blow off dust with a bulb blower or a can of compressed air. (Never use the compressed air on the inside of the camera, but it seems to be okay on the eyecup.)
Does it reduce the contrast? I think it might, although it takes me too long to pull it off and take a look for the sake of comparison. The built-in viewfinder on the K10D is bright and clear. My vague sense is that I have lost a little brightness or clarity (or both) with the eyecup installed. And of course, this means that the small gain in magnification is offset, at least partly, by the small loss in contrast. But as I said in my first post in this thread, I still find it useful if only because it is a more comfortable object to smash my eye up against than the original viewfinder.
