I can adjust the viewfinder.. I wear glasses..

My question is.. If I take off my glasses and adjust the viewfinder to my unassisted eye.. And focus internally from there, will my end result be clear?.. Or do I have to wear my glasses regardless?.. My perscrption isn't horendous.. around 1.75 on my good eye.. Is that the purpose of being able to adjust the viewfinder?.. If not.. what's it adjustable for?

This usually called a dioptre (or diopter in US) adjustment and is, as you say for people who usually wear spectacles. It replaces your spectacle lens and only focusses the image in the view finder. When that is sharp and clear so is your photo. BTW if someone else uses your camera they will need to re-adjust it to their eye.

Yes, as stated above, the diopter adjustment is to allow you to see the viewfinder image clearly without your eyeglasses.

When adjusting the diopter, look at the fixed readouts (shutter speed, exposure info)of your viewfinder. When these fixed readouts are clear to your eyes, the diopter is properly adjusted.

The diopter adjustment only effects the viewfinder image, it does not effect the image the CCD sees in any way.

I had to sort-of laugh at this post. I think I'm constantly at war with the dioper adjustment on my camera. My problem is that I wear either contacts or glasses, and the dioper adjustment on my viewfinder is difficult to access under the rubber eye cup (mine is removable). Normally I leave it adjusted for my contacts, but on weekends I often don't bother with them and my glasses are transition lenses. When I'm outside in snow, the reflected sunlight turns them really dark so it is hard to figure things out, so have to take off my gloves, remove rubber eye cup, and adjust the viewfinder to make sure that I'm focusing right (I've been using a manual lens mostly since I got the Pentax).With the PentaxI'll sometimes not bother changingit and just hope that thecamera is focused on what I want when it indicatesits in focus.

It's mildly annoying, but if it were easier to adjust I would be just as annoyed when I go to focus and find that I've knocked the adjustment accidentally.
