Eye piece blanking
Light will enter the eyepiece if you're doing long exposure shots so it is important that you keep it covered.

I use a bit of black plastic cut from an old tape box which just slides under the rubber surround
You can check out how much light gets in by taking two shots, one with one without blanking.
Incidentally if I'm taking a low level shot (not looking through the eyepiece) by estimating the shot I usually put my thumb over the eyepiece.

I don't use the Penjtax eyepiece as it doesn't fit the K-5.

Are you sure? The same "Finder Cap" fits both my K-5 and K10D. And also my ME-Super and Super-A (and K-30, before I sold it).
You have to remove the rubber eye piece, then slide in the cap in its place
Part number 31011. (Supplied as standard with the K-5 & K10D, but an optional extra on the K-30).
You can see some of my photos here if you are so inclined

Does anyone use the Pentax Eyepiece cover when using a tripod?
Does extra light enter the camera and change the metering,or was this on 35mm cameras only
Yes it does.

Blu tack for me.
I would be worried that Blu Tac might damage the Anti Reflection coating on the eye peice

how much light can actually get past the raised mirror anyway?
Small amounts, but when you're doing a long exposure this can make a big impact on the final image. A small amount of light falling on the sensor for 2 to 3 minutes for example can be clearly seen as streaks in the image.

I chuck an old black t-shirt over. It's always in my camera bag.
