Thank you Tim, still leaves me with the question what's right
How would you've phrased the question?
You see I use you've again

And coatings most likely but no one is sure about that.

They say 2/3th of the new price, at least I think that is/was the rule.

But Paul photobucket is very simple.
Upload the photo, copy the IMG link and paste it in your comment, that's it.

Here are two tutorials that can help you.
USM - link
High-pass - link

Which one is the best depends one your photo, sometimes USM works better and other times high-pass so I suggest learning them both, you can even combine the two.

ps. in the tutorial he talks about how you can't use layer to control USM but you can.
Put the blending mode on Luminosity and with the opacity slider you can let the original photo come through more so effectively lowering the effect of the USM, it's not perfect though.

Yes Matt that's what I mean.

I see I'm mixing things up.

I thought that F lenses go onto the F mount but that isn't true, AF lenses go onto the F mount
Do you get me?

Basicly I thought
F mount = F lens
That's not true it's
F mount = AF lens
AF mount = F lens / FA lens

Sighs, Pentax didn't thought that one out much

Hefty, you can test it.
Aim the camera at something without a shining surface, so something that shouldn't effect the exposure when you turn the filter and turn the filter.
If the exposure change when you turn then it doesn't work with the light meter.

Cedric already tested it once with the K10D and the K20D link

Matt I don't mean the power zoom contacts it are the other contacts I'm worried about because they are on the opposite side of the mount.
If you mount an F lens on a KAF mount, non of the contacts will make contact.

If you use photobucket it's quite simply, they provide the link you need with the codes so all you need to do is copy and paste.

Will F lenses work, the mount looks quite different?
