Hi Will,

glad I could be of some help!

As to your question: if you want to make a photo like that one of the dead fly, then you do need a bellows, I cannot think of any other way to get this high a magnification ratio (I think the eye only measures about a millimeter, which would put the ratio in the order of 10:1 (which means you magnify the subject by a factor ten.) With the other two, just a plain macro lens (and extension tube) would do...

Are these bellows made for the K10D? Do you know of anywhere that sells them or is that something that one just goes into the local camera shop and buys?

As for the extention tubes...I assume these help with closer focusing. These can be bought anywhere and used with a Pentax 50mm 2.8 lens?

The Pentax bellows isn't made anymore, but I guess you can find it fairly easily on eBay.

As for the extension tubes, they can be used with any K-mount lens. You loose automatic metering and AF, but It will work out...
