Looking for a super wide-angle lens (M42)

[TheReef]

Hi All,
I'm looking to buy a super wide angle M42 lens (less than 24mm equiv and not fish-eye).
It will be used on a digital body. I essentially want something wider than the 18mm kit lens for land/seascapes.

I'm wondering if there is anything cheap out there (ie <$100), brand doesn't concern me, does anyone have any recommendations?

6mm f2.8 fish eye lens

Found this on ebay and remembered your question. It's not the cheapest of lenses, but it IS wide ...

It fits Nikon F mount though.

Wow, I've never seen anything like that before.

A little out of one's budget through

To broaden my options, could I be mounting old super-wide Nikon/Canon/Olympus lenses onto M42, or even the K mount with some adapters?

I know of a M42 to Nikon F mount, to use M42 lenses on Nikon bodies.

You can have a try, wether the old German Practicar lenses fit on your body. I revisited them on ebay, as my first 35 mm SLR was a Practica camera.
The lenses were sold under the labels Practicar, Practica, Pentacon, Zeiss for Practica.
They come with M42 mount and are a steal on ebay.
I saw 500 mm f5.4 lenses for 150,- EUR

Next time, I am in Germany, I get myself a M42 - Nikon F adapter and buy into some of this glass.
