Wide angles are rectilinear. Fisheyes use different designs (4 basic types - orthogonal, equidistant and two others I cant remember) which give much greater field of view.
From the online field of view calculators I've played with even with an impossibly short focal length of 0.1mm you don't get close to 180° FOV with rectilinear.
Pentax's 10-17 fisheye manages 180 on the diagonal, & Sigma do one thats 180 all round.

There are some canikon brand wide angles that have soo much barrel distortion you might be inclined to believe it was a fisheye.....Dangermouse wrote:

Actually this is wrong.Wide angle does eventually become fisheye, although I'm not sure at what point.

some people look at it from the wrong angle...
here it is from somebody that loves video and still photography...
This is what a d-slr can do for the videographer, that is currently hard/impossible/expensive to do with a video camera:
fisheye shots.
Ultra wide angle shots.
super telephoto shots.
Shallow DOF shots. (used to require a special, expensive adapter to mount 35mm primes).
Hand holdable steadycam shots (easy enough with consumer cameras, but pro video cams are huge, requiring dollys and rail mount systems)
High quality images...
Ultra low light shooting..
anybody that can proficiently shoot still and video images is in demand...
Being a still photographer, or a video only shooter puts you at a disadvantage in a world that wants to consume both in any kind of digital multimedia work, which the Web needs badly. There may come a day when people PAYING for work are gonna ask themselves "Why pay TWO people to do ONE job?" With little or thought to the fact that it USED to be TWO seperate occupations.

I gather (IIRC) that you butt out after the first entry and then people will PM you for anything they want. clarifications etc. If you hang about here your judegment may get clouded by the hoots of approval for some images.first question, when does this end?

Science fiction.
Stan Kubric used lacquers and inks in a black pan to create spectacular space scenes for Space Odyssey 2001.
The crew on the original star Trek used pin holes in black sheets for stars..
I made this Martian landscape (chroma key green sky as it was for a video project) with spices (curry, cayenne and also some fireplace ashes) and modeling clay..
I've used bubbles for planets..... the limit is your imagination... pie plate flying saucers welcome.
Your mission, should you choose to accept it, is to photograph anything sci-fi, with a preference towards "Space".

Thanks all for the encouraging words! I am very much in the category of ' little technical knowledge, but know what she likes' . I will give it a try! More than that: I've been collecting and taking pictures of wire and assorted things all evening. Nothing I like well enough so far though. But there's another 18 hours to go, so I hope I'll come up with something. Thx again!

at a Canadian Princess Auto Store. (PowerFist branded at Princess Auto).
$49.00 Cdn
60 bright white leds the light output is fair, appears daylight balanced (will do some tests this week to see how accurate, I have rosco gels to change to indoor color balance) fairly narrow throw, but a diffuser can be easily made..
mounted on a flip or similar bracket....
not dimmible... but appears weather resistant... good for Pentax shooters with weatherproof dslrs....
3 hrs on a charge..
compare to "LitePanels l.e.d. video lights that cost $299.00 and up....
worth looking around for if you are on a budget..
