Fisheye lens adaptors

[lukebl]

Has anyone had a go with one of these cheap fisheye lens adaptors, which screw into the front of your existing lens and effectively halve your focal length?

I think the statement that they're 'GUARANTEED NOT TO DISTORT THE PICTURE' is worthy of investigation by trading standards, but at only £21.95 inc. postage, they must be worth a punt for a bit of fun imaging.

Stiuck on the front of my QHY8 + Nikon lens, one of these super wide angle lenses. They work, but some real distortion at the edges.

Super crazy startrails from kelling last year

Hmmm... Guaranteed not to distort the picture?

Perhaps not even worth £21.95

Well, I picked up one of these adapters off the well-know auction site for just £12.95 new. Hardly Leica optics, but probably worth it for a bit of fun. OK if you stop the lens down a bit. Shame it doesn't do a complete fisheye.
