Fisheye Adaptors?

Optically they are usually quite poor with loads of colour fringing and softness- still if you're on a budget they can still give interesting shots you wouldn't other wise achieve.

Here's a photo I took using one bolted onto a 24mm wideangle lens. As you can see it will take in about 160 degrees of sky!

I hate those fisheye lenses, with a passion.

Poor quality and has that terrible black boarder round it. Real fisheye lenses don't have that and, together with the image quality, make them a far better alternative. Of course you pay more, but the more you pay, the more you get.

If you want full 180 degree coverage there's no getting around the black border bit. Some semi-fisheye lenses do 180 degrees across the diagonal (my Sigma 15mm does for instance) but these lenses are only semi-fisheye. True fisheyes are always circular.

There are reasons for needing full 180 degree, circular coverage (or even more with some lenses!). They are mainly designed as scientific rather than artist lenses- though they could of course fall into the wrong hands! 180 degree fisheyes are used by meteorologists to monitor cloud cover and by astronomers for real widefield shots.

Here's some examples photos I took requiring full sky (read circular) coverage of an auroral display in 1992. They record the aurora covering most of the sky. That's not possible with a 180 degree diagonal lens.

I found another good 180 deg fisheye astronomical photo here:

Wow! I wish we had dark skies like that in the UK!

Mind you- I notice a bit of light pollution on the left hand side.
 
Oh right didn't realise that.

I still think that the semi-ones like the Canon EF 15mm Fish-Eye f/2.8 are much nicer. Just can't stand the whole black thing, looks rubbish IMO.
 
DONT GET THOSE FISHEYE ADAPTORS.

so s***t really. dosen't foucs, mad vig and a waste of money. Just save up and get the right fisheye lens for your camera. Plus those adaptors look so rubbish on your camera as well. Please dont :(
 
Here's a proper fisheye lens- the Nikkor 6mm with 220 degree field of view!

If you could ever find one for sale it would cost a few thousand!

Cheaper is the Sigma 8mm 180 degree (circular) fisheye around 300 pounds

I used one of these Jessops 0.4x for my pictures:

As has been said - poor image quality but okay for the few occasions you'll use it -you'll get bored with the effect quite quickly.
