I'm thinking about buying a fisheye lens for my Nikon D40X and I was wondering what the difference is between the 0.22x and a 0.42X here are the links...

I believe that it's the magnification. These do not look like and actual lens but more like an adapter that sits on a lens.

Most actual fisheyes will have a focal length designation and an aperture setting.

Something like Peleng 8mm f/5.6.

There's no focal length rating or aperture rating for either of those, just adapter ring sizes and a magnification number - 0.22x and 0.42x

Take those and multiply which ever lens you inted to fit it on by that number and that's your focal length. On a 20mm lens, it will be 11.6 with the 0.42x.

Also keep in mind, these will probably degrade image quality as it's an extra layer of glass and will also cause less light to pass through. If you want a cheap Fish Eye LENS, look up Peleng. It's fully manual, but they're like $250.

Actually, the Peleng should give a full image or nearly full on a Digital Nikon. They have a 1.5 crop sensor. I've seen numerous pics from these on the Canon 1.6 crop sensor and they're full pic's, with just some vingetting when shot wide open...most people say to use these at like f/6 or f/8 for best results.

Not a bad lenses and if you shoot manual mode enough, you should know about metering enough to use one of these. Not bad for $250.
