What Lense

[onbelaydave]

Hello,
When you say 14-20mm, you do not mean fisheye lenses right?

Thanks,

Daniel

I think I am going to get a 60MM macro Lense, and either a 16mm fisheye or a 18mm lense. Which one would you get, the 16mm fisheye or 18 mm lense.

You are forgetting the magnification factor inherent in a DSLR. The sensor is not as large as a frame of film so your lens acts 1.5 times longer. On your D100 a standard 20mm WA will actually shoot like a 30mm. To get the actual equvalent of a 20mm WA you will need a 12mm and no those aren't even "fish eye" you would need an 8mm to get a normal "fish eye". Conversely a 105 macro will be shooting as 150mm, a little too long. That's why I suggested the 60mm macro. It will shoot like a 90mm. Also you can use the 60mm behind Ikes dome port and get yourself a small zoom that can use the same port and save yourself a little $

Well, in a RARE case, Nikon has made a zoom that surpasses the optics of a 24 mm prime lens, and arguably down to 18 mm.

If you want the option to change your focal length underwater, this is the wide angle lens for you (but it'll cost you -- over a thousand bucks)
