If you have a Nikon SLR and you want to use it underwater, you need this lens for macro and all around use. The 105mm lens works too, but is much harder to use.

The depth of field on this lens is amazing. For shooting fast action subjects it becomes a point and shoot. Anything that is about 30cm from the dome port is going to be in focus.

I really like this lens for underwater wide angle, as well as top water. If it were purely for underwater use I would get the fisheye, but the fisheye distorts so much above water. The 12-24 is a better all-around lens. I have heard people say this lens vignettes, but I have not seen it.

The replacement for the D200. It has live view (the ability to see on the LCD what you are taking a picture of). I want one. Bad.

A great little camera that packs 10 megapixels in a compact package. I have one of these. Most of the pictures it takes are tack sharp as long as the light is good.

A slightly higher end compact camera with a huge number of megapixels. More than you really need. Scored very high at dpreview although I have not used it personally. All the compact Canon's are typically excellent though.

The replacement for the SD900. Adds the same sensor as the G9 and image stabilization over the SD900. Very new at this time (January 2008) and no reviews yet.
