The answer, of course, depends on which camera you are using, what objects you'll photograph, and the desired style of your photo. Style: Let's start with style of photo first. If you want a wider angle, curved view, fisheye look, you'll want a fisheye lens. If not, you'll select a rectilinear lens. Some fisheye lenses can capture 180 degree field of view and distort the image. If you're taking a picture of a single shark, for example, a fisheye lens may not produce the most pleasing image. Objects: If shooting large aquatic animals, you'll typically want a rectilinear zoom lens. Because it's difficult to obtain quality photographs from a distance underwater, the focal length will still be fairly short, usually less than 24mm. For smaller objects, you'll typically want shorter focal lengths. Camera: Canon and Nikon have excellent lens choices, but third party lens manufacturers also make great lenses, but are typically less expense. Here's a good lens list for Nikon and Canon: For Nikon: Fisheye: Nikon 10.5mm (cropped sensor) Tokina 10-17mm (cropped sensor) Rectilinear: Nikon 10-24mm (cropped sensor) Nikon 12-24mm (cropped sensor) Sigma 8-16mm (cropped sensor) Tokina 12-24mm (cropped sensor) For Canon: Fisheye: Canon 15mm Sigma 15mm Tokina 10-17mm (cropped sensor) Rectilinear: Canon 10-22mm (cropped sensor) Sigma 10-20mm Sigma 8-16mm (cropped sensor) Tokina 12-24mm (cropped sensor)
