Due to their short focal length, fisheyes are considered ultra-wide angle lenses. If you take a look at the picture below, you can tell how much of a scene can be captured with a 15 mm fisheye lens as compared to a 24 mm wide angle lens.
As a rule, the shorter the focal length, the wider the angular view, the larger the area captured, and the lower the magnification. To get a better picture of how wide an image can get when using such lenses, in the picture below you can see a comparison between the Nikkor The photographer has used Photoshop to resize and layer the images, and has also defished the fisheye image. As a short note for those new to the fisheye lens usage, defishing means transforming the fisheye image from curvilinear to rectilinear.
No matter if you are a professional photographer or a hobbyist, you can use both types of lenses for the incredible depth of field allowed by shooting at small apertures too.
So, both wide angle lenses and fisheyes can capture broad view areas and provide an impressive depth of field to the pics you take, which translates into sharper images. Although these two types of lenses pose a few similarities, they differ greatly in terms of perspective and levels of distortion.
As regards the potential area captured, a 12 mm wide-angle lens, for instance, can capture a field of view of degrees. Now, if a fisheye lens is defined as an ultra-wide angle lens due to its large angular field and short focal length, a wide angle lens is never a fisheye as it cannot project a degrees field of view.
It also crops in slightly on your photo. Fisheye left. Notice the curved lines. On the right is what a normal wide-angle lens would see. Note the slight loss of field of view, noticeable in the trees on the edges. When I took out the barrel distortion in Lightroom they were basically identical in field of view. Does this digital manipulation cause you to lose resolution?
Used correctly, it can add a surreal aspect, or wildly emphasize your subject. That said, since you can take the fisheye aspect out of the image afterwards, in a way a fisheye gets you two lenses in one.
So what did I pick? I have both, but let me explain! For many of the photo projects I do, there are a lot of tight interiors, like the inside of a submarine, or a castle, that kind of thing. I also have a Sigma 15mm fisheye, with a maximum aperture of f2.
Seems like a rare occurrence to me. Well the fisheye is likely to be more portable and compact, and potentially give you the option to shoot in lower light.

What is a fisheye lens? Fisheye lenses happen to work very well underwater for a couple different reasons: They focus very closely There are few straight lines underwater Using a very wide lens allows to get very close to your subjects, giving your photograph more sharpness, and better colors when lit with a strobe.
Behind a dome port, fisheye lenses perform better optically than regular wide-angle lenses. Properties of fisheye lens: They usually focus very close They are small and light When shooting ultra-wide angle, you benefit from a large depth of field You can get very close to large subjects, maximizing color and sharpness They perform well behind dome ports with good corner sharpness, and they don't need a diopter You usually need at least 2 strobes with good angle of coverage to properly light the entire area.
Tokina mm fisheye and Sigma mm wide angle lens Fisheye lenses and focal length Although people often think of a fisheye lens as wider than a rectilinear lens, it's important to note that at the same focal length, a subject at the center of a fisheye lens will be magnified the same amount as a rectilinear lens. Barrel Distortion When reading about fisheye and regular wide angle lenses, you will hear a term called barrel distortion.
Correcting distortion post process Land photographers will sometimes use software to correct the distortion of a fisheye lens. A fisheye lens is good for: Reef shots Getting really close Divers, models Large wrecks Mantas, whale sharks Schooling fish shots Over-under shots Sharks that come really close Close-focus wide angle of large macro subjects such as large frogfish, rhinopias, large seahorses What is a rectilinear lens?
A rectilinear lens is good for Shots with straight lines where you don't want to see any curves Skittish pelagics, sharks, dolphins, that won't come close Reef shots that are easier to light the entire space Turtles, sea lions Many people use a rectilinear lens underwater, like a mm lens, because they also need a wide-angle lens for topside out of the water use, such as landscape photography, and they can't afford 2 wide-angle lenses.
My recommended lens choices for underwater photograpy: The Canon mm fisheye and Nikon mm fisheye lenses are the best quality full-frame fisheye lenses out there, but you pay a premium for them. Canon mm circular fisheye lens If you own a Canon dSLR, the Canon mm fisheye lens is excellent, and very sharp.
Circular fisheye lenses The Sigma 8mm fisheye lens is a circular fisheye lens.
