Once you move up from Compact cameras to interchangeable lens Mirrorless and DSLR cameras, it's all about the glass!
Buying the best camera lenses, and ports to use them in, for underwater photography and videography is a long-term investment. Lenses and ports can be used over and over as you buy new cameras. It's important to plan what lenses to buy and what lens format to invest in. Then buy high-quality lenses and matching extensions, gears and ports as you can afford them.
Most cameras come bundled with an inexpensive "kit" lens. Typically, these lenses aren't wide enough, with focus close enough, or offer the required sharpness to get great results underwater. Their build quality (mount and glass) isn't usually the best either.
The extra expense of extensions, gears and ports for underwater photography and videography can make these "inexpensive" lenses poor investments in the long run. Many underwater photographers end up selling the kit lenses after a short while. They are disappointed with the results, but then are stuck with extensions and ports they can't use.
Underwater we generally want three general focal length ranges of lenses, all with the idea of getting as close to the subject as we can. Water absorbs light, colour and clarity. Eliminating as much of it as we can gives us the best results.
Those three focal length ranges are for ultra-wide, mid-range zoom, and macro. Ultra-wide fisheye lenses yield the best corner sharpness. With the ability to focus within a few inches of the lens, fisheyes are the go-to option for close focus, wide angle photography. Wide-angle rectilinear lenses generally don't focus as close and require much larger dome ports to get the same corner sharpness. They are most suitable for shy pelagics, when having a narrower field of view provides extra reach.
Below is a list of underwater photography and videography lens recommendations. This is not a finite list. If you have others you want to use, check to make sure there are port solutions for them. Older models of popular brands are generally supported and work fine. But those listed here are supported by housing manufacturers and are known to give excellent results.
Note: Most full-frame macro and mid-range zoom lenses work fine.
Please see Port and Gear Chart Links for information about the port and gear options for using these lenses with various underwater housings.
Please Note: The Scuba Doctor does not sell cameras and lenses.
