2Types of Wide-Angle Lenses for Diving
Rectilinear wide-angle lenses are designed to render straight lines as straight, minimising the barrel distortion often associated with wide views. These are the most common choice for general underwater photography, ideal for capturing reef scenes, shipwrecks, and large marine life where preserving natural geometry is important. They offer a balance between a broad field of view and accurate representation.
Fisheye lenses are an extreme type of wide-angle lens, typically offering fields of view from 100° to 180° or even greater. They deliberately embrace barrel distortion, creating a characteristic curved, spherical look. Fisheye lenses are excellent for super-wide close-focus photography, allowing you to get very close to a subject while still including a vast background. They are also popular for creative shots and capturing entire schools of fish or vast wrecks.
Some lenses are designed with macro-capable wide-angle features, allowing you to focus incredibly close to subjects while retaining a wide perspective. These can be particularly versatile for capturing small subjects within their wider environmental context, blurring the line between macro and wide-angle photography.
3Comparing Wide-Angle Lens Types
| Lens Type | Focal Length (Full-Frame) | Field of View | Primary Characteristics | Liveaboard Relevance |
|---|---|---|---|---|
| Rectilinear Wide-Angle | 14-35 mm (0.5-1.4 inches) | 60°-114° | Straight lines appear straight, minimal distortion, natural perspective | Excellent for general reefscapes, wrecks, large marine life encounters |
| Circular Fisheye | 8-10 mm (0.3-0.4 inches) | 180°+ (circular image) | Extreme barrel distortion, full circular image, ultra-wide perspective | Creative shots, super-wide close-focus, capturing entire environments |
| Diagonal Fisheye | 15-16 mm (0.6 inches) | 180° (full-frame image) | Extreme barrel distortion fills the frame, can be rectilinearised in post | Versatile for wide-angle close-ups, schooling fish, large subjects |
| Ultra-Wide Zoom | 10-24 mm (0.4-0.9 inches) | 84°-110° | Offers flexibility in focal length, slight distortion at widest end | Good for varying conditions and subject sizes without changing lenses |
4Optimal Use and Techniques Underwater
Getting close to your subject is paramount when using a wide-angle lens underwater. Water absorbs light and reduces contrast, especially over distance. By minimising the water column between your lens and your subject, you reduce backscatter and maintain colour vibrancy. This often means getting within a metre or even closer for the best results.
Utilising external strobes or video lights is crucial for bringing out colours and adding definition to your wide-angle shots. Position your strobes wide and slightly behind your housing to illuminate your subject evenly and reduce backscatter. Experiment with strobe angles to achieve desired lighting effects, from flat illumination to more dramatic side lighting.
Composition with a wide-angle lens benefits from strong foreground subjects, leading lines, and a clear point of interest. Look for interesting coral formations, divers, or large marine animals to anchor your composition. Remember that the wide field of view can make distant subjects appear smaller, so consider your framing carefully to maintain impact.
5Wide-Angle Lenses on a Liveaboard Trip
A liveaboard trip provides unparalleled opportunities for wide-angle photography. With multiple dives daily at diverse sites, you'll encounter everything from expansive reef systems to large pelagics, making a wide-angle lens an essential piece of your gear. The convenience of a liveaboard means you can easily switch between lenses or use multiple camera setups without the logistical challenges of shore-based diving.
Many liveaboard itineraries specifically target destinations known for their dramatic wide-angle potential, such as Manta Ray cleaning stations, schooling hammerheads, or vast pristine coral gardens. Having a wide-angle lens allows you to fully capture the majesty of these experiences, creating images that truly convey the scale and beauty of the underwater world.
While on a liveaboard, consider dedicating dives specifically to wide-angle photography. This allows you to focus on the techniques and compositions best suited for the lens, without the distraction of trying to capture macro subjects simultaneously. Take advantage of the advice from onboard dive guides and fellow photographers to refine your skills and make the most of your wide-angle setup.
6Common misconceptions
Myth: Wide-angle lenses are only for landscapes. Fact: While excellent for landscapes, wide-angle lenses are also ideal for close-focus wide-angle photography, where you get very near to a small subject but still include its environment. This technique is popular for showcasing subjects like anemonefish in their coral home or a nudibranch on a vast sponge.
Myth: You can only shoot huge subjects with a wide-angle. Fact: Wide-angle lenses excel with large subjects, but they are also fantastic for capturing groups of medium-sized marine life, like a school of barracuda or a formation of eagle rays. Their ability to show context makes even smaller subjects more impactful within a wider scene.
Myth: Wide-angle lenses are difficult to use underwater. Fact: While they require practice, the main challenge is getting close enough to your subject and managing lighting. With good buoyancy, proper strobe positioning, and an understanding of composition, you can achieve stunning results even as an intermediate photographer. The simplicity of getting everything in focus can actually make them easier in some scenarios compared to macro lenses.
FAQ
What is the best wide-angle lens for underwater photography?
The 'best' lens depends on your camera system and photographic goals. Popular choices include rectilinear wide-angle zooms (e.g., Tokina 10-17mm fisheye, Canon/Nikon 8-15mm fisheye, or rectilinear primes like the Sony 12-24mm) for their versatility and image quality. Research compatibility with your camera and housing.
Do I need a dome port for a wide-angle lens?
Yes, almost all wide-angle lenses for underwater photography require a dome port. A dome port corrects the refractive effects of water, preventing the magnification and field-of-view narrowing that would occur with a flat port, ensuring your wide-angle lens performs as intended.
How do wide-angle lenses affect colours underwater?
Wide-angle lenses themselves don't directly affect colour, but by allowing you to get closer to your subject, they help reduce the amount of water between the lens and the subject. This minimises colour absorption by water, especially red and orange, helping you capture more vibrant and accurate colours, particularly when combined with strobes.
What is 'close-focus wide-angle' photography?
Close-focus wide-angle (CFWA) photography is a technique where you get very close to a foreground subject (often within centimetres) using a wide-angle lens, while still capturing a broad background. This creates a dramatic perspective that highlights both the subject and its environment.
Can I use a wide-angle lens for video?
Absolutely. Wide-angle lenses are excellent for underwater video, allowing you to capture sweeping vistas, large animal encounters, and dynamic scenes without constantly panning. Their wide field of view helps stabilise footage and provides a sense of immersion.
What aperture should I use for wide-angle underwater shots?
A common aperture range for wide-angle underwater photography is f/8 to f/16. This provides a good depth of field, keeping both your foreground subject and background in acceptable focus, while still allowing enough light to reach your sensor. Adjust based on available light and desired effect.
