I shoot with an Olympus OM-D E-M1 in a Nauticam E-M1 Mark II housing, and whenever I am shooting wide angle I use the Olympus 8mm f/1.8 fisheye lens. I run into a lot of people who either don’t use a fisheye lens at all, or who think it is a specialty lens that you only use for big things like mantas, whale sharks or humpbacks.

Yes, fisheye lenses are definitely the best for giant subjects like that, but they are incredibly useful for a lot of other situations as well. Although fisheye lenses are used more as art lenses or for niche applications on land, underwater, it’s a different story. Rather than the fisheye being the specialty lens, underwater I think of the fisheye lens as the default wide angle lens, while non-fisheye wide-angle lenses are the specialty lenses.

Fisheye Lenses 101

The first thing to understand about fisheye lenses is what sets them apart from normal wide angle lenses. The big difference is that they have an enormous field of view – typically, 180 degrees! Compared to the 75 – 114 degree field of view of the 7-14mm f/2.8 Olympus wide angle lens, the 8mm fisheye’s 180 degree field of view is much more (plus it is significantly smaller and cheaper).

To be able to create this massive field of view, the fisheye lens warps the image, with the warping most pronounced at the edges of the image. For more of a comparison between the two types of lenses, check out this very detailed article on fisheye lenses vs wide-angle.

Wide Angle Shooting Basics

When shooting wide angle underwater, you always want to be as close to your subject as possible (while still having a nice composition). The closer you are, the less water between you and your subject, meaning the subject is sharper. Additionally, the less distance your strobe lights have to travel between your camera and the subject, and then back to your camera, the brighter and truer the colours will be.

If your strobe light has to travel 4 ft to the subject and 4 ft back, you will have a lot less color (especially reds) than if your strobe light only has to travel 2 ft in each direction. Of course, the fisheye lens is the best at getting you as close as possible to your subject. Additionally, the barrel distortion of the lens, which can be very difficult to use above land, works great underwater, where there are very few straight lines.

Below is a collection of my favorite shots taken with my fisheye lens, as well as some explanation about why the fisheye made them so great.

Manta ray belly taken at Manta Point, Nusa Penida, Bali. The water was pretty murky there, as it is at most manta dive sites. The only way I was able to get the belly so sharp and detailed, and have the nice lighting, was by shooting with my fisheye lens in my underwater housing and being only about 3 feet below this manta as it passed over me. With a wide angle lens, I would have had to be much further away to get the whole manta in the frame, meaning less clarity, more backscatter, and poorer lighting.

Octopus in Manta Bay, Nusa Penida, Bali. The fisheye lens allowed me to get very close to this octopus, bringing out the detail in it, but also to include two dive models in the photo, and bring the sun into the composition. I did this by getting low and shooting up. Without a fisheye lens I would have had to be further back from the octopus just to get the two dive models in the photo, and would not have also been able to include the sun. There was not enough space to get that far back and that low for the same composition. Without the sun, this photo loses an important point of interest, and becomes just a decent photo rather than one that really pops.

Coral at Crystal Rock, Komodo. The fisheye lens allowed me to get very close to the coral and rock, within less than two feet. This meant I could stop down my camera to f/18 and max my shutter speed at 1/320s to bring out the details in the sun, but I was close enough to my subject that I could still light it very brightly with my strobes. When I tried this shot 2-3 feet further back, which is what I would have had to do with a wide angle lens, my YS-D1 strobes at maximum power could not illuminate the coral and rock properly.

School of fish beneath the jetty at Tetamanu Village, Fakarava South Pass, French Polynesia – one of our 5 “scuba diving bucket list” destinations. Without my fisheye lens, there is no way I could have been far away enough from these fish to get them all in the frame with a nice shape, and close enough to light them properly with my strobes. This shot was taken about 3-4 ft in front of them. The added bonus of the fisheye is that with the exaggerated perspective it creates, it amplifies the “3D” effect where it feels like the fish in the water are coming right at you out of the image.

A beautiful reef scene at Batu Bolong, Komodo…one of the nicest sites I have ever dove. Same as above…sun rays, beautiful colors, sharpness…only a fisheye can start to do justice to a spectacular reef scene like this. No matter what I did I could not get a photo which really did this site justice, but at least the fisheye gave me a fighting chance.

I have lots of other examples, but I think these shots give a good idea of some of the reasons why I love shooting with a fisheye lens, and why if you don’t have you, you really should pick one up for your rig – assuming your underwater camera supports a fisheye lens.

Which is Right for You?

When people are just getting started and they ask me whether they should get a fisheye lens or a wide angle lens, I ask them this question. Do you want to be able to get a lot of decent photos, especially of skittish pelagic subjects? Or do you want to get a lower number of decent photos, and have some frustrations with skittish pelagics, but instead be able to get some really amazing, extraordinary shots?

If you want the former, then go with a plain wide angle lens. But if you want to get those shots that make people go “Wow” when they see them, the shots that can win awards, and are OK dealing with some frustrations, then it’s fisheye all the way!

Sevengill sharks started appearing in the San Diego area a few years ago, and their numbers appear to increase each year. They are most commonly seen in the Point Loma kelp area, and the La Jolla cove. There have been several sightings in the “cove” during the last couple of weeks, including the 2 sharks in the above photo taken yesterday by Scott McGee (cropped, taken with Nikon D800, Ikelite housing).

Here is an exciting sevengill shark video taken a few days ago by Scott McGee, in La Jolla cove.

This video below was taken two days ago by Rod Watkins at the outer reef of the La Jolla Cove Ecological Reserve.  A sevengill shark can be seen at the very beginning of the video and again at the 2:23 mark.

The Broadnose Sevengill Shark, Notorynchus cepedianus, has been seen in increasing numbers in the San Diego area since 2009.  No one is really sure why the number of interactions with these sharks has been increasing but theories include everything from deep ocean currents to ocean currents due to global warming. The sharks seem to make an appearance every couple of years. Their max length is 9 ft  and they are opportunistic feeders, going after other sharks, rays, bony fish, and sea lions. There is a good article here on their return to San Diego.

Mike Bear, a REEF surveyor, has set up a website (http://sevengillsharksightings.org) to act as a central repository for data and submissions on these creatures.  If you’ve managed to catch one of these on film or video, be sure to submit it to the site to help with possible identification using the dark patterns on their backs as unique identification markers.

Here are some underwater photography tips for the sevengill sharks, courtesy of Scott McGee, who has had several encounters with them, including one recently.

• They are curious and aren’t afraid of bubbles. I know this because my backup regulator was bubbling constantly through the whole dive and it didn’t deter them. Maybe it even attracted them.
• They make multiple passes. On my first encounter in 2009 off Pt Loma, the same shark did 3 obvious passes by us and upon reviewing photos from earlier in the dive, it was lurking in the shadows before then. At La Jolla Cove recently, there were at least two sharks that did multiple passes.
• Sevengills usually swim near the bottom, so in order to get better shots, you’ll want to be on the bottom and angle up a little. Be aware of the difference in lighting at the bottom vs looking up towards daylight, and set your camera to be a little underexposed. It’s easier to lighten the dark areas than correct for over exposure.
•  Sometimes they’ll swim straight at you and veer off as they get closer. If you follow them, they can get skittish and speed off.
• The only aggressive behavior I’ve heard of was from a spear fisherman who had dead fish on a stringer attached to his body.
