Kraken Macro Snoot Light Review


Shining a ray of light on this new small light.

Kraken’s new Macro Snoot Light is an easy way to get into the use of directed light for underwater macro photography.
Snooting refers to the control of light through a cone, or light shaper, so that it’s used as just a small beam for more dramatic, lighting solutions. In studio lighting photographers use all sorts of shoots, barn doors, grates and more to achieve interesting light qualities.

It’s been very popular for some time in underwater photography to use snoots on strobes that can be aimed, and made larger, smaller, or even shaped. Products such as the 10Bar Laser-aimed Snoot, or the Retra Light Haping Device have quite a bit of creative flexibility built into them.

However, these are fairly long and bulky on the end of a strobe to use, travel with, and are more expensive. It also takes quite bit of time to acquire the subject, aim the snooted strobe, adjust exposure and take the shot you want.

Kraken’s new Macro Snoot Light is small and lightweight. It comes in a bag with a rechargeable battery that you can just plug in to recharge - no external charger is necessary. Like all Kraken lights, it has robust construction and is double oring sealed.

I tried this macro light out on the recent OOS Photo Expedition to Raja Ampat. Most people who shoot snooted photos set up on a rubbly bottom to shoot nudibranchs or other small subjects that don’t move around too quickly. It can be a bit frustrating to get everything all lined up!

Misool in Raja Ampat, with its rich reefs and walls doesn’t have many of those types of photo opportunities. So I decided to use the Macro Snoot Light on a couple of short arms off a ball mount on my Nauticam D850 housing and just swim it around on a wall dive. This made for a very compact and easy-to-dive-with macro lighting system that’s pretty versatile.

As the light is a “constant on” light, you can see exactly what your shots will look like. The main difference with using the snoot light over a strobe, is that you are shooting with ambient light. You’ll need darker areas to shoot, with a higher ISO and overall exposure. The light from it doesn’t flash at high speed and amplitude like a strobe to freeze action, so shots will have a softer look to them, and the colors less saturated.

But this can give you some nice, soft lighting and shots with a much different feel, that are really more emotional looking. This contrasts nicely with brightly lit macro shots.

The Kraken Macro Snoot Light comes with a small, round “light limiter” that puts out a very tiny section of it’s 400 lumen light. If you were shooting with high magnification, this might work out well, but it would take holding it off to the side on a small tripod and locking down the setup to shoot it. I quickly decided to use just the light with no limiter and with my Nikon 105VR lens and a +5 diopter to make it easier. The light itself has a small focusing lens on it that casts a larger beam that’s soft and yet limited, sort of a small slightly rectangular beam.

To dive on the wall in some current, I pre-aimed it at some small invertebrates so that when I was at the focus distance of the lens the light was aimed correctly on that same area. Then I could just swim along, find something to shoot and only have to do a small bit of adjusting. I ended up shooting at 1000 ISO at f/20-22 and still could shoot at 1/125th of a sec to freeze the shots. I just adjusted the aperture, let the rest alone, and made slight movements of the light to change my exposure on lighter or darker subjects. I was thus able to shoot quite a few different subjects, unlike other times with a snoot on a strobe that might take 10 mins or so to set up.

I was pleased with the results and got some shots I wouldn’t of gotten otherwise with a strobe. I ended up with darker foreground and backgrounds with the light right on the subject to isolate it from busier backgrounds.

I think the Kraken Macro Snoot Light is a nice small addition to a DSLR travel kit and would also be a nice way for compact camera photographers to use a lightweight solution to get into snoot photography on a budget.

Gone But Not Forgotten

Forgotten Islands/Banda Sea Photo Expedition, November 4-15, 2018

Stories don't have a middle or an end any more.
They usually have a beginning that never stops beginning. 
— Steven Speilberg
After a few great days of diving at Tulamben on Bali, I joined up with the rest of the Optical Ocean Sales guests up in Ambon, Indonesia. The 12 of us joined the Damai 1 the next morning and settled into our comfortable cabins onboard. We were headed for Maumere on Flores Island - 1,000 nautical miles away, clear across the Banda Sea which lies lies between Raja Ampat in the north and Komodo National Park to the south. Over the next ten days, we would do 35 dives at some of the most remote sites anyone can imagine. Islands, walls, sea mounts, volcanos, reefs and muck - we would dive them all.

We did two brief dives in Ambon and were treated with a couple of Rhinopias, nudis and other great life there. That night would be the first of many long passages we’d have, crossings taking anywhere from 9 to 14 hours. This would also be one of the few rough nights at sea, for most of the trip it was beautiful weather with glassy seas and no rain, unusual in the tropics. We did four dives at Nusa Laut and were treated to a huge school of Jacks along its sloping walls on a couple of dives.

The next day was a treat, as we were near Banda Island with lots of site choices. The clear winner was Suanggi Pinnacle, which was a fairly large sea mount, probably left over from a volcano. The north wall is steeper and over two days we’d do two dives there and one on the south wall, which was more sloping. A kaleidoscope of different sized fish made seeing the actual reef almost impossible at times. We had glimpses of shy Hammerhead sharks - as we would on and off thoughout our time in the Banda Sea. While we did see other liveaboards, there was always lots of choices of dive sites and the boats cooperated with each other to ensure a good time was had.

We spent the night quietly at anchor in the harbor at Banda Neira. Banda was the heart of the Dutch East Indies, aka “Spice Islands” dating back to the 1600s. Nutmeg, mace, cinnamon and many other spices remained a heavily guarded crop by the Dutch. Native Indonesians were made to work as slaves and an uprising resulted in hundreds being killed and the establishment of a fort by the Dutch, which we toured, along with a nutmeg plantation.

Review: Nauticam MWL Wet Wide Angle Lens

Nauticam's innovative new MWL-1 is a game-changing wet mount wide angle lens. Designed to be used in front of a housed macro lens, it allows for an approximate 150° field of view with excellent sharpness and quality.

Using a specialized double lens flip holder, you can now switch to three lens lengths; shooting close-up macro with a diopter, shooting standard macro with the 60mm lens or a moderate fish portrait type shots), or a wide angle lens with a 150ยบ field of view.

The lens is compatible with FX and some APS-C DSLRs, Mirrorless, Compact,  MFT, 1" sensor compacts (see lens chart). Nauticam is continuing to test and add more lenses. The MWL-1 allows for focusing from infinity all the way to the front element, so it’s quite good for CF/WA shots. The ability to shoot wide angle and macro on the same dive is now a reality - even for full-frame DSLR systems!

I took one of these new Nauticam MWL-1 lenses for my Nauticam NA-D850 housing rig with me on our recent Optical Ocean Sales Forgotten Islands Photo Expedition to Indonesia and I'm very impressed with the results.

MWL Lens: The lens comes in a zipped and padded soft case and includes the Nauticam bayonet attachment, including male and female parts. The MWL is fairly small with an integrated lens hood. The hood can be rotated as necessary for alignment. As the optics are high-quality glass, the lens isn’t light and weighs 2.6 pounds out of water and about 1.25 pounds underwater. A small flat port for the required camera lens is all that’s needed to add it to your rig. No extensions, zoom gears or other parts are necessary.

This is the real hidden beauty of the MWL - its small size for travel and diving. It can replace a large 9” glass dome port, 90mm extension, zoom gear and large camera lens! This makes traveling with a large FX underwater rig much easier.

Setup: The lens couples with a macro lens, in the case of the Nikon FX cameras - the AF-S 60mm macro lens. The MWL, and a flip mount with a diopter is fairly heavy and is a bit of a challenge to get neutral.  On my NA-D850 (with lighting) I added about 5 pounds of flotation to and it became more reasonable to work with, if still a little negative. There is not a flotation colar yet available for it, so a Stix float belt worked pretty well.

Usage: I had a number of lenses at my disposal for the trip; my favorite Sigma 15mm FE, Nikon 16-35mm, a borrowed Nikon 8-15mm FE, and the new MWL. For macro, I had the standard FX 105mm VR lens and the AF-S 60mm macro to couple with the MWL. I mostly used a SagaDive +10 diopter with the 60mm as I like it’s small size and power.

The MWL handles well in the water, and the coverage is quite wide at about 150° (depending on the camera and lens used with it). It does get a little long and a bit bulky with the added flip holder, floats, diopter etc. But it’s easy to get used to and it certainly is no bulkier than a large domed lens. Having a little longer port and lens meant that I could also move my strobes forward a bit. As it is a small dome lens, sun flare was easily controllable, if existent at all, and sunballs are fairly easy to shoot.

The new Nauticam flip holders designed for it must be used, as the older flip holders aren’t strong enough to handle its weight. They are a bit stiff and I sometimes had to hold the rig against myself to flip the lens up or down.

It also focuses down to its very small dome for CF/WA. It's easy to shoot big animals, or flip over to a macro diopter for tiny subjects. This opens up a great opportunity to tell a story, creating a series of photos with different points of view.

The lens does need to be stopped down to get the best performance. Nauticam recommends f/16 and after some testing, I agree with that parameter. You could cheat it a bit to F/14, but the shots soften quickly with the high resolution D850 below that.

Comparing it to the Nikon 16-35mm, the 16-35mm lens with the S&S focus diopter allows shots to be taken easily to f/11-f/13 range. I actually find the NA-D850 to be well-balanced with a 9” glass dome and extension in the water, with only a small amount of floatation necessary. Split shots also work great with a large dome and the 16-35mm.

I will still pack a fisheye lens such as the Sigma 15mm FE, or Nikon 8-15mm FE along with a small Nauticam 140mm dome port, as I still want that super wide lens in my arsenal.

DX Mode on an FX Camera for Macro: A 46MP image allows for a lot of cropping, and the creamy dynamic range is great. But I’ve struggled a bit with depth of field using the Nikon 105mm VR lens. I’ve had to either approach my subjects from a flat angle, so that they weren’t foreshortened, or stop way down to f/29 (past normal diffraction sharpness settings) to get enough depth of field. I wasn’t always that happy with the resulting sharpness, or lack of depth of field.

So I decided to put the D850 in DX mode and use it that way with the a macro diopter wet lens. This got me back to a very comfortable, and sharp, f/14-f/16 aperture range on the lens with greater depth of field. It’s not just a cropped image, the optics of the cropped sensor allow for more depth of field at the cost of a smaller image size.

While I don’t have a super large 46MP image, I do have a 26MP image with greater depth of field and sharpness. Which I think is a good tradeoff. I like the larger viewfinder on the D850 in DX mode as you can see beyond the image edges for framing.

It’s a nice way to use the MWL lens setup and gives you another gear to shift for macro shots. Obviously you wouldn’t want to shoot the MWL lens in DX cropped mode as you would undo most of the benefit of the wide angle field of view.

Conclusion

The Nauticam MWL wide angle lens is a versatile and compact solution to the vexing problem of housing a mid-range lens without having to carry a large dome port. It shoots quite well, and opens opportunities for mixing your shots up on the go. While it’s not inexpensive at $1850, it uses the relatively inexpensive 60mm macro lens and port that many people already have. Adding up the cost of an expensive mid-range zoom lens, large glass dome port, extension, and gears, it’s a cost-effective and smaller solution that’s travel friendly.

For a high-quality general purpose, mid-range lens solution, it might be something to consider for your underwater rig. See more shots taken with a variety of lenses with the D850 on my Forgotten Islands trip here.
