Hands-on Review – Nissin Di700A Speedlight and Wireless Trigger Kit

09 Aug

Following the big bang that introduced capable and affordable digital cameras, the digital photography universe has been expanding at an astounding rate. So much amazing imagery is being produced, and equipment manufacturers are working tirelessly to develop, and improve upon, the products you use to create those images.

Despite the tendency of some photographers to not even consider third party brands, that market exists and is flourishing. It seems that there are more players in it than ever before, and the competition is stiff.

Photography accessories

The market for third party photography equipment and accessories is bustling.

If you are considering adding a speedlight to your arsenal of gadgets, it’s definitely worth having a look at third party brands. Don’t make the mistake of assuming that a product is inferior because it’s not the same brand as your camera.

Although the industry dominators (Nikon and Canon) have a large array of speedlights to choose from, you just might find that you have to pay for features which you will never use, or their products may not have the features you need.

One company that has gained some ground, making a name for themselves in the third party sector, is Japan-based Nissin. They are a dedicated photographic lighting company who just released a new flash system for Nikon and Canon (Sony version coming in September) and one just showed up on my doorstep.

I shoot Nikon so they sent me the dedicated Nikon system but don’t worry, the Canon and Sony versions are similar, so this review is still worth reading even if you’re not a Nikon shooter.

First of all, this is exciting for us Nikon shooters. Unlike Canon, Nikon doesn’t have any flashes with radio triggers built-in, only optical. Why? Good question. Get it together Nikon.

First Impressions

Excavating the Nissin Di700A out of its packaging – yes, that’s the alphabet soup name they gave this unit – it was instantly apparent that it is meant to rival the SB-900/910, at least in size and weight.

Side by side comparison of the Nissin Di700A and the Nikon SB-900

The Nissin is in many ways comparable to the Nikon SB-900.

A quick inspection of the unit shows it to be sleek, simple, and solid. The plastic seems heavy-duty and I suspect it would survive some abuse. The locking head swivels and swings into the same positions as its Nikon counterpart – 7-degrees down, 90-degrees up and 180-degrees left and right (as every flash should).

On the back, below the matte-finish LED screen, is a dial with a Select button in the middle, a flash test button, and the power button. They went for the minimalist approach which I applaud. It has a small rubber cover on each side; one with a socket for a battery pack hiding behind it, and the other with a PC cable and auxiliary sync inputs.

The metal hot shoe mount is a welcome sight but the circular threaded disc for tightening the flash onto the hot shoe seems a bit archaic. A slide-out diffuser and reflector panel are also familiar features.

You may have noticed that earlier I called this a camera system. The kit they sent me comes with a radio trigger called the Air 1 Commander. The hot-shoe-mount Air 1 matches the flash in most respects, but has an extra Mode button. It automatically locks into place when slid onto the hot shoe, and has a button which is held in to release it. Personally, I would have preferred the same button on the speedlight instead of the threaded disc.

Firing it up

I popped in four AA batteries, hit the power button, and a kaleidoscope of colorful lights sprung to life on the rear panel. However, the flash was effectively frozen and would not work at all. Come to find out, the Eneloop XX rechargeable batteries that I prefer to use for all of my speedlights do not work in this unit. I swapped them out for the regular Eneloops which work fine. The only difference that I’m aware of is the XX are 2,500 mAh compared to the regular’s 2,000 mAh (any electrical engineers out there please chime in).

Following the thread of simplicity that Nissin has going, I just tightened that baby down onto my hot shoe and it did what it is supposed to do, fired away in TTL metering mode.

I instantly fell in love with the rear display. Various bright, vivid colors, clearly visible in any lighting conditions, indicate the six different menu settings:

  1. A (automatic)
  2. TTL (through the lens metering)
  3. M (manual)
  4. SD (slave digital)
  5. SF (slave film)
  6. And the wireless setting identified by a little radio tower symbol

A few things I liked immediately were: a quick press of the power switch locks all functions of the flash so you don’t inadvertently change settings, the tactile feel of the buttons and wheel are soft but feel very sturdy, and changing modes and adjusting exposure compensation is quick and easy.

Another issue I encountered was that the zooming flash head feature didn’t work. It zooms all the way out when deploying the small diffusion panel but did not respond when changing the zoom on any of my lenses as the manual says it should, nor does it respond to the manual zoom control feature of the Air 1. We’ll assume I got sent a defective unit. To play devil’s advocate, this can happen to any brand so I’m not going to throw them under the bus just yet.

The controls on the Di700a are intuitive and very easy to adjust to get the exposure just how you want it.

The controls on the Di700A are intuitive and make it quick and easy to adjust and get the exposure just how you want it.

A detail that could prove handy is the standalone battery magazine. Spares can be purchased which can be pre-loaded for easy swapping. This can save you time and prevents fumbling around for batteries in the heat of the moment.

Perusing the instruction manual divulged that the flash has an overheating circuit which supposedly shuts it down for 15 minutes, to recover after firing 20 to 30 times (presumably at full power). This is a significant detail as 15 minutes might as well be an eternity for professional shooters. I immediately had flashbacks of the SB-900 which would overheat and shutdown often, and at the most inopportune times.

The system supports all of the nifty features found on the camera body: high-speed sync (FP for Nikon and HSS for Canon) to 1/8,000th of a second, red-eye reduction, slow and rear -curtain shutter, and on-camera exposure compensation which is added onto the unit’s own exposure compensation, covering two stops in both directions.

The Nissin Di700A not only has a built-in wireless receiver, but can also be optically triggered by the camera’s built-in flash. This is cool because you can mix and match flashes that have optical receivers. The Di700A and the Air 1 can be purchased separately. The Air 1 wireless commander claims a 100 foot effective range. Although this may seem generous, and plenty for most applications, the Cactus transmitters I use boast three times the range but do not support TTL metering, so it’s a trade off.

Using the Air 1 with the Di700A proved undependable. My first attempt at about 50 feet, with the flash behind a motorcycle for backlighting, was met with intermittent results. The signal seemed weak, and I had to move around to get the flash to finally fire.

Testing the Nissin Di700a and Air 1 commander.

I had mixed results using the Air 1 to trigger the Di700A. The system struggled having the motorcycle between the flash and transmitter at about 50 feet.

The Air 1 can also support three groups of flashes, on eight separate channels, with exposure compensation for each group in half stop increments.

I would certainly recommend the kit to beginning through intermediate shooters, but despite Nissin’s efforts to offer some pro-level features, it falls a little short to meet the demanding needs of working photographers.

All in all, for a sub $ 300 kit, that is sleek and easy to use, versatile, and capable of wireless TTL shooting, the Nissin kit is definitely a strong contender.

Soylent 3.0: 100K Sq Ft Warehouse Could Feed 4 Million People

09 Aug

[ By WebUrbanist in Conceptual & Futuristic & Technology. ]

Photobioreactor PBR 4000 G IGV Biotech

The first generation of Soylent is a powdered food substitute for all your nutritional needs, the second will be a premixed beverage boasting the addition of algae, but the ultimate target is fully-grown, ultra-efficient food equivalent. An eco-friendly paradigm shift, this would allow vast amounts of healthy calories to be created in very small spaces, a single small factory space supplying enough for to sustain the entire city of Los Angeles.

soylent in a bottle

In just a few years, Soylent went from an experimental substance to the household name in food replacement, but its creator’s endgame is far more ambitious than the current niche product might suggest. Soylent 1.0 remains relatively cost-intensive to produce and expensive to consume – it provides simplicity, but only for those who can afford it. Soylent 2.0 will begin targeting broader markets and introduce algae-grown components, but a future version (3.0, perhaps) could truly revolutionize food production and distribution.

soylent powder

Imagine using just water, sunlight, air and a single algae superorganism to generate the complex nutrients (including carbohydrates, proteins and lipids) needed to sustain life, with applications in rich and poor countries (or in space). Then consider having this substance available on tap, piped right into your home like water or power. Alternatively, you might buy your own household bioreactor, churning out Soylent 3.0 directly in your kitchen on demand. Rob Rhinehart’s vision takes various forms, but it comes down to the same thing: an alternative to conventional food and potential solution to unsustainable agricultural practices, available to all those who wish to take part.

Not everyone will want to subsist partially (let alone entirely) on Soylent, now or ever, but that is also not the point – it can always be used in conjunction with other meals by those so inclined or deployed to places otherwise without sufficient food for subsistence. Meanwhile, for the next round (from Motherboard), “The algae [called AlgaWise] in Soylent 2.0 is grown by the biotech company Solazyme, in a facility owned by the Archer Daniels Midland, the food processing giant. The oil is then pressed out much like olive oil. It’s amazingly efficient. Entire tanks can be filled in days.” Solazyme calls the stuff AlgaWise.”

More from Rhinehart on current and next steps: “In the interest of building a sustainable business to fund our research we’ve been focused primarily on product improvements and new products, like the launch today, but I’ve also worked on setting up infrastructure including lab building and recruiting and drawn up a roadmap for reaching the goal of cell synthesis, starting with protein. This process has two modules: one strain engineering to develop and optimize the organism that produces, the other bioreactor engineering to make an ideal growth environment for the strain(s).”

Opinion – Erez Marom: Whatever it Doesn’t Take

08 Aug

One of the common ways landscape photographers seek to set themselves apart from others is to shoot from hard-to-reach locations. The notion that a ‘good’ photographer is one that pushes his or her physical boundaries – hikes farther, climbs higher, endures pain – all to get a unique shot. In this opinion piece, photographer Erez Marom calls this idea into question. Read more

Absolut Brilliance: Vodka Shipping Containers to Workspaces

08 Aug

[ By Steph in Architecture & Offices & Commercial. ]

absolut containers 1

Four bright blue shipping containers formerly used to transport Absolut vodka have become ‘Creative Space,’ a versatile series of workspaces at the company’s headquarters in Åhus, Sweden.  Recent architectural grads Astrid Skog and Charlotte Stuveback stacked the crates and transformed them into working environments supporting a wide range of creative processes. The structure was used for Absolut’s ‘Hackathon,’ a three-day event exploring ways to creatively repurpose materials like glass vodka bottles and otherwise reduce the company’s environmental footprint.

The shipping container workspaces consist of four distinct areas: the bar, the distillery, the workshop and the bottlery. The bar offers a place to relax, drink coffee, read magazines and talk to fellow designers. The distillery is a brainstorming space, and the bottlery encourages experimentation with ideas in early phases. Finally, the workshop is where these ideas are made into real products and concepts.  One of the coolest projects that came out of Hackathon is a DIY sound system set into Absolut bottles and hung from the ceiling.

The spaces are full of their own impressive hacks, including a bunch of suspended vodka bottle lights and reuse of cardboard bottle sleeves as horizontal organizers within wall shelves. There are slide-out work surfaces with sawhorse-style legs and rolling crates full of tools tucked under tables. Now that the event is over, Absolut plans to ship the Creative Space crates to a new location so they can be used for innovation again.

Weekly Photography Challenge – Feet

08 Aug

Feet are an important part of our human body. They take us where we want to go. They hold us upright. They can be all different sizes and styles, decorated or plain, even covered in fur (think pets). But they are often overlooked in photographs or even cropped off.
