DJI releases Mavic Pro Platinum with better battery life and quieter flight

01 Sep

Like everybody else today, DJI took advantage of IFA in Berlin to announce a few new products. In addition to an ‘Obsidian’ version of the Phantom 4 Pro and a new shooting mode for the DJI Spark, DJI revealed the Mavic Pro Platinum: a longer-lasting, quieter version of the popular foldable DJI Mavic Pro.

In DJI’s own words, the DJI Mavic Pro Platinum “takes all of the advanced features of the Mavic Pro which revolutionized personal flight and builds on them.” The drone is targeted at travelers, amateur photographers and outdoor sports enthusiasts who want a little bit more performance than the original Mavic can offer.

To that end, the new Platinum version improves the battery by 11% for a total per-charge flight time of 30 minutes. It also decreases flying noise by a whopping 60% (4 Decibels), making it a little easier to remain inconspicuous while capturing aerial footage. Plus it looks a bit ‘fancier’ than the original too:

The new Surface Pro: new processors, boosted battery life and more

24 May

Microsoft’s Surface Pro (they’ve dropped the numbering scheme) looks impressive. In an interview with The Verge, Microsoft’s head of Surface, Panos Panay, claims there are about 800 new custom parts in the Surface Pro.

Battery life is up from 9 to 13.5 hours, it’s got the latest Kaby Lake processors, there are promised sleep/wake improvements (an issue that plagued many Surface Pro 4 users), and the device just looks and feels nicer with more rounded edges as well as a barely visible vent.

The Core i5 now joins the m3 in being fanless (the high-end i7 still has a fan). The new hinge allows the Surface Pro to lie almost completely flat at 165 degrees, which Microsoft calls Studio Mode (after the Surface Studio). This’ll make it easier to use with the Surface Dial.

The Surface Pen gets a sizable update as well: it now has 4096 levels of pressure sensitivity and tilt detection (only with the Surface Pro) for better shading and inking accuracy. Perhaps even more important is that it’s more responsive because of a reduction in minimum activation force. Though this time around, it’s a separate purchase.

There’s still no USB-C, and only one USB port (this accessory will help photographers import SD cards to an external drive without a hub, utilizing the Surface’s micro SD port). A new LTE option should be great for those one the go, though a release date for that feature hasn’t been announced.

The new Surface Pro is available for pre-order today starting at $ 799, with the Type Cover coming in at $ 129 and Surface Pen coming in at $ 99. Shipping starts June 15th.

Honor 8 Pro combines big screen with dual-cam and large battery

06 Apr

Huawei’s sub-brand Honor has today released its latest flagship – the Honor 8 Pro, which plays on a very similar level as the main brand’s Mate 9 and P10 high-end models. The 8 Pro features the same Kirin 960 chipset as the Huawei handsets and combines it with a generous 6GB of RAM and 64GB of built-in storage that can be expanded via a microSD-slot. Despite a large 4,000 mAh battery the device is very slim and the front is covered by a 5.7″ Quad-HD display. 

With a dual 12MP-camera setup the camera specification is on paper identical to the standard Honor 8 but the new Kirin chipset’s more powerful Image Signal Processor should slightly improve image quality compared to its slightly older cousin. As on all Huawei dual-cam a monochrome and a RGB sensor are combined to optimize image detail, noise levels and dynamic range as well as produce a simulated shallow depth-of-field effect. Both lenses come with F2.2 apertures and the camera is capable of recording 4K video. There is no optical image stabilization, though. The front camera uses an 8MP module with F2.0 aperture. 

The Honor 8 Pro has, at least at this point, been officially announced for European markets only and will cost you £475/590 in the UK which makes it an interesting alternative for those who want high-end looks and specs at an affordable price point. It will go up for pre-order today on the Honor vMall store and will be available in regular stores from April 20.

Samsung investigation blames battery for Galaxy Note 7 fires

17 Jan

Reuters reports that an internal Samsung investigation has concluded the Galaxy Note 7’s fires and explosions were not caused by faults in hardware or software, but by the devices’ batteries. This information has been provided by ‘a person familiar with the matter’ ahead of an official Samsung report that is expected to be released on January 23. The company is also expected to detail measures for the prevention of similar problems on the upcoming Galaxy S8 and other future Samsung mobile devices. 

Samsung initially started recalling the Note 7 in September last year, offering other Samsung phones as loaners until a ‘replacement’ model arrived. Unfortunately, some of the latter too caught on fire until Samsung decided to pull the plug on the Note 7 entirely, stopping all production and marketing of the device and recalling a total of 2.5 million units.

Reportedly, Samsung wasn’t initially able to locate the source of the problem, despite assigning hundreds of engineers to the task. However, eventually the fires could be replicated in testing, without finding any fault with hardware or software. Considering Samsung was using several battery suppliers for the Note 7 it seems unlikely that batteries were the sole problem in the scenario. So, we are hoping to be provided with some more detail once the official report is released.

Gionee M2017 comes with 2x optical zoom and 7,000 mAh battery

28 Dec

Gionee is a relatively new name in the smartphone world but the Chinese brand has already established itself in Asian markets and is growing quickly in the Western hemisphere as well. With a price tag of approximately $ 1,000, its latest model, the M2017, places itself firmly at the luxury end of the mobile device spectrum; but looking at the specifications, that seems justified.

The M2017’s headline feature is its battery. The engineers have combined two 3500mAh units to create a massive 7000mAh battery that rivals those on some tablets. Gionee claims the device offers  32 hours of talk time or 26 hours video playback on a full charge. Quick Charge 3.0 is supported as well.

The camera specs sound very interesting, too, although Gionee has not provided too much detail. For now we know that the device features a dual-cam with a 12 and a 13MP sensor. This combination allows for 2x optical zoom, like on the iPhone 7 Plus, or a 8x digital zoom. The front-facing camera comes with an 8MP resolution. 

The rest of the specification reflect the luxury price point as well. Images can be viewed and composed on a 5.7-inch dual curved QHD AMOLED display. In terms of memory, there are 6GB of RAM and 128GB of storage. Unfortunately though there is no microSD-card slot, and for some strange reason, Gionee decided to use the mid-range Snapdragon 653 chipset to power the M2017.

The device is made from premium materials, weighs in at 238 grams and, despite the massive battery, is 10.78mm thin. There is no information yet on international availability, but we’d certainly like to have closer look at that dual-camera.

Add Functionality and Battery Life to Your Sony A7 with the MOZA Cage

05 Dec

MOZA sent me their recently released MOZA Cage for review, and while I’m slowly and inevitably getting into more filmmaking with my Sony a7R Mk2, I’m still a photographer first. I thought to myself, “How can I review this cage as a photographer.” After taking delivery, however, I found it quite easy! There are a few unique things you can do with this cage that make it perfect for certain types of photography, not just as a tool for filmmakers.

MOZA Cage Handheld Camera Gimbal Stabilizer

If you’ve never heard of the term Cage used in conjunction with cameras, in very basic terms a cage is just that. It’s a cage that you screw your camera into, and it provides you with multiple handle options, cable routing options, attachment options (think LED panel lights / microphones, etc.). Cages can range from very basic and a couple of hundred dollars, up to fully featured monsters that will see you shelling out more than a grand (USD).

But this one, the MOZA Cage is a mid-priced cage with many features of much higher end products. What stood out to me after I unboxed the cage was the build quality. Everything is really well made and works well, and after using the product for a few weeks on multiple shoots, it has given me no problems.

Still photography uses

When shooting video, it’s great to have a cage to help you hold your rig more steady. It’s helpful to attach a small shotgun mic or LED panel if you’re a run and gun interview shooter, or someone shooting an event, etc. But, that doesn’t really apply to us so much here on dPS, as we’re all about the still photos.

What appealed to me in the stills department is that the MOZA Cage has a sweet wooden handle grip included. And inside that grip is a 4800MaH battery that is used to power your camera! By way of comparison, the included NP-FW50 batteries in my Sony A7 or a6300 are 1020mAh. So, we’re talking about a unit that will power your camera for a lot longer than usual! (I won’t mention the Sony battery performance, except to say that I’d like more please, more batteries!)

Longer battery life

So what does having more battery power do? It gives us the ability to shoot for longer. Obviously shooting film is the first thought, but I used the cage for time-lapse as well as some regular photography and it worked great. The wooden handle on the MOZA rotates so you can hold the camera down low to the ground by the top handle, while you have your screen tilted up to show you what you’re shooting.

The next little added bonus is that the MOZA Cage includes a shutter release in the handle, as well as a video stop/start. That shutter release worked really well for shooting from within the cage at weird angles and doing it with no contorted weird ergonomic photographer’s stance! (You know the ones haha)

Benefits

The cage does have limited use for photographers. But if you’re thinking of trying your hand at shooting some video of your kids, or maybe doing behind the scenes on your next epic production, this cage could really increase your production value. It will give you many more options from a camera handling perspective, as well as those benefits listed for alternate photography uses. The MOZA Cage is $ 499 which, for what you get, is a great price.

If you’re still shaking your head and muttering “Cage, what’s he talkin’ ’bout…cage!” Here’s a quick overview and a look at how you might set up your camera in a cage, be it this one or any other style cage.

Summary

In summary, I don’t really have anything negative to say about the MOZA Cage! From a photography/video convergence point of view, it’s a great mid-level tool that will work very well for you, from a pure photographic perspective. For alternate uses like long events, time-lapse and simply awkward shots down low (I found it particularly handy for these!) it works very well. The build quality, price and customer service were all very good (I did a secret squirrel customer service call with a question… yes, a little sneaky, but we need to know these things!)

Find out more or purchase the cage on Amazon.

The iBlazr Case comes with 40 LEDs and a built-in battery pack

24 Nov

Ukrainian company Concepter, which brought us the iBlazr smart flash in 2013, has launched a new Kickstarter campaign to fund production and distribution of its latest product, the iBlazr Case. The iBlazr Case combines 40 dual-tone LEDs for better flash photography with a 2,500 mAh battery pack and is compatible with the iPhone 6, 6S, 6 Plus, 6S Plus, 7, and 7 Plus models.

The ’40 high-power LEDs’ on the rear of the case are triggered by the phone’s built-in flash via a light sensor, which means the case works with virtually any iPhone camera app. According to its makers it provides 5 times the light output of the built-in LED flash or approximately 300 lux at 1 meter subject distance. The beam angle is 180 degrees and the built-in battery, which can also be used to charge the iPhone, is good for 1500 flash exposures. When the case is used as a flash light it provides more than 2.5 hours of constant illumination.

The LEDs can also be used to display customizable notifications for incoming calls, texts or other events, when the case is paired to the iPhone via a Bluetooth connection. The Shotlight companion app allows for adjustment of the flash color and brightness and is a fully-fledged camera app in its own right. 

The iBlazr Case is made of ABS plastic and coated with a rubber material. The built-in battery is charged via USB Type-C port. You can now reserve a unit by pledging $ 55 or more on the project’s Kickstarter page. Shipping in envisaged for April 2017.

New supercapacitor technology could bring an end to our battery charging woes

24 Nov
 
Image: University of Central Florida

Technological advances have made it possible to do amazing things like order a pizza from your smart watch, but there’s one problem holding much of consumer tech back: battery life. Despite the computing leaps we’ve made forward, batteries are still a major limitation for pretty much all mobile devices and a lot of photographic equipment. However, a team of scientists at the University of Central Florida’s NanoScience Technology Center may have taken a step toward ending our collective nightmare. 

The research team has developed a process for creating flexible supercapacitors that can store more energy and be charged faster than current battery technology. The concept also allows for recharging more than 30,000 times without degradation.

“If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” said team member Nitin Choudhary. 

Unlike batteries, which use chemical reactions, supercapacitors store electricity statically on the surface of a material which means they can be charged quicker. Previous research projects used graphene for this purpose, but with limited success. The team at UCF has instead been experimenting with newly discovered two-dimensional metal materials that are only a few atoms thick. The newly developed supercapacitors consist of millions of highly-conductive nanowires that are wrapped with those materials. As a result, electrons can pass quickly from the core to the shell and high energy and power densities are produced.

“There have been problems in the way people incorporate these two-dimensional materials into the existing systems – that’s been a bottleneck in the field. We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials,” said principal investigator Yeonwoong “Eric” Jung.

At this stage the technology is only a proof of concept and not ready for commercialization. However, the team is in the process of patenting the method and, if developed further, could power the mobile devices, compact cameras and electric vehicles of the future.
