GoPro goes anamorphic with Letus AnamorphX adapter

GoPro cameras are widely used in sports and are possibly the more popular action cameras on the market.

They are also possibly the cameras of choice to mount on a multirotor to shoot aerial video. A wide range of accessories, namely gimbals and video-out cables are available to mount and use a GoPro on a quadcopter or multirotor.

The typical, very wide field of view of the GoPro also makes these cameras useful to pilot in FPV, although many suggest to instead use a second, simpler board camera for the flying itself,  because possibly more things can potentially go wrong with the GoPro with respect to a simple camera with less functions. However the GoPro often remains the camera of choice to take the footage for video production.

The GoPro wide angle lens gives GoPro images a distinct fish eye touch that is very easy to spot, as in the image below.

Lens protector now available for wide angle Mobius camera, to be used for FPV

As it happens, care to details and sometimes the use of some dedicated, although simple and inexpensive devices can go a long way in protecting your expensive equipment. One piece of delicate equipment used in RC models, and in particular for FPV, are indeed video cameras, with their exposed lens.

We have been discussing the setup of the Mobius camera for FPV in a previous post. Since then, a nice new model with wide angle lens came out:

This is even better than the original version as for FPV it is great to have an as wide field of view as possible.

The wide angle lens is however somewhat bulky and protrudes prominently from the camera body. In the event of a collision, the lens will make for a great shock absorber for your multirotor, especially if the camera if mounted on the front of the aircraft, as it usually happens.  But of course you see the point here: chances of damaging the precious optical element are significant.

There comes to the rescue a great, lightweight, little custom piece of equipment designed by Bo Lorenzen (check out his Blog at FPVGuy.com) as a shock absorber / lens saver to protect the lens of the wide angle Mobius camera.

I tried it and it is a perfect fit. Once in place the piece will grip strongly to the camera. A little pressure on the two little “wings” will release grip and allow a smooth removal.

The mobius wide angle lens protector is described here and can be ordered from Shapeways. It is made with a 3D printer from the original Bo Lorenzen design.

Secom’s surveillance drone – An advanced flying security camera

As reported in this Nikkeibp story, Japanese firm Secom has released an innovative security camera, able to get close to the target and shoot pictures and videos to be used for information and evidence in security investigations. It is actually a medium sized  (80cm diameter) quadcopter with an unusual shape that offers way more flexibility and maneuverability than a fixed camera, even with PTZ control.  This one will track the target anywhere even in a huge area.

When a non authorized person or vehicle enters the secured area, the quadcopter will get close and gather evidence about the intrusion by taking pictures and video. The drone can take pictures of a car license plate for example.
