Lensrentals Breaks Open the EOS R5, Finds Exceptional Weather Sealing

Roger Cicala and the crew at Lensrentals finally got the chance to do a proper teardown of the Canon EOS R5, and what they found is an exceptionally well-sealed camera that's packed full of the latest tech. That's both a huge pro and, if you're thinking in terms of heat dissipation, a potential con.

Sony Unveils the a7S III: 16-bit RAW Video, New Menus, and New AF System

The wait is over: after many months of rumors, speculation, and leaks, Sony has officially unveiled the Sony a7S III. The video-focused full-frame camera still uses a 12MP sensor, but it can capture 4K at up to 120p, features a thicker body design with hybrid card slots, and debuts an all-new menu system.

Shooting High-Res Thermal Photos of Iceland to Show Nature at Work

A computer vision engineer by day and photographer by night, I never take the path most traveled, especially when it comes to imaging technology. Thermal cameras are one of the most interesting types of cameras, and while they are widely used in industrial, scientific, and military applications, they are largely untouched and unknown to the general public.

How to Capture Heat on Camera Without Expensive Optics

Standard schlieren imaging techniques use a large mirror to be able to visualize heat or pressure differences in air. The problem with these techniques is that they require large precision telescope mirrors that are very expensive. My lab is fortunate to have a 13-inch diameter telescope mirror; but what happens when I need to photograph a larger subject?

See Airflow on Camera in This Awesome Harvard Demonstration of Schlieren Optics

Schlieren flow visualization and photography is one of those things that is just too cool. Using an optical trick, it allows a camera to capture, "small changes in the index of refraction in air." In other words, it can see anything that affects airflow: heat, sound waves, or just plain old air currents themselves.

And the video above, uploaded at the beginning of this year by the Harvard Natural Sciences Lecture Demonstrations YouTube channel, is one of the most fascinating demonstrations of Schlieren optics we've ever seen.

Seek Thermal Camera Gives Your iOS and Android Devices Thermal Vision for Cheap

Earlier this year, we told you about the FLIR ONE, an iPhone case with a built-in thermal camera that made 'predator vision' available to all.

But if the FLIR ONE is just a bit too pricy for your blood, there's a new player in the thermal camera game you might want to take a look at. It's called the Seek thermal camera, and while it's not as impressive as the FLIR ONE, neither is its price.

Nikon Patent Solves Camera Overheating by Integrating Removable Heat Storage

As DSLRs become more and more capable video capture machines, the problem of overheating becomes a more pressing one. With RAW video in particular, where the amount of data being captured is staggering, the sensor needs to be protected if you expect to keep using the camera for any extended amount of time.

Cinema cameras, like Canon's 1D C, have attacked this issue in the past by arranging the internals in such a way as to provide better cooling. But a couple of new Nikon patents take a different approach.

$150 Open-Source Attachment Turns the iPhone into a Thermal Imaging Camera

Modder Andy Rawson needed an easy way to find air leaks in his 100-year-old house in order to improve its energy efficiency. Not wanting to spend thousands of dollars on a thermal imaging camera, he decided to go the DIY route. He built a box containing a 64-zone temperature sensor, and managed to connect the device to his iPhone via the dock. By overlaying the temperature data onto the iPhone's camera display, the $150 attachment instantly turns the iPhone into a cheap thermal imaging camera.
