If you have a set of led lights (or other battery powered device) that you want to turn on and off from a distance, here's a simple idea using an inexpensive set of Wireless Remote Control 12V DC Relays. To keep things fairly universal I decided to make an 'inline' cable that has a male and female D-Tap connection to work with my V-Mount batteries. (This way I don't need to modify any of my accessories). But while i'm using this with my v-mount batteries, you can actually use any 12V-14V battery and any cable connector to fit the connector on your device.
These specific mini wireless remote DC relays can handle up to 10A sustained which is the same max rating most V-Mount batteries are spec'd for. Which basically means if you can power your accessory from a D-tap, these relays should work fine. My setup here is simple, and it's merely just cutting the battery current, so this hack won't let you dim or change color temp, but it's universal enough to be used for powering anything on or off including motors, LCD screens, Wireless Video Transmitters, etc.
Speed and versatility are the calling cards of Sony’s latest, the Cyber-shot DSC-RX10 IV Digital Camera. Using an updated 20.1MP 1" Exmor RS BSI CMOS sensor and BIONZ X processor, shooters can enjoy 24 fps continuous shooting, as well as UHD 4K and High Frame Rate HD video. Further boosting speed is the Fast Hybrid AF with 315 phase-detect points that can lock on in just 0.03 of a second. Also, operation is intuitive, with the implementation of a touchscreen LCD alongside the OLED EVF. And, of course, it stars a 24-600mm equivalent 25x Zeiss Vario-Sonnar T* lens that covers a vast range of subject matter. Read more >>
I like the look of slow motion with the GH5, so I wanted to try shooting an entire real estate demo in 50% speed. For this I used the 4K / 48fps VFR setting (conformed to 24p) on the Panasonic GH5.
Now because of the 48fps setting, I needed to set my shutter speed to around 1/100th to reduce too much motion blur. Finally when working with an F/4 Lens (Panasonic 7-14mm), this also cuts down on the amount of incoming light, so I needed to work with a minimum of ISO 1600.
To control noise, I shot the entire video in 4K and exported to 1080. By downscaling you can mask noise. Also I shot in CinelikeD and exposed to the right (slightly over exposed), which means bringing the exposure down in post and that helps to clean up any noise in the shadows.
So, I did a quick test with my new wide angle lens. While there are certainly better ultra wide angle lenses out there for MFT cameras, the Venus Optics Laowa 7.5mm MFT Lens is a great start if you don't already have one. At under $500 dollars, with an F/2.0 aperture, and the ability to accept threaded filters, there's a lot of value. Otherwise I'm also a big fan of the 7-14mm lens (seen here).
Although it's more than twice the price of the SLRMagic 8mm, I find this lens is far better in every way, and worth saving up for. With it's tiny size and weight, it's a perfect lens to use on the new Pansonic GH5 when flying a single handed gimbal.
While the Laowa 7.5mm lens performs ok at F/2.0 which will help you in dim lighting, you'll achieve better results as you begin to stop down. My video example was shot outdoors on a bright day and this allowed me to stop down past F/8. And by shooting 60p, I was able to increase my shutter to 1/125th and shoot without an ND Filter. Just in case you're wondering I was experimenting with the GH5 CinelikeD Profile and then added color in FCPX.
What camera geek doesn't enjoy a fun novelty item? These little Fake Lens Table Drink Coasters protect the finish of your furniture, but stack together to replicate a Canon lens. Available in 3 different colors. Could be a fun gift idea for photographers.
This seemingly innocuous replica of an 85mm lens is composed of five coasters held together by magnets. The coasters can be easily split apart for use, and them brought back together to rebuild the disguise. Silicone pads on the top and bottom of each piece help absorb moisture and keep your drink from sliding.

Most people have heard about Gen Energy V-Mount Batteries earlier this year at NAB or the Cinegear Expo touting their 'Shock Proof (drop proof)' design, but here's a quick video talking about other clever features you'll find in these V-Mount batteries.
Outside of feeling confident you won't break your battery throwing it around in your gear bag, I like the Gen Energy's ability to reset the protection out in the field (without placing it back on a charger), and how you're able to leave the Battery Meter LED Lights on. This can be handy if you have it working on an LED Light and you need to glance at the power from a distance.
The little features found in Gen Energy batteries definitely give a sense that this company has an attention to detail and are working hard to put out a high quality v-mount battery. When comparing the price + capacity versus other popular brands, I would say it's pretty much comparable. It's neither cheap nor expensive. But if you're specifically looking for a robust battery with exceptional battery management built in, I see no reason not to consider the Gen Energy v-mounts -
