Panasonic has released the specs of a new smaller version of their Varicam professional video camera with an S35mm sensor. The Varicam LT is the low cost version of the Varicam 35 which has higher end specs at a significantly higher price. The Varicam 35 has a 4k mode that allows up to 120fps at full 4k resolution while the Varicam LT has less power at a maximum of 4k 60fps.
The LT is mostly identical after that 4k downgrade in the rest of it’s capabilities with dual native ISO of 800 ISO and 5000 ISO for extremely clean image quality at those native ISOs. The Sensor itself is built for those opportunities that need higher sensitivity but also allow to shoot at reduced sensitivity for bright conditions. This is great news for the use of the high frame rate feature. The inclusion of EF mount and PL signify the seriousness of the product for an installed base of videographers and film makers with a growing arsenal of Canon and PL glass instead of Panasonic only lenses. They also state that EF lens compatibility will need to be tested and they will not support it directly.→ Continue Reading Full Post ←
In our last post we looked at the HSC768 high speed camera project that had great performance and ergonomics including a jog wheel design and machined case. We asked the creator of the camera David Kronstein, who runs the Youtube channel Tesla500 from Vancouver Canada, a few questions regarding the future of the project and he kindly responded with some great insight. We may have a third competitor in the HD high speed camera market to go head to head with the edgertronic camera and the yet to be released fps1000 project.
While the camera is still in the lab stages, it shows a usable design with professional looking performance and a pretty lengthy buffer. There is a touch screen interface based on a stripped down Linux OS installation and DDR3 high speed DRAM 16GB worth that can do quite a good set of frames.→ Continue Reading Full Post ←
tesla500 is a Youtube and Patreon video channel by Electronics Engineer David Kronstein that has a lot of videos of engineering projects and troubleshooting / fixing stuff. Some videos are based on a homebrew camera project that gained our attention. The camera is a high speed monochrome at the moment with HSC768 name which is based on the data rate of the image sensor, in this case 768Mpix/s, or about 960MB/s . The camera project started in 2014 as a way to get a high speed camera for the lab without paying the hefty premium.
SIGMA has released a compelling video showing their new process for ceramic lens filters being compared to other brands in a metallic ball drop test. The ball weighs 49 grams or 1.7 oz and it is dropped from a height of four feet.
According to SIGMA, their strengthening ceramic process is 10x or 1000% stronger than previous strengthening methods which are included in the video as the competition to compare them.→ Continue Reading Full Post ←
The Ono U1 Beast smartphone by U1 Labshas yet to see the light of day as a shipping product. There have been several setbacks to the project but they seem to still keep the flame alive by having the hardware finished and polishing the software constantly to get to a ship ready state.
The latest info pushes for a February release of a slow motion video sample at the spec of 480fps. This will be a real video and not an interpolated sample like the one released before which used the Android camera to deliver slow motion video based on standard frame rate footage. Now the talk in the forums is when will backers and early buyers get the phone if at all. The handset was supposed to be in the hands of backers in late 2015 especially taking in mind the holidays as a Christmas present. That did not materialize as expected due to software delays. However the company honored early backers with refunds for the entire amount. These early backers will still get the phone with no out of money cost. This would be a great thing for backers but this put stresses on the actual company making the necessary revenue unless they have investors footing the bill.→ Continue Reading Full Post ←
Regardless of what the GoPro and Ambarella marriage can provide in tandem hardware it is clear the company wants to branch out of the fledgling sales of GoPro which have tanked in recent quarters and the stock price from a high near a $100 USD is now trading at a mere $12 which is half the IPO price. By branching out it seems they want their chips in many more imaging devices and be less affected by the GoPro product cycle.
The announced H2 and H12 chips are able to provide beefy 4k specs at high frame rates for mobile devices at a mere 2 Watts of power. As to 1080p frame rates it will remain to be seen how this powerful new chip can handle that in a camera design and how it is implemented to squeeze that performance. 120fps at 4k from the H2 in theory should be able to yield 480fps at 1080p just counting the Pixel processing. This however can be limited by the rest of the components like imaging sensor.→ Continue Reading Full Post ←
