Sony a7 III Great Value In High Quality 120fps FHD!

Sony a7 III

There is no question the Sony a7 III just announced by Sony is making a splash in the midrange to professional camera markets. We have a $1,998.00 USD Full Frame camera that can shoot 10fps at the full 24MP sensor resolution with probably the best AF tracking system ever shipped on a camera aside from the slightly better Sony a9.  The low light performance of the new a7 III is quite frankly impressive with nearly as clean video to the king of low light the a7s II up until ISO 12,800.

It also has the same high-quality 120fps Full HD mode in both full frame downsampling and APS-C crop modes with continuous reliable AF tracking that performs as good as the a9 system because when it comes to spec comparisons they seem identical.  You will be better off with this camera if you are looking for 120fps full HD than any we have seen before as quality, low noise, focus tracking and dynamic range all come together to create a superb package. → Continue Reading Full Post ←

Chronos 1.4 RAW to DNG Tool Now Available!

Chronos 1.4 RAW

The Chronos 1.4 Team has now posted the first incarnation of the RAW Camera data to DNG File tool to convert the sensor information files to usable Adobe DNG sequences. They also have posted a sample image comparing the before and after characteristics of the image quality if saved on H.264 in camera and then the same scene shot and saved in RAW format which converted to DNG yields a substantial improvement in image quality as we explored in our previous post about this issue here.

The camera is expected to allow direct to DNG format file saving in the future but now you can shoot in the camera RAW format and later convert as an interim solution without sacrificing quality on the H.264 files.  Maybe in the future, the camera will be able to simultaneously save RAW and H.264 files as a proxy feature to be able to easily sample clips in editing before conversion.  We believe the DNG format should be your one-stop solution for this camera if image quality is important for your use case. → Continue Reading Full Post ←

Chronos 1.4 RAW Video Frame Samples!

Chronos 1.4 RAW

We received a set of Adobe DNG image samples from Krontech to check the resolution, dynamic range and grading potential of the camera when using the  RAW recording mode. As of now the utility to convert the raw data is still being tested but we were impressed by the results the camera was able to achieve by offloading the de-bayering process to a more capable converter like the Adobe Camera RAW module.

The Chronos files were already good when properly exposed but did suffer from some aliasing and moire in fine detail while resolution also took a hit by saving in a compressed H.264 format.  Now with the DNG RAW capability, we are glad to see that the camera image quality made an enormous improvement in the resolution, color fidelity, and dynamic range. It really brings out the real potential of the camera for a variety of applications, also creating a cleaner result in the noise department when processed correctly. → Continue Reading Full Post ←

GH5s More Rumored Specs Emerge With 240fps!


The latest info from 43 Rumors stemming from supposed leaks on the GH5s or “Low Light Version of the GH5” suggest a 10.28MP sensor with up to 240fps Full HD recording capability.    There seems to be an out of step rush to deliver this camera compared to previous releases by Panasonic which may or may not end with a product on the specified date of Jan 8th, 2018.

There has been a clear progression of frame rates from Lumix GH cameras from 60p to 96p, 120p and most recently 180fps with the GH5 and G9.  However, if the GH5s ships with 240fps we can safely assume that the spec will now be the bare minimum frame rate for a flagship camera in full HD instead of the 120fps most can shoot in high-quality mode.  The GH5 suffered from quality degradation above 120fps with aliasing and moire taking a toll. If the new camera can deliver 240fps with the same quality as 120fps then it will be a milestone mirrorless camera. → Continue Reading Full Post ←

GH5s Red Ring Gate Rumor Explained by Jon Houldsworth!

Jonathan Houldsworth has posted a video detailing this week’s rumor of the expected Panasonic GH5s camera.  The video includes the detailed 4k footage zoom in that started all of it.  As far as we can tell the footage has not been doctored and this is a new camera with a red ring.  4/3 Rumors is also pushing back the date of the GH5s announcement from December 15th to January 8th 2018 due to a mixup between the press event and the public release.  Enjoy!

GH5s Rumor Video Analyzed & Dispelled! (Updated)

GH5 Rumor Video Analyzed

The video that started the entire speculation craze the past few days from Neumann Films showing a supposed GH5s Panasonic camera with a red colored dial akin to that of the recently announced Lumix G9.  We have downloaded the video and isolated the video frames where the red dial is visible and scaled it for easy showing.

The camera is in our interest because it may offer 4k 120fps in its specs according to the rumors. In our findings, the supposed GH5s camera is nothing more than a plain GH5 camera that is momentarily reddened by a compression artifact set of macroblocks that changes to a red hue after a light change, then reverts back to normal. In our video analysis, you can clearly see the effect. → Continue Reading Full Post ←
