Sony Xperia XZ2 Slow Motion Samples!

Sony Xperia XZ2 Slow Motion Samples

Sony made a headline splash with the Xperia XZ2 last week but samples of the slow motion or HDR were not widely available to really see what the phone could do.  Even today they are few and far between but we were able to find some to make a pretty good assessment of the quality offered in video mode.

We were quite impressed to find a resolution gain that it is quantifiable in 1080p 960fps Full HD mode slow motion that is greater than previously thought. It is still not true 1080p quality but it is slightly higher from 720p which in turn makes this XZ2 Phone the best 960fps phone out there for quality. The Galaxy S9 is close behind but with a severe aliasing increase by reducing the data captured. → Continue Reading Full Post ←

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 ←

Sony Xperia XZ2 1080p 960fps Spec!

Sony Xperia XZ2

The new Sony Xperia XZ2 from Sony is their flagship phone for early 2018. It has a lot going for it like 4k HDR movie mode which is a first for a phone and from what we can see it really makes a difference in dynamic range and color on the footage. It also has the latest Snapdragon 845 SoC for increased performance with the battery savings to boot.

What we are interested however is the slow motion high frame rate capabilities which after the Galaxy S9 with 960fps HD 720p announcement, Sony needed to respond accordingly.  Well, Sony has done so and they now claim 1080p 960fps slow-motion video on their XZ2 phone which is a one up on the Galaxy with more resolution.  However, it is not all that rosy as companies seem to equate a frame size with video quality which in many cases is not even close to spec. → 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 Slow Motion Quality is Inferior to GH5!

GH5s Slow Motion

As expected based on early comments of the slow motion mode on the GH5s, the camera has pronounced aliasing “seen in this video by Max Yuryev” and softness the higher the frame rate goes. Even at 120p it is less detailed than the standard GH5.  It may be a function of supersampling in the higher megapixel  20MP GH5 vs the 10.2MP GH5s which is creating the new artifacts.

While the GH5s can shoot up to 192fps without cropping the sensor, anything above that up to 240fps it has a slight sensor crop which further decreases quality.  While the VFR mode on the camera is better than most cameras in the price range that attempt the feat, it is of note that the quality instead of increasing or remaining the same as the sister model takes a hit which may kill it as an option for slow motion needs.  We still believe the standard GH5 is the best Lumix option even when compared to the G9 in VFR mode. → Continue Reading Full Post ←
