Nikon Z7 and Z6 Mirrorless Have 120fps Slow Motion!

Nikon Z7 and Z6 Mirrorless

The slumbering Nikon has awakened to the mirrorless present and future and has shown their cards in a very strong but not class-leading mirrorless product line.  The Nikon Z7 & Z6 are nearly identical bodies with changes in the sensor and AF. The more expensive and higher resolution Z7 screams pixels with a 45.7MP Full Frame sensor  ISO 64–25600 range which should be a direct replacement for D850 users. The other Z6 is a better low light camera geared more at wedding shooters and videographers at 24.5MP which should produce outstanding low light  ISO 50–204800 with ISO expansion.

There is a lot to like in these cameras like a real 5 axis (5 Stop) IBIS stabilizer on the full frame sensor which also works on adapted lenses and works with Nikkor VR lenses from DSLR cameras to increase the 3 stops to a real 5 stops hybrid stabilization feature. The video modes offer 4k at 24, 25 and 30p which is so 2014 as is the 120fps full HD 1080p slow motion mode.  AF also changes between models at 493 points on the Z7 and 273 on the Z6. → Continue Reading Full Post ←

ASUS ZenFone 5Z Firmware Improves Slow Motion Quality!

ASUS ZenFone 5Z Firmware

The ASUS ZenFone 5Z (ZS620KL) Phone is a new addition to the company line but seems it was a little rushed in the camera department. IT has just started shipping to customers worldwide and there is already a firmware update. The phone is a flagship device with a starting price of $499 which is not bad at all considering it sports some of the best hardware features in Android land. With dual cameras, 6GB of RAM and the latest Snapdragon 845.

The 5Z Phone is a midrange slow motion performer with 120fps and 60fps 1080p recording and the super slow motion mode capping out at 720p 240fps.  The improvements in the new firmware improve the recording quality overall and codec bit-rate of the 240fps 720p mode. Since ASUS does not give out the particulars in the bit-rate department it is hard to say how much better it will be. → Continue Reading Full Post ←

Chronos 1.4 New Firmware Improves h.264 Image Quality!

Chronos 1.4 New Firmware

The Chronos 1.4 team has been hard at work on firmware improvements. The latest pre-released software patch shared with HSC improves the h.264 file quality at the pixel level by using a new demosaic algorithm to better match the real camera output.  We did a few sample tests to see how big an improvement it is and also to maybe ditch the slow and space eating RAW 16bit workflow which is our preferred file saving format as it retains all the sensor information.

The new improvements are already available to the community as a beta in this post. It is very stable it should immediately improve the way you work with the camera. Also, a new roadmap of upcoming firmware releases was shared in the forums which include HDMI monitoring and a complete OS change to Debian Linux from the current Arago distro for the camera which should improve development and speed in implementing features. → Continue Reading Full Post ←

FUJIFILM X-T2 vs X-H1 Slow Motion Quality Comparison by CVP!

The FUJIFILM X-H1 which offers 120fps 1080p slow motion was a worthwhile effort to offer high frame rates that are usable to their video-centric base. It still was not as good as the Sony or Panasonic slow motion options due to aliasing, moire, and noise but with a little post work, it could be used with success in an edited piece.  FUJI then with a firmware update for their stills flagship the X-T2 allowed the camera to now shoot the same 120fps 1080p slow motion which makes sense considering they use the same sensor on both cameras.

The camera site CVP has done a full comparison review here which pits the X-H1 against the X-T2 to see which camera strengths are ahead on each body and if it makes sense for X-T2 owners who are invested in a FUJI lens system to upgrade.  Their findings are interesting and as far as slow motion it is clear that while they use most of the same imaging pipeline; the X-H1 has the edge with less crop, less aliasing, and better artifact suppression when using the 120fps slow motion mode. → Continue Reading Full Post ←

Huawei P20 Pro Slow Motion 960fps 720p Mode!

Huawei P20

Huawei’s P20 Pro is a beautiful phone that merges the sleek design of the Samsung Galaxy series with the Apple front screen notch while not compromising in camera design with a 3 sensor + lens combo that may be the best camera solution on a phone yet. In fact, DPreview has an article on the stills camera performance here. They call it “the most innovative mobile device we have seen in quite some time”  which is a tall order considering how good the competition camera’s like in the Pixel 2 XL, Galaxy S9 and the iPhone X have gotten.

What interests us, however, is the slow-motion mode which allows the phone to shoot a 0.25sec burst of 720p video at 960fps which is slightly above the time recorded by the Galaxy S9 and Sony Xperia XZ series of last year but still below the new Xperia XZ2’s 0.4 seconds at 720p this year.  We were not impressed with the quality of either phone when it came to overall resolution and artifacts so we were skeptical about the Huawei P20 Pro since the start. → Continue Reading Full Post ←

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 ←
