Lumix GH6 will do 120fps 4k & maybe more!

Lumix GH6 Panasonic

Panasonic unveiled in May the GH5 Mark II which is a slight refresh of the venerable m4/3rds GH5 with live streaming, better dynamic range in video, better AF algorithms, and slightly better IS on a very similar body with just a few cosmetic red buttons and rings for refresh purposes.  The slow motion remains at 180fps VFR at 1080p and 60p at 4k on the GH5 II since it is using the same sensor and imaging engine. It is a better overall camera than the original but a mild refresh nonetheless. 

That brings us to the pre-announced GH6 which is an in-development camera that aims to refresh the entire Micro 4/3ds line in Panasonic and aimed at professional video users.  It sports a new sensor, new imaging engine, new body and new technologies yet to be disclosed.  According to rumors, this camera should be able to keep micro 4/3rds alive for another five years delivering an array of video and photo features that will set it apart much like the original GH5 carved a place in camera history. We have also received rumored specs that may or may not pan out regarding frame rates which we find somewhat credible.  → Continue Reading Full Post ←

Canon New Cinema Camera Will do 240fps in 4k!

Canon it seems is thinking 3 steps ahead of everyone else when it comes to pro 8k video.  After being left behind in the adoption of 4k and playing catch up to the format, they seem intent on making their cameras the new 8k default option with specs that seem out of a dreamer’s wish list.  Be warned that these cameras will probably start at $10k USD and go up from there. The low end should be about 10k to $15k for the C300s at the low end, and the high end a $30k price tag for a C700DR.  

The most impressive of the new rumored cameras is the Canon EOS C700DR (DR Stands for Dynamic Range) which will be capable of recording 4k not just at 120fps but a class-leading 240fps with excellent quality. It also hints at a 180fps mode that will have expanded dynamic range if needed.   It is interesting that 1080p as a slow motion mode is not even considered here but these cameras are geared to a specific market and that is digital cinema which needs much more resolution nowadays than what even 2k can deliver, much less 1080p.  → Continue Reading Full Post ←

Canon C70 Slow Motion is finally pushing the envelope!

Canon C70 Slow Motion

We consider the Canon C70 as the real successor to the 5D Mark II which started the ILC  DSLR revolution.  It ticks almost all the boxes for a vast array of users and does so on a somewhat realistic price point. We get a Cinema caliber sensor in S35 format at 4k Cinema and UHD that is capable of producing 16 real stops of dynamic range. The camera actually is using simultaneous dual gain technology to merge the exposure from both settings into an amazingly beautiful progression between light and dark.

The Canon C70 Slow Motion Mode has real 120fps 4k with HDR and full Canon dual pixel AF technology and even can crop to Super 16mm to record 180fps at 1080p and 2k resolution to provide you with that extra oomph which was sorely needed in Canon land. The camera does have some drawbacks but it is so good out of the box that we may have an avalanche of switchers to the format from Sony, Nikon, and Panasonic.

Canon C70 Main Features:

  • Super35 Dual Gain Output (DGO) Sensor
  • 4K 120p, HDR
  • 2K Crop 180p/1080p HDR Capture
  • Canon Log 2, 3, PQ & HLG Recording
  • RF Lens Mount / EF Mount with Adapter
  • DIG!C DV7 Image Processor
  • 16+ Stops of Total Dynamic Range
  • Built-In ND Filters / Auto ISO & Gain
  • Dual Pixel CMOS AF & EOS iTR AF X
  • 1 BNC Timecode / 2 Mini-XLR Audio Inputs
  • Dual SD Card Slots, LUT/Long GOP Support
  • $5,499.00 MSRP Pre-order at Adorama
  • Estimated release date of December 2020.

As you can see the camera is a powerhouse for a vast majority of users. Studios can use it without problem for paid projects as an A or B cam for a C300 Mark III for example or just build an army of C70s to cover events from many angles. The camera performs great in low light with ISO 25600 being the first initial noise bump that may need Noise reduction software in post but below that, a 6400 ISO shoot should be extremely clean.

Canon C70 Slow Motion Component:

  • 120fps 4k and UHD
  • 180fps 1080p/2k Super – 16mm Crop
  • 4k 50/60p
  • Resolutions:
  • 4096 x 2160p up to 119.88/120 fps
    3840 x 2160p up to 119.88/120 fps
    2048 x 1080p up to 179.82/180 fps
    1920 x 1080p up to 179.82/180 fps
  • All with up to 4:2:2 10-Bit capture.

The image quality at 4k 60p and 120p is excellent, we see crisp detail and the codec options are plentiful enough to deliver a good to excellent image in those modes.

However, the 1080p and 2k with a Super 16mm crop loos soft and mushy.  Compression is not that bad but detail is sacrificed from what we have seen. We need to wait for more samples but the ones we have seen make us believe that it looks more like soft 720p upscaled than real 1:1 pixel capture.  4k is immune to this but not 2k and below.

Canon C70 Slow Motion Footage Samples:

We found some samples and we made sure to copy the time stamp so they should start playing at that point.  We find the quality in 2k to be passable but it is not very detailed which makes us think it is not really a 1080p or 2k signal but a soft upscaled one.
