There is an aura over the Panasonic GH5s that has not been seen in a m43 camera possibly ever. It is mainly due to the outstanding low light quality in 4k 24, 30p and 60p that beats full frame cameras like the Canon 5D Mark IV and competes head to head until ISO 25,600 with the king of low light the Sony a7s Mark II. But as always, our focus is on the high frame rates which the camera also does quite good on.
The 4k 60fps quality is very close to the 30p quality which means excellent and you can shoot at 60p at night without worrying about noise. The 240fps mode which is a first for a Lumix camera in full HD means that the camera aims to compete with Sony RX series cameras that have stacked sensors. We believe the quality to be acceptable but not good enough to be broadcast quality as stair stepping jaggies are all over the frame with the occasional moire pattern on fine detail that can break a shot.→ Continue Reading Full Post ←
In the case of the RED EPIC-W with Gemini S35 sensor, it is the first time RED has used a dual Native ISO sensor like the ones seen on the Panasonic EVA1 and GH5s which have two different native sensitivities to deliver extremely clean footage with the widest dynamic range. Witha claimed 16.5 stops of dynamic range in standard mode & a gain of approximately two stops of light, from 800 to 3200 ISO without increasing the image noise. DPs of all kinds will savor these advances to shoot in dark situations knowing the output will be dependable.→ Continue Reading Full Post ←
After several camera announcements where slow motion was a main feature instead of an afterthought, things have been calming down until the next wave which will break closer to NAB 2018 from April 7th to 12th in Las Vegas. There will probably be quite a few announcements in the professional space which is mainly where things heat up when it comes to higher quality resolution at higher frame rates.
We expect Sony to steal the show with probably the a7s Mark III which by any measure will probably retain the low light king title for the foreseeable future. If the a7 III released recently is any indication then a lower megapixel sensor anywhere between 12-16MP Full Frame with the same technology in a stacked sensor will give us a camera so capable that room for improvement will be mainly on the ergonomics, interface and higher frame rates going forward.→ Continue Reading Full Post ←
Canon at CES 2018 was showing three CMOS sensor products that can be used in a variety of devices like DSLRs, Mirrorless, Surveillance, Manufacturing and Scientific experimentation. These new parts feature massive improvements in resolution, class-leading low light ability and a Global Shutter in one instance.
While none of the sensors could be named a really slow motion capable part, the 5 Megapixel 2/3″ sensor can scan the full chip at 120fps which may mean higher frame rates if using windowed resolution. The small size of the sensor also means it will need a lot of light to deliver a noise-free image. This sensor also sports a global shutter design which is perfect for high-speed applications.→ Continue Reading Full Post ←
So the rumors proved to be accurate on the GH5s and now we have a low light version of the GH5 that can shoot cleanly up to ISO 12,800 with up to 100k ISO and by then a much noisier picture. It is claimed by Panasonic that there was a 1.5 stop improvement in noise performance. Judging by the initial video samples it is clear that the new 10.28MP sensor along with dual native ISO circuitry for each photosite “one at ISO 400” and “one at ISO 2400” make a huge performance leap if low light is desired in a m43 camera.
All is not rosy in Lumix land however as the camera now lacks IBIS or In Built Image Stabilization on the sensor which was a main selling point of both the GH5 and the G9. Panasonic claims that it was a decision made to cater to filmmakers that need no wobble or vibrations in a shot that can be produced when the stabilizer fails. But why not just add an On-Off switch? 1080p 240fps is also included in the camera but as initial samples show it reduces quality substantially.→ Continue Reading Full Post ←
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 ←
