The Panasonic Lumix BGH1 is a strange camera if you are used to DSLR or Mirrorless camera body styles. It is tiny and full of connections with no screen unless you provide one via a computer that is tethered or an HDMI field monitor. It uses the same dual ISO sensor found on the Panasonic Lumix GH5s which is a very good low light camera in a Micro 4/3ds package. The BGH1 has a better internal recording set of options than the GH5s but it is more intended as a tethered studio solution with the addition of Genlock synch and SDI out.
The camera also has VFR or a Variable frame rate mode which is identical to the Lumix GH5s as it records from 1fps to 240fps in Full HD 1080p and delivers pretty good performance up to 200fps then lowers the quality along with providing a small added crop to the image at 225fps and 240fps. It is still not as sharp as regular 1080p video and the codec is saved at a lower bit rate but having 240fps as an option is great.→ Continue Reading Full Post ←
The new v2.02 firmware update for the Panasonic EVA1 includes improved bit rates at a variety of frame rates like: 2k- 422-Intra Frame Recording 200M/100M Max 120fps (equivalent to 400Mbps) Which may improve slow-motion quality considerably by allowing more data to be saved instead of scrapped.
For digital recorder owners, there is a lot to be excited about as the camera will now output RAW data at: 5.7K/30p Full sensor, 4K/60p Crop , 2K/240p Sensor Crop. Since the 240fps mode saved internally exhibited very severe aliasing, moire and line skipping; the fact that RAW is now a possibility should bring the camera’s capabilities up a notch and deliver excellent slow-motion quality. We hope to have some samples of the RAW recording on the EVA1 in a future update.→ Continue Reading Full Post ←
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 ←
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 ←
As suspected in a previous article from HSC the Panasonic G9 bitrate for VFR or high frame rate mode is much lower than on the GH5. The Manual has been released for the G9 showing this lower spec. It is of note that the codec used on both cameras is very efficient which lends itself to good quality even at 20mbps. However, for those that want to prioritize fine detail and the utmost sharpness, the GH5 will, in the end, be the better option for slow motion.
There is also the upcoming announcement rumor of the GH5s Lumix camera now with leaked images here with 240fps at full HD using a completely new sensor which may be able to improve of the GH5 slow-motion quality which in our analysis was lacking when using 150fps and 180fps on the regular GH5. Aliasing and moire were evident in footage which is not present in the 120fps mode. Considering the GH5s might be recycling the same image processing engine but with a new sensor, we may still see some artifacts.→ 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 ←
