EVA1: Panasonic AU-EVA1! Announcement and latest updates

Not open for further replies.
In mix+crop mode aka 2.2k mix mode which extends framerates up to 240fps, Eva1 seems to have horizontal lines in the shadows and color fringing and black pixels and aliasing on high contrast edges. I posted samples in the Eva1 Facebook group and someone from Panasonic mentioned they are still optimizing HFR modes and and will probably release a new firmware not long after camera release. Unclear if it will fix those specific image issues in crop+mix mode.


Edit: whoops did I say Sony?

Is Sony set to fix Eva1? That's a new one. I've seen FPN from Canon and Panasonic but Sony have been pretty free from that in my experience.
 
The top-over-bottom video in the ProAV. Anyone else think the C200 image produces a more pleasing aesthetic? Not talking about color, that can be graded and shifted etc. But the background bokeh. It's not just detail resolving.

ProAV did not state if this was the exact same DoF used, it looks deeper on the EVA-1. But they were so detailed on everything else, I am trying to figure out why, if the aperture and lenses there truly are consistent, why the out of focus EVA-1 background looks so much more in focus and less "dreamy"?
 
for that test the C200 had a Sigma (prime? zoom? dont know) on it. the EVA1 had the Canon 24-70mm. both have a 24.6mm sensor width. so while not definitive, the simplest answer would be different apertures. the defocus looks identical on the interior tests where the lens was the same.
 
Makes sense. Wonder why he used two different apertures to test AF?

The Canons do produce a sharper image than Sigma.... why I hate tests with any differences in variables other than the camera itself.
 
Didn't realize the base ISO 2500 would not work in 240p mode. Not the end of the world but a bummer because more light sensitivity as a benefit goes hand in hand with higher frame rates unless under controlled light conditions. Oh well. At least 120fps still maintains base iso 2500 which is good.

I want to see more new firmware ISO 2500 footage, that isn't lit to the moon, since the noise problem exists/existed in the lower ranges. Was the youtube footage above shot on the final firmware version?

Base ISO 2500 looks "ballpark" as good (though not equal) to Base ISO 800 on the upper range of brightness... but that lower half of brightness ranges just looks like high ISO.

Who knows. This was the best look at the EVA1 by far, but not exactly ideal. Why did he compare color by only adjusting contrast and saturation rather than showing us each manufacturer's intended look? To his credit, Carl was careful to qualify this as an "unscientific" test and the most valuable thing he did was provide the camera files so we could test some things for outselves.

Yeah this morning in one of the EVA1 facebook groups, another rep said a new firmware update would be available when cameras start shipping that addresses the noise at 240fps. that being said, it's important to keep in mind that at 240fps, base ISO dropped from 2500 to 1250. Carl shot his test at 3200 which without that drop would have been akin to shooting it at 6400.

At the highest frame rates, the sensor suffers from an electronic form of Reciprocity Failure. Anyone else here old enough to remember that term from the film days? Reciprocity Failure is the point at which the reciprocal relationship of exposure time and ISO broke down and were no longer accurate. You could expose of 1/2 the time and double the light level to keep exposure consistent, but push that relationship 10 stops in either direction and it is no longer accurate. This was important in high frame rate as well as timelapse photography. On EVA1, basically the refresh is so fast that the sensitivity is altered in a manner beyond the linear scale of standard ISO ratings. An electronic threshold is crossed, decreasing performance. Because of this, for this mode the Dual Native ISOs had to be lowered by one stop to 400/1250 in order to maintain consistent performance.

I love you for this.

The EVA1 is shipping now with LongGOP codecs in 150/100/50mbps varieties. In early 2018, All-I intraframe codecs will be added in 400/200/100mbps varieties. Recording capabilities will be the same for frame rate/resolution/bit-depth/color-sampling combinations, just additional codec options available for given modes.

There is no option of a LongGOP codec in 400/200 mbps?
 
I just very quickly dipped into the ProAV vid, the AF test, and preferred EVA1 colours. Much better colour separation and skin tones on the EVA1 in that heavy foliage scene, while green cast over the Canon footage. Maybe just settings?

And did anyone notice the bike in the background of the Canon C200 raw shot? Very high noise levels in the red channel after grading.

Both these new cameras look incredible though.

Does this mean that the DR is maintained at 14 stops? Or is one lost in 2.2K? As I seemed to observe a drop in DR a couple of weeks ago (maybe this has changed). Also, this loss in sensitivity seemed to happen at all frame rates in 2.2K mix mode, not just the high frame rates. So what’s the situation when Shooting 24p in 2.2k mix? Is the sensitivity there or not?

Thanks!
 
Any way to get a 2x crop from this camera? It should be one of the few cameras who could offer a nice s16 crop mode.
 
I spent 12 hours with Bill Totolo shooting the EVA1 yesterday.

We didn't have a manual but the camera is pretty straight forward. Here's some quick highlights of what I've learned testing first hand so far-

Number 1 thing- battery life is incredible. 1x battery lasted about 10-hours of typical narrative/commercial style shooting, and we were not trying to power down every chance we got.

Dynamic range is deeply impressive. On par with more expensive cameras.

Camera body is so light it will spoil you when working with other camera systems.

We couldn't get a steady 4K over the HDMI into the Odyssey 7Q+ I suspect our HDMI cable may not have been up to the task, and we didn't have another 2.0 cable to try.

Home Button! What a great addition to the side of the camera, super easy to get a Varicam style menu you can navigate with touch screen LCD. If you don't learn anything else, learn this button.

Menu! Much more intuitive and professional than previous Panasonic cameras in a similar range. Super easy to change camera frequency and frame rates without any reboots.

As expected "Low Light" ISO of 2500 is pretty incredible.

Even though high end SDHC cards are supposed to be cross-compatible with the SDXC format, the EVA1 didn't like any SDHC Lexar cards we used. Angelbird 128GB SDXC cards and Sony SDXC 300MB cards both worked great.

I've got some deeper thoughts on the camera but I'll save those for now. Also, if you don't know there is an "EVA1 Professionals" FB Group, it's the only place I'll be posting some of the images shot with the camera for a bit. Extremely happy with image quality of the EVA1.

I'm not really in the Panasonic camp, but what an incredible asset it is for them to have someone like Mitch being involved with the community on a pretty much daily basis.

RED has something similar going on over on REDuser, and its importance can't be overstated. And it doesn't even have to be about involved technicalities… it's just that someone is there paying f*ing attention.
