The Panasonic GF2 doesn't have IBIS.

here I speak about GH5

You might have to enable "shoot without a lens" in the menu. It's the same on all cameras basically.

I can't find it in my GH5 @Mattias Burling

Hi guys,

I am looking to turn on IBIS for my manual lens (no connection between body and lens)

I would like to use sensor stabilization but it does not work... only works with my native 25mm 1.7 panasonic lens... is this normal? any settings to change??

Hello there,

I am having a question about color profile with the GH5, for the low light situation.

Imagine you are in a lowlight situation (in the street), shooting skin tones, would you use CINE-D or Hybrid Log Gamma?

Thank you.

It looks good to my eyes.

Can't see any purple besides the fringing on edges.

I can see some ghosting on the walls by the way

Hi there,

I have done some V-LOG shots, C4k 10bit 24fps 150mbps LonGop, using GHALEX lut, I can see an excess amount of green and purple tones in the black areas, is this normal?

thx.

Looks pretty normal for Log footage to me.  ?‍♂️

No issues with the sensor so?

great to hear it isn't from the body, I thought those grains were from the body

"Chromatic aberration, also known as “color fringing” or “purple fringing”, is a common optical problem that occurs when a lens is either unable to bring all wavelengths of color to the same focal plane, and/or when wavelengths of color are focused at different positions in the focal plane"

Its common on lenses when the aperture is open all the way. 

yep, I have opened the lens 1.7 so that's why it has a very magenta look @thebrothersthre3

what do you think about the video? does the quality look good for you? I mean as all the others GH5? no particular issues with sensor?

If you ever end up with some of that in a shot you want to use, you can suppress it pretty well by using a soft mask around the problem area, key the purple and desaturate it.  Best to just avoid it if possible ?or use a better lens if you have one when shooting high contrast.  

yes, I use cine lenses 17mm 0.95, samyang 16mm T2.0 etc. , I don't have this kind of thing with them

Just now, Towd said:

Yeah, the purple stuff around the trees when the focus is changing looks distracting.

ya, it's just very quick test footage I did, used auto focus

purple fringing and pulsing focus.

what do you mean by "purple fringing"? lens aberration? @Towd

V-log-L on GH5 and Gh5s is known to exhibit severe noise in shadows even at base iso. Even when properly exposed and with the highest bitrate. It’s one of the main reasons I’m holding my breath for the S1.

ya, I know right, that's why I'm seeing a lot of noise in dark areas, I thought it was an issue from my body, but when changing to cine-d, I don't see it anymore.

it's also because of my very cheap lens lol

@@yan_berthemy_photography Did you just buy this GH5?

yep

What lens are you using and what's the f stop at and what was the ISO in that video/screenshots? Just looks like a grey, poorly lit scene with noise.

@Video Hummus 25mm 1.7 from Panasonic, a lot of lens aberration. very cheap lens

I tried with my CINE lens, looks so much better, I don't have aberration

shot 1.7, ISO400

the red dot is the zoom tool, OKAY. That is what I wanted to know.

 

The artifacts look like noise to me. Could it be that v log is disabling noise reduction and thats why you notice it? Hard to tell with just the screenshots shown.

video here:

@mnewxcv

V-LOG everything -5

could be because there is not enough of light, as you can see in my others shots with v-log, there is no such issue.

Yes talking about the red dot

 @thebrothersthre3 this is not from the sensor, from my zooming software, to zoom 300% in the footage.

what about pixels in my footage? any ghosting issues?

attached screenshots with cine-v profile, less artifacts as you can see.

Its not normal but I don't know why its happening 

@thebrothersthre3 what do you speak about, the red dot?

this is the zoom feature in final cut pro

8 minutes ago, mnewxcv said:

also it may be obvious to some, but I have no idea what camera you have. Please specify. To me the red dots looks like hot pixels.

@mnewxcv

I use GH5.

this red dot? this is final cut pro x zoom framing, this is not from the footage...

15 minutes ago, thebrothersthre3 said:

Those red dots show up in your footage? Seems like a sensor defect not an issue of pushing the footage too far. 

I don't have red dots in others profiles..., this is artifacting from V-LOG, I was just asking if you found this normal?

here are some others shots I made in the middle of the day, let me know what you think:

do you speak about those pink dots in the trees? this is lens aberration and the purple bud in the trees

7 minutes ago, mnewxcv said:

re you referring to the red dots? I don't see what the picture after that shows. Do the dots move as the video plays? Can you take another video and see if they are still present?

no, does not seems to move with those dots, I'll send you a video

Just now, thebrothersthre3 said:

Post in the GHAlex thread, Sage who made the LUT responds directly there

@thebrothersthre3

having another question, what about refreshing pixels on the GH5?

do you think this is an issue from the sensor itself or from my exposure?

I'm getting magenta pixels...

1 minute ago, thebrothersthre3 said:

10 or 8 bit? Not sure if you are supposed to expose normally with the GHAlex lut. 

this is 10bit 4k

I would be more worried about the TSA agent. I had one break a gimbal trying to figure out what it was. Another agent cut a hole in my sweatpants pocket; I put my phone in it later, only to have it fall out on concrete lol. 

@Snowbro

Really? broke your gimbal? did they refund you? this is not serious from them at all... I would not call this "TSA Agent" I would call this shitty people

Hello there,

I am getting artifacts issues in black areas when it comes to using V-LOG, I did expose my grey card correctly, around 45-50IRE

screenshots below, some screenshots V-LOG version graded and zoomed at 300%

Shot 4k at 10bit 150mbps

as you can see, when grading with GHALEX DAYLIGHT, I'm getting a lot of artifacts while I exposed my shot correctly, do you think these are hot pixels or underexposure (shot in sunset)

Thanks, kind regards.

waiting for an answer.

After taking numerous cameras from numerous manufacturers through numerous different airports, I'm going to venture my anecdotal experience of the only risk to your gear going through the scanner being someone "accidentally" picking your bag up at the other end if you yourself don't get through the metal detector fast enough.

 

so, metal detector could affect product you mean but not x-ray?

I am going to Island on May 2019 from ORLY airport in France,

I was wondering if putting my GH5 in the X-ray detector could affect its system, especially the 3 axis stabilization system and the GH5 sensor...

do you think this can create hot pixels or damage video recording system?

Thank you.

Hi there,

I was wondering which quality settings do you guys use for commercial stuff such as weddings, music videos, etc.

I found 4k very hard to edit with some leggings issues, etc. what do you recommend to shoot with? 4k 10bit/8bit 60fps or FHD 10bit?

will 4K look like FHD if downscaled to FHD?

Thanks
