Panasonic G80 Live View in manual mode not working as expected

[Vlad-Roman]

Hello everyone.

Sorry if this is a stupid question, but I can't seem to find the answer online.

I recently bought a G80, and when I'm shooting in Manual Mode, Constant Preview is OFF, a high fstop, a fast shutter speed, a low ISO, when I'm half pressing the shutter button to focus and lock the exposure, after the image is focused and exposure is locked I expect to see a dark or black image. But what I see is that same bright image on the viewfinder/screen. And only after I fully press the shutter button and take the image, I see that dark image.

When I have the same settings on my FZ1000 for example and I'm half pressing the shutter button, I get a live view of the image that I would get ( a dark/black image ) if I would fully press the shutter button.

Can anyone help me reproduce the same behaviour on the G80 please?

I also tried to set Constant Preview ON, and this way, when changing parameters in Manual Mode, I get a live view of the image that I would get without half pressing the shutter button. But I'm interested to achieve the behaviour that I described previously.

Thank you!

Hello everyone.

Sorry if this is a stupid question, but I can't seem to find the answer online.

I recently bought a G80, and when I'm shooting in Manual Mode,

Under M mode, the usual live view mode (lightness of the frame changed according to the parameters changes) which is defaulted to P/S/A/iA is no longer available. It is a standard for all Panny M43 (IIRC it should be the same for Panny compacts including FZs as well?).

As per above, under M, Preview can be setup as the default viewing mode to perform as the LV. It is controlled by Constant Preview. Many misunderstandings that CP is the viewing mode itself. It is not but just a control to determine how Preview!

Preview will perform similar to the LV under P/S/A/iA showing the lightness changing according to changes in parameters correspondingly more accurately without restriction.

Please note that Preview comes in Shutter Speed Effect and Aperture Effect modes.

Since LV mode is not available on M, if CP = OFF, you will have an auto grain evf/LCD only which will be bright enough (auto adjusted according to the environment) to operate the camera without any relationship to parameters used.

Constant Preview is OFF,

As said, you are under auto grain Evf/LCD viewing mode. It will not show how the parameters would affect the output.

TBH, it is good to use when slow shutter speed because Preview would also simulate the shutter speed effect. If I shall shoot with, e.g. 1", the Preview image would refresh only every 1" instead of the usual 30fps or 60fps. You can imagine the difficulty to operate under such serious view lagging.

To address this I have set CP=OFF & M in a C mode, use it when I shall enter 0.5" or slower shutter speed zone (for low lighting M shooting). Otherwise, CP will always ON as a default.

a high fstop, a fast shutter speed, a low ISO, when I'm half pressing the shutter button to focus and lock the exposure, after the image is focused and exposure is locked I expect to see a dark or black image. But what I see is that same bright image on the viewfinder/screen. And only after I fully press the shutter button and take the image, I see that dark image.

When I have the same settings on my FZ1000 for example and I'm half pressing the shutter button, I get a live view of the image that I would get ( a dark/black image ) if I would fully press the shutter button.

Not sure on this since I no longer use Panny compacts after moving to M43 many years ago. But as far as I read, FZ100 should do very similar to its M43 siblings.

Can anyone help me reproduce the same behaviour on the G80 please?

If you would shoot in slow shutter speed often, set up a C mode as me. Having CP=ON and when switching to M, you can have Preview immediately. Use the C mode when entering slow shutter speed zone.

I also tried to set Constant Preview ON, and this way, when changing parameters in Manual Mode, I get a live view of the image that I would get without half pressing the shutter button.

As said, Preview is the defaulted view under M when CP= ON, no extra key been needed.

But I'm interested to achieve the behaviour that I described previously.

Sorry can't help because I have no interest on the said optical vf alike operation. LV for precise exposure setting is the main reason I gave up on using DSLR.

Thank you!

Sorry for taking a while to respond back and thank you for taking the time to explain!

This is a very good solution to what I wanted to achieve, thanks!
