Panasonic G7 - Extended ISO option?

I was taking some low light photos using my Panasonic G7 camera and found that the ISO value of the photos seemed to be stick on ISO 100 causing very slow shutter speeds. When looking at my camera settings I found the 'extended ISO' had been turned on. When I turned it off and tried to take low light photos the ISO then gave me higher settings.

I couldn't find much information about this setting for a Panasonic G7 camera so I'm hoping that someone can tell me what this setting is for.

Extended ISO enables ISO 100 (and perhaps ISO 25600?). Normally, the lower the ISO, the better the image quality. With G7, this is true at ISO 200 and higher. Anything lower than ISO 200 does not really provide better image quality. However, there is still an option to use ISO 100 if it is needed for some reason. This is called extended ISO.

When you are in other modes than full automatic, pressing the up key from the 4-way controller (ISO button), one of the two dials will choose ISO and the other will choose the max ISO. Max ISO will be used if you select AUTO ISO (or intellect ISO or whatever it is called). If you choose ISO 100, the camera will use it no matter what.

Thanks pannumon.

From what I understand when using Extended ISO the exposure is locked at 100 ISO and it's up to me to change the ISO settings to a value greater than 100.
I'm not certain what the different between Auto ISO and intellect ISO as it seems either way that camera will  be automatically choosing the best ISO setting.

I got caught out when taking a few low light photos. I should have paid attention to what the camera setting was showing in the view finder. Also checking one or two photos afterwards. But lucky the camera shake photos were not important to me.

Does these ISO settings also effect the video recording?

From what I read, you probably want to avoid the extended ISO, you may not like it.

I like images from 200-1600 iSO with this body.

The title for this option seems misleading as I first thought it would extend my ISO to higher values than what the camera normal goes up to.

I have now turned this option off.

No. If you are under Auto ISO or iISO, the camera is still free to adjust ISO by itself upto the ISO ceiling that has been set.

I guess you were actually using manual ISO mode. After enable Extended ISO in REC Menu, you might have set ISO to 100. Once a particular ISO value been used, we are entering manual ISO mode.

and it's up to me to change the ISO settings to a value greater than 100.

Yes, it is what manual ISO works.

I'm not certain what the different between Auto ISO and intellect ISO as it seems either way that camera will be automatically choosing the best ISO setting.

Extract from the pdf manual of G7

iISO will not support S and M shooting mode.

Although I shoot with A most of the time, TBH I really can't find the beauty of iISO, so on conservative basis I stick to Auto ISO on my every Panny camera.

Some limitations for Video shooting:

1) In Creative Motion Picture mode (not use under full auto video mode by using the red REC button), "AUTO/200~6400" will be available.

2) For Video (might include both of full auto mode and Creative Motion Pict mode?), UPPER ISO LIMIT is not supported.

Wish the above could help.

Useful information.
In my case I just turned off Extended ISO and the iso automatically set its self to the best value.
