Exposure and Iso safe with Leica Sl

Hello Forum Member

I am new to Leica Sl and have a short Question, I use my camera mainly in Manuell mode with auto iso function and  and alternative lenses where i choose the aperture on the lens. Is it possible to save the exposure time and iso pemanently by pressing a button in m mode/auto iso? Or can i only save this for one exposure with pressing the shutter button softly? In my daily work i often have to take mutiple picture with slightly different viewing axis but with the same settings. Easy to do that with sony´s and canon´s, possible hopefully with Leica too? And i don´t want to dial in exposure compensation, too slow for me in my daily work

Regards

I could be wrong but this sounds like you're asking if you can set the ISO manually as well and have the exact same exposure and gain value for all images taken? If that is your question then yes you can do this, you simply need to set the ISO to gain value you want. But I suspect you already know that.

 

Perhaps what you mean is can you still use floating ISO but lock it in for the next picture, perhaps like exposure lock?

you are right. I mean iso lock, but for multiple shots not just for one.

So assuming you don't want to just set the ISO gain manually it looks like there isn't a solution. The exposure lock method only seems to work in P, A or T modes.

bad to hear, but thanks for the infos

iso lock works  in single shot modus  .... just keep the shutter half pressed while reframing.... not working in rapid fire mode though

So as not to add to the confusion, auto ISO is not the same as floating ISO, which has to do with retaining exposure when using a zoom lens.

If you're looking to fix the ISO for multiple shots, just don't use auto ISO for those multiple shots.

 

I don't see the advantage of auto ISO if you don't want it to potentially change for different shots to equalize exposure.

 

Presumably if you're changing viewing axis slightly and you have fixed aperture and shutter speeds while wanting the same exposure in each shot, the ISO won't change much between them anyway. If it does, then you know that having it fixed would have produced different exposures.

 

You could just keep auto ISO on and use the exposure compensation to ensure it's equal between shots, though again in this scenario you may end up with different exposures.

 

I'm left not understanding the point.

 

1- you have fixed aperture and shutter speeds and want the same exposure for multiple shots with different angles and potentially different light

-- changing ISO may be necessary if lighting is different to equalize the exposure

 

2- you have fixed aperture and shutter speeds and DO NOT want the same exposure for multiple shots with different angles and potentially different light

-- fixing the ISO allows for this and negates any need for auto ISO

 

3- you have fixed aperture and shutter speeds and want the same exposure for multiple shots with different angles and the lighting doesn't change at all between shots

-- auto ISO has no impact because the lighting is fixed

Aha, I didn't know that (I only use two lenses, both manual primes).

I see the advantages of Auto iso, especially with spot metring in difficult lighting situation. It´s fast and responsive to work with. Sure i can fix iso after metring in the camera menu. But that´s to slow for my way of working. But i am fine. At least  it works in single shot mode and in highest speed shot  mode, keeping the shutter slightly pressed while reframing. But why does it not in the other shot modes( at least on my camera) ?
