How to overcome Q3 going below set Minimum Shutter Speed?

Makes complete sense, since you then just increase exposure in post and add the same noise again. (or worse, depending on software, I suppose?!)

🫠

I did not conclude that.

Also, what made you think I would increase exposure in post? Was it sarcasm I read?

So, you don't understand how exposure works, then?

You want to both limit the iso AND limit the shutter speed, thus effectively FORCE the camera to underexpose when there's not enough light.

Either, you will then increase the exposure in post (which adds noise) or you accept dark, underexposed images..
Increasing exposure in post will have the same effect as just letting the camera increase the iso on its own.

 

If you don't understand that, then that's fine.

Ive only had the Q3 for about 2 weeks and I've already experience this as well. I hope they can figure out a fix.

Never experienced this on the original Q either, and I noticed it right away on the Q3. 

I am pretty sure it works the same on all Leica cameras as on most other manufacturers. There is nothing to fix.

It definitely works the same on the Q3 as on my Nikon and Sony cameras.

I had the Q1 for 6 years. I used it for commercial work, events, portraits, sports, literally everything. It never went below my lowest setting of 125 unless I manually set it. Regardless of the lighting conditions.

You are correct.

The Q DOES have a faulty auto-iso setting, where the Camera will resort to producing blank/black pictures that are horribly under-exposed without warning the user or, like ANY self-respecting manufacturer does, ignore the shutter speed limit in order to produce correctly exposed images.

I cannot, for the love of me, fathom how you could seriously work with such a faulty design.

Did you just scrap thousands of images that were under-exposed?

Or did you, like everyone here suggested, increase the exposure in post?!

Because if you DID do that, then we're back to square one: just leave the max iso at MAX iso and let the camera adjust the exposure correctly.

@mbphotox  What do you do when you need a shutter speed of 1/250 (or faster) for your moving subjects but the camera does 1/30s without warning?

What does Canon do? The shutter speed remains unchanged at 1/250 but aperture value and ISO value start to blink in the viewfinder to warn you that correct exposure is not possible any more.

Maybe I misunderstood your post above. It got not clear to me if you support the way the Q3 works or if you do not support it.

What is the benefit of sticking to 1/250 at an ISO limit vs letting the ISO go up (no ISO limit)? I know the disadvantage (EVF getting too dark to frame).

The camera displays the shutter speed. That should be warning enough. It is good custom to always check metered values before taking an image.

Canon R5 behaves the same as Q3 (and all other cameras).

Just as SrMi pointed out, any "normal" camera will reduce the chosen minimum shutter speed instead of just wasting your shot completely.

What you want is a fixed shutter speed, bc you are shooting moving subjects. That's fine.

Thank you, I wrote my post out of my head but you are fully right. Of course: What I spontaneously always do is to set the shutter speed manually. Its so much in my workflow and I am seldom in fully Auto and I remebered wrongly. Thank you for clarifying.

With Q3 I do exactly the same: I set shutter speed manually in lower light and I let flow the ISO.

To prevent your Leica Q3 from lowering the shutter speed below your set minimum when the max ISO is reached, you can switch to manual mode. In manual mode, you can control both the shutter speed and the ISO settings yourself. This way, the camera won't automatically adjust the shutter speed to lower than what you want. Another option is to use aperture priority mode and set a higher maximum ISO limit, so the camera has more room to adjust ISO instead of lowering the shutter speed. Unfortunately, Leica doesn't currently offer an option to stop the camera from reducing shutter speed once the max ISO is reached in auto settings.

This is exactly how I have mine setup, wide open with Auto ISO limited to 25000, with a minimum shutter speed limit of 1/250s. In most of my shooting conditions, I have manually set my shutter speed to 1/500s and let the camera control the ISO. Living the aperture to my control, giving me the artistic freedom. This is all subjective of course as we all shoot different things and will require different exposure requirements. I have found at least that 25000 ISO is the perfect limit as it produces natural noise and retains details. But like what most have pointed out, noise does not come from high ISO, but usually comes from having to pull details from a shadow.

Hi all, I've read this forum but maybe I'm miss understanding some replies, sorry english is not my main language too.

Coming from a Fujifilm, where I do have a minimum shutter speed option together with a min and max ISO setting, I've been 1h with a Q3 in my hand in a store and didn't understand that concept on a Leica. Also went to the PDF manual, dowloaded from the site and on page 195 I got even more confused. It's like the concept is max shutter speed (instead of min).

I should give an example of what I use frequently on my Xpro3:

I do setup a profile with min shutter speed = 1/250 for street photography, with min ISO = 160 and max ISO = 6400. I then go on using the aperture ring on the lens, usually between f/4 and f/8 ... I'm shooting at f/4, shutter auto goes to 1/1000, ISO go auto on 160, there is enough light so the camera prioritises low ISO, makes sense ... I then push the aperture to f/8, the shutter speed automatically goes down but locks on 1/250 (because I've set it up before) and thats when the ISO kicks up until I do get the right auto exposure.

So the sequence for me on Fujifilm is Aperture (manual) > Shutter (min value 1/250) > ISO AUTO until 6400.

This is very important for my street workflow and I would love to clarify my doubts here before thinking about the Q3.

 

UPDATE: I've read the whole post and got the conclusion that there is no solution for this besides use manual settings (at least in part) but just to make sure my unperfect english is not betraying me 

Help appreciated

If you go outside these parameters the camera will adjust to give you a usable image. The best workflow is to set your optimal shutter speed and aperture manually and let auto ISO do the rest.

In the bright sunny conditions that we have on some recent days I have been using an adjustable 1-5 stop ND filter by K&F to keep the exposure within the bounds that I prefer: ISO 100, f/1.7 - f/8, 17100 - 1/1000 sec. This is readily attached, adjusted and removed.
