How to overcome Q3 going below set Minimum Shutter Speed?

The best way to achieve this, probably, is to use exposure compensation assigning it to the thumbwheel. Setting the dial to -1 or -2 is usually enough to prevent the camera from overriding the SS.

Thanks for your feedback.

I will test by creating a User Profile for -1 is a good way to check if the camera will respect the Minimum SS all the time when shooting this way. A downside is constantly underexposing may not be good idea where ETTR is required.

Just a quick summary of all the ideas so far:

1. Different User Profiles

2. EC -1 or -2

3. Completely manual

Anything else?

As I understand you want to achieve the following:

- set min shutter speed and max ISO

- once max ISO is reached, do not lower shutter speed in order to underexpose to preserve highlights.

- there is no need to underexpose to preserve highlights if the max ISO setting has not be reached.

That’s true, but I also want to keep noise reasonable by not going beyond 3200-6400, since I have a slow computer. 

Q3 took out a big chunk of savings so upgrading computer is not an option right now so I can’t let ISO float to stratosphere 🤣

But your solution will not keep the noise reasonable!
The only way to keep the noise from going too high is to allow shutter speed to change below the min value.

My understanding is as long as I compose my image in a way that I don’t need to lift the shadows in post, then I don’t need keep lowering SS once max Auto ISO is reached, right? 
 

I just thought of another approach, use highlight metering but EC up instead of EC down.

If you can set exposure at a fixed minimum shutter limit speed that does not require lifting in the post, then you can set the same when the minimum shutter speed is not fixed once the ISO limit is reached (by applying negative EC).

Yes that’s true. I think this conclusion has been reached after exploring eveythign in this thread. As other posters have said, both are not elegant because they require manual intervention at some point.
 

Having an algorithm or toggle that stops the camera from going lower than “minimum SS” is the ultimate but sadly it doesn’t seem it’s the norm for camera manufacturers. 
 

Edit: but apparently Canon is smart enough to offer this option according to another post I read in a related thread! Now there is hope other camera manufacturers will “catch up” with Canon in future 😅

I own the Q2 instead and...If it's night time and I absolutely don't want the shutter speed to go any slower and I know the camera won't be hitting ISO100 (which is 99.99% of the case even if it's wide open), I just set the desire shutter speed manually. Not the most elegant solution but there are plenty of photographer appreciate the camera slowing the shutter speed upon reaching the ISO ceiling.

Olympus/OM does as well, but you have to dig for it! (In the flash menu if memory serves)

I think we are still not used to realising that sensors built in the past 5-10 years work quite well at amazingly high ISO settings, and that almost any noise can be neutralized by using raw files and cliking a button in pp software.

Before this thread, I had no idea why anyone would set an Auto-ISO limit lower than the max ISO. Now, I understand that it can be used to specify maximum allowable noise. To work as intended, the shutter speed must decrease once the max ISO value is reached; otherwise, the noise will increase.

This is an issue with the M digitals as well. When shooting in aperture priority the camera choses high iso and high shutter speeds some times, when in reality a better image quality would be to lower both. The solution is to go manual.

Qfan, I just wanted to chime in to say I feel your pain and recognize a kindred spirit. 

I can see a case for sacrificing the auto ISO threshold so that your automatic shutter speed limits are never transgressed; it is a matter of your priorities. Just saying to switch SS to manual ignores that a second later, lighting conditions could be good enough to increase your shutter speed to an even safer speed, if stopping motion is your goal. This is why I don’t accept that advice uncritically. 

In Aperture Priority there are two legs of the exposure triangle with which to compromise so why not make it the photographer’s choice?

I often find that the Q3 makes strange exposure decisions. On the other hand, my car, a Mazda MX5, often recommends changing to a higher gear than I would normally select. When I take the advice, it never results in the engine stalling!

Seriously, though, there are times when I seriously contemplate going fully manual with the Q3 — except for focussing: the arrival of auto focussing improved my success rate immensely!

Thanks for voicing your support. With so many responses echoing the same pain, it's quite clear to me that Leica should further improve Q3's behavior on this issue.

I have gone full manual already just to stop the Q3 from going below my desired minimum shutter speed. Unfortunately, this introduces other issues that I and others have mentioned earlier in this thread.

ETTR makes sense only at base ISO.

Why not raise the Auto-ISO value to the maximum?
