Not simple! You have to do two things, go to manual and turn off Auto Iso. This is annoying, if You turn from automatic to manual from case to case in diffucult light situations.

HI Elmar

I think this is why it happened.

Of course, nobody told Leica how much they liked the way it worked in the M9 - it was only people saying how they didn't want to have to change to a specific ISO who complained - hence the change.

 

I really think it's likely that something will happen about this - hopefully we'll all get what we want!

It's just so arbitrary the way the M240 chooses the last manually set ISO value when you switch to Manual. You could shoot for days and days in Aperture Priority with AutoISO, powering on and off numerous times, but the moment you dial in a shutter speed the camera will call up that old ISO value. Crazy.

Have found this so at least you can set a minimum shutter speed of 1/500s. I can live with that

I can't. 1/500 is not fast enough in some situations.

Seems like this is by default not by design. If it were not for the fact that it's in the Manual it would be a bug...

So who complained about the matrix ISO display in the M9... :confused:

I could care less about all of this. Auto ISO is my snapshot mode. Otherwise, I want to control ISO/f/shutter. First thing is to go change out of Auto ISO and set the ISO yourself. So, I don't care how it behaves in anything but A. It seems odd to me to use Auto ISO in anything but A.

 

This is all definitely on my don't care list.

Auto ISO with manual shutter/aperture is not a mode I use often, but is useful on occasion. The M9 does this very nicely and the capability is virtually an industry standard. Seems a shame for Leica to improve high ISO performance in the M, but at the same time reduce the capability of Auto ISO.

Jono-

 

You may have answered this, but in your testing did you use Auto ISO much? If so, in what photos you have posted, did you actually use AutoISO?

 

Frankly anything auto I leave to the RX1 and 5D3 as I got the M for Manual use.

Did I say this was a manual approach? Has your Camera a position on the shutter wheel saying "M" or "Manual"? No, there's just a speed and that's what I want. I use AUTO-ISO as this way it is a very fast method to avoid motion blur in fast changing light conditions. If it'd overexpose, I correct my shutter speed. If I want adjustment I use exposure compensation. It's as simple as that, but maybe it isn't old school enough for some of you folks.

 

If I want manual (and I do that at times) I set the ISO value myself of course, I won't put it to AUTO-ISO obviously, I can't see where this is misleading. Of course, if I were photographing trees in daylight exclusively I wouldn't see the point either.

 

I just want to echo insomnia's point which I fully am in line with, I am not against controlling all 3 variables (Shutter, aperture, ISO) manually, its just that if I wanted to control the ISO manually, I would have changed out from Auto ISO to set it manually. Why I feel it's a bug or some would say a design flaw is that it says "Auto ISO" in the selection, but it's not actually true; if you are selecting the shutter manually. Maybe I am used to all other similar implementation of Auto ISO (Canon, Nikon, etc..including the M9.

 

I hope Leica hears us and have a fix for this in the next firmware update.

I can't. 1/500 is not fast enough in some situations.

 

I tried this approach, setting the minimum shutter at 1/500 and a MAX ISO at 1600 in the Auto ISO option. However, I found that if the lighting is insufficient to support the MAX ISO (1600), the M240 will lower the shutter speed regardless of your set minimum shutter. In my test case, it dropped to 1/45. Only when the lighting is sufficient to maintain at correct exposure at 1/500 would this work.

 

I can only assume the M is trying to give priority to a correct exposure rather than minimum shutter. So, I get a motion blurred image...with correct exposure. Nice huh :(

HI There Lou

I use Auto-ISO most of the time - I'm with the others here, the change from the M9 is undesirable - but it's a result of user requests! I really hope and expect that the TAV mode will be reinstated in a firmware update.

 

all the best

Are you also saying that the maximum iso setting possible is 1600 in Auto-ISO which would seem strange as the M9 goes up to 2500!!! what are they playing at

 

Jono as one of the beat testers it would be great if you could point this out to leica

I just got the M and am still getting to know it. I'm so glad I found this thread. It definatly worked more intuitively on the M9. This was driving me crazy. Motion blur is the culprit here. Leica please allow us to choose how auto ISO works! It's the only fair solution.

I spoke to someone at the Leica store in New York and also read a review that said this will definitely be changed in a future firmware release. My M is being delivered next week so I haven't tried it - but I thought it had already been fixed.

 

You will be able to use Auto ISO when in full manual mode.

Awesome! It's a wonderful camera. I don't notice the extra size and weight. Are you from NY? I live in Queens Village. Enjoy, I'm sure you'll be happy with it. Thanks for the info!
