LVSBB6 Posted June 8, 2013 Share #1 Posted June 8, 2013 Advertisement (gone after registration) Finally received my M240 today and went shooting immediately. Just like previous Ms I figured out most of the camera functions without reading the manual. However it appears the AUTO ISO of M240 isn't functioning properly like M9/Monochrom did under Shutter speed priority, the ISO value does not adjust by itself but rather stuck with the last ISO value I manually picked, even though I select AUTO again before shooting with S mode. Anyone else experiencing the same issue? Quote Link to post Share on other sites More sharing options...

Anyone else experiencing the same issue? Yes, you are correct: differently from M9, the M Type 240 does not adjust the ISO value when aperture and shutter speed are manually selected even if the Auto Iso function has been activated. Apparently this is a design decision based on the request of many (?) users which I hope will be corrected by a future FW. Quote Link to post Share on other sites More sharing options...
jaapv Posted June 8, 2013 Share #4 Posted June 8, 2013 I prefer it this way; when shooting manual you do not want an automatic feature messing up your exposure. The whole idea is to keep the exposure at a fixed value. On the M9 it is the main reason I never use Auto-Iso. On the 240 I may start using it, as to me it is a real improvement. 3 Quote Link to post Share on other sites More sharing options...
Ario Arioldi Posted June 8, 2013 Share #5 Posted June 8, 2013 Everybody has his shooting preference but with the M9 style arrangement one can choose the totally manual exposure mode just deselecting the Auto Iso function, with the present M 240 arrangement there is no way to use the Auto Iso function to adjust the exposure when shutter speed and aperture are manually selected: In my opinion an operating mode which many (?) are considering useful has been removed. 5 Quote Link to post Share on other sites More sharing options...
viramati Posted June 8, 2013 Share #6 Posted June 8, 2013 Though I like the fact that I can set the minimum shutter speed to 1/500 sec I would like also to be able to use it in the way I do with the M9 as the OP suggests. I hope that in a firmware update leica will give us the option . I would suggest we all contact leica technical if this is an issue for you Quote Link to post Share on other sites More sharing options...

Many(?) of us found the existence of auto-iso in manual counter-intuitive and disruptive for correct exposure. There is no place for auto functions in manual imo. An option in menu to set the camera to operate to your taste like David suggests would probably be best. If not, I would urge Leica to keep the improved implementation on the M.

StephenPatterson Posted June 8, 2013 Share #9 Posted June 8, 2013 There is no place for auto functions in manual imo. Exactly, which is why having your M240 set to AutoISO is NOT manual mode. If you want full manual set a hard ISO value, but having the camera arbitrarily select some distantly recorded ISO value from the last time one was dialed in is just plain nuts, not to mention confusing. 5 Quote Link to post Share on other sites More sharing options...
01af Posted June 8, 2013 Share #10 Posted June 8, 2013 There is no place for auto functions in manual imo. That's why you don't select Auto ISO when you want to control exposure manually ... I would urge Leica to keep the improved implementation on the M. An automatic function that isn't doesn't make any sense. The current implementation is nonsense and counter-intuitive. Leica should fix this as soon as possible. 12 Quote Link to post Share on other sites More sharing options...
pico Posted June 8, 2013 Share #11 Posted June 8, 2013 That's why you don't select Auto ISO when you want to control exposure manually Can the M9 AUTO-ISO be turned off? Or does one just set it to the highest speed (1/125) and lowest ISO? Quote Link to post Share on other sites More sharing options...
jdlaing Posted June 8, 2013 Share #12 Posted June 8, 2013 Can the M9 AUTO-ISO be turned off? Or does one just set it to the highest speed (1/125) and lowest ISO? It is turned off when you select a single ISO. If using Auto ISO the highest ISO can be set.....say 800. Then the Auto ISO will automatically select a setting between 160 and 800. 1 Quote Link to post Share on other sites More sharing options...
Rick Posted June 8, 2013 Share #13 Posted June 8, 2013 I would urge Leica to keep the improved implementation on the M. I would urge Leica to return to the logical, working implementation on the M9. 4 Quote Link to post Share on other sites More sharing options...

That is a PITA to me. Just to make sure we are not talking at cross-purposes. The ideal system for me would be: 1. The user defines Auto-ISO (or fixed ISO) in AE mode. 2. In manual mode Auto-ISO as set above is switched off and the camera reverts to a user-defined preset ISO value (which may well be by user choice Auto-ISO). And everybody is happy Edited June 8, 2013 by jaapv Quote Link to post Share on other sites More sharing options...
Rick Posted June 8, 2013 Share #15 Posted June 8, 2013 (edited) So each time I switch from AE to manual I have to disable auto-iso and back again? That is a PITA to me. Yes, you have to disable auto-iso when you switch to manual on the M9... assuming that you had it on. If, you had a set ISO (auto-iso off) then you do not have to do anything. The key point on the implementation of auto-iso on the M9 and why people like it is: When shooting AE and auto-iso, and you decide that you need to lock the shutter speed at, let's say, 1/90 sec, you move the shutter dial off of AE to 1/90 sec and the iso will then adjust itself, up to the max-iso, to provide the correct exposure. This is helpful if, for example, it is dark and you want to freeze motion. You want to choose a set shutter speed to limit motion blur. But, you also want auto-iso to keep up with changing exposure conditions. The M9 allowed the photographer to choose this option. There is no way to achieve this shooting-modality in the new M. It is a broken feature. You can't do it. What happens in the the new M is this: When AE and auto-iso is selected, and you move off of AE to a set shutter speed, you no longer are able utilize auto-iso. Worse, the camera automatically chooses an ISO value for you immediately when you move the shutter dial off of AE. You then have to manually adjust the ISO if, the camera didn't default to the correct ISO value... which it never does in the situation when you need auto-iso. Jaapv, this is a broken feature. It doesn't work. It isn't a matter of something like, "the Leica Man chooses his own ISO and shutter speed." It isn't about shooting style. It is about a feature that does not work. To the point: Auto-ISO is broken (doesn't work) in manual shutter mode. Edited June 8, 2013 by RickLeica 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted June 8, 2013 Share #16 Posted June 8, 2013 (edited) Did you read my post above yours? I understand why it would work the way you describe - but for me, the reason I come from AE to manual is exposure compensation on an individual shot. So manual must disable auto-iso as well.Or I must shut it off as a default. Different approaches - the 240 is better for mine, the 9 better for yours. So both must be catered for.

viramati Posted June 8, 2013 Share #17 Posted June 8, 2013 As you rightly say Jaap each to his own and the fact that it doesn't work for you doesn't mean it can't for others. we all work in different ways and for me the implementation as on the M9 was really useful. I can appreciate being able to set a high minimum speed but I just hope that we can be given the option of having it work in one way or the other. I can't see that it would be difficult to implement in a firmware upgrade Quote Link to post Share on other sites More sharing options...
edwardkaraa Posted June 8, 2013 Share #18 Posted June 8, 2013 I too don't like it that the auto iso remains on in manual. It's an extra step to do when switching from AE mode to manual. I would rather prefer that the camera reverts to base iso when I switch to full manual, as it was implemented in my Sony A900. Quote Link to post Share on other sites More sharing options...
Rick Posted June 8, 2013 Share #19 Posted June 8, 2013 You guys miss the point: When using a set shutter speed there is NO auto-iso. It is broken. It does not work. You can set your M to Auto-ISO, it will say AUTO-ISO, but it will not work. Please, stop debating what your preference is. This broken code. Simple as that. Yes, Jaap, I did read your post, then you changed it after I posted. Did you read my post. 1 Quote Link to post Share on other sites More sharing options...

If you had started with the M240 do you think it would make a difference? I'm spoiled by the M9 and find some things inconvenient too. Quote Link to post Share on other sites More sharing options...
