viramati Posted July 11, 2014 Share #101 Posted July 11, 2014 Advertisement (gone after registration) All I will say is that auto-iso in manual mode is a godsend and a useful tool for me when doing street photography. In this scenario (at least for me) a fast shutter speed and a good DOF are more important than a low iso and IQ. Link to post Share on other sites More sharing options...

FMB Posted July 11, 2014 Share #102 Posted July 11, 2014 Dan, If you are shooting with a fix value of ISO, only changuing to ISO AUTO you have: MAX ISO: 800 SPEED: 1/f Man. Mode : Previous ISO. (the one you were using as a fix ISO). It is a quick position to go for street photography. Francisco. Link to post Share on other sites More sharing options...

I have been using auto iso in manual mode for years now starting with the Nikon D70 then D700, various fuji's and the M8 and M9 and now with the Sony A7 and finally it works again in the M(240) Link to post Share on other sites More sharing options...
lct Posted July 11, 2014 Share #104 Posted July 11, 2014 The "Previous ISO" option is buggy so far. Better read it as "200 ISO", in my M240 at least. Link to post Share on other sites More sharing options...
FMB Posted July 11, 2014 Share #105 Posted July 11, 2014 NOP. It is previous ISO. (My camera repeats the fix ISO previously set, even the camera hadn't be used with that ISO ). Francisco. Link to post Share on other sites More sharing options...
lct Posted July 11, 2014 Share #106 Posted July 11, 2014 My camera repeats the fix ISO previously set So does my camera as well. I did not notice that the camera selects the "previous manually chosen ISO speed" so there is no bug there sorry. Link to post Share on other sites More sharing options...
Exodies Posted July 11, 2014 Share #107 Posted July 11, 2014 Advertisement (gone after registration) Before you select auto ISO, remember to select the fixed ISO you want to use when you change the shutter speed in a certain way. Link to post Share on other sites More sharing options...

Hi Francisco, Later today or tonight I will post something very specific for you, either in this post or a private email. Dan Link to post Share on other sites More sharing options...
FMB Posted July 12, 2014 Share #109 Posted July 12, 2014 Sorry but I don't understand this setup, could you explain again. I have been using auto iso in manual mode for years now starting with the Nikon D70 then D700, various fuji's and the M8 and M9 and now with the Sony A7 and finally it works again in the M(240) David, If you are shooting in "A" mode with ISO non automatic (It means with one of the values numerics of ISO) you can change quickly to ISO "AUTO" (without to introduce any parameter). That means your camera is in the mode "Factory"-" AUTO": Max ISO 800 - Shutter speed 1/f. Again in the inicial position y you put AUTO and change from "A" to manual mode, you have this Automatic ISO: (Nominal Max ISO 800) - Shutter speed, the one selected for you and because your Auto ISO manual is in mode "previous ISO" your actual max ISO is the one numeric you previously had in the "A" inicial position. Sorry, David, my pedagogy doesn't reaches far more. (May be you are in a worse mess tan before) Francisco Link to post Share on other sites More sharing options...
FMB Posted July 12, 2014 Share #110 Posted July 12, 2014 Again for David, Of course always speaking about Auto Iso manual mode of Leica M, wich has ON and PREVIUOSE ISO options. I don't know what happens with the other cameras. Francisco. Link to post Share on other sites More sharing options...
wparsonsgisnet Posted December 26, 2014 Share #111 Posted December 26, 2014 Picked u my M(240) on Wednesday and only today figured out that Auto ISO needs the shutter speed set to A(uto). I missed this in the manual and also in the first part of this thread. Just slow, I guess -- the new M made me forget how I used to do this. Tonite, I will sleep! Nice camera. Took some nice shots today (posted a couple in the 240 User Group). Tomorrow, I'll play with the Auto ISO -- now that I can make it work. I like the sound of the shutter. BUT, I really want Leica to give us a silent shutter. Best regards to all, Bill Link to post Share on other sites More sharing options...
Jeff S Posted December 26, 2014 Share #112 Posted December 26, 2014 Picked u my M(240) on Wednesday and only today figured out that Auto ISO needs the shutter speed set to A(uto).

wparsonsgisnet Posted December 26, 2014 Share #113 Posted December 26, 2014 So, I've been playing with the M and can't understand the change in the ISO setting software. On my M8 and M9 (sadly, now gone in trade dot my dealer), if I set ISO to auto and set the shutter speed to, say 1/250, which is needed for much of my dance photography, the M8 or M9 would set the ISO accordingly. On the M9, if I do the same thing, the M uses the factory setting of ISO 800 as the max. I've played with the ISO settings, including 1/focal and 1/180 with max of ISO 3200. If I set the shutter to A(uto), the ISO changes as I have directed. If I select some specific shutter speed, the max ISO changes to 800. Is this how it is working for everyone else? Do I need to upgrade from 2.0.0.12 firmware? I see 2.0.1.7 out there. Gonna get that. Thanks, Bill Link to post Share on other sites More sharing options...
wparsonsgisnet Posted December 26, 2014 Share #114 Posted December 26, 2014 Yeah, OK. The new version 2.0.1.7 gives me the auto ISO that I expected. Guess that's what the notification about the 'new sw is here' was about. Complicated, tho. You gotta set EVERY parameter to make it work. Gonna see what max of 6400 is like.

jmahto Posted December 26, 2014 Share #115 Posted December 26, 2014 Gonna see what max of 6400 is like. Best to all -- Happy New Year, -Bill Be prepared to see banding if you lift shadows at that ISO. But I guess that is part of CMOS sensor type. I am perfectly fine with ISO 3200 though. Although shadow details are gone by that ISO. To see how much shadow details we loose, see the following crops. First at ISO 200 and the second at 3200 (these were the darkest part of the scene). Brighter areas are much better (and acceptable for any size printing even at 3200). Happy New Year and enjoy shooting. Welcome, dear visitor!

profus Posted January 8, 2015 Share #116 Posted January 8, 2015 The exposure compensation dial provided by the new firmware can be considered as an ISO dial.Set auto ISO, manual shutter speed, manual aperture (of course), then rolling the thumb wheel will change the ISO. Perfect! Couldn't be better! Really do not see, what's not to like about it?! Keep your shutter speed and aperture to what you want and then let camera choose ISO for you - but with possibility to override it and make exposure compensation ( e.g. - 1.0 E.V would set half of that ISO value camera "intended" to use ) Doing like this you can preserve highlights, if that is what you are concerned about... Exactly as I would have designed it! Link to post Share on other sites More sharing options...
