B0tt0mline Posted February 23, 2022 Share #1 Posted February 23, 2022 Advertisement (gone after registration) Hi guys, I got my M11 and have some questions regarding the AUTO ISO (had no issues with it in my M10 or Q2): I have set the max iso to 25.000 and the shutter speed limit to 1/250s. Still, when I shot some pictures yesterday the M11 raised the ISO instead of going to the limit of 1/250s (it always takes 1/360sec instead). Do I understand anything wrong? Is this a bug? Thanks, Alex Link to post Share on other sites More sharing options...
Advertisement Posted February 23, 2022 Posted February 23, 2022 Hi B0tt0mline, Take a look here Shutter Speed - Auto ISO. I'm sure you'll find what you were looking for!
wdahab Posted February 23, 2022 Share #2 Posted February 23, 2022 Speculatively, I believe that the M11 will futz around with speed and ISO to get the most precise combination for the light reading. Since the shutter speed and the ISO have discrete points they can hit, it may have been that 1/360 and the chosen ISO was a better choice for the light conditions than 1/250 and a lower ISO would have been. Because you set max ISO to 25000, it will always assume you're okay with any ISO in that range. 1 Link to post Share on other sites More sharing options...

Thanks, Alex I would think that is another bug. For example, setting the shutter speed limit to 1/60 will be 1/80, 1/125 will be 1/160, 1/250 will be 1/320, etc. The slowest shutter speed is always 1/3 stop higher than selected. Could you please report it? Thanks! Edited February 23, 2022 by SrMi 1 Link to post Share on other sites More sharing options...

wdahab Posted February 23, 2022 Share #6 Posted February 23, 2022 Oh okay, yeah if it's doing *that* then it's a bug. I thought you meant that sometimes it was 1/250 @ 10000 and other times it was 1/360 @ 12500 or something like that (making up the ISOs). But if it's only ever hitting 1/360 and never going to 1/250, that sounds weird. Link to post Share on other sites More sharing options...

chemist Posted April 4, 2022 Share #8 Posted April 4, 2022 Is there an overlay by exposure compensation ? up to 3 values? Link to post Share on other sites More sharing options...

ianforber Posted April 5, 2022 Share #10 Posted April 5, 2022 Not for me. I have the Auto ISO set to 1/250 and it still defaults to a minimum of 1/320. For what it’s worth, I have no problem with this behaviour even if it isn’t quite what is supposed to happen 1 Link to post Share on other sites More sharing options...

Also not a big issue for me neither. Has anyone filed the bug with Leica? 1 Link to post Share on other sites More sharing options...
