metalbernd Posted October 12, 2012 Share #1 Â Posted October 12, 2012 Advertisement (gone after registration) With the X2 set on auto ISO it's possible that the camera take a picture with 320ISO or 640ISO. But when I set it manual I can choose 100-200-ect. Maybe a stupid question but I want to now...... Link to post Share on other sites More sharing options...
Advertisement Posted October 12, 2012 Posted October 12, 2012 Hi metalbernd, Take a look here Auto ISO question. I'm sure you'll find what you were looking for!
noeffred Posted October 12, 2012 Share #2 Â Posted October 12, 2012 I've noticed that as well - when you set aperture and shutter speed manually the AUTO ISO option is grayed out. Strange design choice... maybe something that should be adresses in a later firmware update? Link to post Share on other sites More sharing options...
Mr_Jones Posted October 12, 2012 Share #3 Â Posted October 12, 2012 I've scratched my head about this one too as it seems most useful when you've decided the aperture and shutter speed, maybe someone can shine a light on this. Link to post Share on other sites More sharing options...
yanidel Posted October 13, 2012 Share #4 Â Posted October 13, 2012 Since you set aperture and speed, Leica probably assumes you know what you are doing and don't need Auto-ISO. But yes, it would be helpful in some situations. Link to post Share on other sites More sharing options...
jlindstrom Posted October 16, 2012 Share #5 Â Posted October 16, 2012 Yanidel is probably correct, though need and want are differet things.. ie in most situations this isn't necessary but it could be usefull at times. Hope this gets fixed in the next update. Â --Juha Link to post Share on other sites More sharing options...
wda Posted October 16, 2012 Share #6 Â Posted October 16, 2012 The use of Auto ISO does carry the risk of introducing noise when none is wanted. So if you are in manual mode, it is easy to make exposure adjustments while STILL retaining your chosen ISO and acceptable noise risk.. Link to post Share on other sites More sharing options...
Tonki-M Posted October 17, 2012 Share #7 Â Posted October 17, 2012 Advertisement (gone after registration) the auto-iso is grayed out in manual mode because if you had it on, your manual won't be manual, and your 'manual' exposure will change as the camera will change the iso to 'what it thinks is right' Â an easy example would be if you're shooting against a bright overcast sky. most likely your photo is going to be underexposed. let's say the camera gives u 1/250 f5.6 iso100 so you say, 'hey that's too dark, my subject is underexp' then u manually change the setting to 1/60 f5.6 'auto-iso' when you take the shot, woi-la, your shot is still under exposed, b/c now the camera uses it metering to what it thinks is 'correct' so u get something like 1/60 f5.6 iso400 Link to post Share on other sites More sharing options...
