Ario Arioldi Posted February 13, 2017 Share #1 Posted February 13, 2017 Advertisement (gone after registration) A friend of mine noticed, and I have also verified this on my M10, that above certain ISO the recocking of the shutter is substantially delayed. For instance at 1/4 sec and ISO 800 the recocking time is quite normal but increasing the ISO to 1600 there is a clearly audible delay. At 1/8 sec and ISO 1600 the dealy again is negligible... I have not verified more combinations and I guess it is a feature but, just to be sure, has anybody else noticed the same? TIA Quote Link to post Share on other sites More sharing options...

digitalfx Posted February 13, 2017 Share #2 Posted February 13, 2017 (edited) are you sure he wasn't using the EVF when he heard this difference? ISO has no affect on the shutter, other than changing your shutter speed. Edited February 13, 2017 by digitalfx Quote Link to post Share on other sites More sharing options...

digitalfx Posted February 13, 2017 Share #4 Posted February 13, 2017 (edited) sorry I meant live view. Changing ISO doesn't have any affect on the shutter sound...unless you are hearing a longer exposure due to ISO change. When in Live View, the shutter sounds different Edited February 13, 2017 by digitalfx Quote Link to post Share on other sites More sharing options...

pop Posted February 13, 2017 Share #8 Posted February 13, 2017 This or a very similar topic has been discussed in the German language forum: http://www.l-camera-forum.com/topic/268896-verschluss-ab-iso-25000/ It appears that the M10 takes a dark frame for noise reduction even for relatively short exposure times at high ISO values.

If I set ISO to 100 and shutter speed to 1/250 mine sounds exactly the same as ISO 6000 and 1/250 Edited February 13, 2017 by digitalfx Quote Link to post Share on other sites More sharing options...

Just did another test. This only occurs with slow shutter speeds. If I set to 1/24th at ISO 100 and ISO 6000 I can hear the difference. This only seems to happen at 1/24th or slower. At 1/30th and above I don't experience this. Looks like I didn't read your first post clearly describing the issue at slow shutter speeds.

UliWer Posted February 13, 2017 Share #12 Posted February 13, 2017 M10 manual - English version - p.175: • Following exposures with slower shutter speeds (below approx. 1⁄30s, differing depending on other menu settings) a data processing procedure takes place to reduce this annoying phenomonen that takes the same time as the exposure. This doubling of the “exposure” time can be significant at longer exposure times, and must be allowed for. During this time the camera should not be turned off . At shutter speeds of more than 2s, the message "noise reduction 12 sec"" appears in the monitor. 1 Quote Link to post Share on other sites More sharing options...
edw Posted February 13, 2017 Share #13 Posted February 13, 2017 Now that is interesting! Thank you. I hope Leica offers an over-ride. . Everyone calm down. Yes, I know you are calm, I meant that other person. This is identical behavior to the 262 and 240. There has never been a way to turn it off. Page 169 of the M10 manual or page 83 of the M-D manual or page 182 of the 240 manual. 1 Quote Link to post Share on other sites More sharing options...
