Overgaard Posted October 7, 2013 Share #1 Posted October 7, 2013 Advertisement (gone after registration) Anyone know the reason the M 240 takes longer to shoot at 1600 and 3200 ISO? Link to post Share on other sites More sharing options...
Advertisement Posted October 7, 2013 Posted October 7, 2013 Hi Overgaard, Take a look here High ISO delay. I'm sure you'll find what you were looking for!
dwbell Posted October 7, 2013 Share #2 Posted October 7, 2013 Needs some time to generate all that green cast I guess? Link to post Share on other sites More sharing options...
lct Posted October 7, 2013 Share #3 Posted October 7, 2013 I've got the same startup times in classic mode more or less so you mean in LV mode i guess. If so, i don't know sorry. Link to post Share on other sites More sharing options...
Paulus Posted October 13, 2013 Share #4 Posted October 13, 2013 Beats me, a burst of shots at c is slow in the high regions, but mine already starts at 1250. 1250,1600,3200,6400 are about three times as slow as the 800 iso... Link to post Share on other sites More sharing options...
gravastar Posted October 13, 2013 Share #5 Posted October 13, 2013 Just a guess.... that the noise reduction at high ISOs is more aggressive/complex and takes longer to process? Bob. Link to post Share on other sites More sharing options...
Guest odeon Posted October 13, 2013 Share #6 Posted October 13, 2013 I think, the processor isn't enough. We can see it on EVF and high ISO delays. For all that, i never dislike the processor. I know, the better processor means less battery life. Link to post Share on other sites More sharing options...
Shanghait Posted November 12, 2013 Share #7 Posted November 12, 2013 Advertisement (gone after registration) I also experienced this. But even at lower ISO's this camera seems less responsive than the M9 or MM. Is anyone else find this? When I take shots in rapid succession, there seems like a huge delay VS the older models.

jaapv Posted November 12, 2013 Share #8 Posted November 12, 2013 Not if you set exposure to classic mode. Link to post Share on other sites More sharing options...
jip Posted November 12, 2013 Share #9 Posted November 12, 2013 Not if you set exposure to classic mode. For this reason I never used the 'advanced' light metering. I don't want my sensor to be continuously 'on' I want it to perform as close to my M9 as possible... so classic for me. It has always worked for me so why now switch to 'advanced'...

lct Posted November 12, 2013 Share #10 Posted November 12, 2013 One cannot stay in classic mode when using R lenses with LV/EVF. Link to post Share on other sites More sharing options...
jaapv Posted November 12, 2013 Share #11 Posted November 12, 2013 You do not need to - THE LV/EVF Will slow you down anyway Link to post Share on other sites More sharing options...
-Lss- Posted November 12, 2013 Share #12 Posted November 12, 2013 Just a guess.... that the noise reduction at high ISOs is more aggressive/complex and takes longer to process? This is a likely cause depending on how much slower the camera is (I have never held the M in my hands, so I have no idea about the responsiveness). What I think may take that extra time is a dark frame capture i.e. there may a sensor read with the shutter closed. It's difficult to accept that noise reduction processing itself would tax the system so much that shooting gets slower. There should be sufficient buffer for shooting a few frames with any processing. Link to post Share on other sites More sharing options...
jaapv Posted November 12, 2013 Share #13 Posted November 12, 2013 Actually the noise reduction is pretty minimal. Link to post Share on other sites More sharing options...
-Lss- Posted November 13, 2013 Share #14 Posted November 13, 2013 The perceived noise reduction seems indeed fairly minimal compared to competition. What exactly happens under the hood is however not public information as far as I know. The observed high ISO delay suggests that something is going on. It is likely related to noise reduction or some other sensor issue they have solved this way. Or perhaps they just added a NOP loop to confuse users.

georg Posted November 18, 2013 Share #15 Posted November 18, 2013 It's no noise reduction, they reduce read-out-speed of the ADCs to reduce noise inherited by the amplification/conversion-process. Link to post Share on other sites More sharing options...
-Lss- Posted November 20, 2013 Share #16 Posted November 20, 2013 That would be pretty slow read-out speed (in this thread: "1250,1600,3200,6400 are about three times as slow as the 800 iso"). It would be interesting to experiment with the camera at various shutter speeds, not to mention use it. Link to post Share on other sites More sharing options...
