Long exposures with high ISO?

Unfortunately I have only an additional question: Will Leica ever produce a camera without LENR ? Or at least with a switch to turn LENR off if a user does not want to use it ? Or more M10 specific can the LENR in the M10 be switched off ?

 

Regarding the M10 I do not know, but I assume longer times (up to one hour) will be possible. (like my SL) You should download the manual and check there (it will probably be mentioned).

 

The problem with LENR is that after the main image a second "black" image is taken to have an image for correction of the sensor noise. It is a nice idea, but doubles the time for each and every longtime exposure.  (LENR = longtime exposure noise reduction)

Sorry I realise I didn't fully answer your question. I was able to get above one minute but it's definitely ISO limited.

 

-At ISO 100 I could get well past 2 minutes. I haven't had time to find the actual max exposure at this ISO though.

-At ISO 800 it's limited to 60sec

-At ISO 1600, it's limited to 32sec

-At ISO 3200, it's limited to 16 sec.

Just a quick question. Is it postible to do over 1 minute exposure time in all iso settings? I remember the M240 having a limited exposure time on higher ISOs. I live in Greenland and like to do nothern light images. Thanks.

 

Ah, I was about to post those same questions this morning!

 

Both answers are helpful, the 'T' mode is going in the right direction but once again the M10 is a disappointment to me for the long exposure capability I want.

I just noticed today in the store that with the M10 you need to hold down the release button on B instead of press it once to start and press it again to stop as on the M 240 or M9.

 

I don't think this is how Bulb works on an M240. You have to hold down on the shutter.

sorry, I made a mistake. On my M240 I always used the Bulb mode together with the self timer. I just checked the manual and there it is mentioned that it works different with the self timer. If you use it without the self timer then you have to hold down on the shutter.

OK here's the matrix. Found this out because theres a new T mode, accessed by holding down the focus button in bulb mode.

 

125 sec max - ISO 100-400

60 sec max - ISO 800

32 sec max - ISO 1600

16 sec max - ISO 3200

8 sec max - ISO 6400

 

 

Can we use self timer delay to create a brief few seconds between the shutter button being pressed to when the long exposure starts?

 

Does anyone use the cable release? Using the cable release, is the M10 still bound by the above matrix?

I don't have the M10 but judging by my experience with other Leica bodies I am sure it works the same way as above matrix with cable release. Right now there is no  fix for this.

 

So it makes me wonder about something. I wonder if there is any direct way we could contact Leica and request longer bulb mode? I flooded these forums for years with M 240 about it's limitations with bulb mode. Sadly nobody listened and it did not work out as M10 still have limitations. Granted with slightly improved limitations. But I still don't see any reason why M10 could not handle long exposures just as well as every single other camera body out there. More and more I am convinced the real reason for omitting bulb mode is simply negligence. If enough of us would show interest about bringing bulb mode to M10 perhaps Leica would listen?

I believe it relates to the sensor overheating at high ISO and long exposure

I guess I have trouble believing in this reason anymore. It may have been true for CCD sensors where overheating issues were a serious problem. But it has not been true for many years with CMOS sensors.  I am thinking it's more about Leica's inability to tolerate hot pixels. Or simple case of customer negligence. All the cameras I have used, does not matter if it's mirror-less or DSLR, none of them have had issues with hot pixels. Even if they have few hot pixels they are so easy to fix in post-processing. Leica seems to have zero tolerance for hot pixels. Even S007, which is a massive camera with massive sensor, with a massive heat sink under the sensor, also has the same weakness. Is Leica afraid that a 5 minute exposure would somehow break the camera and would generate a negative revenue? I have never heard a CMOS sensored camera stopped functioning because of long exposure. Besides if they overheat it's easy to implement an overheating protection (à la Hasselblad X1D). Assuming you don't use it in the Gobi Desert. How does Fuji/Sony/Nikon/Canon/Panasonic/Olympus can do it, but Leica cannot? If it's really the sensor overheating (CMOSis) perhaps it would be time to change the sensor manufacturer for M11...

 

And I am really trying to be constructive here. I really wish there was a solution for this. I think there are enough of others who would want the same thing as me...
