The fact that this option exists in the menu means it can be disabled. Can you disable it in normal shutter speeds? (i..e not bulb)
If not, there must be a feature that is enabled which needs Long Term NR (in a similar way that you can't select ISO100 when smart range is enabled).
The dark frame subtraction (DFS, long shutter speed noise reduction) option is grayed out in bulb mode. My issue is the DFS is totally broken, because the image is useless on long shutter speeds, say 2 minutes and the image comes out black (the noise reduction isn't working properly).
I see Daniel posted a link to a firmware update today that fixes a bug with bulb mode, so I am going to try that out tonight and see if that fixes this issue. I would rather not be forced into DFS with bulb, but that is okay as long as I can get a useful image from it.
Oh, weird, the older firmware works fine with DFS and my 12-24mm. I wonder if it is related to the manual focus lens I was using (for some reason exposures longer than 30 seconds would be almost black, even when a 30 second exposure at the same settings would be brighter). I might have to look at exif data in my pictures and see if I can replicate the situation with the new firmware.
