D600 Bulb Photography Issue

I tried taking a long exposure shot last week by setting my shutter speed to "Bulb" and using the Mirror Up setting, so that I could manually open and close my shutter with my remote. However, the camera is automatically closing my shutter after only 30 seconds.


This feature was working in January, which is the last time I did long-exposure photography. However, I have no idea why my shutter is not able to stay open at my discretion any more.


In the Spring, I did have my sensor professionally cleaned...which is the only thing different I've done since January. Could this have triggered a setting to limit the amount of time my shutter could remain open? If not that, what else could the issue be?

Because of the numbers, I gotta ask, 30 seconds or 30 minutes? :)

According to D600 manual page 79, Bulb is supposed to stay open an indefinite time, but you said you were using the "remote". The ML-L3 remote only stays open 30 minutes (page 79). A MC-DC2 cord should not be any issue.

The manual says about MUP, if no picture is taken within 30 seconds, then at at 30 seconds, it will take a picture anyway.

If it was really only 30 seconds, I dunno, but I would be sure the battery is fully charged first. I'd test once without the remote too, to see if that matters. And I'd test once without MUP.

There might be a setting somewhere that tells the camera to stop expecting remote commands after a certain time. I don't have a D600 anymore, but think I've read about the camera's "wait for command" time-out.

Just a hunch. Hope it works.

I have the same or a similar issue. I was taking long night exposures earlier this week. Setting the camera to Manual, exposure to "bulb", then shift the selector to "remote" which changes the exposure to "time --". It would work sometimes, but most of the time the exposure would end after a short period - perhaps 30 seconds, but I didn't measure it (I think it was less). I fully charged the batteries and tried again, but the same issue occurred.
