>30s exposures using k-5 intervalometer?

So i was curious if its possible to set up the k-5 intervalometer to do "bulb" length shots, i.e. greater than 30 seconds. anyone know if you can do this?

I should say no, you cannot. In the menu set-up you can control inerval between shots, number of shots and start time - not the duration of shots, which you will need to set (or let the camera decide for you) in one the ordinary program modes. Bulb cannot be used together with the interval timer.

I guess you could find a programable cable release that could do the trick for you?

One might even be able to hack a solution to this out of the mp3 player remote method. Instead of just sending one pulse to the diode, create a longer sound file that sends a pulse to open/close the shutter in bulb mode at the interval you want.

Pixel TW-282 is a good solution. Wireless or wired...

Of course, when taking star photos using O-GPS1 and Astrotracer, automatically timed shots exceeding 30 seconds are possible (astrotracer/bulb/MF mode) but sadly that doesn't address the original question...

Are you sure? Don't you have to press OK before each shoot in astrotracer mode?

I bought a YongNuo cable shutter with electronic intervalometer controls that worked fine on the K20 and now the K5. Should work fine for your use - check ebay.

Yes, that's what I meant by 'doesn't address the original question'. You get the longer timed exposures but not the interval shooting, all it does is allow one star field exposure of up to 3 minutes (if the O/P is into that) but it does show that they *could* extend the standard exposure limit beyond 30s in software/firmware if they chose to, and perhaps link it with the intervalometer too (if they chose to). If they did, and locked it to the O-GPS1 (but not to star shots), it would I think increase sales of that.

Actually, the ASTROTRACER maximum timed exposure limit is calculated from the lens focal length, GPS position and angle of camera focal axis data. It can actually be longer than 3 minutes if you are shooting with a wide lens.
