    Long exposures on an RZ67 - how?

    Hi all,
    So I went out on a test drive with my new RZ67 last night, just trying to get used to the controls, familiarize myself with it, etc. Other than shooting a whole roll with the darkslide in (not sure why it lets me fire the shutter with the darkslide in vertical mode but prevents me from doing so in horizontal...), it went well.

    However, I can't quite figure out how to do long exposures. I know I have to set it into a special mode for longer than 60 seconds. I've read up on the manual but am still confused.

    So, let's say I want to do a 4 minute exposure. What's the simplest way? It seems like I need to set the lens to "T" no matter what. Okay. I can then put the cable release into the lens. I then fire the shutter on the body, and the mirror goes up but the shutter does not fire. I then open the shutter when I depress the cable release. Fine so far.

    However, the shutter doesn't close when I let go of the cable release. I can get it to close only by disengaging the "T" on the lens. But that shakes the camera.

    Am I doing something wrong?

    I am not familiar with thw RB camera, but on my cameras/lenses the Bulb (B) setting releases the shutter as soon as you let go of the cable release. With the Time (T) setting you press to open the shutter and then press again to release the shutter.

    Hope this helps

    You are doing everything right. Because it is a very long exposure using your fingers on the lens to disengage the T at the end does not really introduce any vibrations picked up on film due to the low light levels. Unlike the RB, you can't use the B setting for long exposures because it is a electronic shutter and it starts giving a high pitch warning signal if used for exposures longer than 50 sec. Use B for shorter exposures and T for longer ones. Also T is fully mechanical and does not use any battery power to keep the shutter open like B does.

    Another trick for ending a long exposure that view camera folks use it to cover the lens with the lens cap at the end of the exposure, you can try that if you want and then disengage the T button once the lens cap is on.
