Mirror Lockup Question on RZ67

[eric_burgess]

I just bought a new RZ67 and am confused on the mirror lockup

procedure. It works fine for me at all shutter speeds except for B

and T.

 

I don't have the Mamiya cable, but I am using a regular cable release

screwed into the lens.

I press the shutter release (locking up the mirror), and then when I

press and hold the cable release (should release the shutter and

leave it open), it opens and closes the shutter very quickly (maybe

1/250).

Reading the owners manual, I thought it would stay open until the

cable is removed.

 

What am I doing wrong???

One more thing - the shutter release button is in the white position - not manual 1/400 setting.

I don't use an RZ (still on an RB), but I checked out the online RZ manual at mamiya.com. Still not sure what it said, so you should check it out and see what you think. Pages 28-30 or so.

 

Seems to say that, on the lens, if you slide the switch near the aperture pointer so that the "T" is visible, you can can press the shutter release to open, then slide the switch back to close. This is a mechanical feature, so it uses virtually no battery power.

 

If that doesn't help you, I hope someone who knows what he's talking about will jump in here!

How long are you waiting before depressing the cable release? The RZ reverts to it's (mechanical) 1/400 sec exposure after 60 secs (following a warning bleep). To override this, perform the mirror lock-up in multiple exposure mode (set the switch which allows the back to rotate to "M") and then select your shutter speed.
