Mamiya RZ67 Questions
I am a new user of the Mamiya RZ67 system. I have a pile of equipment I have obtained on ebay and I suspect the problems I am having are related to the PRO I body I have.
I have one RZ lens and One RB lens.
1: The shutter speeds with the RZ lens all work except the Bulb setting...when I trip the shutter, and hold the button, the shutter just opens and closes as if it were set on the mechanical back-up.
The long exposures all work (Up to 8 SEC) and the time exposure setting also works with or with out a cable release. Is this likely a problem with the lens or the body?
Problem 2 is with a Power Winder II I just obtained: (ACTUALLY 2 problems)
One seems to be related to the shutter release button on the camera:
After making an exposure, I have to repeatedly tap the shutter button or slowly turn the button's locking mechanism before the winder will activate.
Problem 2 with winder: If I load a fresh roll and push the start button, it will load and advance to frame 1 okay, but for any subsequent frames, the counter will advance, but the winder gets kinda stuck and keeps trying to finish cocking the camera. If I help it along by pushing on the manual advance lever while the motor is running, as if I am cocking it without a motor, the winder stops clicking and catches up.
As I said, this is all used equipment, new to me, and I am not intimately familiar with the RZ system. I'm trying to confirm that I got a bum Body. Thanks!
There are two things with the winder - you have to make sure the little trap door on the bottom of the camera is fully opened so that the gears can engage properly, and the winder has fresh batteries. This thing is an electro-mechanical device and eats batteries for breakfast. (I rarely use mine, so change the batteries once a year whether it seems needed or not.) You can check out the winder off the camera by turning it on and pressing the 'start' button. The gear should extend and rotate until you turn the power off. If this is ok, then it is probable that you have an electronics issue with the camera body. Being an electronic camera, repairs typically run $300 or more. Good luck.

Yeah, I tried those tests with the motor and it does seem to be okay itself. just goes to show there are few real bargains on ebay. Everything (EXCEPT BULB< WHICH I WILL PROBABLY NOT USE WITH THIS CAMERA ANYWAY) is fine if I just go without the motor. I have a test roll of transparencies out for processing, so truth will be told about where I stand very soon.
I will probably upgrade the body to something newer eventually anyway.
As for time exposures---there's a good reason to keep the 4x5 Field camera handy.

Do you have a manual for the RZ?
I remember that there is a tricky thing with the bulb setting. For anything longer than a minute, you need to use the T setting on the lens. I'll have a look later if you'd like...I need to refresh anyway...
Remember-- on the Bulb setting...the shutter closes immediately, really fast, just like as if the camera was either set at a high shutter speed or else on the mechanical release setting. I am wondering though if there is some specific sequence for shooting in Bulb.
...yes, I found a manual online.

Tom...do you have a new battery in the body?
...Battery, good question. The battery I bought at the shop was supposedly new, but not in a package, though bought from someone I trust...HAHAHAHA!! Also, It was not a lithium battery, but a regular old PX28. The contacts are all clean. I just timed the longer shutter speeds ( 1sec-8 sec) with my trusty old wristwatch, and they all seem pretty okay.
I guess a battery would be logical. Sometimes electronics do strange things with marginal batteries.
PX 28 should be fine, but just check to be sure...
I just tried bulb on my RZ...pressed the shutter button and held it down for a minute. It started buzzing, as mentioned in the manual.
Upon pressing, the mirror slaps (what a commotion!) and upon release the shutter clicks closed (softly, as in a morning sunrise)...
...Ruled out the battery. I guess I need to check against another RZ lens.....by contacts...do you mean outside the lens? They are bright and shiny. I'm not sure about where to find them if I take the lens apart...YIKES!!
I have however had all of the panels off the body ..mostly related to the problem with the motor. I cleaned some contacts having to do with the shutter release, and it seems a little snappier. Everything inside seems untampered with and clean otherwise.
The only panel I couldn't get off was on the side with the hotshoe and the shutter speed dial. I suspect there are some screws under the hotshoe that I couldn't get to. I erred on the side of caution.
...and by the way...the problems are the same before AND after disassembly.

Tom, Lens and camera body contacts can be finicky as i have recently learned. Even if contact are bright and shiny, give them a little rub with a clean linth free cloth, it does not take much for low current signals to get out of whack.
