problems with NPC back for ETRSi, please help

[konstantin_kovalenko]

i'm having problems attaching/using my NPC polaroid back for ETRSi.

very seldom i'm able to adjust the screw on the back to be able to

attach the back to the camera, wind the crank and release the

shutter. usually it takes about 10 minutes of fiddling with the

screw before i can get the back on the camera and than crank

wouldn't wind or shutter wouldn't work. Most annoying case if i can

get the back on, wind the crank, release the shutter and then I

won't be able to wind the crank again.

the camera is set in multiple exposures mode according to the manual.

when the back works, the screw is almost all the way out and some

adjustments (1/8 of the turn in some direction) actually make it

fall out.

i wonder if my problems related to the fact that the screw

is not secure enough and some shaking or releasing a shutter shifts

it so the crank wouldn't work? is it possible and do i need a longer

screw? what am i doing wrong? does Bronica's own polaroind back has

this pesky adjustable screw or is it the same pain in the neck?

 

thank you.

I don't know how to help you with your problem, except assure you that there's no screw on Bronica's Polariod back.

I have a Bronica back, but can't get the shutter to fire either.

There is nothing on the Bronica back to adjust..........that I can see anyway.

Hope you've solved your problem by now...

 

My Bronica polariod back is a little fiddly to fit when I have the prism finder in place, but really clicks right in. Just like a regular magazine, only wider and flatter.

 

There are no adjustments.

 

Set the little lever thingy to multi-exposure, wind the crank, remove dark slide, shoot.

I've never had any difficulty with it - of any kind.
