How do i open a Nizo integral5 lense?

[Mattan]

Hi!
I got my Nizo integral5 now, and i want to start filming..but i have a problem.
i looked into the viewfinder and i can't see anything but black.
then i took the camera and point it on a light source(my desk lamp) and only then i could see somthing but it was really out of focus and without shape....then i lookes into the lense and i notice that it seems there is a small plastic piece in it( i think it's from the lense itself).
so i want to open the lense somhow and get that piece out of it.
can you help me?

Thanks!

The quick answer to your question is DONT.Lenses are very specialised and unless you know what you are doing you will upset all the settings on reassembly.
Your poblem seems to me to not be with the lense but something has become dislodged behind it,possibly something to do with the AtoD filter.Another problem could be that the shutter is actually stuck in the closed position.This can be tackled with the right small tools but what you may find once you are in there maybe something else alltogether.Hope this has given you some guidelines.
Best of luck.

I'm sure it's a plastic piece stuck inside.
i tried to shake it(very gentley) and the piece moved, now i see a bit more, but i'm sure it's somthing inside...
can't i open it somehow?
thanks again,

Mattan:
The camera was built so thereby it can be 'unbuilt'.Look for very (very) tiny screwheads inside and outside of the camera and then VERY CAREFULLY remove them and see what happens.
Check also around the camera gate assembly within the camera.In fact,thinking about it,this would be your best place to start.The gates are usually automatically jigged in by the fixing screws.Removing the gate just might reveal something.I must warn you however that reassembly of the screwheads must be done without damaging the heads or else you will ruin every cartridge you load. :roll:

All this is for guidance only,and I accept no responsibility for any damage you incur whilst investigating this problem.A proper photgraphic or clock engineer may be the best way forward

I wasn't thinking about unbuilt it.
i tried to play with the zoom, and then suddenly it stopped showin black , the picture was clear and it looked great, but then i noticed i can't change the zoom anymore, i tried a bit harder and then i changed the zoom but again the viewfinder showed black.
so there is a spot on the zoom ring when i can see clearly...
anyway,I find a photogarh store here, and i'll bring them the camera soon.
Thanks very much.

Mattan.

[......then I tried a bit harder...]

This seems to be it,there was a jam somewhere on the zoom mechanism and you forced it breaking something off in the process.Photo shop here you come. :oops

The whole story sounds like the problem whe had a while ago. OUB do you remember this Nizo S80 which lost its viewfinder mirror?

So the problem would not be inside the lense. It is then about 1 or 2 cm behind the macro/wide angle marks of the camera front: the viewfinder mirror chamber. As already guessed the problem can not be the shutter, a shutter problem could not be observed in the viewfinder anyway. Therefore hands off the film gate and from the screws in the surrounding region.

Achtung: To be safe you follow Barrys recommending regarding a professional repair . But if you are more from the risky sort of man you think about this:

In this country (de) you would get several working Integral - 5s for a repair by a technician...

So with some skill it is relatively easy to open the camera but be very careful (screwhead damage!), use good tools, do not hurry, do not forget what you did.

Marschplan:

1) Open the cartridge chamber ( back-plate with all (that with the Nizo comments on it): 2 metallic screws: one small, one long. After taking out this plate you have access for:

2) Opening the major plastic control plate of the camera: 3 (?) long inner screws behind the plate from 1) one additional short screw is actually covered by a small plastic part (left hand side from the intervall time) this can easily be removed by simply using your fingers. Carefully remove the loosened major plastic control side plate.

3) Then you see the impressive back of the cameras main circuit board which can be taken out partially (cables!) by hand. Care.

4) Having done this the "intestines" of the cam appear. In front of the viewfinder tube (can also be removed from inside, very small black screws) is a mirror holder (45 °). I assume the mirror has fallen off this holder and it could be fixed again with glue. Avoid to touch the sensitive mirror surface by hand...

Mlke:
Must admit the shutter mirror angle slipped my mind.Thinking about it though I reckon you are right.
I endorse wholeheartedly your instructions on your post.

Hey Mike!
I printed the message you posted, I set for half an hout with the nizo and some tools and did exactly what you said and it workes!
Perfectly!!!
Thanks very much.. now I can see clearly through the viewfinder.
8)
Befor I order film i have to find out if the camera really works....when I click the master switch(and look into the cartridge chamber) what am i suppose to see?
does the circle in the middle should be moving, because it doesn't...

Thanks again!
Mattan.

Congratulations Mattan, cam surgeon. Hope it will last...
To your question: If you look into the empty cartridge chamber towards the filmgate you should see the shutter opening and closing highfrequently at triggered 18 or 24 fps. Lens directed to a light-source > better visual.

Do you know why there is a 6 + 9V green-led button at the camera? Is your servomotor for the aperture control also relatively noisy (humming sound)?

Best. Mike
