N90s W/MF-26 auto fire malfunction?

I have not used my N90s for about a year. When I finally got around

to using it the batteries in the attached MF-26 were dead. I

replaced the batteries and went on to set city, time, etc. After I

had configured it everything seemed okay. I was setting up some

bracketing settings and the camera started to fire the shutter

automatically, I was puzzled. Seems that every time I push any

button on the MF-26 the N90s would fire the shutter.

I held in the button "mode" for example it continues to fire shot

after shot, until I stop pressing the button. I checked to make sure

I was not holding down the shutter release while handling the camera,

and it still happens. I removed all the batteries from the N90s and

the MF-26, in an effort to "reset" what ever happened, the problem

still persists.

 

Any one seen this, and/or have any recommendations for a fix?

Obviously there is a problem with the MF-26. Either send it for service or just don't bother to use it.

It has now become an MF-27 multi shutter release back. Very rare and valuable, allows you to use your nose to trigger the shutter whether you are right-eyed or left-eyed, right- or left-handed.

I guess it needs to be repaired or replaced.

You might try a Q-tip (cotton swab) and some (very little) alcohol to clean the contacts. A little rubbing with a pencil eraser might do the job, but take care not to drop stuff into the camera back.

 

The non-use of your camera may have allowed some residue to coat the contact surfaces.

Mine did a similar thing. Replacing the batteries in the MF26 solved the problem.

I had the same problem when I tried to use the auto-bracketing function. I put in fresh batteries and re-attached the data back, and it seemed to fix the problem.

I carefully cleaned to contacts with a pencil eraser, and VIOLA! It works!

Thank you, everyone for your help.

Well, a couple of minutes with a pencil eraser sure is faster and cheaper than a session in the repair shop. Glad you took THAT advice and not mine.

 

I am continually amazed at the variety and severity of malfunctions that can be caused by a little crud on the contacts.
