Hi, I was wondering if anyone has come arrose this issue before.

I have a D70 with a Nikon 21-80mm lense.

I ahve recently been taking some pictures and using the lens switching
between auto and manual focus.

The fault is that when ever I have the F-Stop below 16f the mirror does
not stay up correctly and allows some light in. The smaller the F-stop
the less the mirror holds. If I change the f-stop above 16 then the
problem reduces untill I get to the highest f-stop 22f and the mirror
remains up correctly.

I have also tested with no lens and the fault does not occur.

If anyone can shedsome light (no pun intended) on this issue I would be
very greatful.

Regards,

Mark Seymour

Sound like you are using the aperture ring on the lens. With the D70, you
shouldn't be doing this. You should set the lens aperture ring to the
largest value and set the aperture for the shot using the front command
wheel.

No you don't. Nikon doesn't MAKE a 21-80mm lens.

Doubtful, but presumably you meant 28-80mm.

If the mirror isn't staying in place correctly, then it's broken. If
the mirror isn't in the correct position, then you also would see the
problem through the viewfinder, which will not work correctly at all.
The only answer is to get it fixed.

I am more likely to think that Ed's response is the correct one.

If moving the aperture ring away from minimum does anything other than
put "ERR" on the LCD and make the camera refuse to fire, then it's broken.

You've all done quite well IMO - in deducing that the OP has a problem
with a camera. Very entertaining - thanks.

So my very clever friend what is your guess?

If there was a coherent question, then an answer might be possible.
Trying to decipher such a cryptic description of a problem is hopeless.
I wasn't going to bother with a guess - I was kind of hoping that
someone might ask the OP to clarify his question or that the OP would
respond to some of the replies that he had received with a bit more
information.

fEE is displayed, not Err when the aperture ring is rotated, and from
what the OP seems to be saying, the shutter seems to be working but not
properly, so that ain't it at all.
Reports of D70 shutter failure indicate that problems start intermittently.
Hard reset camera (small button on base).
Update to new firmware - if it's a D70 with original firmware.
Check mirror box for something obvious (hair etc) jamming mirror
mechanism. If it is that, then think very hard before just yanking it out.
If still problems, save $300 if out of warranty, and take camera in for
repair.

Often seems to be the way, the question is asked and the OP never pokes
their head back in to reveal the fix.

I doubt it. To my knowledge, Nikon has never made a 21-80mm lens.
