Nikonos IV-A meter question

Factual Questions
1

Nikon itself no longer repairs the Nikonos IV-A, but last year I took mine to a Nikon-authorised repair shop for an overhaul. The exposure is indicated my an LED in the viewfinder. When the exposure is correct, the LED is supposed to remain lit. In case of over- or under-exposure, the LED blinks. Before I took the camera to the shop, the LED remained lit when exposure was correct. Now, it blinks no matter what lighting conditions or aperture I choose.

I did take some non-underwater photos with it last Spring, and they were exposed correctly.

[ul][li]Could it be that the exposure is being correctly set, but the LED circuit is not functioning properly?[/li][li]Is the exposure not being correctly set, but I just got lucky with my aperture setting when I took the photos?[/li][li]Is there another reason why the LED might blink; for example, weak batteries?[/ul][/li]It doesn’t really matter, since I have a Nikonos V for using underwater; but I hate having a camera that’s non-functional (or at least, not functioning properly).

By all means, check the battery first.

Is this an auto-exposure camera, and normally only blinks if the lighting is out of range? Have you tried taking shots that are obviously and intentionally mis-exposed? - how did they turn out?

If pictures are coming out OK, you may want to just ignore the blinking. Failing that, go for f/8 and bracket like mad. :smiley:

Yes, it’s autoexposure; a situation that was remedied with the Nikonos V. (I think the IV-A is based on the EM.)

I haven’t tried to intentionally over- or under-expose an image.
