Is it possible to modify a Nikon F3 to add a needle light meter?

I'm having issues with the +- light meter in my Nikon F3. The classic needle meter has always been my favorite, so it would be the best of both worlds to have that meter in my favorite SLR.

Any ideas?

I mean, anything is possible, right?

If you are an engineer whose background is in small electronics, I'm sure that you can find a way to do build and install your own personalized light meter display in the Nikon F3, or any other camera for that matter.

But if you are not an engineer whose background is in small electronics, then no.

Technically, it's certainly possible to swap out one component like what is essentially just a voltage display, out with another one but realistically, you would probably need to cannibalize several or numerous F3's and several swing needle meter cameras in order to figure out how. The new meter would have to meet the exact same electrical needs as the F3's which would be a challenge because LCD meter read-outs consume less power than swing needle read-out's, which is partly why Nikon implemented this in the F3. You would then need something coming off the metering circuit that bumped the voltage up to match whatever was needed for the swing needle. So these are just on-paper, basic electrical challenges, right? Worse, will be the issue of mounting this device inside a camera that was designed and built for another type of display. The F3 has a very peculiar meter display that incorporates an additional light source just to light it in dim situations. The display also doesn't take up very much space in the viewfinder, whereas 35mm swing needle type displays do. Mounting the display just the right distance from the optics in order to see it in focus will also be a challenge because the device would have to perfectly fit in the footprint of the previous one.

These are just a few thoughts off the top of my head, I'm quite sure there are more issues.

But look, I agree. The F3 is arguably the most popular SLR that Nikon ever built and if you try to tell any Nikon fan that you have a problem with the totally STUPID meter display in it or the lack of different heads that might solve this problem, you will likely be told to go F yourself because love for the F3 is so fervent. I agree though, as an available light shooter who routinely burns at 6400 ISO, having a meter display that requires me to read TINY numbers instead of just a YES/NO kind of simple display and is pretty much invisible in 800 and darker ISO situations, well, this is all just stupid on a professional camera. I have an F3hp but I only use it in daylight or when I don't care about the meter. It feels great in the hand, particularly with the winder installed, it's accurate, it's got a nice set of features, the viewfinder is 100% so you can't go wrong with that, but that meter is just flat out stupid in my viewpoint also.

If you want a swing needle read-out (btw, a read-out or display is NOT a light meter, the meter is a separate device), I encourage you to move backwards to the F2 which has about a million different heads you can mount to the body and get pretty much exactly the display and viewfinder you're looking for. That is what I did. I like LED read-outs so after some months with the F3, I put it back in my shelf and bought an F2sb. You'll want something earlier.

Anyway, I hope all this has been useful and you have a nice holiday season! Happy shooting and please be kind enough to choose a best answer! If you want a needle for your lightmeter, look for a camera model with one. That's how we did it before and that's still how we do it today.

Merry Christmas! Another option is to just use a hand-held light meter like a Sekonic which can meter reflective and incident light.
