Another Fujifilm Instax mini 8

Yes another one. Anyone that reads what I post will realise that these little cameras have really become popular with the youngsters within our family. I recently posted about a family get together: The garden gathering and in this post I stated that a young member of the family liked these cameras so much, that she went out and purchased a damaged one and asked if I could fix it for her. How could I turn down such an offer?

And here it is. Needs a little clean and immediately I can see an issue, what I’ve noticed is that the little iris lens protectors that close when the lens is retracted are missing, or not operating and opening properly. Everything else seems to be doing what it should, motor, film transport system etc, however the initial issue reported with this camera was that it’s exposure was sometimes hit and miss, it most definitely all related to the lens issue. A good clean wouldn’t go amiss with some extra attention paid to the light sensor area.

Anyway, enough chat, let’s crack on.

Assessment:

A nice tidy camera, needs a little clean, flash fires, film transport mechanism inside is working and the motor runs. It gives the impression that it is working fine, however….

Here’s a reminder from the young family member who made the purchase, regarding its issues:

I’ve just remembered, I think the advert said something about the photos coming out dark no matter what setting it is on! x

I’d already noticed the little iris mechanism on the front of the lens didn’t open and close when the camera was turned on, so I was going to be looking in this area anyway. But when I looked a little closer and moved the aperture ring on the side of the lens, the relative apertures in the lens were only moving to roughly the half way point, off centre, hence there was no corresponding fully positioned aperture, and in relation to the lighting situation that was presented, they were stuck and blocking the incoming light. In a nutshell there was not a sufficient sized aperture “hole” for any light to get through, resulting in the exposure issue stated above. This needs adjusting. You can see what I mean in the photo below. The lens aperture leaf does not sit central in the lens.

Apart from the highlighted problems above, i don’t believe there are any other underlying issues. So I’m going to concentrate on the front of the camera solely in the lens turret area.

Let’s get on with the repair.

Repair:

The iris issue is within the lens turret so this will need to be dismantled to access the iris.

It was a bit of a head scratcher this one, as I spent a lot of time just staring at the mechanism trying to figure out how it worked. When the iris lids were manually manipulated to the closed position when the turret was retracted all was fine. When the turret was opened up the iris lens did the same, but then if you again retracted the lens the iris remained open exposing the lens. I was thinking it must be missing a spring somewhere and I was about to be proved right.

I found a replacement iris mount that fits within the lens turret. I had this in a spare box and used this as a reference to compare to the old non operating one. Here is where it was confirmed that there was a spring missing and this is why the iris was not operating.

I replaced the old mechanism with the new one and this was installed back in the camera, this now works fine. I have however found a suitable spring for the old iris so I do now have another spare ready should another be needed in the future.

The issue with the aperture positioning has been sorted by ensuring that the aperture ring is correctly positioned in relation to the cog mechanism in the lens turret area. It’s a bit like sorting out the timing belt in a car, it just has to be in the right position to achieve the correct aperture settings.

This sorted, the last thing to do was to give the viewfinder a little clean. You have to be very careful here as the viewfinder is connected to the camera “ready to shoot” indicating light, and there are very fine wires all around this area. Be just a bit too clumsy here and you’d have a difficult soldering project to also add to the original problems. Anyway, no such issues today, the viewfinder was un clipped and prisms and glass cleaned and reassembled. All looking good.

I’m now happy that all the issues have been attended to and I’m just going to reassemble the camera ready for a quick clean. Luckily all the screws that came out went back in with none leftover. Result!

Result:

We now have a nice little unit, all aperture settings are working as they should and the lens iris is operating as it was always supposed to do. The viewfinder has also been cleaned and it’s now a nice clear unobstructed view. It just works.

I’m guessing this camera will be coming away with the owner on a family holiday that we are all about to embark on shortly. I’m hoping to run some film through this soon but I am ultra confident it will work as all the issues have now been addressed.

I’ve just got some film and rattled off 4 quick shots, one of them indoors. Exposures are fine so I’m happy this is a perfectly good working camera.

I’m sure there will be one younger member of the family who will be very happy with her new camera. And may she have many years of capturing good times and fantastic memories. This is what these little cameras are made for after all.

Thanks for passing by, it’s always very much appreciated.
