Much to the wife’s annoyance, and because I was feeling a little low and in need of some retail therapy, I’ve purchased this lovely little camera from the Barnardos charity. It looks like it’s been stored in a full Hoover bag, it is so dusty. It has a few dents and dinks, this one is going to be a challenge. I like challenges. I’ve paid the grand total of £17:67GBP for the camera and the standard Zuiko 50MM F1.8 Lens. I think that is an excellent price.

These cameras were produced between 1979 and 1987. I’m hoping I’ll be able to date this actual camera more accurately when I receive it.

This is what the original listing stated:

This listing is for a vintage Olympus OM-10 35mm Single-Lens Reflex (SLR) film camera, bundled with a Zuiko 50mm f/1.8 lens and a leather neck strap. This is a single bundle containing the camera body, lens, and strap, ideal for collectors or film photography enthusiasts.

UNTESTED. This sale is for spares/repairs. There are some marks and cosmetic imperfections. Please see images for more detail.

The standard untested post from the auction sites, but I’m not really bothered to be honest. It’s a charity, and I’m happy to pay for these items as the charity always benefits, and that’s all that matters to be honest.

I have some history around this camera and whenever I see one I think of Bruce Springsteen and here’s why.

Born in the USA was released in 1984, so I can kind of pinpoint the first time I’d ever really heard him, courtesy of my friend David K, when I used to live in a small town in Hertfordshire called Bushey. David had been a school friend, we were now in our mid to late teens, he was working in a restaurant whilst I was in a photographic lab. He introduced Bruce to me and for many months after he first purchased that album, we played it non stop and knew it off by heart, beat for beat, and word for word, we were totally smitten with it. It was the Bruce effect. At this time i would have been about 18-19 years old, and had a very basic Russian Zenit camera, it took some great photos. However, David had recently had a bonus payment at work and purchased himself the Olympus OM10. I was envious, who wouldn’t be? What a camera and this is where it all ties in with our hobby, we loved photography and used to always discuss it with Bruce in the background singing his heart out. It all ties in now, fantastic memories, and a single camera can bring back these memories. Amazing isn’t it?

Anyway here’s some pictures where you can see the amount of dirt, and what looks like some bumps on the outer edge of the lens.

Here’s some information regarding this camera:

The OM10 was the first consumer OM series body. Launched in 1979 it accepted the full line of OM lenses and most of the OM accessories for a lower price. The lower price was reflected in the construction of this camera and the features available, however, it was still a very competent performer and it reflected the elegant lines established by the compact OM-1 and 2 designs. Early production runs of the OM10 have known malfunction issues with electronics, metering, and shutter magnets. Olympus later changed the shutter to a ‘Type II’ design to correct the latter problem.

In its standard configuration the OM10 offered aperture priority automatic exposure, simple and accurate enough for a consumer camera in most lighting situations. It also offered exposure compensation for more complicated lighting situations and for more advanced users. A small plug-in manual adaptor was available as an accessory to enable manual control of shutter speed. The manual adaptor is possibly not as easy to use as the typical shutter speed ring around the lens bayonet on the OM-1.

While not well known to consumers, the focusing screen for the OM10 is indeed interchangeable, though not as easily as the OM-1. It shares the same focusing screen as the OM-1, but the extra protruding tab needs to be cut off as the OM10 doesn’t have a placeholder for it.

The OM10 can accept all the lenses of the OM system. 

The finder screen is fixed, as well as the back. It can accept the winder but not the motor drive. It existed in chrome and in black finish.

In 1980 the OM10 Quartz was released with a fixed databack (equivalent of a Recordata Back 3) to print the time or date on your pictures. The OM10 Quartz was only released in black finish.

The OM10 was sold in large quantities before production ceased in 1987 and many working examples are still being used today. Largely overlooked in favor of its more professional ‘single digit’ siblings, you can easily pick up a working example for $50. Try to find one that includes the manual adaptor though, as this accessory alone can fetch $30 at auction.

Assessment:

In a perfect world this camera would just need a clean. But this is me and to be honest I’d like a little bit more of a challenge, as a lot of the cameras I have worked with lately did not need a lot of maintenance because they’d been well looked after. This one may be different.

These cameras were renowned for electrical faults especially with their mirror motion magnets, very similar to the issues suffered on Canons earlier EOS cameras such as the 1N. But to be honest I am just surmising at this point as the camera is not yet in my hands. I need to be patient and await its arrival.

Well, it’s arrived so let’s have a look and see what’s good, what’s bad and what’s indifferent. It has dirt, yes, quite a bit of it, so it will require quite a deep clean as we need to get into all those little crevices, where the dust has settled.

Cosmetically it looks really good with no dinks, dents or scratches, so that is very much a positive. It’s in not too bad a shape for being 46 years old.

The capstan to open the camera film door, along with the operation dial are a little loose, so they will require tightening.

Batteries are long dead, this camera requires two LR44 button batteries to do even the basics, I have tested the batteries with a multimeter and they are so low that they hardly register, they are very dead indeed. The good thing however is that they have not leaked in anyway and the battery chamber is clear of corrosion.

The mirror is stuck in the halfway position, this could be purely to do with there being no battery in the camera. It would be good to see with new batteries installed, if the mirror magnets would then kick in, and then they’d be no further issue. However, knowing my luck they are probably inoperable as well, we will just have to wait. And for this same reason the winder is also stuck, again the batteries may well solve this problem 🤞

Good news is though that the mirror and curtain are in really good condition, because the old lens has been kept in place preventing any contamination getting into that area.

However the lens, does appear to have fungus in it, and will require a clean at some point along the way.

There are also a number of light seals that need replacing as they have perished.

To be quite honest, the easiest part of this camera to clean will be the standard plastic and rubber neck strap. This can just go in some warm soapy water to rejuvenate it. However, my first priority will be to get some batteries in place and see what occurs. I may have to rethink my approach to this camera dependent on the outcome of this simple action.

Repair:

Straight home and I’ve found a couple of LR44 batteries that had a little more power than the old ones. In they go….and nothing. There is a check position on the main dial that should light up and a buzzer should sound to confirm that there is sufficient power, obviously there isn’t in this case. I run all the other LR44 batteries I have through a tester ( I had a packet of 12 ) and they all show as low power, they’ve died during storage. I then pop over the road to see my brother in law who always has a good supply of batteries and bingo, he has a couple of spare LR44s.

With these in place I get an intermittent buzz and a light, it appears the capstan control and operation dial that I mentioned earlier was loose, and has intermittent contact issues, it will need removing and cleaning then reseating.

If I hold the capstan in place I do get a good signal, with both buzzer and light operating in the check position, and when I move the control to “On” position I can now cock the shutter lever. It will then fire but again only to the half way position as it did earlier. If I gently push the mirror down and let it spring back it will then fire. But you have to do this on every stroke of priming the advance lever. Not good.

This is pointing towards an issue with the magnets and I believe I’m almost there, and that’s when I have a eureka moment.

In the bottom of the mirror and curtain bay on the base of the camera is where the mirror magnets are situated, along with a light sensor that takes a reading off the shutter curtain behind, that is checkerboard coloured. Something here didn’t look quite right for me as it did not look level, the base seemed quite uneven. I just simply put my finger in here, applied some light pressure on this base and it just clicked into position, nice and level and then the stuck mirror fired, just like that. Every single prime of the shutter and actuation since, has worked just perfectly, I wonder if this camera has been dropped at some time just knocking this part out of true configuration? Or has someone been here before me? I’m going to have to remove the base to check a few things anyway, so I can then make sure this issue doesn’t happen again. For now, I’m satisfied that the shutter and winder are working fine. I just need to make the contacts and the electrical continuity a little bit more reliable.

I’ve dismantled the faulty switch. Inside, the old tracks on the camera and the pickups on the switch were showing signs of tarnish so I used some contact cleaner go get these looking better. I’ve re assembled the switch and used a new circlip to hold it all together. It’s a lot more secure and responsive now with no interruption to the check signal. It’s quite solid as it always should be.

Here’s a small video regarding the switch repair.

With the switch sorted I’ve now removed the focus screen to give that a bit of a clean.

And after this I have gradually started to remove the old light seals in preparation for their replacement. They really are in quite a bad way and creating a lot of dust and dirt as they degrade.

Now to get the remainder of the old seals removed, clean the troughs they sat in, and then put the new seals in place.

I’ve replaced all the seals on the camera body apart from the mirror damper. I need to get some adhesive first, to secure the plastic plate that sits above the damper. Hence I have to wait for this to be in place before I can finally put the damper in situ, i will do this in the next 24hrs.

Now, the plastic piece that covers the focussing screen access is now secured in place and the mirror damper has been installed, all light proofing has now been completed.

The original lens that was suffering with fungus has been dismantled and given a clean, however because the top two optics are a sealed assembly, guess what? The fungus is within the sealed section and is unable to be accessed. Therefore the lens will never be cured of this issue, it has been improved by cleaning the other optics but it’s not in anyway good enough to use with film in the camera, I will therefore use the old lens purely for testing purposes, it works fine for that and will be just fine for testing other Olympus equipment. In the meantime I have purchased two further OM 50mm std lenses, one is an earlier “Silver nose” model with a single lens protective coating whilst the other is a later production “Black” MC (Multi coated) model. Both are in an excellent clean condition conducive for film photography.

I’m happy that the repairs have now been completed, all that is left now to do, is to give the unit a thorough clean, and to clean that original plastic/rubber camera strap with some warm water.

Result:

Here we present a fully cleaned and maintained Olympus OM10 35mm SLR camera from the 1980s looking quite resplendent after all the work on it has been completed.

It’s been a lovely camera to work on. The make of this camera is superb, and back in the 80s Olympus were on a high note with the high end advertising, using many well known celebrities, and their cameras as a result became extremely popular. They are very well made and have stood the test of time. This one camera will go on to continue being used, and has many good years of life ahead of it. Another one saved from the scrap heap. As with all my cameras I have an immense backlog of units all awaiting the time when they have a roll of film run through them, and this one is no different. When I do pass a test roll through it I will post a link to the results here.

As always, thank you for passing by and glimpsing this post. It is always very much appreciated.
