Olympus OM10

Always liked and wanted an Olympus OM10. 46 years later I now have one. Of course, it needed repair.

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.

Nice camera, few dinks and dents, and a lot of dirt

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.

Viewfinder looks clear apart from a little dust build up

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.

We have the check light, and a little buzz…intermittently

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.

Switch working as it should

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

Focus screen removal, cleaning and replacement

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.

With some IPA, and a large bamboo stick it’s time to remove the old seals

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.

The two new lenses – “Silver nose” to the right

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.

Canon AV1

I now have a Canon AV1 with a shutter problem. Can I fix it? I’ll have a good go…

What the listing stated:

This camera is in very good overall condition. Some light signs of use but this is generally minor. The light meter is responsive when you press the shutter button down. However, the shutter will not fire. Spares or repairs only.

EBay

I’ve just paid £8:98GBP for this camera, and I believe this is a great price for a piece of camera history. The AV was introduced due to there being a demand for aperture priority at the time, whereas its Sibling, the AE1 was purely shutter priority. Later cameras would come to incorporate both systems. This one has a known problem with a stuck mirror – it won’t fire and I think I can easily sort this problem. Well I hope I can.

Here’s a little information about this camera:

The Canon AV-1 is a 35 mm single-lens reflex camera with an FD lens mount, introduced by Canon Inc. in 1979.

The AV-1 is very similar to the 1976 AE-1 but provides aperture priority autoexposure rather than the AE-1’s shutter speed priority AE.The camera is not capable of fully manual exposure. Canon’s international distributors, particularly in the United States, had clamored for such a camera because competing brands offered mostly aperture-priority cameras and some preferred it. The AV in the name referred to the type of autoexposure; Av (Aperture Value) is a common abbreviation for aperture priority.

When this camera appeared, a new range of FD lenses was introduced, with instant mounting/unmounting of the lens. This is called the New FD mount and does away with the older type of mounting ring which was fitted on to the rear of the lens and was awkward to use and needed two hands, to a newer, easier system whereby the user lined up the red dot on the lens, with the red dot on the camera and simply turned the whole lens clockwise until it clicked into place.

All the other AE-1 accessories fit the AV-1.

Wikipedia

I’ve decided to collect all of the Canon “A”Series of cameras, and this adds to my current collection that consists of an A1 and an AE1. There were I believe, six cameras in this range and this current camera will be my fourth. Here’s a list of the “A” range of cameras below. I have highlighted with an asterisk all that I currently have at the date of this blog post being published:

Canon AE-1 (April 1976)^*

Canon AT-1 (December 1976)

Canon A-1 (April 1978)^*

Canon AV-1 (May 1979)^*

Canon AE-1 Program (April 1981)

Canon AL-1 (March 1982) *

Assessment:

The original listing description does not match the issues that I have found. It originally stated that the light meter is responsive, it isn’t. It also stated that the shutter does not fire, it does when a battery is installed. The battery level indicator in the viewfinder does work when the check button on the camera is depressed. However when you focus the camera and half depress the exposure button to get a meter reading, the needle in the viewfinder doesn’t respond, this is the only real issue I can see, I guess the seller must have been looking at another camera as he wrote the listing for this camera.

All settings appear to be working as they should, the “B”setting allows me to scroll through the “f” stop settings to see the aperture leaves working as they should. All “f” stop settings appear to work on the auto setting.

It’s a smart little camera, this a tidy example of this version with no dents, dinks and just some very fine scrapes on the base as you’d expect from a camera fast approaching 46 years old (1979-2025). It’s a bit dirty and needs a good clean inside and out, the light seals are in a good state and not requiring replacement or repair just yet, however the mirror bumper has deteriorated and this will need replacement.

The shutter curtain is in a good and untouched condition.

I’m going to research issues with the exposure indication, and I will incorporate my findings within the repair section.

Repair:

I thought, perhaps the camera is suffering from lack of use? It certainly is probably some considerable time since this camera was last used. Firstly I’ll try exercising all the controls that affect the exposure reading, including the mode dial, film speed dial, aperture ring, etc. I’ll work them backwards and forwards a few times to see if this helps to clean the variable resistor tracks inside from any surface contamination. When the FD lens is attached you must be mindful that the “A” setting on the lens is not used and that the f stop settings are used in a manual manner, lens auto is not a function on this camera.

To be honest, this did seem to work sort of. The needle has moved off the bottom a bit. The ASA setting was on 100, so I put it up to 1600 as it is quite a dark day and the sensitivity of the light sensor would be reflected better at this setting. It moved a bit but I wasn’t totally convinced that this indication in the viewfinder reflected the true light situation.

There’s also a small, silver push-button just inside the lens mount at about the 4-5 o’clock position. If you press this in and release it a few times for the same reason, as exercising the dials as I did above, it is just like exercising a body part and keeping it supple. Leave items like this, designed for high usage redundant for a while and they soon seize up. it has also been known to assist with getting the needle indication working after a long lay off.

(A little bit of trivia here – this button is normally used for the lens to inform the body of the lens’s maximum aperture. This information isn’t needed on the AV-1, but Canon included it anyway for some reason, and it does affect the exposure.)

And combining these actions, moving the settings dial and the button inside the lens mount seems to have revitalised the light meter and I’m now quite confident that it is working as intended. It was just lazy due to low use and needed a bit of non invasive intervention to get it working again. And non invasive intervention is always a good thing. So with the setting back to 200ASA I was able to show the meter working in this very short and basic video below.

A brief video showing the meter needle moving

I’m confident that the metering issue is now sorted so let’s get that new mirror damper installed.

A lot of dirt came off of the area where the replacement damper had to go, it had completely deteriorated and took quite a bit of cleaning.

Now in place it has silenced the mirror movement somewhat, and will provide some longevity as it moves into the twilight of its years. It will be good for many more rolls of film yet. Whilst in the lens area I have cleaned the mirror and prism, and given the area a good blow through and put the lens back in place to seal it all up. It is now clean internally. I have a couple of body caps on order that will assist with storage when the lens is removed.

Just a final clean with some cockpit cleaner, and this camera has come up lovely, I’ve tested it on a Power winder “A” as well and it sounds just so good and “retro”. It’s perfect.

Result:

Well. I now have another lovely example of one of the Canon “A” range of cameras to add to my collection. This brings my current total to four out of the six available, two of which are still currently under repair. For less than £10:00GBP it is so easy to own a piece of photographic history. I have been lucky here that the work that had to be done was non intrusive, and to be quite honest was just basic everyday maintenance. The only real work of sorts was installing some mirror damper felt, of which I have plenty of stock. Cleaning was quite intensive but the overall result is amazing.

Looking amazing compared to what arrived

I will eventually run a roll of film through for a final quality check, however I have such a backlog it will take me a while. When I do however run that test roll I will post a link here:

Really pleased with this repair, and the fact that another lovely old camera has been saved from the scrap heap and been given a new lease of life.

Thanks as always for passing by. It is as always, very much appreciated.

Werra 1 stripdown and rebuild

I recently purchased this camera and wrote about it in a previous blog entry Werra 1

I’ve commenced taking the Werra to pieces. The winder was not working and the shutter was not firing. Before starting this work I’ve viewed this page at Everything Vintage where they have recently carried out a full strip down of the Werra and you can view the page HERE, it’s all great advice.

Getting below the top plate was relatively easy exposing the mechanics from 58 years ago, I don’t think it’s ever been opened in all this time. I always love to see the ingenuity that went into these old cameras in years gone by.

The internals look dirty in the photo but to be truthful I don’t think the lighting is doing it any justice, yep there is a fine oxidation coating but it’s at a very acceptable level considering its age. When I get to the point of dismantling as much as I can, I will start to clean and lubricate these pieces. But at the moment my goal is getting to the shutter.

Werra winding system – shutter not working

In the video above I’ve managed to get the shutter cocking using the lens ring, however the shutter actuator does work intermittently, but there is no movement of the shutter (Or is there…)

The only reason I ask the question above is that after reading the “Everything Vintage” link in the first paragraph it appears there is a second shutter that closes the light path to the film back when you wind on. When you are ready to expose the film this shutter opens and then there is a second shutter that controls the exposure. if you watch the small video above I think it is this shutter you can hear when I wind the camera on. Hopefully this one is working, I just need to get the one on the rear working, and for this I need to remove the lens from the housing. To do this I need a tool I don’t currently have but have now ordered. More to follow when the lens ring removal tool arrives.

The lens ring spanner has arrived, the ring is being right stubborn at the moment and Im struggling to release it from its 58 years of rigidity. I’m tired as well and don’t want to cause any damage to the shutter so I’ll come back to this later.

18 hrs later, I’m rested and have another go at releasing that lens ring, this time I’m successful and I manage to release it. Sometimes it’s better to sleep on a problem and approach it with fresh eyes rather than continuing whilst tired and prone to making mistakes.

With the lens off the body, the shutter cassette can now be removed. It amazes me just how intricate this cassette is and the workmanship that must have gone into it. I’d estimate at least 10 small cogs and a number of tiny springs with levers and pivot points, amazing really considering it’s about 60 years old. It’s amazing how modern technology has advanced.

It takes some time getting into the shutter cassette as there are springs and things flying off everywhere, you really do have to photograph everything you do just to be able to check what goes where and how.

Inside mechanism – where is that spring from?

The shutter itself is rather clean apart from some fingerprints on the shutter leaves that must have been from years ago. I have cleaned this down with IPA and then used some finely ground carbon (pencil lead) as a dry lubricant and this has got the shutter moving just fine.

Werra shutter after being lubricated with carbon

I’m now starting to reassemble the lens and shutter as I’m happy that there is nothing else restricting the shutter and it is now moving quite freely. I will clean the camera as I progress and put some watch lubricant on the mechanics that are external to the lens and shutter assembly.

Well it’s all been reassembled and is now back in one piece. It looks good, the shutter works fine and I’ve now vacuum packed it to go back into storage. I won’t be firing up a roll of film on it yet as I don’t have the time to did so at the moment. I’ll probably save that until the summertime when the weather is more favourable. I’ve really enjoyed this restoration even though at times it was very frustrating. This rebuild has taught me patience, or at least that I need to have more patience and just take my time. Intricate jobs on such old equipment need a clear head and a lot of concentration. I’ve learned my lesson and will endeavour to remedy that situation in my future dealings with such equipment.

Halina A1 Reflex shutter and Fungus

Managed to get the shutter firing after a while of blasting with compressed air and constantly cocking and firing the mechanism until it clicked into life. Probably stiff due to not being used for a number of years and left in storage. When I get the unit apart I will help it along with a little clock oil.

When shining a light through the back of the camera with the shutter open the fungus issue on the lens is most apparent, this is a three part lens I believe so it’s going to take some time and patience to achieve, but it’s do able, but it will have to wait a while.

Shine a light for all to see…..fungus

So I’ll leave you with this for today, the smell of years of dampness invades when ever I get this camera out of its box and to be honest I think that will be my biggest challenge with this unit. Any ideas and tips on how to assist with this problem gratefully accepted 👍
