Minolta 110 zoom Mk1 SLR

The world’s first SLR 110 format film camera. A strange creation that has its issues, from 1976-79. Can it be resurrected and put back to use?

What the listing stated:

The Untested MK1 1970s Minolta 110 Zoom SLR is a vintage film camera that comes with a case and strap, making it easy to transport and store. This compact camera from Minolta features manual focus and is designed for 110 film in a 13x17mm format. The black-coloured body gives it a classic and timeless look, perfect for film photography enthusiasts looking to experiment with older technology.

With its retro charm and unique capabilities, this Minolta 110 Zoom SLR offers a glimpse into the photographic world of the 1970s. Untested

Yes you did read right, this is a 110 format camera with SLR. Now, I have had this camera sitting amongst my backlog for a few months now, it was purchased towards the end of 2025. I believe I paid the sum of £14:00GBP for it, and considering current prices on the sales sites it’s quite the bargain I think.

The reason I’m looking at this one is because I have been approached by someone to repair their one, now before I look at their issue (a stuck mirror) that seems to be a standard issue with this model, I want to look at my own one that I believe may well have the same issue. It’s best to learn how to deal with the issue on your own unit, before being let loose on someone else’s.

However, saying that, the listing was a little vague with only the standard “Untested” EBay catch all quote meaning it could be anything between a total wreck, to working perfectly.

Here’s some information regarding this camera:

The Minolta 110 Zoom SLR is a 110 format single-lens reflex (SLR) camera produced by Minolta of Japan between 1976 and 1979. It was the first SLR in 110 format. It has an unusual, flattened shape. Other 110 SLRs were shaped like SLRs in larger formats, but the 110 Zoom SLR took the flat format of the typical 110 pocket camera and added a larger lens and prism hump to it. 1979’s replacement, the Minolta 110 Zoom SLR Mark II, has a more conventional shape.

The 110 Zoom SLR provides aperture priority autoexposure; fully manual exposure is not available. Light metering is with a CdS meter mounted on the front of the camera. An exposure compensation dial allows the photographer to compensate for unusual lighting situations; it also allows the use of film speeds other than the ISO 100 and 400 auto-selected by the cartridge tab, by applying the appropriate compensation factor.

The lens is a fixed 25–50 mm f/4.5-16 manual focus zoom with macro focusing down to 11 in (280 mm). This gives a field of view range approximately equivalent to a 50–100 mm zoom lens on a 35 mmformat camera. There is a built-in, pop out lens shade. The filter thread diameter is 40.5 mm. Minolta sold UV, yellow and 1B filters.

Available shutter speeds are 1/1000 second through 10 seconds, with a 1/150 second X-sync speed and support for bulb exposure. There is no built-in flash, but a hot shoe on the top allows an external flash to be attached. A tripod socket is provided.

Let’s get the assessment out of the way.

Assessment:

The camera has arrived. And the most annoying thing about it, is that it appears to be working just fine. I have been through every possible combination of settings available, hoping to get the mirror to stick up (as is common with these cameras) but to no avail. Everything appears to be working just fine. Damn that’s annoying as the “untested” EBay get out clause used so often by questionable sellers, has on this occasion gone in my favour. If you refer to the opening paragraphs, you will see I wanted to work on this one to diagnose an issue that a potential customer has asked me about. I may well just send him this working one in exchange for his knackered one, how’s that for service!

Anyway, here is what I received, in a black Minolta case, it has been well looked after and is just a bit dirty and in need of a clean.

All in a good, just dirty/dusty condition

Lovers of lomography really rate these cameras, the 110 film cartridge is quite an expensive outlay these days and from what I can see with film costing about £9:00GBP for a roll and then about £18:00GBP for developing and scans only, you are looking at quite an outlay of almost £30:00GBP for the results. I don’t think I will be attempting this unless I come across a less expensive option, as I’m sure there will be one out there….somewhere.

So, with not much more to tell, let’s move on to getting it repaired….or should that be cleaned?

Repair:

Closer inspection of the lens when I’m cleaning shows me that there is a small area on the outer optic of the lens that has a solitary spore of fungus. It’s nothing too much, however a quick clean of the exterior of the optic, confirms the issue is inside. I’ve now got to dismantle the lens barrel to get to it.

The fungus is on the rear, not the front of the outer optic.

The bad news is that on close inspection and using a soft plastic pick, a tiny indentation at the point of the fungus can be felt, this shows that the fungus has eaten into the optic coating and no amount of cleaning will ever eradicate it. Two options here are a new optic, or to get the optic ground down, both totally beyond the value of the camera and to be honest totally unnecessary. The good news is that there is no fungus on the inner optics, and luckily this needs no cleaning or attention.

To be totally honest, the negatives in these cameras are so small, and the outer lens magnification is probably sufficient enough to make this aberration appear as nothing more than a slight blur, if it even shows up at all! I’ll give it a good clean to prevent any further growth, and just put it back together again. There is a good possibility that a film will never be run through this camera again, even so I would like it to look as good as possible, and operate as it should, if there is even the remotest chance of a film being used in it, sometime in the distant future.

Result:

The camera has been reassembled and is looking quite nice. It’s a really weird camera. So weird that someone has offered to take it off my hands, as they believe it’s quite a novel item, so as soon as I’ve posted this report it will be winging its way to its new owner.

It’s probably best that I pass this on to someone who will either use it, or at least make a use of it should it become a display item.

A nice little camera, but to be honest it’s more than likely more of a display piece rather than a working camera. It is fully operational though and has been nice to work on. I’m pleased someone else will eventually benefit from it.

Thanks for passing by, always appreciated.

Sometimes, but very rarely, “AI” may just work in your favour.

I’m fixing this lens and came across this broken part. But what is it called? Does Chat GPT know the answer? It seems it does.

Please do not for one minute consider this an endorsement for AI, it’s not. I very rarely ever use it, and to be totally honest I keep as far away from it, as i possibly can. The only issue is, is that it gradually sneaks through the back door unannounced in pretty much any application or program that you now use. There is no escaping it really, even here on WP this week I received an invite to start using AI to write my posts and to control their content and SEO compatibility, whatever that is. Straight in the bin it went, no thanks, not interested.

I know my grammar and punctuation leaves a lot to be desired, and sometimes it is very poor, but hey! That’s me and I don’t want to suddenly appear to be a fully functioning and academic genius, as that’s just not me. I’m a Comprehensive educated drop out, that has managed ok thank you, and I don’t need some computer to portray me as something I’m not, or am likely never going to be.

Rant aside, let’s get back to the story that is based around the item in this picture.

I’m currently carrying out a repair on a Canon EF 28-200 lens from around the year 2000. Whilst dismantling this lens, the above part became the item of interest as this is a piece that controls the zoom of the lens, hence this lens never really worked due to it’s inability to focus or zoom, and the item above appears to be the guilty party.

It’s broken, that is clearly obvious to see, it’s made of an alloy, possibly aluminium, and is not repairable by soldering due to the immense high temperatures that would be required. I can’t achieve such temperatures as I don’t have the equipment available to do such work. I could try forming something from scratch, that is an option but I don’t really have the time or patience to be honest to spend such time on such a tiny piece of metal. The whole piece is no bigger than 2cms long at its longest point. It really is tiny but essential for the smooth operation of this lens.

This is where the AI help comes in.

Having looked at many repair manuals belonging to Canon, I have an immense list of code numbers but nothing at all explaining what this item is or if there are any still available. I’m kind of lost and at odds as to what I should do.

In desperation, I type something similar to this request into Chat GPT:

“Long angular aluminium piece, working the telephoto element of a Canon EF 28-200 lens”

And this came back as an option:

Bingo – Courtest of Barrell Y Store – Ali express

Wow. That looks familiar!

And it is in-fact the part I am looking for, on the Ali Express site, our friends in China have one left in stock – “Click” that’s purchased and is now on its way to me.

I am now also fully aware of what it actually is, apparently it is called a “Zoom guide pillar, zoom lever, electric brush lever for a Canon 28-200 zoom lens”

Well there you go, it appears AI is good at deciphering the ramblings of a frustrated and confused 60 something. And in this case it did very well. When this arrives I’m going to give it to one of the tool makers at work to get him to make a few copies, I’m even going to see if I can get a few printed out 3D wise to see how the plastic version holds out under the demands of the lens. I don’t foresee any real issues as long as the lens isn’t mistreated in any way.

Well. That’s my major frustration of the week, and my first real face to face involvement with AI.

It can only get better, or can it?

Have a super day. Stay real.

Canon EF lens 35-80mm

As the listing stated:

Needs opening cleaning and fixing sounds like something loose so selling as a repair project cheap.
EBay

No error code so in theory this should be an easier fix, however the fact that something is moving about inside tells me there could be more wrong with it than expected.

I now have the lens in front of me so here is what I can see.

Shake rattle and roll

Well, it certainly does rattle, something quite significant is moving about inside. When Connected to a camera you can’t focus or zoom so something in there is restricting movement. There is also fungus on the lens so this one will need to be carefully dismantled and cleaned throughout.

About 10 small screws later I am into the internal parts of the lens and the cause of all the rattling becomes apparent. A piece of the internal zoom mechanism has broken off stopping the zoom from smoothly operating through its range.

The part of the barrel that the item had snapped off was broken due to forceful action with the previous owner. There are two options here, junk the lens or see if it can be saved, I went for the latter. I mixed some epoxy resin and fixed the piece back into place also gluing it to a part of the mechanism that was not liable to hinder future movements. I left this for a couple of hours to cure.

Whilst waiting for the glue to cure I used a mixture of water and hydrogen peroxide to clean all the lens elements. I thoroughly dried them and gave a quick polish and reassembled them into the casing. The glue was dry now so I was careful to reassemble the lens not damaging any ribbon cables or contacts along the way. The lens looks lovely and clear of any fungus now.

I’ve put the lens onto a test camera and it’s fantastic. I couldn’t get focus when I unpacked the lens but now I have the full range of action and a lovely clean working lens for very little outlay and probably just 2 to 3 hrs of maintenance. Well worth it in my opinion. I wanted a good cheap lens to test my old stock and I now have one that I can easily sell on at some point, on top of that I’ve learnt a lot from working on one of these lenses. I’m certainly going to attempt working on more in the future.

Thanks for passing by. Always appreciated.
