I like these little point and shoots. I’ve always wanted one, and ideally I would like an original 35, but in the meantime I’ll settle for this one. Not working, only £17:00GBP, this was a bargain price for an old camera with a lens that has a superb reputation for having good optics. It’s a bargain basement price for a camera that has a lot of potential if I can get it working again. I have purchased from this supplier before and they are a good bunch of guys and girls, so I don’t believe I am being ripped off in any way. This camera dates from from around 1974.

Here’s a little bit about this camera:

The Rollei XF35 is a small 35mm full frame Rangefinder camera released by Rollei in 1974. The same camera can be rarely found under the brand Voigtlander: in this case it’s called VF135. 

This camera provides only a programmed exposition, with a CDS cell powered by a small 1,35v PX 625 mercury battery. A ring around the lens must be set to the right ASA/DIN value.

The shutter is a small Copal central type one, that also works on relative aperture.

The lens is a Carl Zeiss Sonnar-derivation, built under license by Rollei. It’s a 40mm f2.3, with focus from 1 meter of distance. The viewfinder has a small frame that indicates the f-stop and the speed of the shutter that the program will use. At the center, two small yellow and red circles must overly to obtain focus on the subject.

Shutter speeds go from 1/30 to 1/650s, including bulb mode (only at f2.3). Copal shutter closes up to f16, so Rollei reccomends max 400 ISO/ASA films.

There’s a hot-shoe flash slot and the camera also includes a self-timer (circa 10s of delay). Under bulb mode, this timer can fire the shutter to a speed of circa 5 seconds.

I’m expecting the camera shortly, so in the meantime I’m off to read the manual and to also look for replacement batteries that replace the now defunct PX625 batteries this camera used to have to maintain a sufficient power supply. When it arrives we can carry out a full assessment.

Assessment:

On arrival it’s a nice tidy little camera, with slight signs of use and that slight mustiness of being in storage for a few years, though I have smelt worse.

It needs a little clean, the strap buckle is a little rusted however that is easily replaced.

Inside, the camera is clean, the winder works and the exposure button works, however the shutter doesn’t fire. This could be one of a couple of issues, the battery inside that appears to be an original PX625 Mercury battery could be below power, and if it is an original this could well be the case. However the light meter is working and this is a welcome bonus, so there is a little life still in the battery that should be 1.35v when at full power.

Let’s check this with the multimeter, before purchasing a new battery, and I can confirm the battery power sits at 1.53v?

I was mistaken, it’s not an original PX625 it’s actually a 625A alkaline replacement. These alkaline batteries are 1.5v rated against the original that was 1.35v. These batteries are commonly used with these older cameras as a suitable alternative to the original battery. The only issues that are sometimes reported are that the metering can sometimes be off by about +2stops, however some people report no issues at all so it is all a little bit and miss to be honest. I guess it’s all down to trial and error with your own film stock and the camera, B&W film would probably be more forgiving. So, in this case it is not a power issue. We need to then move on to another option.

The other related issue could be sticky blades on the shutter mechanism, and that is more than possible if the camera hasn’t been used in quite a while, the old lubricants dry out over time and the shutter blades get stuck, this means I would have to carry out a service of the shutter mechanism, not a major issue just quite time consuming.

Repair:

I have liberally coated the shutter blades from inside with some isopropyl alcohol as that’s all I had available at the time. This has removed some old black gunk that appears to be old oils of some kind, however the shutter still does not operate when activated, even though all the noises are there to suggest the mechanism is actually working.

I have used a compatible tool to tempt the shutter blades open, this initially worked but they did not fall back into place with any urgency. I suspect there is residue on the opposite side of the shutter blades, so it looks as if this will have to be a full CLA – Clean, lubricate and adjust, requiring a partial disassembly of the camera.

Boy I wasn’t wrong, this is probably the deepest I have gone into a camera for quite a while, this camera really does have to be dismantled. These cameras have always been renowned for having issues deep into the cameras workings, it’s probably what has gained them a poor reputation, somewhat unfairly, but not everyone is prepared to dismantle a camera at these prices, when they can just chuck it and get a new one. However that’s not what I do here.

Let’s stop the chat and get on with it.

So we need to get inside, and the best plan of attack is from the front through the lens turret, so first thing we do is remove a retaining ring on the lens. This allows us access to the insert that controls the ASA, and where the CDS cell is located. Remove with caution as there are small wires present.

Three screws under the ASA/CDS module then allow you to remove the focus ring where there is a small brass plate. This is removed and then the rest of the barrel loosens, but cannot be removed….strange.

At this point I had to do a little research and source the maintenance manual and refer to it to see what I had to do next.

After reviewing the manual it appears there are another four screws requiring removal before we can access any deeper, however these are situated under the camera “Skin” and this needs to be peeled back slightly to access.

With these four screws removed, you now have to remove both the top and bottom parts of the camera, five more screws to allow the front plate and lens to be removed.

With the lens plate now movable, again I carefully move it aside being wary that there are also wires here, and not a lot of room for manoeuvring. A slight twist of the brass aperture control plate and it can then be removed. The plate below this, with the three brass dots, just clips out and exposes the thin shutter blades below.

Just looking at the shutter blades I can see there is a small link missing, this was sitting loosely to one side, it could have come off as I was dismantling the blades, who knows. Carefully put to one side the blades are placed individually in preparation for a clean. Lastly the bottom plate of the shutter mechanism, lifts out and beyond this point is the camera back, we have just a hole as the whole shutter and lens mechanism has now been removed.

All parts removed have now been cleaned with an IPA solution to remove any grease and dirt, and there was quite a lot of both. These have all been put to one side and will be cleaned once more prior to reassembly.

A period of time was spent just watching and observing whilst I continued to prime the camera and fire the mechanism to see if I could see anything obvious that was of concern. After a while I could see the issue, there is a small flywheel that was not moving, and as a result the connected shutter mechanism could not move.

The flywheel controls two parts of this mechanism. Firstly the shutter mechanism to move and work the shutter blades, and secondly there is a small brass pin at the top that also moves relative to the aperture setting, if this is in the wrong position, the shutter fires but will not close, this wheel is where the issue lies.

Using some IPA I get into the gearing from the base area, and give all the gears that I can access a good clean, I activate the camera numerous times to get as much grease and dirt away from the workings as possible.

Then using a very fine camera oil, very sparingly, literally a drop on top of a needle applicator, I place oil onto the cogs paying special attention to the offending fly wheel.

I have three shutter blades that are super thin and delicate that need a final clean, dry and a dry wipe prior to reinstalling. I get this done and then put both links in place, after installing the blades in the correct order.

The re installation of all other parts is just a reverse action of how they were taken out, each part was cleaned as it was put back, so in theory the camera is an awful lot cleaner and free of contamination than it was a while ago. Before I put the lens plate back on the camera I check the shutter’s operation and it is all fine. Just a final calibration of the aperture settings, a check of the focus range, and just ensuring all wires are routed sufficiently, and the lens plate is ready to attach to the rest of the camera. This done, the base and top fascia plates are attached after first cleaning the focus window and light meter window. The camera is now fully assembled, it now just needs the camera “Skin” to be re glued where it was earlier removed for access.

The skin is now glued into place.

Now I’m outside the camera I’m just going to touch up some of the scuffed areas with some permanent marker, it’s not worth stripping down, priming and repainting, to be honest I’m quite happy just doing a touch up of the scuffed areas and that is what I have done. Once it gets a clean and polish it will appear much improved, compared to when the pen is first applied, it will blend in.

I’ve taken the old strap buckle off as that was rusted, I’ve just used the original strap ring to connect to the camera lug, I think it looks good. I’ve also added a cover for the hot shoe connector that I’ve printed off on the 3D printer.

And that completes the repair, the last thing to do is get this camera cleaned and polished.

Result:

With a good clean and polish, this little handheld has come up looking superb.

With all the extra touches, we now have a superb working, resurrected camera that was heading for landfill. This has taken a lot of time and patience, something I don’t have a great deal of if I’m honest, but I was determined to get this project finished. And it is. It looks good, works good and has years of life left in it. Currently sitting at 52 years old, it has a long life ahead of it.

This camera probably rates as one of the most fulfilling and pleasing projects I have ever started upon and completed. It’s been a very delicate and time consuming job, and that I will not deny. It’s only a cheap low cost camera but it’s taught me a great deal. It’s the first complex project I have undertaken, in my new workspace, I don’t think I would have been able to complete it with my old set up. It’s been an achievement, one I am considerably proud of, an occasion when once again, it doesn’t matter how old you are, you can still learn a lot. A big positive for me.

Anyway, enough about me.

Thank you most sincerely for passing by and giving me your time. It really is, very much appreciated.
