What the listing stated:

This is a Canon Powershot S5 IS Digital Bridge Camera which is faulty and sold for spares or repair only.

The camera is in excellent cosmetic condition but when switched on there is an error message saying lens error please restart camera (see photo).

It takes 4xAA batteries and SD cards (not supplied)

A little bit about this camera:

Released in June 2007, the PowerShot S5 IS is the successor to the S3 IS model launched in April 2006, which was well received for its optical image stabilization, high zoom ratio and ample movie-shooting capabilities. Like its predecessor, the high-function, high-performance S5 IS features a 12x optical zoom lens equipped with a lens shift image stabilizer and realizes fast, quiet zoom performance by means of a high-speed Ultrasonic Motor (USM).

Compared with its predecessor, the PowerShot S5 IS delivers improved imaging performance through the incorporation of an 8.0-megapixel CCD sensor-increased from 6.0 megapixels in the S3 IS-and an upgrade to Canon’s high-performance DIGIC III image processor from the earlier model’s DIGIC II. Additionally, the S5 IS employs a 2.5-inch high-resolution (approximately 207,000 dots) vari-angle LCD monitor that offers a wide viewing angle to realize a high level of shooting flexibility, and includes a hot shoe for compatibility with Canon EX-series Speedlite flashes.

The new Canon PowerShot model supports the recording of high-quality movies by enabling users to make use of the camera’s optical zoom and Face Detection AF/AE functions. The S5 IS also offers an LP movie mode, which employs a higher rate of image compression to enable longer recording times for VGA movies, as well as high-quality stereo sound, and seamless transitions between the shooting of still images and movie recording.

I’ve been watching this one for a little while, it looks very good cosmetically and I’m surprised as I was the only one that bid on it. I’ve paid a total, including postage of £8:81GBP and I think that is an absolute bargain. An issue with these cameras has always been a motor/lens error. These motors within these cameras are an ultrasonic motor (USM) and to be totally honest they can be quite delicate and are known to give up as such, if even a grain of sand was to get stuck in the lens gear mechanism. They are delicate souls that don’t really like hard work 😂

A good clean is sometimes all that is needed to get these cameras working again, however I’m not going to get ahead of myself here, as I just don’t know what kind of pain the previous owner has inflicted on this camera. I just hope they have not been too brutal.

Assessment:

Now this is an absolutely beautiful looking little camera in pristine cosmetic condition. The previous owner has in fact been extremely careful and treated this camera very well.

The only issue that I can see is the one that flashes up on the screen, continuously when to turn on the camera. Even moving the telephoto/wide switch when starting up does not clear the fault. I really need to get the lens extended to see what’s going on. If I can do that without getting the screwdriver involved then that is even better.

Repair:

The lens remains stuck in the closed position despite there being movement with the lens iris, all other actions are as expected, just no extension of the lens turret. It does sound as if something is trying to move inside.

I’ve tried resetting and going back to factory defaults with no joy. I have been noticing though that when i put in a time and date, it is resetting every time i turn the camera off and then back on again. This is usually a sign that the small internal memory battery is dead, and as it’s probably been in the camera since 2007 it’s probably a good idea to change it. If I can find it. That is.

Panic over I have found the memory battery (CMOS) it was located in the battery chamber beside the SD card slot. It’s a small CR1220 coin battery and I have one of these in my battery box, so this will be replaced as soon as I get it home, now replaced all is working as it should be.

Back to the error. The error is more often than not caused by something, even a grain of sand getting in the turret area and catching in the workings, as these cameras are so delicate. We have to somehow get into the turret area to see if we can dislodge whatever is causing the problem.

I’d advise against using canned air here, as doing so would most probably dislodge the obstruction, however the route down the turret leads directly to the image sensor and you don’t want debris on that. Careful is the buzz word.

I cut a small strip of paper and feed this down between the tiny gap between the lens and the body. I manoeuvre this around the full circumference of the lens, and as I do I can feel some slight resistance as if something is there. I go around again and that resistance has gone. I turn the camera on and still there is no extension of the turret. At this point I put the mode dial on the camera into video mode and then turn it on. Straight away the turret extends and what looks like some grains of dirt fall from the lens area, at last we have the lens extended and there is an image on the LCD screen.

I clean the lens turret with an optics cloth and you can see it was very dusty inside, there had definitely been some debris enter this area causing the issue.

I operated the on off button a number of times to ensure the turret motion was smooth, and it was. There are no further obstacles in this area, causing the mechanism to seize.

I have taken a number of test photos trying out all modes and features and the camera is just perfect.

I’ll show a few more photos below, once I have been able to download them.

Result:

This camera is simply a little beauty. It is probably one of the best looking of the later generations of bridge cameras but maybe not the best photo quality wise at 8mp. But who cares though, when you are as good looking as this?

The camera is pristine in my eyes, and for just over £8GBP this is a bargain. These fixes do not always involve a total dismantling of the item, sometimes it is so simple it’s unbelievable. Here I used a piece of paper and a lens cloth, that’s all. Now a camera destined for an old box in the loft and then the tip has been saved to carry on taking photos for a good few years yet. In fact here are a few photos that I have taken randomly around work, and around my garden.

I’m probably going to use this camera with its pivoting screen to construct videos to display on this site regarding future repairs, I’m going to ensure it gets good usage under my ownership.

Did I tell you how much I love this camera and how handsome it is? Oh, I did, sorry about that, I get really carried away with these older cameras, I just wish everyone else could get as excited as I do, and maybe so many of these wonderful machines wouldn’t then, just get thrown out with the bath water.

Thanks for passing by. It’s always most appreciated.
