Digital Cameras
« on: September 29, 2007, 07:22:30 PM »

I have noticed that my digital camera seems to be losing a little sharpness and clarity recently. (A Canon S50). If you can spare the time to troll back through my earlier pics it seems evident to me that a degree of sharpness has been lost. Do digital cameras suffer from a form of electronic degradation? The camera, although well used, is only about 4 years old. I appreciate that battery power can affect a picture. My "film" Pentax lasted for many years without a hitch. Is this a "built-in" problem with Digital cameras? BY.

Make sure you have got a clean lens. if not, they can loose pixel definition or however it is spelt over time. So I have heard anyway. :P

As far as the camera industry is concerned I suspect that 4 years is regarded as quite old.  :(  When my daughter rang the manufacturer of my last camera, which was just about 2 years old, to enquire about an additional lens she was told that they didn't support a camera 'that old'.  :o

I have since upgrade my camera, but my son has the old one which still works perfectly.


I believe they call it built in obsolesence - bit like me really  ;D

I am not aware of any form of degredation that can affect a digital camera over time unless, as has already been mentioned, there is a cleaning issue.

An S50 should only be affected by dirt/moisture etc on the outside of the lens so a good inspection and a good clean may well be the order of the day.  I use computer screen wipes for a lot of cleaning purposes but warm soapy water on a well wrung out cloth will be just as effective.  Another good cleaning tip is to use one of the micro-fibre cloths.  They are very efective.

Hi, check if you have a low pass filter, this prevents dust and dirt gtting onto your camera's picture element and causing fuzzyness and distortion. There may be a way your camera will self clean the element. I have a Nikon D-80 and it will self clean up to a point..Just a word of warning..DO NOT manually clean the element, you WILL damage it, take it to a Canon agent and get them to clean it, It should not cost the earth. I have come across a few digital cameras with this loss of sharpness and it is invariably down to the picture element being dusty....Hope this is some use O0 O0.....Smudge

The Canon S50 is a compact, you can't gain access to the camera or the sensor so if somehow that has become dirty then it will have to be sent away.  I don't think any camera of this type has a self cleaning capability bit I suspect the lens may be worth looking at.

as these compacts are usually sealed, save for the battery compartment, a screen wipe or baby wipe, (same thing only cheaper from tesco), will do the job, thats ALL my camera had

Problem with some baby wipes is that they have lanolin on them ,or some type of moisturiser same as a lot of tissues so your nose is not rubbed on a course tissues as they are becoming,  normal tissues will scratch as well ( even good ones) you need to get a lint free cloth designed for lenses and cleaning fluid that will not take coating of.

Not strictly related only to digital cameras, but for many years I have always fitted mine (SLR, digital and video) with a "neutral" UV filter from new. This protects the lens, is easy to clean and, in the event of damage, cheap to replace.

When was the last time you bought a filter....20p??   But I agree with your principle, better to save a valuable lens for the sake of a few quid.....Smudge

The S50 is a compact camera, you can't fit a filter to it.
