cleaning sensor and focussing screen on DS
My biggest worry is that I might scratch the sensor.

My opinion is don't clean the sensor unless you really have to. Over one year on neither Sue or myself have any need to clean the sensors on our *istDS bodies.

sensor cleaning... well as i understand it no-one actually is cleaning the sensor - what you actually clean is a piece of glass that protects the sensor. So i thought i'd do a bit of a test, i got a piece of glass (old filter) and a piece of plastic (that should have far less scratch resista...

Interesting topic. Here’s my 2 cents worth. I am a subscriber to Luminous Landscape's Video Journal (a quarterly DVD photographic magazine) and in the latest issue - #14, there is a tour of the Phase One medium format digital back assembly lab in Copenhagen. At one point it shows a woman preparin...

Not such a daft question. The rocket blower takes in air through a one-way valve at the opposite end to the blower nozzle. The blower nozzle also has a one way valve to prevent dust ingress. Just out of interest, I bought a small bottle of Eclipse cleaning fluid containing 59ml of methanol. As I'...

Peter, If you want to try out a cleaning fluid - try it on a "Pro" filter. They're pretty tough and will show up any streaking problems (or the like). Matt

Not such a daft question. The rocket blower takes in air through a one-way valve at the opposite end to the blower nozzle. The blower nozzle also has a one way valve to prevent dust ingress. I wasn't very clear on that but my actual point was, how clean is the air going into it that you are blow...

Hi Drew, it'll pretty much be as clean as the surrounding air. Wrap a piece of a coffee machine filter or similar around the exit tube, and see what you catch. You'll probably lose a fair amount of the power though, as the "filter" will diffuse the air, depending on how the fibres of...

Hi Drew, it'll pretty much be as clean as the surrounding air. Yes, that was what I was trying to point out (in my own no so "daft" way :lol: :lol:). The world is a very dusty place and the air I am cleaning it with is probably as dirty as the air that got it dirty in the first plac...

:shock: so i take it that using say a kenro or simular compressed air duster is not a good plan then (not had to clean a ccd yet) you could also safe gaurd against dust by changing lenses in a more dust free enviroment ie turn your back on a race track and change with your camera inside a coat in...

It's worth a mention perhaps that the sensor is usually covered anyway, by the shutter! (Or should it be called the "opener"?) I know this is not hermetically sealed, otherwise every exposure would cause dreadful vacuum problems, but it is a cover and the risk of contamination is signi...

Dust does get in. Generally it doesn't affect the images, but if you try this you'll find out just how much dust you have (or haven't): * Point the camera to a cloudless piece of sky (if you can find some :D) * Put to manual focus and set to a close focus point * Set the camera to f/22 (or sma...

:lol: another way of preventing dust is to keep your rear lens on your camera lenses clean and dust free then even if you have gadget cases no matter how soft and gentle the interior may be keep your rear lens caps on your lenses correct me if im not wrong but the problem with dust in digita...

Dust!! Let me tell you about dust. No matter how careful you are, try shooting in Malta - a permanent construction site. In the "country-sde" its pure rock and wind and soil.

. Just out of interest, I bought a small bottle of Eclipse cleaning fluid containing 59ml of methanol. As I'm in Spain for a while I had a look round some of the local stores and found a 500ml bottle of pure methanol (without colourant) for €0.60, about £0.40p. Eclipse, needless to say, is ...

Off topic a bit since the OP was talking about a DS, but what do people think about cleaning the sensors on the K100/K10? I know theoretically this shouldn't be needed on the K10 because of DR, but the K100 has no such luxury. I'm not that worried about damage to the CCD, as I think the low pa...
