1Ds sensor cleaning - try this

JasperF · Mar 22, 2003

there are different manufacturer, do a google search on cleaning tissue for microscope lenses
http://www.2spi.com/catalog/supp/05178-80.shtml

this is one manufacturere. also cleaning fluid for microscope lenses. since some of the cleaning fluid will make the seal to come off on some parts.

the tissues for microscopes are usaually lint free, so you do not introduce extra lint particles.
Hope this is helpfull.

max...dear nichola: after these other people try this vacum and
q-tips thing we will be able to find out what it costs to replace
the sensor on a 1ds. by the way at my last cleaning the most
peculiar object appeared in the sky shot after cleaning, looked
like a fingernail clipping. at 100 magnification it turned out to
be a daytime one eigth moon. best regards.

Hi My Friend Max,
That qualifies as a little added reward for doing such a good cleaning!

I don't want to be seen as an alamist, but, just in the case of my D1x, I've heard estimates STARTING at $750 and going up to $1500 to repair and/or replace the CCD. With the amounts of money invested in our equipment, it's only common sense to do an exhaustive search for the SAFEST and most EFFICIENT way to maintain our imaging sensors.

To a lot of D-slr owners ( Newbies and veterans as well), there is definitely a case of denial when dust is even talked about - it doesn't exist, and if it did, it has no effect whatsoever on their images. They also get a little PETRIFIED when they read that some of us actually enter the "Chamber of DOOM" and swab the sensor. Well, I've chosen to do the exhaustive research, to get the PROVEN materials and implements, and to use the PROVEN safe and efficient method. But that's just me.

Once again, if you are happy with oil-laden blowers, smear-laden speck grabbers, fiber carrying Q-tips and nuclear-powered vacuums that may force dust in back of the AA filter, then it's your CMOS and, therefore, it's your choice. Good luck!

Take care Max,
Nicholas

this is wrong sense of security if you use any tissue since it is claims lint free. Only those that are made and claimed for high quality microscope optics. since many of these cleaning tissues can be used for other cleaning area such as computer screen, not needed to be as optical grade, or surface of metals, keyboards they only have to be lint free. Of course you would not find the effect once or twice cleaning, but definitly it will show upover time.

so stay away from anything that does not specify microscope OPTICAL grade usage.

Hi all

My take on this is that the less you introduce foreign substances (lint, fibres, cleaning fluid) onto the sensor and the less you touch it, the higher your chances of not damaging it or making the problem worse (eg, pushing dirt into the corners). It is very easy to get obsessed with something like this, one just have to accept it will never be as clean as it was when it left the clean room.

When I see dust marks, I tend to use the safer method of spending a few seconds cloing them out in PS. It takes longer for landscape shots with lots of sky and small F-stops but it is still a matter of less than a minute.

I have had the camera for 3 months and haven't "cleaned" it with anything more than a blower brush once a week and I have not suffered the problems others have experienced, maybe I am just lucky.

The camera is only one of the photographer's tools ....

Hi Arthur,

As you have demonstrated so well, we all have to be comfortable with our cameras and the fact that there may be dust accumulating on the CMOS. The biggest risk in proceeding this way is the fact that undisturbed stuck dust particles may become even more stuck over time. If this happens, you will first begin to notice a degradation in the contrast in your images.

If and when you begin selling your photographs to an ad agency, stock photo agency, web designers or publishers, you will be confronted with VERY exacting standards to be met. I have several accounts that require tack sharp images with minimal noise and no spots. I just can't take a chance on compromising the integrity of my images - the competition is fiercely professional in all of these areas. The personal standards in weddings and portraiture MAY not be as stringent, so you need to proceed accordingly.

Lastly, it is no big deal to send the unit to Canon for a cleaning, whenever you deem it neccessary.
Good luck,
Nicholas

Lee,

You've piqued my interest. Can you please describe your lens changing technique?

TIA,

After buying a mini vac for £8 I tried it on some talcum powder on a smooth desk.........you had to get within 2mm of the powder with this big sharp hard plastic nozzle before any of the powder would even move. Even if used in conjunction with a swab, you would have to go perilously close to your precious sensor for it to be used effectively.....NO WAY!!!

The Kim wipes I bought (for £3.00) seem a little hard but I seriously doubt they could actually scratch a sensor!

I know what you mean but there are certainly better mini-vacs on the market. The Mini Vac that sells for US$ 28 + US$ 12 AC adapter looks fine for us. (There's a link in this thread, don't remember exactly where.)

I would be extremely cautious about using normal Kimwipes on the imager.

I fab precision optics for a living (Like the Hubble WFPCII pics?) and we had stopped using Kimwipes 20 years ago.

I'll inquire as to what our coating and inspection people use now and report back tomorrow.

During normal fab inspection, we use ordinary Kleenex brand tissues, colored only, as the white ones leave a residue when cleaning with acetone and MEK, but they are very linty and wouldn't dream of getting near the imager with one.

In an ideal world, Liz Parker would exist

I've tried three of these mini vacs from $12-$35 and have none now.
To me, they were all worthless.

C0-2 Duster. (from: http://www.americanrecorder.com/catalog/default.php?cPath=10 )

don't use it, i tried to clean the sensor with it in my Canon EOS-1Ds. first time it was OK,but on second cleaning there came some moisture or oil on the sensor. Drops were clearly seen by eye and thry showed on all pictures like small dark rings with light inside.

now the camera is on its way to canon for reparation - i hope that they can clean the sensor, or it will be a new one for 3000 EUR. what a bad luck i had - and the cleaning in canon would be only 38,50 EUR.

bad-luck -
