A History Of Dust Spots

Hi All,

I was noting the other day how dust spots have affected my camera equipment over the past few years of photography and would be interested to know if the same issues have been experienced by other users.

I started off in January 2005 with a Canon EOS 300D and quite a few lenses. At that stage I was trying to figure out which lenses would suffice my needs. Obviously I was interchanging lenses on quite a regular basis. What was interesting was that I never had a dust spot problem with the 300D.

In January 2006 I upgraded to the Canon EOS 20D and also reduced my lens number quite drastically. However, I began to pick up dust spot problems within the first six to eight months of use even though I was interchanging lenses less frequently.

In January 2008 I upgraded to the Canon EOS 40D and now only have two lenses in my bag with the Canon 24-105L IS lens almost permanetly attached to the body. Horrors to say is that by February I already have a couple of grotesque dust spots rearing their ugly heads on my pictures. I was quite surprised since the 40D comes with active dust spot removal. I will however be taking the body through to a technical specialst for a "blow out" soon.

An interesting history of dust spots none the less.

I have had similar problem with my old and new camera.

I start with 300D and suffered no dust spot, bought a 10D which had a dust spot when I bought it and when I take it back to shop, they did not know what it was and exchanged it for the newer model, the 20D. Now using a 5D and 1D2N with just one lens on each one and get more spots than ever.

Where i live there is a place which does the cleaning but it takes 3 hours as they remove the sensor in sterile condition. I used to use the pec-pads to clean my sensor but found it sometimes makes the problem worse so now I just 'heal' the dust spots in CS3 and get my sensor cleaned professionally once a year.

Living in a cold, dry climate (read that as "staticky, dusty environment") dust spots are always lurking. Before major commercial shoots (such as weddings) I always clean the sensors. Sometimes it lasts a few days, sometimes many months. But I can't afford to shoot off 1800 pic's at a wedding and have to clone dust out of them all...

It's no big deal really - a blower usually does the trick, but I haven't encountered anything that the swabs can't get. Sometimes it's tedious and takes a couple tries, but I can't afford to have a body down for hours while someone else cleans it (let alone the cost).

CalgaryBill, you must be good with the swabs as I have tried on number of occasions to clean with swabs and seem to make things more bad leaving dried smears across the sensor.

Also, I am informed that the sensor has a sticky area around the edge which is for catching the dust and cleaning with the swabs can be bad for this?

If you're leaving smears try using less fluid. Just use one drop, maximum two, and let it soak for 10 or 15 seconds before applying so the fluid spreads evenly through the swab. Also use the blower first before swabbing so there's less stuff for the swab to pick up (or smear!).

I'm not sure about the Canon, by my understanding with the Nikon is that the sticky strip is recessed on the edge so a swab won't hit it. Got that from a Nikon rep though, not a technician.
