Dust G7/G9

Ed B · Oct 21, 2007

I really like the G7 but mine is on the way to Canon service because of dust on the sensor.
I hope, for all you G9 owners, that Canon has this problem fixed on the G9.

My G7 is about 7 months old and I didn't think I was going to experience the sensor dust problem but sure enough it showed up a few days ago. Big spot right in the center of each picture.

I guess this wasn't a very interesting thread. Sometimes I think I'm talking to myself.

paulobiz · Oct 21, 2007

Well, what can I say that would be useful? Dust is everywhere? We breath it in and out? The particles are so small that even make their way into fixed lens cameras?

This is not a Canon problem, it's just the way things are. In the end, dust is much less of a problem with digicams than DSLRs.

For the reocrd, I also had a dust problem with my G7.

I guess the solution is to store your G7/G9 in a less dusty environment. I agree that dust is not something that we can actively avoid. It's so small that it'll be near impossible to filter out of our daily lives.

It is not that anyone is not interested in your comments, it is just restating a fact most already know!

I've had dust in my G7 too but I decided to try and be pro-active with my g9 by buying a lensmate and UV filter for the lens, I'm hoping that this may provide more defence than the leather case did.

I guess we won't know for a while... :O)

What bothers me most is that this has been a problem on the G7 and has not been a problem on other Canon compacts, with a zoom lens.

Does this mean that after Canon cleans the sensor and sends the camera back to me that I can expect the sensor to have more problems within the next few months?

Once the one year warranty has expired, I'll be stuck with a $500.00 + camera that is defective because of a design deficiency.
That doesn't sound like a good thing to me.

Ed,

You've hit the issue on the head. It is indeed a real concern and those who think dust is to be expected are mistaken. Canon's engineers have overlooked an entry where dust is finding its way in. One would think if Canon were paying attention it will have been fixed in the G9. Never have I had a dust issue with any P&S, Canon or otherwise, and I'm sure you'd be hard pressed to find anyone else who has had a dust issue. I'd bet that those G7 (G9?) users who have to pay to have the sensor cleaned after warranty will certainly give long thought before buying another Canon.

Ed B · Oct 22, 2007

Well, the people who think this dust problem is normal or who don't seem to be bothered by it are either very inexperienced or are very apathetic.

One guy even told me that his DSLR got dust on the sensor and indicated that I shouldn't worry about the G7 dust. Another basically said that if I use it in dusty conditions that I should expect dust to get on the sensor.
Some people, on this forum, don't realize how comical they are.

I've used Canon cameras and lenses for many years so I can't say that I will never buy another Canon camera but if they can't fix this problem I'll be disappointed, to say the least.

The Canon sales representative visits a local camera store here about every 3-4 months. Guess I'll cry on his shoulder the next time I see him. Won't do any good but at least I'll get to hear him stutter and make up excuses.

Many people in this forum are far too accepting and apathetic and yet you are often berated for pointing out problems with their cameras. Strange.

fanboy · Oct 22, 2007

Dust is indeed a fact of life with dSLR camera. Dust on the sensor should NOT be considered acceptable on a correctly designed P&S digital camera.

Thanks for bringing this issue to light. It is a real issue. Too bad too, because the G9 looks like a very nice camera otherwise.

Greg Gebhardt · Oct 22, 2007

Any camera that the lens extends and retracts when you turn it on and off will suck air and likely dust into the camera.

This is fact

Unless specifically listed as a feature, even digicams are not dustproof.

They may not be dust proof, but there seem to be a LOT of people with problem with dust on the G7 (myself included). My G7 is not that old and has a dust in the lens. I don't believe it's been in worst condition than my S3 witch I travel with in Perou during the winter season (or as I called it : the dusty season) and the S3 didn't get any dust in the lens. Maybe it's just luck that I didn't get anything on the other camera but I believe the G7 maybe worst as letting dust inside.

As someone who has owned two canon powershots, a Fuji finepix, a sony dsc-v1, a nikon cp5400 (and two Olympus DSLRs) and used all in dusty environments and stuffed them into dusty coat pockets - I've never had dust once. Frankly if the G7 or any other fixed lens camera has a known dust problem it is a design fault and owners should complain loudly.

Well, perhaps you should try and shoot film, but wait, what about scratches and retouching for endless hours??? I am sorry, but it is you that come out as inexperienced. Dust is a fact of life, and nowhere in its literature do Canon state that the G9/G7 are dustproof. Is it annoying? Yes, sure. But just move on.

Particles will inevitably find their way into the zoom lens it happens with all lenses.

Well, what can I say? I had dust in the G7 when I used it for two days in the Arabian desert, under strong winds. You know what? My EOS 1V SLR developed some strange symptoms in the shutter button at the same conditions. Want to know more? My EF 24-70L lens had some very fine sand entering underneath the manual focus ring. Know what? It seems that there is indeed a correlation between shooting under dusty conditions and dust problems!

I also remember a friend's digicam (not Canon) just dying after 10 minutes in the desert. Some sand grains blocked the leaves of the lens cover!

Indeed...

Greg,

I have a G2 that is several years old. Have used it for every picnic, school play, and at least 5 family vacations in the last few years. Two years ago I took it to the mountains for a two week camping trip. That little lens has gone in and out thousands of times and guess what. No dust on the sensor.

If you really think this problem is normal for a compact camera then you are a complete novice who needs to check his facts before pretending to be an expert.

And before you misjudge me you need to know that there is no bigger Canon "fanboy" than me and very few people on this forum who know more about Canon cameras than me.

Fixed lens compact cameras that gather dust on their sensors are defective. And if you don't believe me then I have a bridge in San Francisco I'd like to sell you.

Ed B · Oct 22, 2007

Please read my response, below, to Greg. I believe it also applies to you.

And, I didn't mention anything about dust in the lens element.

I'm talking about dust on the sensor. You do know there is a difference, right?

avicenanw · Oct 23, 2007

I absolutely agree with Ed and Wolfie. P&S that have dust in the lens or sensor is defective. I own a Minolta G500 for several years and have taken pictures in extreme environments and NEVER had a dust problem.

Probably. That does not mean that a P&S digital, with no way for a user to get at the sensor for cleaning, should not and cannot be designed for the sensor itself to be dustproof. If a P&S digital is getting dust on the sensor, then it has a design flaw.
