Has Canon resolved the dust problem with this lens?

I had never heard that before, where did you read that?I haven't had any problems so far with my lens

After nearly 2 years with my copy it's fine too. I do have a pretty large speck of dust in the front element but it doesn't affect anything. You have to keep in mind that dust in the front of the lens does not affect image quality so it's a non-issue. Certainly should not be a factor in the buying process as the lens has some amazing strengths.

No dust problems either after years of use. I've had a protection filter in place from day one though.

Nope but it works super fine...I have been using it for 2 years and I am very happy with it

Have had the lens for a while now....It's been in some pretty dusty places - Including a few National Parks as well as the Beach. Never really experienced the "Dust Problem." Great little lens that delivers beautiful photos. Great walkabout lens for my 60D. Saving for the 70D as we speak.

I purchased a nikon refurb d600 and have had no dust problems in the last year of ownership, shooting several weddings, lots of long exposure / astrophotography, etc.

Not sure I can be of much help.....I haven't tested all of the "elements" that you listed as threats to the lens - really haven't experienced extreme conditions under rain or sea water spray - some, but nothing severe. Living in Oklahoma I know my lens is exposed to dust. All I can say is that there is no apparent affect on my lens or camera to this point...but then both are still relatively new. I trust Pentax to perform as promised. My K30 is my "fourth generation" of Pentax - Spotmatic, ME Super, Super Program, K30.

I haven't had anything like that happen to mine. I was just looking at the lens and honestly I can't see what might fall off in the way of a thin, plastic circle or ring. If the camera is still operating properly then I'd say keep taking pictures. With hope the now-missing circle/ring hasn't left an opening where dust and dirt can get into the lens or the camera itself. Keep us posted.

I clean the camera lens on my iPhone and the lenses on optics with no problems. I do follow up with a micro fibre towel which makes it perfect. Otherwise there is a little tiny bit of residue, You can't see it but it's there.

I have a friend that is having trouble with the ZS-8,just a little dust or dirt and the lens shutter will not open. He is battling Panasonic right now for a fix.Alfred

I checked this problem out prior to purchasing this camera. Found this YouTube video on cleaning the dust off the sensor. http://www.youtube.com/watch?v=q_sP4yLf6lA Pretty common problem, easy solution.

Haven't had that problem. The manual just says turn the camera off and check the connection. I'd worry that the lens electronics were damaged.

No, it's not dust in lens. It is moisture condensation. Now, the camera is dry. Every picture it took is great without the ghostly translucent round spots. Guess the problem I have is different from yours.

Yes and no. There have been a few alarming SDM/Autofocus no-work moments, but a remount of lens and camera on/off has always fixed them immediately. We both use this lens all the time, so counting the one I smashed, we have direct experience with 3 of them.

Sorry this is late, but yes, I have had no problems with it other than dirt and water getting on it. I did follow another persons suggestion about coating the seams with silicone and I have had no issues with it. Works really well for the price. Hope this helps. I did not apply silicone to the lens, didn't want any distortion.

I do but what you can do is take of the lens and clean itSometimes dust settles within the lens

If screwed in properly it should help keep any moisture and dust off of your camera lens....I have not noticed any problems with my lens an this time.

I do not agree with J. Gland. You can have a weather resistant lens and a Rebel body. You can clean your camera sensor a lot easier than the internals of a lens. Also, your camera body depreciates in value as fast as a new car or computer...you're lens will hold it's value... One way to really avoid dust is lenses that do not extend while zooming.I've had mine since May 2007 and have used it at the beach, in the Rocky Mountains, at home, in Italy twice, etc... If you look into the front element there are several specs of dust (5 or so) if I look hard enough. They have no effect on image quality. Great lens, wish it was built a little more like an "L", but it's the best compromise for zoom range, 2.8 and IS. I do not agree with J. Gland. You can have a weather resistant lens and a Rebel body.

No, I'm not aware of any updates to the seals on the 17-55. Yes, an f2.8 lens needs only half as much light as an f4. That means you can use a 2 times faster shutter speed or a stop slower, less noisy, ISO. Plus the f2.8 will give you more background blurring which is very nice for portraits where you want to isolate the subject from the background. I did a quick review of lens dust threads on the PhotographyOnTheNet Canon forums and found dust threads for pretty much every Canon lens that extends when zoomed as well as a few other third-party lenses that aren't considered inexpensive. Interestingly, none of these threads actually mentioned finding a degradation in image quality which lead to the discovery of internal dust but, rather, were started by someone who inevitably looked through the lens with a flashlight, saw some dust and grew concerned. I'm of the philosophy that if it ain't broke, don't go looking for problems. ;) (When I last bought my brand new car, I made a very conscious - though difficult - effort not to look for scratches in the paint after every trip to the grocery store.) The general consensus is that SOME amount of dust in the lens will not affect image quality whatsoever. Many owners of the 17-55 also report that installing a front UV filter has kept their lens pristine (I've also kept my UV filter on at all times except when using a CPL filter so perhaps that isn't an unreasonable conclusion). Apparently there are three small hidden vents on the front of the lens a filter will seal. Furthermore, one of the long time members of the forum has published do-it-yourself instructions for internally cleaning the lens and others point out that Canon will give you a free (minus postage) cleaning and adjustment while the lens is still in warranty. I guess what I'm trying to say is that it really isn't something worth worrying too much about under typical conditions.

Dust happens. You do have to be very careful when changing lenses but it somehow manages to get there. When cleaning the sensor, however, be very careful and use ONLY special sensor cleaning products. Don't use your lens cleaning stuff. It is very fragile and can be scratched easily.

The thread is there but it's a smaller diameter than most of the other E-type lenses so you will need a new set of filters. The lens is very compact but the images need to be corrected for distortion. SONY provides software for this as do Photoshop and LightRoom.
