17-55 f2.8 and Dust

I just got a 17-55 f2.8 IS and 30D. I've only taken maybe 3 dozen pictures and to my surprise the lens already has a lot of dust inside! There is more dust inside than on the outer element. I have not even used it outside yet. So, what's up with that? Don't think there is anymore I can do to prevent it. The camera is in my bag when not in use.

Thanks,
Brent

Hello,

I can't answer that question, but I have another. Since you have this lens, can you please tell me if it supports full-time manual focus? By that, I mean can you place the focus switch into AF, press the shutter button down half way (or press the '*' button, depending on your setup) to focus, and then grab the manual focus ring and adjust without flipping the AF/MF switch to MF?

According to Canon's website, this lens does not support FT-M, but that seems hard to believe.

Thanks in advance.

Been brought up a few times already as it seems to be something you'll have to live with in this lens. As long as its not effecting your photos is the thing to be most concerned about.

Yes, this lens has ring USM and FTM. Now go buy it.

Yes, I guess that is what I am really asking, is dust doing to degrade the image to any extent or is it just blocking a minute amount of light? Otherwise, a fantastic lens.

seems to be common with that lens

I wrote to Canon:
INQUIRY: I have heard from quite a few people that have this lens, that
alot of dust or lint gets sucked into it. could you explain how to have
this not be such a problem for such a lens, and what effect will the
dust make in photos?
can these lenses be sent to Canon for cleaning??
thankyou in advance

Canon has not announced any issues with excessive dust issues with the
EF-S 17-55mm lens.

If dust enters the chamber it can block light if enough accumulates.

it is a robot... hate automated messages where they just change three fields..

Those of you who have purchased the Canon 17-55 and experienced dust getting inside should start to be vocal in your complaints to Canon! This dust issue in the 17-55 is simply being encountered by owners all too frequently. If the public can raise an outcry about the 24-105 flare issue, it should be able to raise attention to the dust issue of the 17-55, too!

Well, it is a little ridiculous. I have not used this lens for more than a hour yet and I can count 12-14 specks of dust sitting on one internal lens element and again, this is indoors in a clean environment.

Can you post the date code, and place/time you purchased from?

I don't see a date code, it should be beside the rear element, right? It arrived last Thursday from B&H Photo. I have emailed them and Canon.

I have been watching the 17-55 2.8 IS Dust threads carefully and will continue to do so for the next few months. I don't know that anyone has actually been able to prove that it has degraded their image quality with this lens, but I wonder if it'll be the same situation once people have been able to use it for a year? I'm planning a big trip to Spain next year and want to take my 20D and one lens. It's maybe a once in a lifetime trip, so I'm considering buying this lens before I go. But, we'll see if this problem really is a problem long term and if Canon recognizes it and does anything to correct it. I'm keeping my fingers crossed, because this seems to be nearly a perfect lens otherwise.

remember canon will clean it for free only when its in warranty, otherwise i think there stand alone charge is about £80, this may vary between lens.
