Dust inside lens okay?
I recently purchased a Canon 17-55 IS 2.8 lens. I notice there are some dust specks inside the front glass of the lens. Looking even closer I see some dust on the glass inside the front lens also. I expected the lenses from Canon to be completely dust proof within the lens itself. Should I be concerned? I am new to SLR's and I have heard dust can be the death of good photos. I am not noticing it on my laptop when reviewing photos but I also have not printed anything yet. Please let me know. Thanks!
Return it for a different one.
I just had the same problem with a Nikon 18-200 VR. Being assembled in a clean environment means there should be nothing inside that lens but glass and air.

A few particles of dust inside the lens will never be seen in a photo... they will be so 'out of focus' that they won't show up. Dust on the camera's sensor is another story.
However... on a brand new $1K lens... I would expect better. Take it back for exchange, IMO.

I have this lens and it is noted for being a dust sucker. Mine is no exception. It is pretty bad at this point but the IQ has not changed from day 1 when it was perfectly clean to today when it is perfectly dirty. You could exchange it but the condition will likely repeat itself. Exchanging it for the exact same unit will not change something inherent in the lens design. The amount of dust that gets in varies more with environmental conditions vs. use than anything else. As long as it doesn't effect the IQ I say the dust is much ado about nothing.
The respect of those you respect is greater than the applause of the multitude.
Thanks for the replies! Do you know if something like this is warrantable with Canon? I would at least like to start off with zero dust if possible even if it means accummulating over time.
i don't know but i also got dust inside my 24-70, which is a weathersealed lens..i sent it back for cleaning, it came ok, now again specks inside...
will i be charged to have it cleaned again, like they clean the sensor only once for free?
anyone, any ideas?
This problem is widespread... Shame on canon.. My 18-55 kit lens has one dust particle in it.. but it's only worth $180 bucks... if I got a lens for $1,000 and had dust in it, I'd be furious... I will never buy the lens you got only because of the widespread horrible dust issues... They actually pull dust in, even if they come to you clean... terrible for $1,000..
I hope the 16-35mm L II lens is not like that..
If it bothers you and its still under warranty send it to Canon for cleaning. If its out of warranty, you can clean it yourself....(Its a piece of cake - I cleaned mine recently)....

Good lord ... a home-fixer-upper lens!
I guess Carl Zeiss has one of these, too. Makes you wonder ... how they got these past testing? This would have been one thing I would have tested for, in the design stage, for sure: Under the heading of Environmental Contamination. Forget the dust ... how about high humidity, like in Florida and Brazil? If dust is getting in at this kind of noticeable rate ... there goes the neighborhood.
