I was excited for 5 mins before I used a flash light to inspect the new 70-200 f2.8 is II I just received. Couple white particles/dusts sit on different internal elements and moving along with the element when I turned the zoom ring. They are pretty good size and obviously noticable which I think it is not acceptable for a $2000 new lens with internal zoom sys. Just wondering how offen guys receive a new lens with a similar internal dust issue. I found my recent purchased 100mm F2.8 IS Macro also has dust inside but they are pretty tiny and I can live with that. Canon ever advertised their dust-free production line in a video last year but I think they didn't do a good job this time.

Requested an exchange with the retailer. I have been told retailer cannot inspect lenses prior to shipping under the terms of their supplier agreements.

That would make sense, it would break the factory seals and it also protects you, as the consumer, so you don't get a lens that was used and just repackaged and sold as new.

I would also request an exchange, or send it to Canon for a full check and clean (although that can have mixed results).

Hmm, very disheartening... I've got that exact lens arriving today. I would send it back immediately.

I'm pretty sure that lenses are not "factory sealed" and neither is most (if not all) Canon still equipment. So while it is conceivable that the lens could have been opened and repacked by someone, I doubt it. Most likely the lens came that way from Japan. These things happen, and while it will not most likely not affect your images at all, I would probably not be happy either. So, if the retailer is willing to exchange, then I would persue that option. (Perhaps they'd be willing to inspect the replacement lens before shipping it back to you...?)

Two things you should never do:

1. Never look into the kitchen of your favorite restaurant
2. Never shine a flashlight into a lens

Many lenses will show some internal dust motes--they always have. A few dust motes do not affect the optical or mechanical function of the lens. It's not a reason to reject a lens.

I don't know what Canon may have advertised last year, but the pictures of their assembly line I've seen do not portray a dust-free "clean room" facility by any means. Clean rooms are quite expensive propositions to maintain and operate.

I think that it would be exceptionally hard to be 100% dust free. My guess is most new lenses would have a little bit of dust inside.

You can try to exchange for one without, but you might be hard pressed to find one (if you're inspecting it that hard).

Unless it is a huge speck (and even if it is a large dust speck), chances are it will not affect the image (even if you stop down to f/32).

Think of it as the special Canon dust that you paid extra for.

RD beat me to it!


Thanks for Reading & Good Luck - Jim

CR told me they can not inspect the replacement lens due to the supplier agrrement from Canon. It's difficult to tell whether or not the box been opened before as the way Canon sealed the boxes. I wish they will not repack this lens and pass it to the next customer.

Personally, I would not return it unless you don't want that particular lens. If you have them do an exchange, you are likely going to get another one that is the same.

I agree with RDKirk. I don't think I've ever shined a flashlight into a new lens upon receipt, or at any time during its life unless I had some problem I was trying to diagnose. The first thing I do is mount it on my camera and start taking pictures with it to see how it performs. Whatever you are seeing is unlikely to have any affect whatsoever on the image. To me, this would be like rejecting delivery of a new car because you find a couple spots of dirt on the frame rail under the hood of the car.

Or you could keep exchanging them so that Canon has more perfect refurbs for people to buy. :)

I am sorry if Canon use it as an excuse for jacking up the new release lens' price .

I would just go out and enjoy it. I picked up a new Tamron 17-50 with some dust inside and was fine. I ended up shooting at the sky at f22 a few months after I have been using it and being happy with it and did not noticed the dust at all.

Not getting dust inside a lens is like not getting fingerprints on a new phone. It's gonna happen.

doesnt make a difference if theres a little dust inside. doesnt harm anything and after about a month of using it dust will be there anyways.

as long as it didnt come broken or making weird sounds... just go shoot and enjoy

For 2k they can make sure there is no dust inside - the lens is weather sealed and doesn't exchange air w/ the environment - some air moves around internally, I would imagine you would have to be doing mega quick zooms to have much risk of dust flying around on the inside from zooming. Loose dust is simply unacceptable.

I just double checked any my 70-200 has zero dust, as the 17-55 neither and it isn't weather sealed.

If it bothers you send it back. I would indeed take several reference shots that you can reproduce exactly for the replacement lens. The 24-70 2.8 II is having some QC issues as detailed in some other websites and lens rental companies.


If you see me with a wrench - call 911. 5d3, T3i, 17-55 2.8, 50 1.8, 70-200 2.8 L II, 24-105 f4. YN 565, Precision Lupe attached to hacked extended eyecup (no sticky frame) - old enough to have owned an original F-1

Nope. A "clean room" assembly environment that would guarantee no dust would drive up the price considerably.

Use a loupe and a brighter light.

The dust free Canon lens is a myth.
