Are ALL brand new Canon lenses defective?

[Ozarker]

You people are missing the point of my original question/statement.

I am sending lenses to CPS repair after purchase and just asking them to "check autofocus". I am not telling them that their IS a problem. However, Canon almost always identifies a problem on their own and fixes it.

Several years ago I was told to do this by a CPS rep at a trade show. Since then, I have done it soon after purchasing a new lens and the majority of times Canon has found something that was not up to spec.

It wouldn't surprise me at all if they're trained to say they did something (of significance) even if they didn't. It's customer care -- you want to make buyers of expensive components feel cared-for.

Your assertion would have some meaning if you had tested it thoroughly before and after, and had found significantly different performance.

Exactly. The poor guy has something wrong with every single lens... while most everyone else on the thread has had zero issues. 1. Buy a brand new lenses (How many is anybody's guess). 2. Send it (them?) straight in for service. 3. Canon finds something wrong with it (All of them? How many?). That really sucks. Glad he ran into a trade show rep who is there to promote the product that pulled him aside to say, "You know, our lens QC really sucks. You should send every lens in and have the service center check AF. Our product is so bad, trust me, they'll find something wrong. Keep buying Canon though!"

Interesting, CPS finds a problem every single time... but the CPS member hasn't stated there was anything wrong to begin with.

What I am saying is that I will send a lens to Canon and just ask for "clean and check". Then Canon identifies a problem. I am not telling Canon that I am having a problem with the lens. They are finding it, or so they say. Some lenses just come back saying cleaned, everything is within spec.

Wait, first you said EVERY lens had a problem. Now you say, "Some lenses just come back saying cleaned, everything is within spec." Guess you answered your own question. No, all brand new Canon lenses are NOT defective... according to you.

They put some Balm of Gilead on the lens and send it back, all fixed up.

Same like with cars, usually the problem is the loose nut behind the wheel.

or with computers (Error in front of Screen) EioS

 

[1982chris911]

No.

There was one sold in 1973 that was OK.....

That theoretical perfect lens - only no one knows where it went ...

Dilbert has it. If only he can find a camera worthy of it.

I call that a "layer 8 problem"

I was about to write as an answer to this post: Yes! (If the user is defective ;D ;D )

I have gotten in the habit of sending my brand new lenses to the Canon Factory Service Center for warranty repair immediately after I buy it. So far every lens has had something wrong with it. This week I sent in my 11-24/4 and my 16-35/4 and both of them had the same problem. The autofocus module was out of alignment causing slight front focus. Does the Canon factory just not get them right? Are the tolerances for new equipment not up to par with the way CFS specs are?

Interesting... Why do you send your new lenses in for service without even trying them?

I've purchased over a dozen Canon lenses new over the last five years and the only time I've sent one in for service was when I dropped my 70-200 2.8 II and damaged it. All of the lenses I've purchased have worked great out of the box with a little AFMA adjustment to my bodies.

You are using this word "defective." I do not think it means what you think it means.

 

[Loswr]

Inconceivable!

 

[Machaon]

For what it is worth... I'm usually a little annoyed when I go through the process of afma'ing my lens and it is right around 0. I think, I just spent an hour for nothing. Then just to warrant the time... I go +1 or -1...

I suppose that instead of wasting time on the AFMA, you could just send it in on warranty as soon as you buy it...

As a contrast, I have a 100% return history with Sigma, because their AF has been inconsistent and useless (have just ordered my 3rd 50 Art, to see if they have fixed it).

Like you, I have never had a defective Canon lens.... or Olympus... or Nikon.... or Sigma..... but I did send a Tamron lens back for a free firmware update and cleaning.....

Just wait ... The one whose name shall not be spoken will soon find it ... :

Only time I ever had an issue with a Canon lens was, oddly enough, after I dropped the damn thing. CPS did find something wrong with it after that. Must be some conspiracy...

Kidding aside, I actually JUST two days ago did a focus check on all my glass using both my 5D3 and 5DSR. My two Sigma ARTs needed some adjustment, and that handly $50 USB dock did the trick perfectly along with firmware updates. The Canon glass was all dead on. MF adjustments accomplished nothing and it was already spot on anyway. Not too sure what more a guy could want there.
