[EDIT] My 70-200mm IS lens is buggy

okay, look at it this way.

You go out and buy a top of the line Sorny VCR for some special event you want to record.
You get it home and set it up only to realise that it works okay but it wont actually record.
You look on the net and find that this top-of-the-line Sorny VCR has had reports of the same problem from a few people.
You call sorny and they say "yes we are aware of the problem on a few of these machines - send it in and we will fix it".
Of course they want 3 weeks to fix it and by then the event you wanted to record has long passed.

How do you feel? Should Sorny actually be allowed to sell that VCR when they know that a few of them have bugs?

Using your criteria, perhaps one should search the net first to see which model(s) don't have issues...

Anything made by humans can be defective. As mentioned above, the percentage of failures is the best test of determining crap versus bad luck.

It doesn't feel very good to be the one that got the defective unit, but I'm having a tough time with the argument of poor quality control based on one unit.

My two cents.

Have Fun,

Sorny? If you mean Sony, I've had to send two of my top-of-the-line Sony VCRs in for repairs quite early in their lives. A third Sony VCR was replaced by the store since it started having problems in the second week.

I felt annoyed but I remained reasonable. (My experience with top-of-the-line Toshiba and NEC VCRs was much worse by the way.) This is a perfect example of what I was talking about earlier where people in one forum use the products that people complain about in other forums as examples of perceived higher quality. Thank you!

In a free country with a free market - absolutely yes. If you require bug-free products then you need a different economy than the one I live in and a different kind of engineering to produce them. I can't think of any product that has no design or sample bugs.

Even Mercedes makes lemons. Stuff happens. It's a fact. It always sucks when you are the one getting the lemon and yes, it's easy to say just deal with it when you're not the recipient, but I had my 100-400 go belly up on me and though I was bummed it happened I was not crying "compensation" from the rafters either.

And also: Sometimes products are released with known issues. I beta tested for a software company for 6 years and when the release date came, the software went out with known bugs.

Lets see, god made your heart but sometimes it's defective and he has made billions and still gets a bad one in the batch. Man made electroincs and I know man is not perfect so every once in a while we get a bad one.

I got my 20 D and thought I had a bad one because a saleman at B&H said he has been doing this thing all his life and let me tell you this Camera does not focus, bring it back to Canon. well I brought it to my local Camera store and he put a different lens on and guess what perfect, sharp pictures. It was not the Camera but the Sigma lens and the idiot saleman who knows nothing making a comment on something he knew nothing about.

My point, do you have the IS on the right mode as I understand it if it is not it will not work properly. Second are you using a 20 D and if you are it had issues with certain lenses inculding Canon. When I did the firmware update it solved all my problems.

Now if it still does not work then you got one of gods mistakes and I would return it to the store and try another.

and the guy who would have bought a NIkon, I owned them and like god they make mistakes also.

I love Canon's, they make good Cameras and lenses. Are they they only ones who do, no. Nikon/Olympus/Minolta/​Pentax also make fine equiptment but when it comes to inovation Canon has them beat, so I will take all the problems and work on them one at a time till I have the product thats perfect.

don't start sigma bashing

Yeah.

At least start a new thread for that.

Thanks to all for replying to my thread

I would like to thank every one who shared their thoughts. While I may not agree with every one, I do appreciate that the fact that you posted them. That is what a forum is all about.

Jim

Wow Jim - hot topic huh!

As we discussed on my prior thread https://photography-on-the.net/forum/showthre​ad.php?t=45460, Jim is having the exact same problems I had with my new 70-200 f/2.8L IS lens mounted on my 300D. I sent it in to the CA Canon repair site and finally got it back a little over one month later. It seems okay now, but I admittedly haven't had time to take too many pictures with it to totally erase my fears.

Judging by the number sold and other accounts, I agree it's a great lens, but it does appear their quality control of the IS feature could be improved. The bottom line seems to be if you get repetative problems and the contacts are clean, arrange to return it for repair and be patient.

I am not bashing Sigma. The 20D had issues and because of these Sigma rechipped my lenses in three days. I sent it Wednesday and friday I had it back fixed.

I've had my 70-200 IS for over a year now and just about 4 months ago it started the mirror lock-up routine. Didn't matter what settings I had on the camera (1D) or the lens. Low or bright light, IS on or off, high or low shutter speed, camera vertical or horizontal makes no difference. It just decides on it's own when it wants to mess up. Only thing it does do, is give me a little warning before it happens by spooling up the IS motor (even with the IS off), When that happens, the mirror locks-up. The only way I can clear it is to take off the lens and reinstall it, and remove and re-install the camera battery pack. Just turning off and on the camera won't clear the 'err' mesage...

Been too busy shooting to call Canon, but will be tomorrow...
