Canon issues allergy warning for EOS 650D/Rebel T4i

By dpreview staff on Jul 10, 2012 at 02:21 GMT

Canon has issued a warning to owners of the EOS 650D/Rebel T4i that the rubber hand-grips of some models may turn white, and produce a chemical that can cause an allergic reaction. According to Canon, the chemical, zinc bis (N,N’-dimethyldithiocarbamate), is not used in the production of the camera but is a potential by-product of a chemical reaction between other substances found in the hand-grip. Canon has identified a certain number of cameras where a larger than normal amount of 'rubber accelerator' was used in the production of this component, which could potentially cause this chemical reaction.

Canon has set up a website where you can check whether your model is affected. Click on this link and enter the serial number of your camera, and the site will let you know whether your camera is from the affected batch.

The hand-grips of some EOS 650D/Rebel T4i cameras may become discolored due to a
chemical reaction caused by substances used in their manufacture (image: Canon Inc.)

According to Canon USA, 'some EOS 650D/Rebel T4i cameras' manufactured between May 31st and June 15th 'may be affected' by this chemical reaction, which causes the hand-grips of the cameras to turn white. Zinc bis, the substance produced by the chemical reaction, may cause an allergic reaction in some people, and 'as a precautionary measure' Canon advises owners of affected cameras to 'thoroughly wash your hands with water if they have come in contact with the rubber grip'.

When I went to pick up this model from a local store, the first unit they took out of the box had white stains on the rubber grip. They had no idea what's wrong with it, but put it back into storage nonetheless and brought me a second one and it looked fine so I took it home. But after checking the serial number of the unit against Canon's database, my unit is indicated as affected by this "defect". It's been 10 days and I haven't seen any whitening on the grip yet nor have I experienced any allergic reactions to it, but since we do not have the same kind of exchange policies as Canon USA over here, I can only hope the grip stays black for as long as I own this new body...

The serial number on my Canon 650D body is 048031004102, so if your 650D is anywhere near this number (assuming the product S/N runs sequentially), you might want to check and see if your 650D is affected.

I think it is easier to trust a company which publishes errors than a company that doesnt.

Think how many plastic object you use. Do you really think that everything is save? All the nitty gritty things which are made somewhere in the world by some companies without a well known name aren't well controlled.

Let's see such a procedure as a side effect of our modern lifestyle with vast amounts of things made of plastic (rubber, etc.).

The main issue here is the fact that every company has hundreds of experts who are involved in the process of developing a new product. Since Canon is no newbie to camera production and the given model has a decent predecessor there really is no excuse for such production error.

Plenty of excuses for production errors. Some worker put 100 grams of catalyst in the rubber batch instead of 10, or whatever the real numbers are. Sometimes things like this show up really fast, i.e. the rubber does not cure at all or cures to fast to mold parts, sometimes things are going to look normal when produced and the issue is only seen many days, weeks, months later. Canon identified the issue and will take care of the problem. They can have inspectors at each step of production verifying that each step is done correctly, but that adds a huge amount to production costs and as far as I know that level of oversight is only done for aerospace related products. Even with inspectors things can be done wrong.

That's one reason why i like live view with side-hinging monitors - you don't have to press these toxic heaps of allergenous plastic to your sensitive facial skin, to your precious eyes and mouth. And see - the 650D has live view with a fold-out monitor, just so to keep the danger away from your face.

@rhnrt - you're correct, but the 5D III didn't suffer from a 'light leak' in the conventional sense of there being stray light entering the mirrorbox and ruining exposures.

In a related incident, Kodak (remember that brand?) advises that some of their film negatives may smell of formalyn and sulphur dioxide... while inside film cameras.

"Canon advises owners of affected cameras to thoroughly wash your hands with water if they have come in contact with the rubber grip"

What are the odds your hands would come into contact with the hand grips?

I'd guess.... 100%. There really isn't much "if" about it.

What a bizarre remedy for a poorly manufactured camera part.
The affected cameras should be recalled and the defective parts replaced.

You mean like the part where they say:

Once this repair service is available (ETA of mid July 2012), we will post an update on our web site and also notify registered users via email. Please register your EOS Rebel T4i, so that we can inform you via email when the free repair service will commence. "

And the part where they say "thoroughly wash your hands with water if they have come in contact with the rubber grips that have turned white.", which means there is no reason to worry if they haven't turned white.

From the statement, it seems like an impeccable reaction on Canon's part, pro-actively correcting a defect before anyone even noticed it. And it also seems you should read articles fully and try to understand them before spewing idiocy.

Canon would do better if it explain the chemical reaction that produce this by product from the rubber accelerator. Humidity and high temperature all affect the life span of any rubber but we were not told from what kind of substances that rubber accelerator is made. Hands are (but its nature) very resistant to allergies and I suppose that the out of the range pH of the substance (acid or alkaline) is the cause of the injuries, chiefly in the eyes, and not a true "allergic" reaction.
