Actually, i take back my words..the fact that light can leak from the top to the sensor, means that the moment you remove the top cover to "fix" this issue..means dust will definately enter the sensor area…
So i don't think i'll be sending in my camera for this "fix"

Not sure why so many people are confused by this issue.  The light leak does not...Not...NOT...affect the imaging sensor.  The light leak affects the metering sensor (which is in the pentaprism housing that protrudes up from the body), which affects the exposure determined by the light meter.  The image is not directly affected. 

(Plus, I'm pretty sure that Canon Service can work on things inside the camera without messing up the imaging sensor, I mean, things do go wrong in there, shutter failure, etc., and Canon can fix them, right?)

Looks good to me, but still not going to bother sending mine in.

Tape is everywhere in electronics. It's all over my motorcycle. A device that carries me to 170mph, rain or shine, hot or cold. Tape is okay. The only place i can recall not seeing much tape was inside high-end audio gear. But that's just because they use the clean layout and lack of things like tape as a selling point to blow the mind of the innocent. Many audio guys would rather sleep with their amp than their wife.

Duct Tape:  It has a light side and a dark side, and holds the world together!

There may be three species then: 1) untaped leaky originals 2) tape kludged originals and 3) revised design without tape.

4) the DiY fix.   :P

This is funny. It reminded me of an old story. A guy wanted to steal a bell hanging on his neighbor’s front door. He was afraid that the sound of the bell would alarm his neighbor. So he came up with a fix – covering his own ears.

As much as I loved using CPS repair to fix a "bump" on my 70-200 f/2.8 IS USM II, I did notice a few more dust specs inside the lens (when looking through it unmounted) after they opened it up.  Not enough to ever care, but still, not fully dust free.  It happens. 

As for the issue - yeah, its a non-issue.  I dont shoot in dark closets and only maybe if I am shooting the Milky Way at 12,000 ft 100 miles from any city would I ever have to compensate, and I usually AEB anyway.  Exposure Meter only folks!

Tape.  You should see the stuff I work with :)

I am sure somewhere there is a new inventory item on the Canon Repair Supply System -
(1) Roll 20' of Light Absorbing Adhesive Blocker - $100.

I think this is the kind of fix that can wait until my 5D III needs to go in for some other reason..

I don't understand,they fixed with tape the first lot of cameras who had issues(which were sent for repair) or the brand new lot of 5d mark iii after they have realised it has this issues was fixed with tape.

It kind of cracks me up when people talk about/are worried about the resale value of a camera they just bought 37 seconds ago.  I have NEVER based any purchase decision on the future resale value it may have, whether it be a vehicle, a piece of gear or an iPod.  If you want one, buy it. Use it, ENJOY it.

As I'm one of the ones who mentioned I'm concerned/annoyed with it, I'll respond....Loss of value means reduced profits as that money has to come from somewhere. Even for hobbiest, it may make the difference on when/if they upgrade and what else they purchase. If I knew that after a 3 years, a 1dx and a 5d3 would both depreciate only $1000, I'd get the 1dx and everything beyond the $1000 would just be a deposit that I get back. On capital equipment, resale value is important. You wouldn't buy a $300,000 home believing it would only be worth have that in a year, would you?

Canon will always offer this fix for free. So resale value is not an issue since even if these early cameras will be worth less on the used market in a few years you could always "upgrade" for free then.

No, but last time I checked my house wasn't capital equipment. I rather suspect the IRS would be a little miffed if I fully depreciated my house over a 5-year period of tax returns, which is something that's the norm for capital equipment...
