Here it is.
Canon find the way of doing nothing.
The say if you think there is something wrong with your camera canon will check it for free starting in mid may.
By that time you forgot all this.
I will say send a clear message to canon returning your camara like i did and buy another one when they fix the design.
Serious!!! Man, ever since the invention of in-camera meters they have never been 100% accurate. Even if this supposed light leak problem is fixed the meter still won't be 100% accurate. That's why testing is done to see what the meter does and work with it form there. Also why hand held light meters were the norm when it was just film. With digital it's even easier to work with by learning how to read your histograms. Never trust the in-camera meter unless you've tested it, know it's quirks, and have calibrated it based on a reliable hand held meter. It's really not a problem, as reliable sources (lens rental guy and Canon) have stated. I'd trust them over some Joe programmer on the internet ranting about nothing. It would be awesome if everything manufactured was bug free, but that's not gonna happen. No matter what product it is, there is always some minor issue. It's the nature of the beast when dealing with sophisticated electronics. Stop worrying and just shoot and have fun!
