Canon 5DMkIII’s Backlight Affects Exposure: It’s Official

[News] It’s Official: Canon 5DMkIII’s Backlight Affects Exposure

Canon has issued a product advisory for the 5D MkIII, admitting that the company’s newest addition currently on shelves has some issues exposing correctly while the backlight is on. Canon is working on the issue, but has not yet stated anything specific about possible solutions…
It’s important to note that this issue only happens in low-light situations and that it’s different than a light leak, which is what not-so-uncommonly happens with lenses of various brands. Still, it’s a big issue for some hoping to exploit the camera’s great low-light capabilities; and hopefully Canon will find a solution soon. For a clearer idea of the issue, the video above shows an excellent example of the backlight-exposure problem.
Here’s the full advisory:
