I got a new 50D/EF-S 17-85mm kit on Sunday, but when I was testing how the AF performed in low light conditions, I noticed that whenever the top AF point was illuminated (in both AF point selection and AF point confirmation), there would also be a small patch of red light right above it. I didn't notice it right away in bright light, but when I was shooting in the dark the patch was clearly visible whenever the top AF point was illuminated. I can see it with and without my glasses, whether the camera in in portrait or landscape.
I'm guessing this isn't normal, and that I should get it exchanged? I've never noticed this before playing with several 40D and 50D models. Everything else about this camera is great so far.
Thanks!
