halo around the focus point why?

Just a thought - have you tried adjusting the dioptric adjustment knob?

yes

It isn't going to affect the pictures. The light goes out before the shutter fires, and anyhow the mirror's flipped up to form a light-tight seal across the focussing screen. What you're seeing is not unusual - the LED may be a little bright or out-of-position and is difffusing a bit more than might be "ideal". If it really bothers you, see if Canon's willing to fix it, but it doesn't affect functionalty one way or another.

If this is the case, why do they put the eyepiece shutter on the 1-series bodies, Jon? I knew the reason, but if this is true, then it doesn't seem to have a real purpose.

Because light coming in through the eyepiece while you're metering can affect the meter reading. If your face isn't there to block the light, you use the cut-off. It's not concern that the light will affect/fog the image, just throw off the meter reading.

To be honest, if the LED is out of position, it needs fixing. Whether or not it effects the image is irrelevant. Once you've paid a decent amount of money for a product, you're entitled for that product to work as it should.

Could be the screen was knocked out of position too. And that could be user action. Personally, I don't send anything in for service unless it actually affects operation of the gear. Getting it repaired costs too much time and aggravation to be worth it for trivialities.

That's you I guess. If I pay for something, I want it working regardless of "trvialities".
However, if it's self-induced user error, I'll reconsider
