Canon 40D viewfinder query, you can help if you have one ?

Hi Guys

Just powered on my new 40D and the focussing screen was not clipped in right resulting in the 9 red AF points all looking a bit weird in the viewfinder.

So I nervously sorted that, and it all looks okay.. ish, but my question is this. When you activate all 9 red AF points, is there a dull red smudge at the 12 o'clock position right above the top AF point ?
There is on mine, but I'm not sure if this is right or if I still have a problem ?
Thanks in advance

Well I would have taken it back rather than trying to fix it. It is not normal, but it could be just do to a fingerprint you left on the focus screen, try removing it and giving it a clean.

Nope it's not that. I never touched the screen, it looks more like a flaw of some kind, but without someone else to tell me if their 40D has a 12 o'clock red fuzzy circle above the top AF square, I don't know.
Can someone ? anyone help me ?

Definitely no 12o'clock fuzz on mine, but I would not recomend taking the focusing screen out as i had a bug die on mine after about a week and I scratched mine getting it back with just my fingers.
However I was not bothered that much as I wanted to change it for the screen that is lined to help composure. The best 20 I've ever spent, and you get a tool with it to make the job easy.
But I agree with Cambirder, take it bach and say nothing.

Guys, just found this link :

Lots, okay, all of the 40D owners on here have this same "problem" . So looks like it's a feature, rather than a problem ??

Anyone else care to comment ?

Yea there is a slight smudge/reflection or something above the top point on my one. Hadnt even noticed until i actually looked for it.

I only ever use the centre point so had to switch it on but yes mine has the mark. Although when I say mark it is really a reflection because if you tilt the camera a wee bit it virtually diappears.

Its not just the 40D, just checked my 5D and I get that below the 6 O'clock AF point.

The only way you can notice though is to activate all sensors against a dark background. In real use the lights are on for such a short time you just can't see it.
