Well, i had to get another 40D after the other one's top lcd crapped out.

This one seems absolutely fine, to my relief, but the bad luck strikes again.

The focus screen is wonky!!! If i line up a horizon with the horizontal 3 points it is skewed. If i use the top and bottom edges of the screen to line up, its fine, and shooting a box on a flat table is fine. So it's not the sensor that is wonky.

What are my options for the focus screen. I've tried opening the latch and wiggling it then closing it again, but it seems like the actual print on the glass is skewed, or could it be the holder.

Would any of this bother anyone else, or am i being ultra picky?

i've never even heard of that before. never even thought to try that sort of test. what made you do it ? did some of your shots turn out skewed ?

In picture 3 if you look in the view finder is the box on an angle. It is hard to tell on the focus chart as you would need to be lined up perfectly to tell anything

yeah, i've never tested for this before either. Just noticed that all my shots were coming out skewy.

The local camera shop had one in so i've just been down and back and i'm now on my 3rd:eek:

This one seems a bit better although if you were really nitpicking it is slightly the other way noe:rolleyes:

In the third pick the box was square to the edge of the viewfinder, it was the horizontal focus points that i normally line up my horizons with that was throwing me off.

Anyway the guy in the shop had a look and agreed with me that it was off.
