Focusing Screen Question

[calicokat]

Just got the crop lines focusing screens for the 1DsMII, one is for a 4x4 format, the other for a 4x5 format. I am pretty sure which is which, but wanted some confirmation. Which is which, I included the link with the pics of the screens. What do you all think, which is which. I think the one on the left is the 4x4 and the one on the right is the 4x5. But if the 4x4 is a square, wouldn't it look more like #2, but a 4x5 crop only takes a bit off the sides so I am thinking the 4x5 is #2, now you see the dilema :eek:

Thank you, I think it is too. Does anyone else have these screens or experience with them

Ok, I think I solved the problem. Took a 8x10 photo sheet and framed it in the viewfinder and voila, the screen on the right is the 8x10 crop :)
