Today's questions
Forget the crop

Lori and Matt, Another wonderful show guys,
I have a quick question about Crop vs Magnification. I have a 40D with a 1.6 crop factor, does that mean a 50mm image is cropped to look like a 80mm or the 50mm has zoomed to 80mm?

Depth of fielding

Hi Lori and Matt, question from a new dslr owner. I recently purchased canon xsi with EF 50mm f/1.4 lens. I've noticed that the depth of field I see in the viewfinder seems to be deeper than the resultant images I get. I thought one of the advantages of slr is that you are actually seeing through the lens and hence seeing the images as it will be captured. What am I missing here? I usually shoot with the lens wide open so I don't think it's an issue of not using the dof preview button. Thanks.
