I've been amazed at how many new cameras Canon has come out with since I purchased my 40D. I have always been following the "news" on the 5D and now the new 5D MKII. The full-frame debate rages on.
Here's the situation - My 40D with the Sigma lenses I use take excellent photos (gotta love RAW). Post processing in Photoshop is easy and quick. So, please convince me why I should upgrade (I need to know what to tell my bride). Is full-frame really worthwhile?
I've got a good camera, can make poster-sized prints and no complaints.......
