I have read every review and topic involving the 30D, and it looks like a good improvement that I could definitely use for my strictly hobbyist shooting (prints up to 20x30). I would like the 5D but can not afford it nor quite justify saving a little more for it. I use the EF-S 17-85 IS, 70-200L4 and 50/1.4 with plans to try a macro someday, probably the new 60.
Is there any compelling reason I should not make this move?
