Canon 7d or the Canon 5d mark2?

[Miss Molly]

I know this question has more then likely been asked before, but I am upgrading my camera. I have had my canon for a couple of years now but still class myself as a beginner as I have never really taken it if auto, I have decided to go and book into a course and get a new camera as devote more time to taking photos, my favourite subjects to shoot are, animals, landscapes, children and flowers etc..
I just can not decide wether to get a 7d or a 5d mark2, is the mark2 worth the extra money?? I also thought my lenses would fit but after reading a thread on here I am thinking that they won't fit so I will need new lenses..
It is all so confusing.... Help...


edited to say, I reread my post and I should say I do use the camera off the auto settings but not the lenses..
