I will be back in the UK for the dive show in Oct and while there was considering upgrading my 50d to a 7d.My question is will I really notice the difference. My main lenses are a 500 f4 and 100-400. How much faster for BIF is the auto focus going to be, is it worth the expense? It will be mostly for the prime and will keep the 50d with the 100-400 attached to save switching back and forth.
