Good point about the 300/2.8 IS lens purchase. You have my vote. Someone may ask though what are you thinking the 1D IV needed to make it a break through camera worth a big release. I'd say I'm not Japinese and I don't get paid the big bucks to design cameras but how about a new pro body that has no moving shutter. Thats where DSLR's are headed so why not break it out now!
