I just receive word from Adorama
that all of their Canon EOS 5D Mark III body
preorders will be filled today with extras available.
The Canon EOS 5D Mark III bodies
are not yet showing as in stock, but again, I'm told that extras are available - just place a preorder. How many extras are available is of course a good question - and I'll let you know that answer when I receive it.
Don't forget that the 5D III qualifies for the Canon doubled lens and flash rebates. Update: Adorama
now has both the Canon EOS 5D body-only and the with-lens kit
