And no, as much as I loved the old Mk III and didn't experience the AF
problems with it, I found it illogical to keep it because Canon doesn't make
a useable lens system to go with it.  I found the 500/4L IS to be mediocre
at best.  And sadly Canon has yet to make a decent WA lens.  The Mk III is a
sweet camera that got a bad rap because of a small sampling of defective
units. Canon's denial and stall tactics for two months is what blown it out
of proportion.  Amazingly enough most Canon shooters have sold their Mk IIIs
in favor of the D3.  I'm extremely pleased with my D3.  You?
