A ~4000mm telescope, equatorial mount and tripod to support it all -- I've always wanted to see/shoot the planets and stars.
A pair of 1DXs and a 1DIV (I think the 1.3x crop would still be better for shooting wildlife). Not 2000
spare batteries, but a few!
The EF 400mm f/2.8L IS II -- once it's finally available! And the 1.4x TC III.
The EF 100mm f/2.8L IS -- no brainer.
The EF 50mm f/1.0L -- gotta see it! And the 50mm f/1.4 II -- if Canon decides to finally
update this lens.
The EF 200mm f/1.8L -- tried it at Adorama; would love to use it in the field.
The 5D III and the EF 200-400mm w/built-in 1.4x TC -- if/when they get released.
The EF 24mm f/1.4L II -- I use the EF 28mm f/1.8 a lot, so I think I would like it.
The EF 14mm f/2.8L II -- I have the original, but the lens flare is annoying.
The TS-E 24mm II -- interested in learning how it works/affects perspective.
Both the 15mm and 8-15mm fisheye lenses. Want to compare the two.
Almost forgot: the new Pixma Pro1 printer. And a couple of years worth of paper and ink.
Finally, a few dozen of the fastest SanDisk 36GB CompactFlash cards (I don't want to potentially
lose 128GB of photos, because a card fails or gets lost!), and a bunch of internal and external 1TB drives to store/backup it all!
