hehehe, if only. Does this include not-yet-existing items (but announced)? If so, my list is:
1DX, 1D4, 5D2, 7D. Probably multiples. I am curious to test them myself for one thing. Also I doubt I'd want to carry the 1D bodies much.
500mm f/4L mark II
200-400 f/4 1.4x
180mm L macro
70-200 f/2.8 II
70-200 f/4 (landscapes, less weight)
Tokina 11-16 f/2.8
50mm f/1.4 (I'm more interested in compactness than an extra half-stop of speed)
for comparison... Olympus 21mm f/3.5, Nikon AI-S 20mm f/2.8
Samyang 14mm f/2.8
out of curiousity... 8-15 fisheye
voigtlander 125mm f/2.5 APO macro (maybe two, just in case one ever breaks)
another copy of my wonderful Canon 100mm f/2.8 macro (USM)
just for fun, to compare them, because I love closeups... a Leica 100mm macro, ZE 100mm macro, sigma 150mm APO macro, Tamron 90mm macro, Kiron 105mm macro. Various adapters as needed.
Flashes... at least 3.
More light stands, diffusers, umbrellas, reflectors
Sturdy copy stand and lighting setup to use my bellows and micro lens. I'd look for some Nikon and Olympus bellows micros to compare against my Minolta 12.5mm micro
I doubt that I hit 100k even with all that. If so, I'd double up a few things in case they are discontinued.
