With the mirrorless cameras coming out, a lot of stuff is about to change.
Terry,
I ended up getting Anne the Nikon J1 in RED to use on the back of the bike. I really liked the fast focus with little noticable lag...but of course I was stationary rotating around to test!

While ordering, I added a new weapon in my Arsenal, the Nikon 24mm f/1.4G ... Amazingly fast. I just need to get better...by accident, I left my D700 in DX mode while using it, Doh!
Also just ordered the FT-1 Adapter so I can put my 70-200 on it! With the 2.7 Crop, that is a 189-540mm f/2.8 lens! I can only dream about the Nikon 200 f/2.0 but being a DINK has it's advantages so maube someday!
Also, have you seen this:
XUME. Makes putting my ND and Polarizer filters on and off a breeze. Pretty strong magnets...but would NOT trust it riding of course. I have broken a "protection" filter when I was in hawaii last Feb. so I do like using them in certain instances. This allows me to take them off right quick.
