The only downside of picking up a used one is the potential need to send it back to the mothership for rechipping (if you have the 5D3). There's an issue with the IS on the 5D3, and maybe the 1DX.
I have a 5D3 but according to this:
http://www.the-digital-picture.com/News/News-Post.aspx?News=2401
Affected Products
EF200mm f/2L IS USM Lens
EF800mm f/5.6L IS USM Lens
*This phenomenon does not occur with cameras other than the EOS 5D Mark III.
*If the fifth and sixth digit of the six-digit alphanumeric number that is imprinted on the lens mount of the above EF lenses is of any of the following numbers, the lens is affected.
EF200mm f/2L IS USM: If the fifth and sixth digit is 00, 01, or 02.
EF800mm f/5.6L IS USM:If the fifth and sixth digit is 00, 01, 02, 03, 04, 05, or 06.
So as long as I avoid the 00's, 01's and 02's - then I guess I should be alright. Am I right?
