the 100mm f2.8 doesnt have the IS or the L designation as its stable mate, but im wondering if the L is really worth the extra $500...
i dont own either of them and probably dont need to. my friend just got a 5D3 and wants one in the worst way. he just cant decide the same question...
personally id rather have the L just because im a Canon snob but $500 is a chunk of change...
It is mint, as new, always had a UV fitted & was under 12 months old so couldn't go wrong really.
