lol 2.8 because its a macro lens, it was already on the camera and I really didnt have time to change lens or the setup on the camera - the lady concerned was hatching whatever I did.
As for 5 grand it didnt cost that - far from it - the 1DmkIIIs was that price when they were first released and that was nearly 5 years ago. Mine is the 1D Mk III and I brought it second hand - sadly!
