Canon L series 17-40f4   24-70 f2.8   70-200f4  100-400 IS 4.5/5.6  1.4 tele converter

 Canon 100mm 2.8  having sold a Sigma 105mm due to noisey and poor AF  Canon 65mm MP-E 1X5  Macro a true Macro monster but only for the specialist macro nut!! 50mm 1.8 Mk 1 metal mount and as good as the 1.4 IMHO

I have taken a great deal of time in Lens selection to avoid wasting much money and this can pay off in the long term..  Many lens also perform rather less well on full frame sensors and I have been lucky going from the 10D to my 5D as the former did not take EFS types

Lens tried but not rated very high on trial via a great dealer  300mm  L  f4 maybe bad sample 300mm on 100-400 far better Sigma 16-35 ?  very poor 50mm 1.8 MK 11 good quality images but the build quality to poor to live with!  Plastic everywhere!! 

Future lens under consideration 200 L f2.8     Tamron 70-200 f2.8 light and from sample images looks very promising 300 L F2.8  IS

a Macro lens makes a great portrait lens David!!
