Actually I'm a Canon user!
I use 2 bodies during my sessions, Canon 1DX and 5DmkIII with some Canon lens for each situations.
My preferite studio lens are Canon 70-200 ISII f2,8L, Canon 24-70 II f2,8L, Canon 100IS 2,8L macro and an old Zenitar 16 Fisheye (for strange ultrawide portraits).
For outside works I like to use the wonderful Canon Prime lens:
35L f1,4, 50L f1,2, 85L II f1,2 and 135L f2,0.
In my studio I've some Bowens Gemini 500w heads with a lot of stuffs like Softboxes, umbrellas, backgrounds and othe portable flash heads for light works.
