Hi Hadock,
As for glass, I use several...
400mm f2.8L (older late 90s era that I acquired from my newspaper days)
300mm f4L
80-200 f2.8L
and a variety of wide angles
I am a bit "old school" as I still prefer Fixed Focal lenses over zooms. Like I said, I grew up (photography wise) in an era, where zooms still had a dicey reputation at best. That said, todays zooms are light years from what they were in the 70s and 80s, it's just that "old habits die hard".
