Which lens is a very personal decision. The 100-400mm is good - but for an "L" it isn't great. An excellent lens is the 300mm f/4 L IS - no zoom but with wildlife your lenses never seem to be long...

The Tokina 12-24mm f/4 is a very fine lens. Excellent color and very well built.

Not recommending a particular lens ... but something in the 35-100mm range (zooms in this range can be ok) and f/4 or better (f/1.8 is nice). A low light capable lens is very nice for portrait work.

Your post beat mine by about 60 seconds!

Anyway ... check again on your 200mm lens! The literature says: Focuses from infinity to 19.4 inches (1:1 reproduction ratio). Sounds like life size to me!...

With most landscape shots, wide is good!
