Thanks again for all replys, you really got me thinking it over again.
First of all, lenses will be used on a full frame. Either 1D or 5D (depending on prices and launch dates, yeah, and rumors...) Btw, sorry for looong posts. But it is helping me helping myself if you understand, kind of like talking to yourself at the shrink I assume...
Let's cut lenses in another way.
Zoo/Kids playing outdoors/kids sports:EF 100-400 L
EF 70-300/4-5.6 L IS
EF 70-200/4 L IS
EF 70-200/2.8 II L IS
EF 300/4 L IS
EF 400/5.6 L
EF 200/2.8 II
PortraitsEF 135/2 L
Sigma 85/1.4
EF 85/1.2 L
EF 50/1.2 L (? or too wide on FF?)
Indoor events/dinners/x-mas/kids in the bath etcSigma 85/1.4
EF 85/1.2 L
EF 50/1.2 L
and
EF 35/1.4 L
daily walkaround / tourist in city X etcEF 24-105/4 L IS
EF 24-70/2.8
The combinations are so many...
Let's put together a new list and see how you can help me improve it.
#3EF 300/4 L IS - outdoor and kids playing and Zoo, I will live with the fact that shots will be missed
EF 24-105/4 L IS - daily walkaround, outdoors and from time to time indoors if light allows
EF 35/1.4 L - indoor in bad light, ie parties, dinners etc
Sigma 85/1.4 - portrait
Suggestions?
- Skip the 300 and go for 70-200 IS 4 or 2.8 ?
- Skip the 300 and go for 100-400 or 400/5.6 instead?
- Skip the 85 AND 35 and get the 50/1.2 instead?
- Skip the sigma and go canon 85/1.2?
Even if I had the money to buy them all (which I don't btw) I wouldn't... I simply want 3-4 lenses that I slowly will learn to use and get most out of. Hopefully they will cover my range and use and allow me to in most cases bring perhaps two lenses but not swap them all the time.
I must admit my experience in the longer focal length are almost none. Here I lack most knowledge. I really can't say whether 200, 300 or 400 would be enough... Yes, I can rent them. And surely will some day, but now I want the tips and ideas from your guys

If you have a 200 mm, how often do you think you should have had a 300 or a 400?
