I've been looking at the lenses again.
I've read what Pekka said about the 70-200 2.8 lens and how having 2.8 at 200m is a great thing. It has great reviews. But it's 3 pounds. Pekka admits he has to bring a monopod with him to use this lens. The 70-200 4-5.6 is half the weight. Is it worth the extra weight?
I normally do NOT carry a monopod with it, but now I know that if I have to shoot about two hours straight I'll get it with me. You can easily hold D30 and 70-200 f/2.8L and it's a very comfortable system to hold - but not for hours. A bigger problem is carrying it around the whole day - even if I'm from a family of champion weightlifters my back gets tired when I carry all the stuff (3 lens + 550EX or two, D30, 4 accus) the whole day. So if you're shoulders are sore and back weak the weight could be an issue and then it's better to buy a lens you will carry and not the one that gets left home.
Quality-wise I can tell you that this lens works for portraits, sports, animals (you can use 1.4x or 2.0x ring, too) and generally anything which needs speed, isolation by DoF and high quality. What I've seen is that every pro has it, and for good reason. The same aperture in both ends of the zoom is very usable (you can see how problematic it can get when using 28-135IS indoors) The price tag is big but I'll pay it gladly (and keep paying...).
I was thinking about using the 2x teleconverter with a long lens. The 70-200 2.8 would become 140-400 5.6. Any thoughts on how that would work? How would it compare with the 100-400 IS lens
one opinion:

1.4x is very popular choice as it does not affect image quality at all.
Has anyone tried a 100mm macro lens?
100mm macros have had very positive reviews and often quoted to be the sharpest lenses (the sharpest one is 135/2.0 so they say). You can find several reviews in http://www.techphoto.org …ks.epl?webobjectoid=21191
