let me rephrase my question forget my skill level, just because I havent chosen one particular area of focus doesn't mean i'm not knowledgeable or lack skill level to take pictures with great composition. I'm looking for a sharp, versatile, fast lens. out of the 2 lenses that i have mentioned which one fits the bill of being sharp, versatile, and fast?
I have both 24-70mm f/2.8 and 70-200mm f/4 IS USM, and 70-200mm f/4 IS USM is sharper and faster.
You can get the 70-200mm now. If your budget is ok, you should get the f/2.8 version. The f/2.8 is much heavier than the f/4 version, but it will help you in low light situation. Also, you need to consider to get the one with IS. In short, you should get 70-200mm f2.8L IS USM (either Mark I or Mark II)
In term of "versatitle", it really depends on what your photoshoot session.
I use my 16-35mm for my landscape work
I use my 24-70mm for my events work
I use my 70-200mm w/ 1.4 extender for wild life (birds, etc..)
I also use my 70-200mm for studio work on models
I use my 50mm f/1.4 and 85mm f/1.2 for portrait work indoor/outdoor
I also use my 85mm f/1.2 for low-light situation
So, when I go out for a shoot, I pack the lens for that shoot.
Prime lenses are usually sharper than zoom lenses, but they are not versatitle
.
One-size-fit-all zoom lens is very versatile, but it is not good in both IQ and low light (not fast: aperture > f/2.8)
