I don't care one rats hind end about what a lens looks like, all I care about is what the IMAGES it makes look like.
The 70-200 VR is a beast of a lens weight-wise, because it is a true f/2.8 zoom. It is lovely in every respect except weight...
I have it and the 55-200 VR, which I use when I want a small, light lens for shooting in broad daylight. Unless you are shooting wide open with the lenses... if you shoot them both at f/11 or so... the image quality is virtually identical.
I know the "lens hounds" here will shudder when I say that, but I own em both and I shoot them both, and it is just plain the way it is...
Having said all this, the 70-200 is VASTLY superior when you are NOT shooting at f/11

... and for about 10 times the money, it should be.
