    So, there's what, like 18 versions of the Sigma 70-200 2.8 now?

    I wish they'd just go ahead and make one with OS already. I'd buy one in a heartbeat.

    It does seem that they put one out every six months.

    What is the difference between this one and the old one? (It has the II in its name, but what does it mean?)

    LOL ... they put the decimal point in the wrong place. They say the min focus point is 39.4". That is quite far! They meant 3.94.

    II means version 2. 39.4 looks right. Same as 100cm and it matches up with the 1:5.3 magnification ratio.

    Plus, 3.94" would put the closest focus point inside the lens, considering the lens is more than 5" long.

    You think that is bad, the Nikon 70-200vr has a minimum of 4.9'
    That can be a disadvantage for sure.

    As too the upgrades on the Sigma, I have no other info other than their site.

    OS is what's needed most, Sigma! That is, if you can add OS to the 50-150mm without adding too much weight in the process. Even though the fast aperture mitigates the need for OS, the weight of a large-aperture telephoto zoom adds a lot in terms of hand shake, as Leah pointed out awhile back.

    Weight actually stabilizes. So a moderately havier lens/camera will have less camera shake problems.

    The longer the focal length, the more camera shake gets to be a problem. That is why some people (and probably Leah) confuse that with the weight of a lens... a longer lens is heavier.

    I disagree. A weighty telephoto puts a lot of weight out at a further distance from the camera, so there is less ability to stabilize the camera where it touches the face. Personally that works better for me than stabilizing the underside of the lens with my hand. I agree that a weightier camera adds stability, because it's held at a point closer to one's own center of gravity.
