80-200/2.8 is the old version of the 70-200VR.
One touch: the same ring controls both zoom and focus. Push and pull on the ring to adjust focal length, twist the ring to focus.
Two touch: two rings, twist one to control focal length, twist the other one to focus.
Disadvantage: uses screwdrive AF. Slower AF, No VR.
Tokina 50-135/2.8 (nikon mount) is no longer in production. The only version still being produced and sold is the Pentax 50-135/2.8 (manufactured by Tokina, I think. Yes lucky Pentaxians). I am look for one myself but can't find. It gives the FOV of about 75-200mm (35mm equiv). It is smaller and lighter than the 70-200VR. But it does not have VR, and it is bigger than the competition. It does not have focus motor also, and depends on the screwdrive AF. But it has a tripod mount on the lens.
The competition is Sigma 50-150. Smaller and lighter than the Tokina, it has a little more reach, but it is soft wide open from 135mm to 150mm. It does not have OS as well, but has HSM. It doesn't come with a tripod mount, and you cannot add one as well.
