Summary: From a Nikon D70 to a D90 to a full frame D3 with a fast lens. I bit the bullet and invested in a Nikon D3 and a Nikon 70 - 200mm f/2 AF -S VR lens. Finally got what I wanted and not a bit sorry. Taking pictures of my Granddaughter playing basketball, indoors without a flash and having the pictures look sharp is really amazing. I never used the Manual mode before on any of the other cameras because I wasn't quit sure how to.
Summary: Just take the word of those who have written extensive positive reviews about this lens. They are all right. It's fast, not as heavy as others make it sound. It's lighter than the VRll version and provides the same IQ.
Summary: I've had this lens for several years, and yes I wish it were smaller and lighter. But recently I compared the results i get with it to my other top Nikon lenses (the 85 mm 1.4, the 14-24 2.8 zoom, etc). And as someone else said in a review, the main problem with this lens is that you won't be satisfied with the other lenses in your bag. I use it on a D700 and a D300, mostly for portraits.
Summary: This is a must have for any photo pro or geek. 70-200mm is a must have. Amazing quality and fast focus. Only downside is the weight and size however this is normal for high quality glass in this range.
Summary: I absolutely love this lens. I have the sister to it, the 24-70mm 2.8 and both are excellent. The only reason I gave it a 3 for size/weight is, of course, because it is big and heavy so it is not for a walk around lens but I still do carry it occasionally as I love the pictures that I get from it when the 24-70 just is not enough.
Summary: I previously owned the first version of this lens and have now upgraded to the VR II. This is hands down one of Nikon's greatest lenses of all times. I shoot a lot of low light Marching Band and Color Guard competitions either at night or in a gym situation, so larger aperture and VR II are a must. This is a great portrait lens too. The larger zoom capabilities help compress background and the bokeh from the lens is exceptional. Yes it's pricey - but worth every penny.
