This lens expensive but worth the money according to reviewer if you are involved in VR Mode. What does this mean?:?Appreciate your response.

VR is Nikon's answer to the Canon IS system. It is either Vibration Reduction or Image Satiliser. What it does is obviate blurring by altering the shutter speed. I find it very useful for motorsport.

VR/IS/AS allows you to shoot @ a lower shutter speed caused by a camera/lens movement - for this it's very effective and remove the need for a good stand in low-light...

It does not stop the action however - for this you need the higher shutter speed: when a subject is running, swimming, or flying by @ a fast pace for example you can't expect a camera to freeze any motion @ 1/60s!

The equilibrium is reached when your shutter speed exceeds the 1/focal lenght rule -> if you have to shoot at a higher speed anyway (for example 1/300s for a 200mm) to freeze the action then VR becomes redundant... :?

I'm seeking to improve shots at max speed 1/250. I assume from your response that this would be good?

Thanks

FYI - shot @ 1/250s: http://www.stevesforums.com/forums/v...c.php?id=30682

.... and with panning: http://www.stevesforums.com/forums/v...c.php?id=32296
-> (ie @ 1/90 - 1/180s with IS/VR turned OFF for panning effect!) :idea:

I"m shooting basketball shots in gyms. No flash allowed (or wanted) most at F1.8 or 2.0 using Nikon D70; lens 85mm F1.4D trying to get crisp action shot; meaning blurring of hands,etc wanted but otherwise stopped dead crisp. Sports mode found no good for basketball-- too many players in motion for automatic focus to pick up the right one: ergo, have had best results manual,S (center)focus selected and prefocused on a given spot. Meaning I've got nothing until someone/thing hits thatspot. Which is OK. Trying to come with some GREAT shots; otherwise, I could use, as Idid back in college,a 4x5 Speed Graphic and flash.

I appreciate all input very much. Thanks to all who have and are providing!

Well... I guess you have the right lens for the job already!

Canon does have a f/1.2, but so much for DOF hey? :G
You might want to increase the ISO a bit -> otherwise flash is the other option if you need the DOF to capture multiple players...

I can't see how VR can help freezing the fast moving players here unless they stop and pose for you!

Actually prefer the wide aperture so I can blur players other than the one I want to feature. That's why I prefocus on a spot and wait til he/she gets there. The reason I use S focus rather than C which Nikon siuggest for sports. The lens I've been considering zooms to 200mm. From reading the description of trhe lens, I have the idea that with this lens I could shoot from a greater distance without having to woryy about the loss of light. BUT If this were a film camera, I would know that moving the lense furtherR from the film plane would increase the depth of field. But, being new to digital, I don't know if that's true. (?) And I'm not looking for DOF.

Yes - this is still true, but you are also increasing the focal lenght which effectively decreases the DOF!
