I'm returning my Nikon 70-300VR

At first I thought this lens was the best thing since automobile GPS but I am extremely disappointed. On a tripod with the VR turned off, nothing was sharp at full crop. I took the same picture with a different lens, same focal length and the image was sharp. Sure, it can help with hand movement but I get the feeling there is so much going on inside this lens that it's impossible to get the optics right. It's going back tomorrow. So...you bought a VR lens so that you could turn it off on a tripod? Perhaps your test should be handholding both lenses under the conditions that lens was built for. -- Images (Plus Snaps & Grabs) by MarkČ at: www.pbase.com/markuson |

There are many lenses that are imperfect, yet they serve a special purpose. The special purpose of VR lenses at the consumer level is primarily for hand-held shooting. If that is the purpose, then I think the test should involve that. I agree that basic sharpness is important, but in the case of hand-holding, other blur-factors can become even more immportant. How does the lens stack up against it's non-IS counterpart when hand held? It's quite possible that results will still be better with that IS lens. It all depends on the intended use. Keep it...send it back...but at least remember what the lens was designed to deal with. If you want absolute sharpness, then pay for professional glass. The 70-300 isn't that. -- Images (Plus Snaps & Grabs) by MarkČ at: www.pbase.com/markuson |

Which is a pain in the butt, because I was thinking of buying one. :-(

It turns out much of the problem was mirror shake, which for some reason this lens is more sensitive to. When I locked the mirror, the image was fine. What Nikon DSLR has mirror lockup? Do you mean you used the self timer? |

Update from original poster: It turns out much of the problem was mirror shake, which for some reason this lens is more sensitive to. When I locked the mirror, the image was fine. I will keep the lens. The VR is worth it. If the mirror made that big a difference I wonder about your tripod setup and release method. I hang my gear on the tripod and use a shutter release. I don't know why a particular lens would be more sensitive at at given focal length. |

I don't know why a particular lens would be more sensitive at at given focal length. It's not the tripod or the technique. Other lenses do not do it at the same focal length. I have the feeling the mirror shakes the lens elements in addition to the camera body and no tripod can help that. Does the VR being on in this test situation mitigate the mirror slap? -- John McWilliams |

Before giving up on this lens, exchange it for the same lens. BTW, see my http://www.ferrario.com/ruether/slemn.html for more on this. -- David Ruether http://www.ferrario.com/ruether |

What Nikon DSLR has mirror lockup? Do you mean you used the self timer? The D200 certainly does (it also has a 0.4s delay if you prefer it, eg if you don't have a remote release handy), and I think so do the D2H and D2X [assuming you consider smaller than full-frame cameras worthy of the name "DSLR" ] |
