Fuji's XF 100-400mm zoom beats Nikon's 300mm f/4.0 VR prime.

In http://www.bythom.com/nikon-vr.htm Thom Hogan explains why VR should be switched off unless you actually need it. that doesn't address focus speed issues. he's also being misleading. And another explanation http://www.bhphotovideo.com/explora/...ns/image-stabi lization-when-use-it-and-when-turn-it or http://tinyurl.com/pvvubgh more fluff. I think Peter is right (but maybe for the wrong reasons?). he's wrong. vr *helps* autofocus speed because with the image stabilized, the focus points can remain on the same parts of the image. without stabilization, the subject will be bouncing around, making it very difficult for autofocus to track and/or lock. |

That makes the most sense. In fact the only reason the VR/OS was on for the shot I posted was because I neglected to turn it off. VR/OS is typically most beneficial when it comes to gaining some headroom at lower shutter speeds and lower ISO values when shootig handheld. -- Regards, Savageduck |

I find I get better focus tracking without VR. vr and focusing are two independent systems, however, vr actually *helps* focus tracking because the target is stabilized and not moving all over the place. Should be true since the lense, at least Nikons have their own processor: http://www.nikon.com/about/technolog...vr_e/index.htm The autofocus is processed in the camera: http://www.nikon.com/about/technolog.../caf/index.htm Nevertheless there is a short delay after pushing the shutter release fully down while the VR set centres and commences it's new movement. so what? that has nothing to do with focus speed. it's only an initial delay and once stabilized, there aren't any further delays. the autofocus system may also have to rack the lens, so there may be a delay there too. I took Peter to mean a delay between pushing the button and and the camera taking a photograph. I presume he has shutter release set to focus priority. -- Regards, Eric Stevens |

They did on this Mac. no they didn't. one's the entire site and the other is just the one article. today, it happens that the most recent article is the stabilization article, but if you scroll to the bottom on each link, you'll see older articles with the first link but not with the second. as he updates the site with new articles, what you see with the first link will change, while the second one will always be the stabilization article. |
