105 VR, VR effect at macro distances tested got my 105 VR a couple days ago, and I have been doing some experiments on the VR effectiveness at macro distances. Nikon of course has said that VR does not work at macro distance, but some posts here had said that it did. Obviously this stuff is extremely hard to rigorously test -- I have no idea if I am above or below average in my hand holding ability, so your results may be very different than mine. The bottom line is that Nikon is right -- it does not really help. I am finding that hand held at 1:1 and 1:2, I need a 1/250th shutter speed to guarantee critical sharpness. At 1/125th all my shots have a bit of motion blur (though not very much). I need to do another round of testing between those two speeds to see where the cutoff is. Testing my 60mm micro, I find that I can get 100% critically sharp shots at 1:1 or 1:2 with 1/125th hand held if I am careful. At 1/100th I get about 40% of them critically sharp, and at 1/80th about 20% are sharp, and below that none. So I guess the smaller degree of magnification with 60mm vs. 105mm makes more difference close up than the VR does. On the other hand, the 105 VR is far more pleasant to actually shoot macro with. The auto focus is way better, and having the extra working distance is tremendously helpful. I have not actually tried to compare image quality, bokeh, etc. yet. When they have enough shutter speed, I would say both are equally sharp. http://forums.dpreview.com/forums/read.asp?forum=1030&message=17935001 |

I did some VR on/off comparisons this morning, but only took one shot at each distance/speed combo, so I am not as confident in the results as I am with the 105 VR on vs. 60 tests (where I did 5 shots of each combo). But what I am seeing is that at 1/100th at 1:1 or 1:2 or 1:3, no visible difference with VR on/off. At 1:5 the VR is definitely sharper, though I would not call it critically sharp, but probably sharp enough. Specifically, with VR on I see motion blur at 100%, but I don't see it at full screen 1920x1200 on my monitor. With VR off I definitely see it even at full screen. But again, since this comparison is based on one exposure at each combo, it does not mean a whole lot. Dropping down to 1/60th, the VR at 1:5 still looks about the same -- motion blur at 100%, but not when reduced to 1920x1200. While the non-VR case has become totally unusable. Also at 1:2 or 1:1 the VR looks slightly better than the VR off at 1/60th, but probably not usable. So I guess the bottom line is not that the VR does nothing at macro distances, but that it does not do nearly as much as switching to a shorter lens does. So, if you already have the old 105 micro, getting the new one will probably get you a bit more hand-holdability, but if you have the 60 micro, it won't. And again, I want to stress that these are just my totally unscientific personal results -- limited sample sizes, and no way to consistently reproduce results. http://forums.dpreview.com/forums/read.asp?forum=1030&message=17936097 |

今天終於有時間試一下 6T 在 Micro 105 VR 上的效果 (學國外一樣以這顆鏡頭為被攝物) (這張是沒加6T之前)  (這張是加了6T之後)  以上都是隨便測試未必是該鏡頭最近的距離!!!

105 VR in AF-C mode I have found something unexpected with the new 105 VR: if I shoot in AF-C, the focus is fast enough to compensate some "subject to lens" motion. In manual focus, I need a shutter speed of about 1/125 to keep excellent sharpness (this is about 1 stop better than with the old 105 AF-D or my Tamron 90, my hands are not standy at all), whereas I still can obtain very sharp shots at 1/60 in autofocus AF-C mode. Here are some samples, all handheld in AF-C mode: ~1:1, 50% crop, 1/60, f11 http://forums.dpreview.com/forums/read.asp?forum=1030&message=17940723 |

you will not be disappointed with this lens. It is funny that I have been one of the first person to receive this lens here in Switzerland, while I am still waiting for my D200... I own (or owned) many macro lenses (the AiS 55 f3.5, the 105 AF-D, the 80-400 VR+ Canon 500D and the Tamron 90 DI) and this new 105 VR is a real winner in my opinion. The possibility to shoot in autofocus mode for macro work is something new for me, even though the CAM900 of my D70 is not really fast. happy macro, http://forums.dpreview.com/forums/read.asp?forum=1030&message=17951708 |

小弟是覺得去比那個 VR on & off 沒什麼作用
因為手持的結果，每個人都不一樣。 |

I often use filters (B+W circular polarizers or UV to protect the lens), but not on the 105 VR. This lens has a strange design: the first optical element has a small diameter (~45mm), it has a 62mm thread and has a full diameter of ~80mm. There is small chance to Hope this helps, http://forums.dpreview.com/forums/read.asp?forum=1030&message=17951655 |

Very nice macros. I find it interesting that some people do not want to think that the 105VR has any advantage in handholding macros over the non-VR version. With the proper technique including the right camera and camera settings, it appears that the 105VR can be handheld for macros with significantly better results than the non-VR version. http://forums.dpreview.com/forums/read.asp?forum=1030&message=17969163 |

The VR definitely does help, though not nearly as much at 1:1 as it does further away. You will certainly get sharper hand held results at low shutter speeds with the VR on than with it off. But my experiments have convinced me that lowering the focal length, and shooting with the 60 micro makes a bigger difference in hand-holdability up close than the VR does.

While you may be able to get something good enough for your purposes at 1/20th, if you can get absolute sharpness at that speed I will be extremely impressed with your hand-holding skills. -- http://forums.dpreview.com/forums/read.asp?forum=1030&message=17970988 |

Check > out some samples at: http://www.pbase.com/nc_bill/nikon_105mm_afs_vr_lens glad to know that I am not the only one to find the AF-C mode effective :) Either your hands are more steady than mine or the AF of the D200 is much faster than the AF of the D70 (and maybe mirror vibrations less pronounced) because the proportion of keepers decreases drastically below 1/60 for me. But I am already really happy with this shutter speed, this is ~1-2 stops faster that what I could manage with the 105 AF-D to keep critical sharpness close to 1:1. Great samples by the way. This lens has great optics, but more impressive is how practical this lens is in the field. happy macro, http://forums.dpreview.com/forums/read.asp?forum=1030&message=17975350 |

到底那時要上市ㄚ,看了真是心動
聽說現在有水貨,價格可能跟公司貨差不多
如果現在買水貨值得嗎?
