I hate mathematicians ... :-)

What I meant is the Stabilisation doesn't vary whathever the focal distance is. I agree with what you are saying about amplitude and closeness of subject but the VR doesn't vary in effectiveness in relation to the focus lenght.

Unless I am wrong or I totally missed the point.

VR on a i:i, from actual testing is very very good, not worse than on longer f dist.

Ok but VR effectiveness is dependent of the amplitude of the motion
blur. The problem is that motion blur is proportionnal to the focal
length of the lens AND inversely proportional to the distance
camera-subject when the latter is small. Precisely:
motion blur amplitude = k*f(d+f) d
where k is a constant, f is the focal length and d is the distance
between the subject and the nodal point of the lens.

So the question is still unanswered. How does VR perform at 1:1
reproduction ratio?

By the way, which SW are you using to documentate your photos with
the complete exif data?

A script from photoshop.

did you write the script or download it?

Thanks

It is a java script someone did for me.

you can do a search on this forum.

look for print exif post by Joe Colson.

Re: I hate mathematicians ... :-)

Resalut Yves,

VR effectiveness is dependent of only one thing: motion blur amplitude, that is how far from the original position the subject is dancing on the sensor. So if you can get the subject to move the same at 1:1 than at 1:10 you'll get the same effectiveness from the VR. The problem is it is much harder to keep the image still on the sensor at 1:1 than at 1:10 (cf. my previous post). Another way of stating the previous formula is
motion blur amplitude = k* R / d

where k is a constant, R is the reproduction ratio and d the distance from the subject to the nodal point.

Moi j'aime bien les mathematiciens.

Re: D200 and AF-S VR 105 Micro 2.8 G

If one is using this lens for close to 1:1 macro work on insects etc., how cand the VR be of assistance? In my experience for hand held work of this nature where the focal distance is close to the max of 12 in or so, the main problem is vertical movement, not horizontal. Help me understand how VR helps here? Why not simply use a faster shutter speed?

HI Matt, Vr is VR wether you are at long or close range. It is
excellent but cannot produce miracles under1/20 sec. Remember that
105 becones around 160mm in FOV.

If you are saying that you can get a sharp hand-held exposure at 1/20th, at 1:1 magnfication, then I would say that is a miracle!

With my 60 mm micro, I feel like I need to keep it in the 1/120th to 1/200th zone at 1:1 to have any chance of a sharp hand-held image.

Re: D200 and AF-S VR 105 Micro 2.8 G

Bonjour Yves,

I can see that your lens is very sharp but, to my eye, it does not seem to be any sharper than my current Micro Nikor 105 2.8 (non VR) lens. Although, the comparison may be different looking at an actual print.

If you had any experience with the old (non VR) 105 2.8 lens, I would appreciate your comments...

Naturally, the VR option on your new lens is very tempting...

Salutations,

Michel

A faster shutter speed and a good tripod if you have time and it is not windy ...

Salut Michel.

First, the VR is the reason why I went this way, second, the working distance and third, the fantastic results even wide open, surprisingly as sharp as a stopped down to F4 Vr 70-200 in appearance anyways. I can't realyy talk about the sharpness compared to the actual 105 (non VR) closed down but wide open, it is a screamer.

Re: VR effectiveness at macro distances?

Hey Matt, haven't shot a lot of Macro with it yet, I will have to go on a 1:1 test in the near future. I know I can do really good ones at 1/30 for sure ...

Merci Yves...

Switching or not... This is a question I'll have to answer by myself...

Since I got mysellf the R1C1 Kit, I want the best possible accompanying macro lense...

My best regards,

Michel
