D200 and AF-S VR 105 Micro 2.8 G

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

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

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?

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.

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 ...

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.

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
