Re: Manual Focus Nikon Glass


Some first experiences today afternoon with a reversing ring (BR2A) plus a wide angle for extreme macro.

Thee manual of the BR2A has a useful chart showing the magnification for several lenses at infinity when reversed.


Tiny flower bud with a reversed Nikkor 24mm f/2 AI-S by labecoaves, on Flickr

First test of reversing a wide angle for extreme macros. Believe that this flower bud had a diameter of just 4mm. Some dirt particles are easily detected.
D7000 + BR2A reversing ring + 24mm f/2 AI-S + tripod, ISO 500, f/5.6 at 1/200s.
According to the BR2A manual this lens magnifies 2.6x, but as the shot was made in a DX body, the real magnification was 2.6 x 1.5 = 3.9.



Extreme macro with a reversed Nikkor 24mm f/2 at f/16 by labecoaves, on Flickr

Screw detail of the Nikkor 50mm f/1.8 AI-S meter coupling shoe.
Another test of reversing a wide angle for extreme macros.
D7000 + BR2A reversing ring + 24mm f/2 AI-S + tripod, ISO 500, f/16 at 1/2s.
Even at f/16 the DOF is tiny at this magnification.
The exif shows f/2, but is wrong.
This reversed lens magnifies 2.6x, but as the shot was made in a DX body, the real magnification was 2.6 x 1.5 = 3.9.
I think my 50/1.8 needs urgently a "micro cleansing"
