BR-6 and AR-2 or AR-3

[max_bian]

<p>Do I need to get the AR-2 or the AR-3 for Nikon BR-6 Auto Diaphragm Ring? I want to be able to a G-lens for Macro in the reversed configuration.</p>

<p>They seem to have quite different connectors at the end.</p>

<p>Thanks.</p>

<p>You need the AR-3 which has male threads.</p>

<p>Max,<br>

Surely with a G lens you won't have any control over the lens aperture will you?</p>

<p>If the rear element of the lens you want to use is not very big, Nikon F to micro four-thirds mount adapter from Novoflex may suit your need. The adapter has a nice matallic blue ring (well, the color doesn't necessarily have to do with the function, like Napoleon's yellow suspenders) to enable the manual aperture control of G type Nikkor lenses. There is no way to know the exact aperture value, though.</p>

<p>The aperture on a G lens reverse mounted on a BR-6 can be controlled with the cable. By pushing the cable down and locking it, you can adjust and set the aperture to any size opening.</p>

<p>If you haven't purchased any of these items yet, don't. For the same price category you can purchase a Micro-Nikkor 55mm lens and have the correct equipment and find it much easer to use. <br>

While reversing a lens will allow it to focus up close, it was not designed to work this way and won't provide the best image quality. Since G lens have no local aperture control you would find both focusing and exposure setting a pain.</p>

<p>Thanks for the answers.<br>

The 35mm f/1.8G reversed can give me 1.75X magnification. The image quality looks decent. So I thought it may be more usable to add an aperture control. <br>

Looks like BR-6 with Ar-3 will allow me to set the aperture.</p>
