Does the lever on the BR-3 operate the aperture ring? I find it's easier to use the aperture lens when hand-holding then turning an aperture ring.

Also, can you use zooms such as the 35-80mm AF reversed with the BR-2A? This page makes it seem like you can.

Anyone?

Edit: In case anyone ever searches this forum, the 35-80mm does work reversed and you get multiple levels of magnification as you zoom in and out and focus.

Still don't know about the BR-3.
