I know the obvious differences in that the PK-13 is an extension tube and the BR-2A is a reversing ring.

The lens I am using is an older 50mm AI f1.8 and the camera is a D40. My goal is to get closer to a Macro type picture. Please don't recommend a macro lens. I don't want to spend the money on that and my question ultimately revolves around the fundamental differences between these two items.

It seems that the purpose of the PK-13 is to allow a shorter minimum focusing distance.

The BR-2A will allow very close focusing distances it seems as I tried holding my lens backwards and taking some shots.

One difference that I have picked up on is that with the PK-13, focusing is done via the lens. With the BR-2A, focusing is done by moving closer or farther away.

Any differences that I'm missing?
