Hi, I've done a quick search and couldn't really find any info, hence posting.. I have a nikon D50 and the other day wanted to shoot some real close up shots (maybe about 5-10cm away from subject) but the macro mode wouldn't allow me to do this using the 18-55mm kit lens. Then i remembered that maybe I need a macro lens (being new to this of course!), but while i was searching around the net I came across a "Nikon BR-2A", which is very cheap - around £30.. it allows you to screw the kit lens backwards giving you the close up macro functionality that a macro lends would, for a very very cheap alternative. Has anyone used this? And is is worth it? Does it work? How do you use it? You screw this thing onto the camera, and then screw the 18-55 lens (reversed) onto it? Thanks for your help.
