Review: Fotodiox Macro Extension Tube

I've never done much macro (extreme close-up) shooting, but I still think it's pretty cool.  When Fotodiox offered to send me an adapter that would make any of my lenses into macro lenses, I jumped at the chance.  At only $10 (for the Sony NEX version), it's a steal. It's definitely not perfect, but the low price more than compensates for the hoops you may have to jump through to get it to work properly.

PROS
Cheap
Lightweight
gives you uber-cool extreme close-up video

CONS
is only effective with manual lenses (no electronic pass-through)
adds weird tilt to camera (when used with Fotodiox lens adapter with tripod mount)
need long lens for practical use (only a con if you don't have one)
