ownership:I own this lens
compared to:Sigma 50mm f2.8

price paid:$110 (ship to India)
positive:Extremely lightweight
Very sharp lens
1:1 magnification with the matched adapter
No CA when stopped down
Beautiful bokeh
negative:Questionable build
Needs the adapter to get to 1:1 magnification
No focus limiter means AF hunts even in good light
CA when not shot wide open.
comment:What can I say ? Its a good macro lens. Its sharp, allows you to get a 1:1 ratio with the adapter and its so light you dont think twice when throwing it into the carry bag. So all in all its a highly recommended lens.

However care must be taken not to drop it. I doubt it will survive a fall on a hard floor !
