I have one of these for my Sigma 90/2.8 macro lens if
it is a 52mm filter size. It allows the Sigma to go
from 2:1 to 1:1. It's a 2 element lens so should work
a bit better that single element diopters.

Subject: [OM] Slightly OT, Achromatic Macro Lens
Dear Zs,
I have just found a "SIGMA ACHROMATIC MACRO LENS"
(that's exactly how
its labelled), it appears to be just a close-up
diopter lens, looks
about +2, a bit thicker than my other cheap diopters.
Does anyone know
anything about it, whether it is any good ?
