I did a bit of research on this lens when I was looking for my latest macro lens, everything I found pointed to it being a fantastic lens.
Unfortunately it was above my budget, I ended up with a 2nd hand (but like new) Nikon 105vr.
Once I get a couple of other lens purchases out of the way, I might revisit the Sigma 180.
