I like the 180, but will upgrade to the 180 2.8 as soon as it is available. The main reason being that it has got the Sigma coating virus .. the plastic coating is peeling off and every time I use it I look like an anemic leopard. More to the point, the bare metal is now exposed to the elements.

No tubes ... too much like hard work if you are hand-holding. The shot is cropped but not actually that much

It's interesting that you say that the Sigma coating virus is effecting your 180.

When I used to work in the labs I had a similar problem in that my Sigma lenses used to 'depaint' very often. It seemed to stop after I left the labs. 
I was never sure if it wasnt the fact that my skin was absorbing reactive chemicals from the lab air and then these were excreted/concentrated in the sweat on my hands.  Could never prove it but it was a thought I had.
