That is a fantastic shot wolfie -really sharp!
I was thinking of buying the Sigma 180 but having read a few reviews and forum discussions I am now leaning more towards the Sima 150. It will still offer a reasonable amount distance from the subject and I have read that it is somewhat sharper than the 180 and offers a greater potential dof.
Having said that, Wolfie's shot shows that the 180 is far from soft. Does anyone have any experience of the two lenses?
My intended subject matter will range from flighty insects, to slow moving whopping great insects to plants and fungi. I'll be using it in the rainforest, so the lighter weight of the 150 is a bonus!
