Bryan over at The-Digital-Picture has posted his review of the Sigma 150mm f/2.8 EX DG OS HSM Macro lens.
“Sometimes a lens is remarkable for what doesn't jump out at you – or get in your way. I have been using this lens intermittently for just under two years. It has reliably delivered excellent images for me. And that is what I expect from a good lens – one that I pick to use because of its attributes, not because I happen to be reviewing it.
I have not kept-secret my love for macro lenses and the fun that can be had with them. Aside from the OS failure issue, this lens ranks right up with some of my other favorites. The Sigma 150mm f/2.8 EX DG OS HSM Macro Lens is the great-value of long focal length macro lenses.”
