Originally posted by loudbay Hinman, I realize that the shooting environments were anything but controlled, but I scrolled back and forth for quite a while, and I have to say the Sigma is my favorite in both macro and portrait sets. I don't know if I should have said anything as I really would not want to influence your decision. I have a 50mm Sigma macro, and the build quality is excellent, I'm assuming the 100mm is similar. Without having handled the Tamron, I'd have to say it would have to be very nice to edge out the Sigma in this department...

Thank you for the observation and comments. I have formed similar observation after browsing through the two sets of test pictures over the last week.
On the test pictures, Sigma has an edge on the color, especially the background rendering. But I have to say that my testing is totally not controlled and variance happen due to different lighting environment and also the order of my testing similar shots happens on Tamron first followed by Sigma. Also, on the Sigma macros, I did have some adjustment on contrast.
Originally posted by Damn Brit Thank you Gary, I think the Sigma does very well in those scenic shots, very tranquil and scenic photos that remind us there is NO bad macro lens.
