Got this last night. 28-80mm 3.5-22 Sigma with Macro throughout the zoom. Very early morning shots with very limited light Thoughts so far: 1- It is a heavy lens, by far the heaviest I own. 2- Very smooth and easy to focus 3- I like that the Macro function, (down to 1.5), is available throughout the entire zoom range. The other zooms with Macro function have only been available at one end of the zoom.
