My hottest at the K-5

I bought this lens for macro and portraits. As Macro uneingeschänkt top, although an HSM would be wonderful is the (for me) no real restriction. With the limiter lens focuses quickly enough in the macro area occurs occasionally a Focus on Hunting. When in doubt, is focused manually here anyway.

As a portrait lens, the rating is somewhat disjoint. It's just too sharp for various applications. Please do not portray women who respond to the question reserved to their age. Who does however character portraits, here has found a friend: sharply Aperture 2.8 at f / 16 is still hot and in between sharp, high contrast and subtle in the drawing.

I suspect that there are currently no sharper lens on the K-5, at least this plays in the top 3. The star deduction for only average sharpness at infinity. Presumably focuses the lens slightly beyond infinity, so does the one thing the Sigma service in 1-2 weeks.
