Pretty good ... with a couple of caveats.

«The background blur (shown to the left below) isn't ideal with some rough edges whereas the foreground blur is much smoother.»
Too bad given that for macro the foreground blur is often useless (there's nothing in front of the subject), but it's really good.

On page 1: "it's a fully manual lens thus you will have to live without EXIF data, autofocus and a camera-controlled." <-- "aperture"?

When the object is close to the lens the blur looks perfect to my eyes. |
