Very poor border performance
I have tried this lens on a full-frame body.
This can be a very nice lens for macro work (although magnification can be an issue) provided you keep the subject more or less in the center of the image. It may be good in low light but also keep your subject in the center.
Pros:
1. Very small working distance, can create some unique perspectives
2. The lens seems to be optimized for close focusing distance
3. Nice warm colors
4. Aperture ring
5. Autofocus
Cons:
1. Border performance almost inexistent, it is unacceptable.
2. Coma is badly corrected, I get blobs of light at the image border coming from silver-like reflecting surfaces.
3. My sample had a centering issue, as the left side of the image was of lesser quality than the right part.
4. Border doesn't sharpen up until f/5.6, f/8
5. Chromatic aberations
I would not recommend this lens unless you use it exclusively for its macro abilities. Otherwise save your money.

Amazing Lens.... Kit - Not so great...
In comparing this lens to the Canon 24mm 1.4 L, I was very surprised. My copy had no forward or back focusing issues. A bit soft wide open; however, very nice at f 2.8 and higher. A quieter focus motor would have been great, small sacrifice for such great images. Beautiful creamy bokeh...Here is what not so great: The filter that came with the package does not have a thread to support the Sigma cap, it fall of. [...]
