I have written a short experience I had with this amazing lens
It can be seen here

There are always people asking wat is a good portrait lens..
But a wide angle lens can be a great portrait lens too

And this lens have proved that it works great

this image was taken with the lens at 8 mm f2.8
again.. distortion is well controlled
and I love the fact that its a f2.8 lens.. so it helps to get images even in a badly lit place..

image is taken at 9 mm.. it was cropped slightly.

image shot at 8 mm

Will be posting more images with this lens soon.. so look out for it..
