After much agonising over a wide angle lens for my FS7 video and many hires of fast 2.8 lens I didnt even try this before I bought it, it just works, has transformed my run and gun work for video production.
Every wondered about why we need 12mm, well get this incredible beast and YOU will wonder how you managed without it... Not to mention the panorama aspects useful on super 35 as well. At first it took me a while to use It then I discovered by placing items in close focus at f4 and Bokeh the background was simply an amazing effect.... And of course the obvious when you have a small but crowded room it's just magic. Thank you Sony !
