Excerpt: I'd been looking to buy this lens for a couple of years and finally got around to it. I work with video and I needed a fast, wide lens so I could film in poorly lit places and on the streets at night. This lens is fantastic and one of the smartest purchases I ever made.<br />But it goes a little further than I imagined: it also works great for macro (both photo and video).
Pros: Great for Video, Strong Construction, Very good in low light
Excerpt: Compre la lente para usarla en diafragma 1.8 y solo puedo usarla en 4.0 que es donde me salen las fotos nítidas. Si es un tema de compatibilidad tendrían que haberme explicado al momento de la compra ya que tengo una Alfa 33 y una Alfa 65 que se las compre a ustedes y en ambas me hace el mismo defecto. Aguardo respuesta. Saludos.
Summary: Fantastic lens. At 20mm the f/1.8 is just incredible to be able to be so close up in such low light with really terrific results. I use it almost exclusively for video and the manual focus works incredibly well.
Summary: I bought this lens because lately I've been sort of in love with FFL lenses. I wanted something wider than my 35mm to get some nice indoor shots of churches, temples, architectural items, just because I travel a lot and I like visiting a lot of cultural spots, most of them being buildings with history, etc. The great thing is that the lens is very wide angled, and has amazing low light performance. I do not regret one bit paying $629 for this.
Excerpt: I purchased this lens to shoot with it at live music events in dark venues with stage lighting and in very fast-paced environments, unfortunately this lens didn't work out so well for me because in those very demanding situations it's auto focus performance left much to be desired as it often struggled to achieve focus.

Summary: Listprice is 700$. You shouldnt pay more than half of that. For the my price it is a funny little lens. Use on starry nights or when you want to do landscape with something up close. Compared to Canon 10-22 it is soft until 8,0 but the Canon lacks 1,8 - 2,8. Recommendet if you find it for the right price and is not decentered.
Pros: Focus just front of the lens. Only f1,8 20 mm in the world!
Excerpt: I purchased this lens to shoot stars due to its speed and wide angle and ignored most reviews thinking that people were just being picky and over critical, after all, these were just the specs I needed! Alas, I was terribly disappointed by this Sigma lens. Wide open this lens is useless for night shooting as the stars, even in shorter exposures blur and flare in a halo anywhere outside of the very center.
