Widest angle, prime affordable low-light lens? (did a search, couldn't find info)
Feb 8, 2011

First - this seems like a question that much come up a lot, but I did a search and couldn't find a thread that really answered my question -

"wides angle prime lens canon site:dpreview.com"

http://www.google.com/search?q=widest+angle+lens+canon+site%3Adpreview.com&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a#sclient=psy&hl=en&client=firefox-a&hs=sYr&rls=org.mozilla:en-US%3Aofficial&source=hp&q=widest+angle+prime+lens+canon+site:dpreview.com&aq=f&aqi=&aql=&oq=&pbx=1&fp=7828c4946c5db268

I'm trying to figure out what lens for a Canon t3i or 60d that's -
1. A prime good for low light
2. As wide angle as possible

3. Relatively affordable - let's say preferably $500 or less, but up to $1k if it would make a difference

Here's the lenses I know of -
28mm f1.8 from Canon, $489
24mm f1.4 from Canon, but it's $1,750 - yikes.
20mm f1.8 from Sigma, $520.

Is the Sigma 20mm (32mm-equivalent) f1.8 the absolute widest angle, f2.0 or better lens anyone knows of? Is there any better lens that I missed? Seems like it's still not quite wide enough. As the 28mm-equivalent on my s95 is still often just-slightly-to-close...
