My Go-to Lens for Low Light
PostedJanuary 2, 2011
Let me first say that I'm not a pro, but my best photos from the past few months have all been with this lens. The highlight of them all was my daughter next to the Christmas tree - great bokeh, natural (if not a bit retro) colors in low light - in fact, I took almost all of my Christmas pictures with this lens and they've turned out great. Also, it's been great at parties. In both cases you have to catch people being relatively still, but that comes with the territory.
I'm using a 7D and I can confirm a few cons that I read from other reviews on another site: it has trouble focusing in very low light; the fit on the body is a bit snug; the mark to line it up with the body has a white dot which should be red. But these are pretty minor cons. Mine doesn't seem to have any front or back-focus issues... And focus matters with an aperture this large. Oh, also, you'll need some steady hands - wish there were an IS version of this!
Anyway - in summary - a great lens for indoor photos and other low-light scenarios. You won't regret it.
