Sigma launched a new portion of their website entitled Lens Finder. What it does is asks you to check off a couple of boxes and automatically recommends lenses for your purposes. I’m currently looking through for photojournalism, weddings and portraits.
Give it a try for yourself, and let us know what you think in the comments below. And if you’re confused by the terminology, check this out. Also be sure to look at our coverage of lenses to help you out as well.
