If you’ve ever browsed the web page of a consumer equipment manufacturer, you’ve probably run into the frustrating experience of trying to figure out what makes one model different from another. I tend to go straight for the product specification pages, but sometimes it’s not enough – they may be missing, incomplete (hello, Fujifilm), incorrect or even intentionally misleading (hello, Samsung), or just plain unreadable. And even when the pertinent data is there, we often find one brand won’t measure using units used by another brand. This is where comparative reviews really shine – but inevitably, group tests don’t cover the precise items you’re considering. One thing that can sometimes help is parametric searches.
