With so many sub-$400 digital cameras flooding the market, it’s starting to feel like a plague of locusts. How do you know which one to buy, given that the quality of these is quite good now? One strategy is to look for a few key features that make a camera stand out from the crowd. Epson’s L-500V has many of the usual specs for a $400 model: a 5-megapixel sensor, a 3X zoom, an SD card slot, a continuous-shooting mode, and a small collection of scene modes. It also has one stand-out feature: the best LCD screen we’ve seen on a digital camera. The big, bright, high-resolution display should make the Epson a hit with families and friends who want to immediately share the fun. While the LCD will wow even the most hardened of professionals, the L-500V’s performance and photo quality don’t follow through on the promise.
