(That's when they combine information from the two different focal-length cameras to provide a photo that's better than what you'd get with digital zoom, but not as good as true optical zoom.) Many cameras have or support real zoom lenses which cover a much bigger range than the computational zoom used by some dual-lens phone cameras.Why get a camera when you've got one in your phone? Touchscreen models can allow for greater functionality, but can also be frustrating if the controls and menus are poorly organized. It should provide quick access to the most commonly used functions, and menus should be simply structured, logical and easy to learn. Make sure it fits comfortably in your hand and that it's not so big or heavy that you'll prefer to leave it at home. And last-year's (or even the year before's) models tend to be perfectly fine as well as a lot cheaper. The truth is, one camera rarely beats the rest on all four major criteria - photo quality, performance, features and design. Don't get hung up on making sure you've got the 'best' or newest in a particular class.Sensor size, autofocus system and image-stabilization system are among the features that do. Resolution ('megapixels') doesn't matter unless you're a pro or already understand why.And few specs can be taken at face value. There is no spec that tells you which camera is best.
