The new iPhones have gotten almost as much attention for their cameras as for their larger screens and software updates-

Both the devices, the iPhone 6 and iPhone 6 Plus, have a new sensor on the camera with something called Focus Pixels, an addition that enables significantly faster auto-focusing and more accurate colors. Other features include manual exposure controls, slower and crisper slow motion shooting, video stabilization and higher-resolution panoramas. The iPhone 6 Plus, the bigger of the two phones, also has optical image stabilization for reducing blur and allowing longer exposures in lowlight situations.

As many an amateur photographer has discovered, however, simply owning a better camera doesn’t always produce better shots. So to determine whether the iPhone 6 cameras are a true improvement over their already good predecessors, I shipped my review units to Todd Heisler, a staff photographer at The New York Times.

Mr. Heisler said the size of the iPhone 6 Plus made it too unwieldy to use on a daily basis, so he stuck to testing the iPhone 6. He said he didn’t miss the added features.
