The iPhone 4S with its new and highly regarded backside-illuminated 8-megapixel camera is a powerful piece of technology. Apple has improved the speed of the shutter and the tap-to-focus. It takes seconds to snap a beautiful and crisp photo! Using the tap to focus feature becomes very useful to get the shallow depth of field effect. It'll not match your DSLR but it's quite impressive for a smart phone camera. In some of the images below, you will notice different focus points. Apple went ahead and added the grid, which lets you compose better aligned shots. We've got full 1080p videos and an un-retouched photo gallery testing the iPhone 4S' well equipped back shooter waiting for you right after the break!
