Keep the MM-250 MicroMax Plus from Carson Optical in your pocket, and you'll be able to transform your iPhone 4/4S into a digital microscope at any time. When it's affixed, you can capture close-up photos and video with powerful magnification of 60-100x. To get started, simply attach the provided adapter case to your phone and open up the camera app. Then, snap away! For those times when you're photographing in low-light or fully dark environments, there is a built-in LED light to help you get the perfect shot. A focus knob makes it easy to zoom in to your desired magnification level, or you can just use the zoom function on your phone. All in all the Carson MM-250 MicroMax Plus is an affordable, easy way to achieve high detail for subjects like foliage, flowers and fabrics.
