Free your mind from millimeters and enter the world of degrees. Think of your camera's angle in terms of the actual degrees, instead of what it's "equivalent to." Angle of View makes sense out of millimeters. It tells you the actual angle (in degrees) that your lens gives you. It also tells you how wide across your picture will be at a given distance. Free your mind from the misleading "zoom factor" that camera makers tell you (10x, 20x, 40x, etc.). This app shows you actual "range factor" of any lens/sensor combination, so you can easily compare how wide or telephoto any camera is to any other camera, regardless of how many times of "zoom" the manufacturer says it has.Whether you're a camera buyer looking to analyze a purchasing decision, a camera sales rep wishing to better explain concepts, or a professional photographer setting up for a shoot, this app will become a useful tool in your hands. All new for iOS 7 and redesigned from the ground up, every aspect of Angle of View has been thoughtfully reconsidered and redesigned for the new OS's look and feel. NEW IN 2.0: View five sensor sizes drawn to-scale on your iPhone screen. Each drawn rectangle is a 100% accurate real-life-scale outline of your specified sensor size. If in doubt, measure it with a ruler and see for yourself. Finally see how much smaller "APS" sensor formats are compared with actual APS film. See how similar 4/3" formats are to 110 film. View the cropped area of a DSLR when in video 16:9 mode. Wow your friends and colleagues. :DEverything is fully customizable with a rich database system behind the scenes.This app lets you compare five sensor sizes simultaneously on one display, showing what the millimeters are equivalent to on four other formats relative to your currently selected format. You can swap out other sensor formats from a list of sensor sizes that you can modify. You can see the "range factor" of your sensor size relative to those four other formats.But there's much more. This app appeals to beginners and pros alike. This is also a powerful and advanced FoV calculator / Field of View calculator / AoV calculator for advanced and professional photographers, directors of photography, photo industry professionals, etc. Beginners can use this to make sense out of sensor sizes and see what millimeters actually mean on their lens.
