Lens•Lab is a virtual lens simulation tool for photographers of all skill levels. It graphically illustrates how depth of field and field of view relate to your SLR camera and lenses. Professionals will like how quick and easy it is to get depth of field calculations. Semi-pro photographers will enjoy configuring "what-if?" scenarios for various lenses. Photography beginners will find it to be a great learning tool by exploring the interplay of aperture, focal length, and focal distance in real time. Lens•Lab is more than a great depth of field calculator, it's a lens simulator that can help you explore, see, and intuitively understand how depth of field works with your camera and lenses. Lens•Lab Features: Advanced visual depiction of depth of field with real-time controls: • The background scales from 10 centimeters to 100 meters interactively • Out-of-focus areas are represented as blurred in real-time • Distance labels, angle of view, and other information updates as you touch Easily control aperture, focal length, and focal distance with sliders or touch: • Aperture (from ƒ/0.95 to ƒ/64 in continuous increments) • Focal Length (configurable from 1mm to "very large number") • Focal Distance (from 10cm to 100m) Information overlays are independently configurable: • Hyperfocal Distance • Far Depth of Field • Focal Distance • Near Depth of Field • Total Depth of Field • Vertical Angle of View • Distance Scale • Simulated Blur Sensor size is configurable for: • Full Frame (35mm) • APS-H (1.3x crop factor) • DX (1.5x crop factor) • APS-C (1.6x crop factor) • Four Thirds (2.0x crop factor) Additionally, there are controls for distance units (metric or imperial) and display of Full Frame Equivalent focal length (for cameras with sensors smaller than full frame.) Included is a usage guide that explains all features of the application as well as depth of field in photography. Lens•Lab works with all iPhone, iPod Touch, and iPad models running iOS 8 or newer.

SPECS Includes max aperture, lens mounts, weight, length, close focus, front diameter and more* COVERAGE Overlay a lens’ image circle on your camera sensor to make sure it’s covered. Includes over 200 cameras from Arri, Canon, Red, Sony, Blackmagic, Panasonic and more* LENS MATCH Mix and match spherical, anamorphic, speed boosters and extenders, and even factor in post-production extractions— the lens match tool can handle it all. EQUIVALENT No need to worry about crop factors or sensor sizes, just choose a focal length and a camera and get the Super35 equivalent. Or pick the S35 equivalent length you want and see the lens you’ll need. NETFLIX APPROVAL A game changer for anyone who’s struggled with the complexity of which formats and resolutions meet the Netflix "4K mandate"— especially when shooting in anamorphic. Designed in collaboration with Netflix. DEPTH OF FIELD An easy to use yet comprehensive DOF tool that allows for customizing circle of confusion with presets and manual input. PREVIEW See a simulation of your shot based on lens, camera and distance. Or pinch, zoom and reposition to get the exact frame you want, and see what lens or distance you’ll need for it. AND MORE Filter lenses to see only what fits your specific camera and needs. Save your calculations and return to them later.
