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.

Great app for teaching
Knuckledragger999
Love this app for the visuals. Makes teaching dof much easier. Any chance you could extend field size above 35mm to 120, 4x5, 8x10, etc?
Does exactly what it says.

Nice little app. I'm just getting into photography that doesn't involve the AUTO setting. This will help visualize the effects of the different settings. Nice work.
Nice app, info page biased
tokatoka
First off, nice app by the author. It provides solid information regarding depth of field. However, while reading through the information page I found myself annoyed by the misinformation the author provides regarding quality of Dale cameras based on their sensor size. While sensor size does have certain impacts on a DSLR, it does not specifically define the grade or quality of a DSLR. This is just my pet peeve, and if you ignore the authors bias in the info page, this is a good app. I'm keeping it on my iPad.
Good app.

I like that it is easily manipulated via the touch interface. The ability to drag the background is a nice added touch.
Decent app

This is a very easy to use app, with a simple to use interface. If you are just looking to know the DOF for a particular setup, this is the app for you. I especially liked the slick visual representation of the lens view and the movable background. Objects are roughly to scale, so it gives a pretty good idea of what would be in focus. Unfortunately, this app is missing a measure of the viewable area. It does calculate the angle of view, but if I wanted to do the math, I wouldn't buy this app. Displaying the dimensions of the viewable area at the plane of focus (how tall and wide the plane is) would help in planning shots. It would answer the question, "How far from a person do I need to be to get a full length shot at 85mm on a 35mm sensor?" That isn't something the current app answers. For me, adding this additional calc would make this a 5 star app. If you don't need that, this is already a 5 star app IMHO.
Best tool yet for helping visualize a shot
webslog
Freaking love this app. In 30 seconds it taught me what two years shooting hadn't ... that shooting a long lens wide open means your depth of field is about 3 inches. Sliders and a visual index that gives you an idea of the relative size of things as they'll appear in frame make this the best lens tool I've run across yet. Great for anyone shooting rangefinders as well.
Pretty, but lacking

While the app does a nice job of a physical presentation for the DoF, I was rather put off by the lack of options for the sliders. For instance, the focal length only let's you go to a maximum of 200. The aperture settings had some strange numbers ( 5.7? ). It was also lacking some apertures - for instance, my Nikon D90 has f/10, but that's not available as an option. Finally, there is no place to put in the circle of confusion number, nor does it maintain a camera database. This means that if your camera has a different circle of confusion than the 3 the app lets you choose from, the calculations are skewed. It looks pretty, but other DoF Calcs have more flexibility and better customization.
