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.
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.
• Fix for crash on plus devices
Ratings and Reviews
No More Guessing on Depth of Field!
Wonderful app. I’ve used it now for several years and I love it. If you want to know FOR SURE what portion of your photo is going to be in focus, this is the best app to see how changes will affect your depth of field.
One great discovery was that by going wider, you get more depth of field. Since many current cameras have high megapixel counts, cropping some of an image off of “the sides” is not an issue.
New improvements = a great app
The new functionality that changes the granularity of your slider movement as you move vertically is very helpful, and mitigates a long-standing issue I had with this app. I just hope that this enhancement is easily discoverable for new users!
Developer Response ,
I've added accuracy to the sliders. If you move your finger vertically while sliding, you can be much more precise in your values.
Great app, great developers.
This app is accurate, easy to use, and generally fun to play around with. I don't use it in the field much, but I do use it to plan out shots ahead of time.
What impresses me more than the app itself is its developers. I was asked for feedback, suggested the sliders could use more precision controls, and boom, here it is on the next update (about a week later). Two thumbs up for these guys. Great app, great team, would recommend to friends.
With Family Sharing set up, up to six family members can use this app.
