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. ## Key features - Real-time depth of field visualization - Interactive background scaling - Adjustable aperture, focal length, and focal distance - Configurable information overlays - Multiple sensor size options - Metric/imperial unit support ## Chart rankings - #192 in Top Paid · Photo & Video (US App Store) ## Recent user reviews (10 of 42) All indexed reviews: https://appshunter.io/ios/app/lenslab/id431559363/reviews.md ### 4/5 — Charged 3 times *2024-03-06* Hello, I think I was accidentally charged 3 times.. once for 2.99 that went through immediately- once for 3.27 that is pending and once for 7.65 which is also pending. It doesn’t specify where form it just says Apple but they all came through at the same time 12:55-12:57 a.m. I’m not sure how to reach the merchant about this issue, but other than that, helpful app so far! ### 5/5 — Great app for learning *2023-02-09* Love the app, it’s been very instructional. Any hope for medium format sensor support in a future update? ### 4/5 — Great app for teaching *2020-07-27* 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? ### 5/5 — No More Guessing on Depth of Field! *2019-03-12* 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. Awesome! ### 5/5 — New improvements = a great app *2018-04-16* 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. ### 2/5 — Good but for inaccuracies *2018-04-09, version 1.3.2* Depth of field of a lens is determined by focal length, aperture and distance to subject. It is not however dependant upon sensor size. This app changes the depth of field when you select a different size sensor, which is incorrect. The only difference the sensor size has is to the field of view. Fix this please and this could be a great app. ### 1/5 — Does function at all. *2017-01-17* Every time I open the app it crashes the moment I touch my screen. It worked for a few settings then started to crash. Force quit the app yet it continued to crash. I restarted my phone (and to be honest, at that point I was done with this app) and it continued to crash a first tap. This app is less worthless as it cost me three bucks. Don't buy it. **Developer response:** Sorry about that, I discovered a problem with certain devices and have pushed out an update. I hope it fixes the problem for you. ### 5/5 — I've used this for years *2016-09-30* As a photographer and trainer, I'm often asked about lenses and how they work. Sometimes people get it, with just a few sentences. Sometimes it helps to show them instead. This is what I use to show them. Whenever I show the other trainers, they end up getting this too. I don't use it all the time, but when I do, I'm glad that I have it. ### 5/5 — Use this to plan shoots *2015-04-14* This app really helped me realize why I was missing focus so much on a Nikkor 135mm f/2, I hadn't realized that unlike the lenses I'm used to, the DoF at 135mm, and about 10 feet is razor thin unless I dial the lens up to f5.6 or f8. The app now looks great on apple's latest phones too. ### 5/5 — Fast and simple! *2014-04-29* I love this app. I use it for bokeh and macro photography constantly. Saves me from having to doing the math. ## Frequently asked questions about Lens ### What does Lens•Lab do?
