The original Tilt Calculator, on your favorite AppStore since 2012!

A tilt-shift lens allows to move the plane of focus at will within the boundaries of the lens' settings. Tilt Calculator determines the best settings of your tilt-shift lens so you can adjust it accurately, and get the focus precisely where you want to! No need to carry printed charts, tables etc. Say also goodbye to blindly fiddling with the lens tilt. Get the app, bring your iPhone, input your settings and you're all set! Tilt Calculator not only quickly puts you in control of your lens, it also helps you understand precisely what is happening.

Tilt Calculator provides you with a lot of additional information besides the lens tilt such as plane of focus, wedge of focus, recommended settings for landscape photos etc. to make sure you get exactly what you want :)

The Tilt Calculator app was designed such that it can be used reliably with a single finger. It is a bespoke tool made by a passionate amateur photographer, yours truly, based on actual needs seen in the field by many photographers and me :). It is used by hundreds of photographers around the World.

Tilt Calculator contains simple explanations of the plane and wedge of focus, the hinge line etc. and how these change with the lens tilt and the focusing distance, so you know what affects what. On-screen information, Interactive "blueprints" remind and illustrate the basics.

Importantly, the app also takes into account your camera tilt, for it is an important part of a photographic composition e.g. in landscape photography. The camera tilt can be set manually or measured automatically.

Tilt Calculator comes ready with many adjustable sensor/film formats and focal lengths so it fits with your photographic equipments.

Tilt Calculator also contains a spirit level: accessible from the main screen with a 2-finger tap, the spirit level allows you to accurately adjust the head of your tripod to a level position prior to installing your camera. (Exit the spirit level using a 2-finger tap as well).

We welcome feedback and suggestions! You can send in-app email directly :) And of course, we welcome reviews in the AppStore :)

What's New

Version 4.0

New PRO and EASY modes:
- PRO mode allows you to set the hinge line distance as you see fit (as the app was operating prior v4.0)
- EASY mode sets the hinge line distance automatically. All you need to worry about is the vertical distance between the lens and the ground - the app does the rest, regardless whether the camera is tilted or not, regardless whether the ground is tilted or not. EASY mode is set as default in the App - EASY makes it easy :)

Misc. edits for better clarity.

Ratings and Reviews

Thank you!!!


this app is absolutely awesome. the graphics allow you to understand an play with the tilt, and the inputs & measurement function is extremely useful when photographing. maybe i will be skilled enough one day to not need this, but especially considering the cost of a TS lens, buying this app is a good idea.

Save your money!


Rediculous. Can't tell measurement units (says everything is inches; I don't think so), negative "hinge line" (height of camera off the ground)? What does that mean? Your tripod is in a hole???
Software is just useless. Wish I could get my $$ back...

Excellent Adjunct to using tilt shift camera lenses

Satisfied Seattle user

I have just started to explore Canon tilt shift lenses and find this calculator invaluable in determing degree of tilting needed to achieve desired focus. Its results match those printed in various tables when the camera itself is level. This calculator really comes into its own when you tilt the camera itself in addition to tilting the lens, for instance in using a 90 mm T-S lens for macro shots. There is an animated help section in the app that shows you visually what happens when you adjust various parameters. As for the previous reviewer's criticism, the distance from the camera to the hinge line can be set in inches or centimeters - you select the units on the set-up screen where you specify the sensor (or film) size and the focal length of the T-S lens. The positive or negative values the previous reviewer lambasted are referenced from the camera itself, which presumably is on a tripod or even hand held some distance above the ground. For a camera on a 60 inch tripod used for landscape photos, for instance, the hinge line would be ground level, so the distance from the camera to the hinge line would be -60 inches. This becomes even more important if the plane of focus is vertical (eg a long wall extending into the distance) rather than horizontal along the ground. Similarly, the degree of tilt is measured in reference to the camera so tilt downward is negative (if camera is in landscape orientation) and tilt upward is positive. There is a short learning curve to using this calculator, as there is with T-S lenses, and I would suggest users review the help/tutorial section of the app first to learn its conventions, which do make sense for an app that can be used for all manner if tilt- shift lenses, including perhaps large format (but I have no experience with the latter). All in all, an outstanding app for doing the calculations needed to reduce trial and error in using T-S lenses. I have no connection with the app itself, just am a satisfied user.
