## What is Depth Of Field Calculator?

Camera list updated to beginning  October 2024. If yours is not listed please email stating which one is missing and I will be happy to add it to the next release.

Ever taken a picture and wished that either more of it had been in focus or the exact reverse and that less had been in focus?  Of course you have I certainly have.  But what settings on your camera give which results and what if you change one of those settings what is the Depth of Field then.  You can calculate it all yourself but it is not easy.  This App takes all of those problems and makes it easy to find the answers.  Just type in the distance to the subject, the focal length being used and the f-stop and the App calculates the near and far distances of acceptable focus and therefore the depth of field.  This is all shown on an easy to understand diagram.  

An example is: You are trying to take a photo of a bee on a flower and all but the bee is to be out of focus. Set the distance of the subject to be 200 mm (20 cm, approx 8 inches), set the f-stop to be f/5.6 and set the focal length at 50 mm.  The App calculates that the depth of field is 3.41 mm (0.3 cm, a small fraction of an inch).  The bee will be partially in focus but bees are more than 3.4 mm across so that depth of field is probably not what you were looking for.  Set the camera to f/22 and now the depth of field is 13.39 mm (1.39 cm or just over half an inch) now this is much closer to what you wanted.  Now maybe the whole of bee is in focus but still all of its surroundings are out of focus.

This App will help you take much better photographs by being able to understand the relationship between the settings on your camera and the depth of field that they produce.  The diagram shown is better than a thousand words of text (as the saying goes).  You can now easily see what effect a change in the settings will make.

The Depth of Field Calculator allows you to quickly calculate the near and far distances of acceptable focus.  Just select the distance you are focused at, the f/stop and the len's focal length and the diagram shows you at what distance acceptable focus starts and at what distance it ends.  You can select to express the focus distance in metres, millimetres, feet and inches.  Unlike other Apps this App does not use picker wheels for the f/stop and focal length values so you can enter whatever values you want.

The only other thing you have to do is select the camera you are using.  The Camera button takes you to a page with the makers of cameras listed to the left.  Select the maker of your camera and then scroll down the list to the model.  Select Save and you are now ready to calculate the correct values.  The calculations work using a value called the Circle of Confusion.  This changes depending on the camera make and model.

If you camera is not listed then email and it will be added.  You can generally find your Circle of Confusion value on the web.  Once you know this value just set it manually in field at the top and Save.

You can manually specify the Circle of Confusion to use.  Just select the field at the top and type in the value required.  Select OK and then select Save.  The user-defined Circle of Confusion will be used.

### 4/5 — Nikon Z8

*2023-11-14, version 1.8.18*

Could you please add the Nikon Z8 to your camera list.

### 3/5 — Before you buy make sure the company is still in business

*2021-08-22, version 1.8.14*

I like the depth of field calculator and would give it five stars. However, the app developer’s site couldn’t be found when I was trying to ask about paying for but not receiving an add on program.

### 5/5 — Lightning fast customer service!

*2021-04-29, version 1.8.13*

After getting the DoF app, I found out that it did not list my primary cameras - Hasselblad H5D-50, Hasselblad H6D-100 and Canon R5! 
Expecting the typical no-reply to a customer service inquiry, I was shocked and delighted to get an email WITHIN DAYS from Jim Chapple saying the cameras had been added. Wow! 😀 
Thank you for top-notch customer service. And by the way, the app is fantastic, too! 
Knowing your DoF on portrait work, especially with medium format and telephoto lenses, is of paramount importance in creating sharper images.

### 5/5 — Clear, fast and accurate

*2020-03-16, version 1.8.10*

Many apps, some costing substantially more, perform this function, however this app is berg fast and clear to use. It also displays the result in a manner that is clearly understandable.

### 5/5 — Nice app—simple, clean, effective

*2019-10-03, version 1.8.5*

I thought about running DOF charts for my new Nikon Z6 using Excel. Then I found this app. For $.99, I saved several hours of work (and got an easier-to-use product). The app is simple, intuitive, yields clear results and is a very handy tool to have no further away than your phone when you’re setting up a shot. Nice job.

### 5/5 — Exceptionally helpful app

*2019-09-21, version 1.8.5*

This is my favorite iPhone photography related app. It eliminated the need for homemade cheat sheets with just a limited number of situations. I recommend it as a particularly instructive guide for those seeking a better understanding of depth of field effects of lens and camera settings.

### 5/5 — Does what it says on the tin

*2019-04-27, version 1.8.4*

Could you please add Mamiya 7 to the camera list.

### 5/5 — Great app

*2019-03-30, version 1.8.3*

Love this app.  It’s simple to use.  Only question I have is.   I have a crop sensor camera so when I enter the focal length do I enter the lenses focal length or the 35 mm equivalent.  For example. Fiji 10-24 I I am shooting at 10mm do I enter 10 or 15mm

### 5/5 — Does what your high-priced camera doesn't

*2018-09-25, version 1.8.1*

Depth of field is vital to a picture's success, but largely overlooked by even the most expensive cameras.  Autofocus will find something in the viewfinder that will be in focus, and with most cameras you can choose what point must me in focus.  But getting that point in focus will only lead to disappointment if something else important is out of focus.  Depth of Field Calculator allows you to specify your camera, and then to enter the distance to your point of interest (generally pretty easy to estimate closely enough), your f/stop aperture, and the focal length of your lens.  Bingo, back comes the closest point that will be in focus and the furthest.  Better yet, if you current settings don't produc a result you need (e.g., a foreground point in focus as well as the horizon), the inexpensive add-in Depth of Field Variants allows you to see how the results change with a tabular range of different distances, or apertures, or lens lengths.  Your first few exercises may take a minute or so.  But surprisingly soon you'll get a feel for things, and can zero in on the result you want very quickly.  No more coming back from a far away vacation with that distant mountain range blurred  in your favorite picture, or your wife's face in the foreground a blob.

### 1/5 — Disappointment

*2017-12-14, version 1.7.0*

If you want to use the single feature of choosing your camera then pay for this. Every other option is an in app purchase. You could just make the app cost what you assume each feature is worth so it’s actually useful. Wasted my money.
