Simple DoF Calculator App Reviews

Great app. Excelent excelent app

Best DoF Calculator that I've found. I like how quick you can make adjustments to awe the results. I only wish the answers were in feet & inches (not just feet with a decimal).

Will use this for my 16mm cinematography class. Very easy.. Quite nice! Simple, straight-forward.

Best of the bunch. As mentioned by another reviewer it needs a bit more of an expanded range. I used it for some macro photography and it worked great for my 150mm prime at f/22.

MATH IS CORRECT, if you understand.. At first glance i thought the math of this calculator was off. Why was it giving smaller DOF measurements for cameras with smaller sensors? It should be the opposite. But then i realized the difference between focal length and angle of view. If you take two cameras with the same 50mm lens, one camera w/ a full frame 35mm sensor and the other with a 1.5x crop sensor, the DOF of the 1.5x crop camera will actually be slightly smaller. The reason is that even though the camera has a smaller sensor (and therefore greater DOF) that lens is now behaving like a 75mm lens. So it is providing the angle of view and the DOF of a 75mm lens on a full frame body. If you want to compare the same angle of view between the two cameras then you need to compensate for the crop factor. In other words a full frame body w/ a 75mm lens will have shallower DOF then a 1.5x crop body w/ a 50mm lens and both cameras will have the same angle of view.

Very well done, minor usability quibbles. As a long-time user of DOFMaster on the Palm and recent switch to iPhone, I downloaded Simple DoF Calculator based on the high reviews. Simple DoF Calculator makes data entry fast and simple because all data entry is done on one 3-slider wheel. DOF calculations are identical between the two (as they should be). Couldn't imagine a simpler and more straightforward way to design this app. It does exactly what it should and is attractive and very easy to use. Two minor quibbles: 1) The focus (distance) and focal length (lens) choices should run in consistent geometric progressions just like real cameras. It's odd to see choices of 90, 95, 100, then 101, 102, 103, ... for focal length, and a 1 mm precision at 100 mm is not really useful and makes it harder to find the right setting. Instead, have every choice be, for example, 5% or 20% bigger than the last one depending on whether fast spin mode is selected. Similar for f/stop. 2) Even though it is likely rarely needed (maybe never), it would be nice to have the focus setting go beyond 100 feet.

Excellent program with no in-app purchases. Easy to use and does what it is supposed to do. Even offers no cost updates for new cameras. No attempt to sell me anything else. Nice.

Does what you need it to. Simple and effective

Very well thought out app. This is a very easy to use app that makes calculating depth of field quick. My only suggestion to improve the program is that it would be nice if the depth of field could be set to display inches or feet. Worth the money!!!

A good start.. It's a nice little app that could be improved slightly. I really wish it had a camera bag function to store the lenses that you use allot and there aperture limits. Worth a dollar though, it's built better than allot of other apps.

Great App!. Very easy to use. Just what I was looking for. Thanks!

Easy to use!!!. Great little tool. Much easier to use than other apps that use a slider or text entry. Well worth a few bucks!

Explain the math.... I'm no genius but shouldn't you get shallower depth of field the larger the film plane? I like the interface. But if the math is wrong what's the point. I think I may have just wasted a buck.

Superb. Tried a number of DoF calculators. Most suffer from inconvenient method to enter data: focal length, distance, f/stop; you have to erase current value, then use the keyboard to enter new values. So slow in practice. Many offer long lists of camera models to choose from; kinda nice but the DoF calulation mostly related to sensor size, not camera model. Likely you only need to do this once, though. Many cameras models use the same or equivilent sensor. And lastly, the DoF formula is based on a specific value for the circle of confusion (CoC). (In fact when you pick a camera from the list, you are really selecting the CoC that will be used in the DoF calulation.) Many photographers prefer to choose a value that is somewhat smaller than commonly specified; this has the effect of suggesting a smaller f/stop and larger DoF. Here's where this app shines: it uses scroll wheels to enter data. This makes it incredibly easy to fine tune the DoF values when making compositional changes to focal length using a zoom lens. And in addition to the common list of camera models, you can simply select the CoC you want to use. It also support two camera model (or CoC settings) if you have cameras with different sensors. Whether you decide to use a Camera Model or select a CoC, this app is fast to use and easy to read DoF values. The fact that it's free is amazing!

Needs another number.... With focus at the hyperfocal distance, depth of field extends from 1/2 the hyperfocal distance to infinity. Yes, I can do the math in my head, but I'd like to see that number on the screen too. Maybe to the left of the hyperfocal distance number? Thanks for the nice app!

Lacking continued development. Was a very good app, with both graphical and numeric feedback. Depiction of DoF is excellent. But lack of newer camera inclusion and silence from developers suggests moving on. A good implementation that’s not keeping up.

Developer does not respond. This has been my go to app for DoF but I recently bought an APS-C camera and asked the developer to include it in supported brands some time ago. A reply, either way, would have resulted in 5 rather than 4 stars.

Best of all the DOF apps. I've tried a slew of these apps, and this takes the cake in terms of layout and ease of use. The slider wheels are very straightforward to use and the info is well displayed. I'm not sure what one reviewer was complaining about when he said they won't give you the distances in inches. It will say something like 1' 5.47". But converting 0.47 inches into fractions would be absurd. Also of great importance, the info yielded does seem to be correct, which I've confirmed by doing photo tests and also cross referencing it with other apps and websites. Interestingly, they don't all come up with *exactly* the same results, but they're close. The reason for this, and for many other questions about this (and other) app's accuracy, is that depth of field is a very subjective measure. It relies on a determination of what "acceptably sharp" means, and also varies depending on how much you enlarge your photo. That is essentially what crop sensors do, which is why the same 50 mm lens on a full frame will have a different DOF than it will on a crop sensor. Completely separate from that is the question of field of view. You can try and figure it all out--I have, but even I still get confused sometimes--or you can just rely on this app. Because it's right. My only other suggestion for an app in this category is called Lens Lab. It has a slightly different take on how to display the info. Kinda neat, but in terms of actual usability, I still prefer this one.

Developer needs to update. The new cameras are not included. Its time to update.

Best DOF app money can buy. Actually at the price offered I consider it free. The calculations are perfect, the interface is great. I like the side by side cameras feature, comes in handy when I have more than one camera on a shooting session.

Easy to use!. Nicely designed app - simple, easy to use. I suggest rounding measurements to the nearest tenth of an inch. There are just too many numbers with hundredth of an inch display. Besides, I don't think DoF accuracy to the nearest hundredth of an inch is really necessary.

Great!. Really nice app. Looks good and it's easy to use. Thanks for the update!

Canon. do not have the Canon EOS RP camera in the list. 😔

Outstanding. Fast and efficient apps, worked just like advertised - The last entry retention feature is also nice Wished it had a manual feet/meter overide button...

Very poor. I am an experienced award winning photographer and bought this app. I use a Nikon D 800. There are no instructions on use with this app , and little useable information. It’s a complete waste of $1.99.

Canon R5 Mark II. The app is not up-to-date for Canon R5 Mark II cameras. Do not buy if that is what you’re looking for at this time.

Works great!. It's one of the best I've tried so far. Good job!

OK. A bit awkward and a little hard to view. OK for $1.99 but probably not worth more. TrueDoF Pro is better but more expensive.

Nice app. Very clean user interface, excellent selection of cameras, but doesn’t allow user to adjust circle of confusion diameter or reproduction ratio. What’s worse, I can’t even find their assumptions about these parameters. Excellent for beginners, not so much for pros.

Excellent app. I tried some other DoF apps but none compare to the slick interface and ease of use of this one. Well worth the couple bucks.

Great App. Simple to use and understand...a great help when trying to achieve maximum dof

Works well. Works well. Easy to use

Good app but.... it would be nice to have the option to display the DOF in inches rather than fractions of a foot once it is under 6 inches or so. I just have a hard time getting my head around .05 feet. Of course this is a very shallow DOF, but the whole point of using an app like this is to be able to calculate just how shallow.

Needs improvements. Not very useful with long focal lenses. The developer needs to accept the fact that this app for the most part will be used for manual adjustments. For example, I have a manual zoom lens (non-TTL) that covers focal lengths from 650 through 1300. There is no way to calculate a precise hyperfocal plane because the app doesn't cover that range smoothly. The app should cover long ranges in non discrete fashion, because long glass has a very shallow depth of field requiring precise calculations. Forced extrapolations or interpolations just defeat its purpose.

Outstanding Tool. I wish I had found this app years ago, it would have helped me turn so so projects into great projects. What I like best is that it's what I need and without all the clutter.

Simple and convenient. Much better than using a web based calculator, and way better than other abandoned DOF calculators in the App Store. Wish it was possible to add custom cameras (or at least rename the camera choices to match your kit), and the text in the "road" could be larger and easier to read in a hurry, but otherwise a perfect app.

Best dof app. Fastest to use. The 4 number wheels make it very easy to quickly put in numbers. I find the other apps with sliders I could never get the sliders right where I wanted them. This one has the best graphical design that helps visualize the dof numbers it spits out. If they added calculations for lens tilt that would be nice.

Straightforward. Easy to use and accurate. There are more complex ones out there, but they give the same answer, only to more decimal places (try setting your focus to 19.37 feet, I challenge you!). Definitely my go-to tool.

I would love. I would love for them to add the Sony a6700 ! I have the app but it’s missing would make it raise otherwise

Takes the guess work out of the picture. This is a fantastic app; it is well designed and easy to use. I love that you can set and keep up to four cameras with their own different settings, really handy if you have more that one, otherwise you would have to scroll through hundreds of them in its database to choose a different one. The last used settings are retained even if you quit the app. As per how accurate it is, I haven’t done any thorough testing yet, but it seems to be pretty good. One request: please add a setting for optionally displaying 1/3, 1/2, or full f-stops - less scrolling is always better, especially if you don’t have to. Thank you.

Is not working. Every time I opened it freeze after a couple of seconds and the it closed.

Always hit DOF head on!. Works as advertised! Invaluable DOF tool for photo noobies and enthusiasts. Since I always have my phone with me, the Simple DoF Calculator is always available.

Fractions of a foot instead of inches. The inability of this app to translate DOF into inches rather than fractions of a foot made me uninstall it right away and revert to PhotoCalc. Too bad, I would have really liked to give a better review to this app that tries to offer a simple tool in an elegant graphical fashion but fails due to complete laziness on the part of the developer. When I'm trying to calculate DOF, I need a quick set of measurements, down to smallest increments, rather than being left with mental gymnastics.

No Support for D7000. Unfortunately the Nikon D7000 is not supported. It is not in the selection list of supported cameras even though the AppStore description claims it is supported. Disappointing. The app is easy to use and presents the data in a clean manner.

Basic, but does the job. As titled, a simple depth of field calculator that does the job. Good correlation with published tables and there's enough circle of confusion options (cameras and numeric values) to satisfy anybody. It doesn't however directly address the more common query where given a near and far distance you're after a focal distance and aperture. If there's any issue it's the odd choice of fractional aperture values which are unlikely to tally with any camera. It would be great to have a setting to specify full, half and third stops. An optional lock on the focal length would also be handy. Other than this it looks good and works well one handed.

Excellent, supports 2 camera simultaniously. I really like that it can switch between my choice of 2 cameras. Also the graphical display is easy to understand at a glance. After I got this app, I deleted my other DOF apps. Also good that it supports both iPhone and iPad with only one purchase. I have one request though: Could you also show lens "equivalent" mm for non full frame cameras? The app already knows the sensor sizes for a large number of camera bodies, so it would be simple to add in brackets, the equivalent focal length. This could disappear if a FF camera was selected. E.g. for APS-C the focal length could show 23 (35) mm, indicating that actual focal length selected was 23mm, which is equivalent to 35mm on a film/full frame sensor camera.

Great. This app is simple and effective. The UI just works without any unnecessary cruft. The developers are lightning fast at adding new cameras on request. Great!

Really good app for students. Fanastic application that is very simple to use. Simply select your camera, and put in the necessary details (lens focal length and focusing distance) and you are given your focus limits instantly! I reccomend this for students who need a bit more time understanding this type of photographic theory. It's very straight forward and a pleasure to use!

Simple functional App. Great and easy to use app, all the basic settings and values easily accessed and read, best out of the ones I have tried. The only problem is dept of field or focus distance when below 1Metre level needs to read in millimetres. eg 500mm or 100mm not 0.50m which is awkward. I am frequently using a Canon 100mm macro lens that can have a DoF in the mm range however this app won't display these small values which limits the usefullness of the app severely for me.

Great photography tool. This app does exactly what it says it does. It's simple and extremely effective when used in the field. Would reccomend to any photographer!

Great tool. As a beginner, this tool has been very helpful when going from the standard point-shoot to playing with the manual modes on a DSLR.

Really Handy!. This is a very good app for D of F. It is easy to use and understand. It includes all the latest cameras and will update and download more as they are available. Heat app!

App crashes. App crashes on start. Look forward to a bug fix.

No frills - Perfect for the job. This is a simple to use DOF calculator with hundreds of listed cameras available from within the app. Very quick and intuitive controls make this app a pleasure to use. Support is quick and helpful (my camera wasn't listed - an email to the developer resulted in my camera being added to the database the same day) An excellent app that does exactly what it claims to do!

Very good. I like apps that do exactly what they are intended to do. The interface is straight-forward, and the results are presented in a simple pictorial way. Pleasure to use. Thank you.

Awesome support. Downloaded the program yesterday Our camera was not in the list Yesterday we wrote to the support and today we had it included! The app works very well

No macro lens support. I really needed this for macro but it doesn’t allow for that type of lens.

Hyper Focal distance is incorrect. It looks like a handy app. However, the Hyper Focus distance calculated is greater than Focus Distance, for example HF distance is 12.66 m, while focus distance is 3 m.

Exactly right .... Thanks for a great app - visual representation and app style also very clean and easy to understand - *extremely* responsive Support as well with respect to adding new cameras on the market sooner rather than later. Keep up the good work!

Bummer. Bought and paid for app. Appeared to download but no app in my phone. When I click Open in the App Store, nothing happens. Where is my purchase?
