Common error I use this but be aware that almost all of these apps have the same problem. a crop sensor or a full frame sensor makes absolutely no difference in the depth of field. The difference occurs because on a crop sensor you must be farther away from the subject for the same basic framing. The difference is because you're farther away, not because you have a crop sensor. The distance is what makes the difference.

This is by far one of the most flexible DOF calculators I've tried with respect to it's ability to mix and match distance units. I am very bad at judging distances in meters and much prefer feet but all of my Canon lenses are marked in that dark green on black which is next to impossible to read. This calculator allows me to use the highly visible white meters scale on the lenses to reference the distance, and it calculates the DOF in the more familiar feet or inches or cm or m. A big plus! Where I believe this calc falls short is the coarseness of the spinner dials for the distance. These dials should change the minimum unit adjustment as the reference unit changes and should be less coarse or have an option to change the coarseness. As it is now, there is no setting for 15ft., but if you are good at math it does have 180 inches. I prefer not to have to do the math. With this one limiting drawback I rate it 4 stars, without it, I would gladly pay a premium and rate it 5.

Complete waist of an app! Does nothing.

Note to users If you're talking 35mm sensor size focal lengths (99% of us), then make sure to pick a full frame camera even if you have a crop sensor. If not, the results will be wrong. e.g. A 50mm lens focused to 10 feet will have the same depth of field regardless of your sensor size.

Do what has to do. Easy take on hands No ads, and no permissions needed, that's a plus. Simple and useful interface

Good layout easy to use One question, the nikon dslr option.. Is that crop factor cameras of full frame?

Understanding lens fl Using it for apsc sensor camera. If I got a lens fl of say 16mm in apsc. Should I be using the value of 16mm on the FL input or its 35mm equivalent (24mm)?

If you understand dof, this as simple as it gets. A must have in my bag.

Poor Too few cameras, bad GUI, not really useful

Missing Camera. Good app, but missing many sony cameras, including the a6000.

Small, easy to use and doesn't require special permission.

Panasonic micro 4/3 No listing for this camera

Limited camera database No aps-c sensor

Not all the camera!!! How can we do if there is not our canera?!!

Question? What if I am at a distance between 10 and 20 feet?

Excellent! Easy to use, works well and - best of all - ad-free!

Super little app. I use it on my galaxy 3mini and tab2

Simply it does what it says... no ads, no permissions, nothing. Well done.

Easy to use, great app

Works grate love it!

Very good

excellent

Does not work on all devices Works great on my phone at 800x480. But on my 7" tablet at 1280x800 the f number just displays 1. or 2. without the number past the decimal point. That makes it quite useless on the tablet, which is where I would like to use it. Contacted the developer with this problem, but still not solved. Thus, beware. Just might work great, or not, based on your device.

Useful app with a problem. The app is simple and easy to use but according to my phone it uses a lot of data. No idea why it needs to do this, until I figure it out I can't recommend the app.

Not too complicated Easy to use once you've set your camera's sensor size correctly, you may have to check this first - Google your camera model and the words 'sensor size'. The app uses scrolling dials that make getting your input right easy. Excellent app! I have emailed the developer to maybe add extra sensor sizes as in my case it wasn't obvious which I should use.

Clear and simple I like this application for its simple and clear calculations. Spin wheels let you quickly enter the focal length of the lens, aperture used and focus distance and then calculates all you need to know. If you don't like the result then just adjust one of the wheels to get what you need to set up your camera. A delight to use and highly recommended,.

Accurate but Unusable I checked the accuracy and found DoF Calc to be accurate, which shouldn't be taken for granted since most people don't understand the math behind DoF. For example, f/11 is more accurately f/11.313708 when doing the calculations. And the equations are often simplified, giving very small errors in DoF. Unfortunately, the app is unusable for me since the distance wheel jumps from 10 to 20 feet (the change in DoF for those two values is huge) and I have to convert from feet to inches when shooting at 15 feet in order to get closer to the actual DoF. That wheel needs to be fixed with more values, especially at the close distances. On the other hand, the focal length wheel increments in steps of 1 mm from 1 to 70 mm which is unnecessary since the focal length has almost no affect on DoF (assuming a constant magnification).

Couldn't be simpler I shall look no further. Easy to use and does the job. Good app. Sony Xperia phone.

Do you already understand DoF and need a guide for aperture selection? This app is a simple app, it's not flashy but it's solid and easy to visualize the needed info. Also, it requires no special permissions. The key features are it's ability to show near and far focus distances once the user inputs the focal length and aperture. The point of this is to let the photographer know that at 10 feet and 200mm/f2.8, the DoF is only 1.45 inches (full frame). If you focus on your subject's nose, the eyes are on the ragged edge of being out of focus. That's no good, so what aperture allows a slightly sloppy focus to be more forgiving? Well f4 is only 2.05 inches, that might still leave the eyes out of focus if you're not careful. At f5.6, DoF is 2.9 Inches, which is probably sufficient to be forgiving if you're not dead on with your focus. Obviously, focusing on the eyes saves a lot of trouble, but sometimes you're going to be unsure if a wide open aperture is going to be an issue regardless of how careful you are. It's a solid app and convenient.

First one that worked I checked half a dozen others before this app worked with my Panasonic GX7. $5 thank you :-)

Awesome tool! This is great, and works fine on my RazrM. Thank you!

No special permissions required Simple to use, simple to run...

Useful Simple and easy to use. Thanks

Best DOF calculator for Android!!! YEAH!! In short... LOVE IT!!! Took me just minutes to realize the quick and easy usefulness of this app. I've tried quite a few of available DOF calculators for Android and this one exceeds them all. The scroll wheels are the perfect interface and I love those instant results. Having the 1/3 aperture increments is just right too. I had initially wondered about the Nikon DSLR selection for my D7000. Almost all Nikon DX format DSLR's have the same CoC of 0.020 which is exactly what is selected. No need for extra fussing around. As long as there's no issues with crop factor, this will serve my purposes perfectly.

Nice app Useful and I like the scroll wheel. Other DoF apps didn't have as many f stops, so this was a plus. One negative - can't contact you without an email. ;) I'd like to see the Canon 60D added, please! (Would have given 5 stars had you had more cameras listed.)

Excellent App! This is really useful. Just one thing, does anyone know if I enter the focal length of the camera lens, or the 35mm equivalent? My G1 has a crop factor of 2, so if I have my 20mm lens fitted, do I enter 20mm, or the 35mm equivalent of 40mm? If it's the 35mm equivalent, what's the individual camera setting (dslr) for?

The best Once I found this i deleted all other dof scales I had installed. Easy to use and simple diagram that gives you all the information you need. Major benefit is that it has every focal length for the lower range (up to about 70) and third of a stop increments for aperture.

Very user friendly There are many DOF apps out there, but this has got to be the easiest to use and read. No huge, crammed tables full of figures taking up the whole screen, just an easy to read line that changes as you adjust the parameters. I also like that it lets you change from metric/imperial on the fly, as opposed to being locked into one measurement via settings. Well done, dev!

DoF Calc Excellent neat app. Easy to use. Version I downloaded also has mounted teleconverter. However after selection seem unable to deselect to no setting. Any help please ?
