DoF Calc

Works grate love it!

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?

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)?

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

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.

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

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

How can we do if there is not our canera?!!

Too few cameras, bad GUI, not really useful

excellent

Easy to use, great app

Does nothing.

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.

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

Very good

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

No listing for this camera

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

Easy to use, great app

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

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 ?

Please add info about Dof "In front of the subject" and "Behind subject" Excellent tool Tnx .

Great tool. Very simple ui and easy to use. No extras just what you need :-)

Is listed as requiring no permissions, but installs with access to read_phone_state and modify SD. Why? Removed. There are just as good apps that are more honest.

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.

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.)

Can you add tilt shift lens calculatiins

Really nice with dialers instead of manually entering the values....Five stars

If your into photography I recommend you get this app. It's really simple to use and understand. I always use it to determine the hyperfocal distance of my landscape shots

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.

No ads, and no permissions needed, that's a plus. Simple and useful interface

One question, the nikon dslr option.. Is that crop factor cameras of full frame?

No aps-c sensor

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).

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.

Simple to use, simple to run...

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.

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.
