Simple DoF Calculator Reviews

Outstanding

NHLinh

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...

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.

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.

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.

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.

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!!!

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).

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!

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.

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.
