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?
Fixed incorrect CoC for generic sensor
