New for iPhone Duo: stand it up, open it like a book or fold it closed. A live scene shows what stays sharp as you change distance, aperture and lens. Calculate depth of field before you take the shot. Choose your camera, then adjust subject distance, aperture and focal length with three horizontal sliders. See your focus limits update as you move. SEE WHAT STAYS SHARP A live scene shows your settings at work. Flowers, a dog, a house and distant mountains sit at real distances, and each blurs according to your focus distance, aperture and lens. Open up the aperture and watch the background melt; zoom in and the scene tightens. You can turn the scene's animation off in Settings. MADE FOR IPHONE DUO Stand it up and the results face you while the sliders lie flat under your thumbs. Open it like a book and results and controls each get their own half, clear of the fold. Close it and everything moves to the outer screen, with your controls in the side bar. Layouts move smoothly as you fold. READ YOUR FOCUS RANGE See the near and far focus limits, total depth of field, and the distance in front of and behind your subject. Check hyperfocal distance when planning a landscape or a scene with distant detail. CHOOSE YOUR CAMERA Browse profiles for modern digital cameras, vintage cameras and film formats. Each profile supplies the circle of confusion used in the calculation. ADJUST WITH ONE HAND Keep settings and results on one screen. Work in metres or feet and inches, with optional aperture snapping and haptic feedback. START WITH THE INCLUDED PROFILES DOF Slider includes free camera profiles and standard calculation ranges. Additional camera packs and macro, telephoto and extended distance ranges are optional one-time in-app purchases. Restore existing purchases from Settings. No ads. No subscription. No sign-in required. Calculations work offline with the available camera catalog; catalog updates and purchases need an internet connection.

Readings unofficial for NIKON D780

The only settings available are for the NIKON D750 and the NIKON D 700. My camera NIKON D780 is not available. I tried to set in for NIKON D7 50 but they are in effect not very accurate. But I must say at least sometime I can vary the differences for usability.

I don’t get why this isn’t better rated, although the brutal ads may be part of it. I discarded it at first because they were so frequent, it seemed like a spammy junk app. After trying all the other DOF apps I reluctantly came back to this one and for some reason got way fewer ads so I could actually test it out.Wow, what a great interface! Clean, clear, simple. Easy to read big numbers and one-handed operation. Actual 1/3-stop adjustments for aperture, not just a decimal number you have to fiddle with to get right. a usable focus range, that reads out in sensible units. All the info you need and none that you don’t.This is the one you’re looking for.

This app has two main issues

Hello app makers!This app has two main issues:1. Too much data sharing. I value privacy a lot, and there's no reason an app should be entitled to my data. What I do on my phone is 100% my business, not anyone else's. There should absolutely no background non-consensual data sharing within the app. Having it listed on the app's download page is not consent, since it's treated as "normal," and it does not ask confirmation.2. Hundreds of out in the open purchase buttons within the app. This is just a bad user experience. Do you really think anyone wants to scroll past hundreds of purchase buttons while using an app? Not only is it cluttered, it also makes it more likely that someone would make an accidental purchase that they didn't mean to. That is the last thing a person should have to worry about in an app. When I download an app, the transaction between you and me is over. If you want money, ask for it up front. Don't hide it within the app. If you don't ask for it up front, I will never purchase anything within the app.Apologies for the strongly worded message. I have seen so much of this online, I have lost patience for it.

Good but missing latest Sony Camera

Good easy to use app on my iPhone. However, disappointed to see that the latest Sony a7 iv model is not available… and I already paid the extra $1.99 for the Sony cameras. To note, the Sony a7 iv started selling in October 2021, so it’s been almost a year!!!Hope you can add this model soon! Please!

Made for iPhone Duo, and a whole new look. • iPhone Duo: stand it up and the results face you while the sliders lie flat; open it like a book and each half gets its own column; fold it closed and your controls move to the side bar. Layouts glide as you fold, and a little aperture iris opens with the hinge. • A live scene shows what stays sharp. Change focus, aperture or lens and the landscape blurs to match, with a very good French bulldog as your subject. Turn its animation off in Settings if you prefer. • A redesigned calculator: a big depth of field readout, near, focus and far limits at a glance, and numbers that roll as you drag. • Camera, settings and search now live in the navigation bar, with a new camera search. • Resizable windows on iPad and fixes throughout.

Version 2.8.0 Oct 20
