The customized camera window will help you to see the exact framing of your future shot. Just select the focal
length of the lens and choose if you will be using a tele converter.
This app will help you to estimate your future shots even without the camera proper, only having your smartphone / tablet in your hand.
If you want, you may save the picture you see in your camera for future reference. Note that the number of captured frames is limited in this free app.
There is a constant middle-speed auto focus engaged to keep your images focused.
The app has ads in it.
To get rid of ads, increase the scope of supported cameras to Black Magic Cinema, 4K cameras, as well to Canon, Nikon and 4/3 formats, to use all available boosters / converters and to capture frames without limit please purchase to advanced Magic Universal ViewFinder app.
Please keep in mind that this app will perform best on the devices oriented for HD or Full HD display. On older and smaller devices this program may perform awkwardly.
