About Magic Sonic ViewFinderStorefront description supplied by Apple.

Magic Sonic ViewFinder presents you a precise framing preview for the real camera/lens combination you'll be shooting with, right where you stand with your iPhone / iPad. It simulates the field of view of digital cameras and can help thousands of professionals in filmmaking at the preproduction.

PLEASE READ: this app does not turn your Apple device into an external monitor, but operates as a stand-alone director's viewfinder.

The app contains ad banners, which can be turned off with additional in-app purchase.

The app is a digital directors viewfinder -- it helps you see the field of view for your future shot. Select the camera from the menu and rotate the wheel to select the focal length of the lens.

Supported cameras:

- Alpha a99 II, 7RIII, 7RII

- Alpha 7III, 7S II, 7R

- Alpha a77, a6500, a6300, a5100

- FS100 / FS 700

- F3 / FS5 / FS7

- FX9 FF 6K / FF crop 5K / S35 4K

- RX100 (1" sensor)

- Venice 6K / 4K / 3.8K

Magic ViewFinder simulates using tele adapters or anamorphic optics on your camera (see menu). From the menu you can also select the aspect ratio of the frame guide overlaying your image.

Magic ViewFinder also lets you apply some commonly used color presets (also known as LUTs)to the live picture, which brings you even closer to the final shot.

When you have found the right view, you may save it for future reference, with additional data like the focal length, date and time and camera / lens information.

While taking a photo, you may lock exposure and turn on and off the auto focus to better control the captured picture.

You can set camera to work in constant auto-focus mode, or lock the focus temporarily. You can also tap the live screen to focus on particular objects (which turns on the focus-locked mode).

White balance may work in Auto, Locked or Manual mode.

If the field of view of your real camera is wider than your in-device camera, the app adds 'padding' around the image, since the device cannot 'see' what is beyond. It is the best solution that we developed first amongst other viewfinder apps.

Please note that position of your iPhone or iPad should correspond to the 'nodal point' of your real lens, which is somewhere in the middle of the lens. This point is, so to speak, the weighted center of the optics.

Ad policy: Ads can be turned off (see below).
