Image Junky 4+

Image Junky transforms your camera-mounted iPhone into a parallax corrected viewfinder for any camera or format. Mount your iPhone on your main camera and use it as a live view finder! Enter the offset distances of the iPhone lens from your main camera lens and the app does the math, adjusting the image to keep your compositions accurate. You also get tap to measure LiDar distance information for easy focusing. There are no other apps that have these features. Check out the instruction page for more information on how to mount the iPhone and measure the offsets. Create your own mount or reach out to imagejunkyinfo@gmail.com to buy custom iPhone to camera flash shoe camera mounts.

Image Junky also works as a customizable director's viewfinder that isn't slowed down by unnecessary menus and databases of cameras and lenses we don't need. Create and name your custom cameras by entering their sensor or film back dimensions then enter your custom lens focal lengths and you're ready to go. Access any of your custom cameras or lens sets with one tap or use the one tap for "zoom" mode for the ultimate framing flexibility. Image Junky opens instantly, is easy to control, and is ready for to show you the shot right now!

Works on iPads as well.
