LumaBooth v4.0 is a landmark release that brings native Canon and Nikon DSLR and mirrorless camera support to your iPad, along with a wave of improvements to live view, autofocus, sharing, and overall stability.

Canon & Nikon Camera Support

• Added support for connecting Canon and Nikon DSLR and mirrorless cameras via USB, enabling professional-quality captures directly from your camera in all session types

• Added a live view auto exposure option for older Canon cameras that display a dark live view image when using flash
• Added a camera orientation setting so you can shoot vertical photos and videos with an external camera regardless of how your iPad is held
• Improved autofocus behavior during countdown so the camera focuses at the start of the countdown and locks focus before the shot, working consistently across both DSLR and mirrorless cameras
