How to Fix SANDMARC Lens Blackouts!
Are you attaching a SANDMARC lens to the standard lens and the lens seems to block the camera? Don't worry- your lens isn't broken or damaged. It's because the lens is triggering the Macro Mode on the iPhone and causing a blackout or partial eclipse. To fix this, you'll have to make enable the feature called "Macro Control." This will allow you to toggle off Macro Mode when it occurs un-expectantly.
To enable, first what you're going to do is go into settings, go to camera, then scroll all the way down until you get to macro control. Then tap to enable. Once you do this, open the camera app, and when macro mode turns on, you will press press the flower icon on the screen to turn it off. The iPhone camera will then focus through the SANDMARC lens.
