The Sandmarc 72mm accessory adds 3x optical magnification to a compatible iPhone telephoto setup. I compared its handling with the earlier 48mm version and liked how little additional bulk came with the extra reach.

More reach in a compact kit
The newer lens is only slightly longer than the 48mm version in my side-by-side demonstration. I see it as a useful option for distant landscapes and other subjects you cannot easily approach. It is not a close-focusing accessory; my approximate focus-distance comments in the video are observations, not a measured specification.
App and mounting choices
I use Moment to select the intended phone camera. The threaded case gives a straightforward mount, and the video also demonstrates a clip-style alternative. My thin case had an Ohsnap magnetic accessory added to it, so the magnetic charging arrangement shown is my modified setup.
Filters and my verdict
The system includes options for filters, and I discuss my experience with polarization and mist effects. I enjoyed the compact form and extra reach. If you need less magnification, the 48mm option remains worth considering; the video shows the size comparison and how the accessories attach.
