Nice modular lens setup for iPhone
This K&F Concept double sided magnetic lens mount for the iPhone 17 Pro Max looks like a clever way to use real 58 mm filters on a phone instead of relying on software tricks. The magnetic plate design with the cutout around the camera cluster seems slim enough that it should not add much bulk, and the included ND2 32 filter is a nice touch for video shooters who want smoother motion and more control over exposure in bright light.What stands out to me is that it works with standard 58 mm threaded filters, so if you already own variable ND or specialty filters you can reuse them instead of buying expensive phone specific accessories. The price looks fair for a mount plus filter combo.
