I have used a few clip on style camera lens adaptors in the past and although they work okay are prone to moving if nudged and always obscure part of the screen with the back of the clip.Having recently upgraded from an older iPhone to a 17 Pro - partly for the hugely capable camera - I was very keen to test out this new mount and VND filter from K&F Concept.As with the other products I have received from the company there is an immediate feeling of quality with this mount. It snaps onto the MagSafe interface essentially self locating and is instantly ready to go. Once attached it feels solid and secure. It does look a little 'unusual' and the 58mm interface is quite large given how small and tightly grouped the iPhone's lenses are but does of course open up the option of using all sorts of standard camera lenses.The included VND2-32 filter is part of K&F Concept's well regarded Nano-K range and with five steps allows for great control over light levels when filming in brighter conditions.There is also a good quality semi-rigid carry case included with enough space for a few more lens filters as you add them to your collection.If you have an iPhone 17 Pro and are planning on getting a bit more serious with the camera then this is a great addition and good value priced at £35 (£39 with 10% voucher).
