The iPhone 7 and iPhone 7 Plus already have a great camera for capturing high quality photos and videos everywhere. With Turnikit for iPhone 7, you can attach your Nikon or Canon lenses to your smartphone to do more with it. The metal case has a tripod mount. An extension kit is available for focusing certain zoom cases.
The Nikon G mount should work with most lenses but you will have to do your homework to make sure your new lens is fully compatible. The Nikon D adapter works with Ai / AiS / AF-D AF-S. You can order yours here.
