The makers of the Shiftcam lens slider case for the iPhone have returned to Kickstarter to fund mass production of their latest development: the ShiftCam 2.0, an iPhone lens case that offers six integrated lenses in a single easy-to-use package, as well as a set of 'pro' lenses that slide into the same rail system.
Depending on the shooting requirements of a scene, Shiftcam users can pick a lens and slide it into place over the phone's built-in camera, using a sliding mechanism and magnetic lens cap. Shiftcam 2.0 comes with a 2x tele lens, a 20x macro, a 10x macro, a 120-degree wide-angle lens, and a 180-degree fish-eye for the rear camera. There is also a 120-degree wide-angle adapter for the front-facing selfie camera.
The system is available in versions for the iPhones 7/Plus and 8/Plus, as well as the iPhone X.

If you want to move past the 6-in-1 slider, the ShiftCam ProLens expansion set adds that option to the Shiftcam product lineup. This series of individual interchangeable lenses includes a telephoto, wide-angle, 238-degree fisheye, "traditional" macro, and "long-range" macro options.
The lenses slot into the same rails on the Shiftcam case as the multi-lens slider, but offer what Shiftcam is characterizing as "pro level image quality."
Pledging at least $50 on the Shiftcam 2.0 Kickstarter page gets you the basic 6-in-1 lens slider and case, but prices go up all the way to $350 for the slider, a full set of Pro lenses, and accessories. Delivery is estimated for May of 2018.
