The case for my iPhone 6S arrived today, and I thought I might share a little about it. It's not the average case, you see. It's from a company called Moment, and it's part of a system that includes the phone itself, three optional lenses (wide, tele, and macro), and the Moment app. The concept is really pretty neat. In addition to protecting the phone, the case has a bluetooth "shutter" button that works in concert with the app to make a camera that acts a lot like ... a camera. In it's most basic operation, you hold the phone pretty much like a regular point-and-shoot camera, and half-press the shutter to autofocus and set the exposure. When you're happy, follow through and click. Neat.
The case also has a special bayonet mount that takes a lens. I got the wide lens with my order, and it is supposed to approximate an 18mm lens on a "full frame" digital camera. So far, the lens seems very sharp, and attaches firmly to the mount on the case. Lenses can be used without the case and with any camera app you like, and they include a mount plate for adding the lenses to cameras without the Moment Case. I requested a mount for an iPhone 5, so I could try it out on one of our older iPhones.
The only thing I don't like about the Moment Case is that the shutter button doesn't work with other camera apps. 645 Pro does work with certain other triggers, so I could see it being able to support the Moment Case in the future, and I wouldn't imagine it would be too hard to get other camera apps to work, too.
