[QUOTE="SuperDave, post: 2298182, member: 1892"]I'm unsurprised by the quality of some smartphone cameras; there are a few out there which can easily produce gradable images of coins.

So that's my biggest worry about the Kickstarter project here, the quality of the optics they'll be using. The provided images are not remotely large enough to evaluate the thing in the context of numismatic imagery needs, although the ~$150 price point is sufficient to expect decent optics.
