"It's a simple item, but it does what it says on the tin, if for a bit of a price premium. It's a disposable camera lens embedded in a 3d-printed locking bodycap. It definitely has tons of character and looks best with a flash. For the price, it would be nice to have a little more polish on the finished product, rather than the typical rough texture and raw look of a standard 3d print job.
Things to keep in mind:
1. The focal length is wide, but the minimum focusing distance is at least a few feet away, so best practice is to use focus peaking to keep your subject in focus and not inch too close, which I found myself doing often.
2. Flaring, ghosting, and other characteristics of disposable lenses are present and expected, so try and work with the flaws of the lens rather than against them."
